Privacy at Palomar
What Palomar collects, where it is kept, who can read it, and what you can ask for
Palomar is a registry of mathematics, not of people, and most of what it publishes is about a repository and a commit. This page covers the part that is about people: what a submitter hands over, what Palomar takes from the repository itself about people who never submitted anything, where all of it lives, and what can still be asked for afterwards. How to submit describes the same arrangement from the submitter’s side; if the two ever disagree, that is a bug, and tell us.
Who is responsible
Palomar is operated by Kim Morrison, who is the data controller for the personal data described here. The word “controller” is the legal one for whoever decides what is collected and why; in practice it means that the decisions on this page are hers to answer for.
Write to privacy@palomar-registry.org about anything on this page: a question, a correction, a request to exercise one of the rights below, or a complaint. That address is read; it is not an autoresponder.
Reading this site
Reading Palomar involves no account, no cookie, and no analytics. The
pages are static files served by GitHub Pages, and they read the
registry itself from data.palomar-registry.org, which is
a Cloudflare Worker. Both of those see the requests any web server
sees, and each handles that traffic as its own controller under its
own terms and for its own platform security and abuse purposes.
Palomar adds no tracker to them and receives no report of who read
what.
These pages can be embedded in a frame on another site, and Palomar does not try to prevent it. It could not: a page served from GitHub Pages cannot send the header that refuses framing, and the content policy each page carries in its own markup has no way to say it. That is acceptable here rather than merely unavoidable, because there is nothing on these pages to act on your behalf: no session, no cookie, no button that changes anything, only registry records being read.
What a submitter hands over
None of this is collected from a reader. All of it comes from someone who chose to submit a repository.
- A GitHub account, at sign-in. The browser route asks you to sign in to GitHub so that Palomar can ask GitHub one question: can this account push to the repository you named? Palomar keeps the account’s login name and its numeric id in the private submission state, and discards the access token; the token is never stored. The numeric id is kept because logins can be renamed and reused, and a record that says only “alice” may later name someone else.
- Free-text context, if you write any. The notes field, for whatever you want the editorial review to know. It is held in the private submission state and shown to the automated review. It is deliberately kept out of the public verification dispatch, and the workflow never reads it. There is one way it can travel: if you go on to register, the review’s comments become part of the public record, and a review answering your note may repeat what it says. Do not put anything sensitive in this field.
- Authorization evidence, if you provide any. Also free text, and this one is public early, not on registration. It travels in the dispatch that starts mechanical verification, and the inputs of a workflow run in a public repository are readable by anyone who opens its page, so your evidence is public from verification onward whether or not you ever register. It appears in the public mechanical report as well, and registration then makes it permanent by putting it in the registry record. The submission form says this where you type it: do not name anyone who has not agreed to be named.
- Your address, while a request is being counted. Starting a submission is rate-limited by connecting address before anything else happens. Palomar passes the address to Cloudflare’s rate limiter as a counting key and writes it nowhere of its own: not into the submission state, not into a Palomar log. Cloudflare sees it because Cloudflare is carrying the request. A second, slower limit is counted per account rather than per address, and it is durable: it lives in the private submission state under a file name derived from your numeric account id. What it holds is counters and times. No rate document in that state carries a name, and the server writes only a fixed list of fields into one, so a name cannot reappear there quietly.
An agent submitting without a browser proves write access differently, by pushing a tag at the submitted commit and posting a gist carrying the same challenge. Both are artifacts on GitHub made by whichever account the agent used, and the gist is how that account names itself. How to submit explains why that route establishes less than a sign-in does.
What Palomar takes from the repository, about other people
This is the part a submitter is least likely to expect, so it gets its own section. A registry record describes a piece of mathematics, and mathematics has authors. Most of the personal data Palomar publishes is therefore not about the submitter at all, and Palomar obtains it from the submitted repository and its metadata rather than from the people it concerns.
What it is. The public entry schema carries a list of authors, each with a name and optionally a GitHub handle and an ORCID; a list of responsible maintainers in the same shape; and, for each mathematical source the work builds on, that source’s title, its authors, named contributors and their roles, and a field recording whether those authors participated in, endorsed, declined, did not respond to, or were never contacted about the formalization. Notes about related formalizations are free text and routinely name people and describe what they did. A record also names the repository and the account that owns it, which for a personal repository is a person’s login. The editorial review’s comments, published on registration, can also discuss named people, because discussing the literature means discussing its authors. And the preserved copy of the source carries whatever its git history carries, which is the name and the email address in every commit, from everyone who ever committed to that repository.
Where it comes from. The submitter’s repository,
principally its
formalization.yaml,
which is where a project declares its authors and its sources.
Palomar also preserves the submitted repository as a public fork under
the PalomarArchive
organization, with an immutable tag at the verified commit, so that
the exact source Palomar checked stays retrievable. Palomar does not
add that data and does not index it; forking is how the source is kept
honest, and the history comes with it.
How you are told. Not individually. Palomar does not write to the people a record names, and for the authors of a cited paper it usually has no way to. This page is the notice instead: it lives at a fixed address, is linked from the foot of every page and from the lawful-request document, and says what is held, why, and who to write to. If it reached you late, or only because you went looking, the rights below are not diminished by it.
Who sees it. Everyone. These fields are in the public record by design, which is what makes a registry entry citable and checkable.
On what basis. Palomar’s legitimate interest, and the public interest, in a durable and checkable scholarly record. The balance behind that, and the three kinds of published personal data it weighs, are set out under the basis for each purpose. What Palomar cannot tell you is that you put them there yourself: a submitter names the authors, and may name someone who never saw the submission, and a commit in the preserved history may have been pushed by somebody other than the person named in it. If you are named in a record and think that balance came out wrong for you, that is exactly what the objection right is for, and you do not need to have submitted anything to use it.
The basis for each purpose
Different parts of Palomar rest on different things, and lumping them together would hide the part that matters: which of them you can stop, and when. Consent covers Palomar’s processing of a submitter’s own data for a submission that is still running, and it stops at registration, which is where the rest of the system draws the line too. It never covered the whole of what happens before that line. Personal data about other people is on legitimate interests from the moment it is collected, because a submitter cannot consent for them, and so are the things that outlive a submission: the public verification run, the retained audit history, and, after registration, the record itself.
- Running your submission, which is intake, the push-access check, dispatching mechanical verification, the editorial review, and holding the private submission record while any of that is still going on, rests on your consent, and covers your own data rather than anybody else’s. You choose to submit, and you can stop it while the submission is still open.
- Keeping the public verification run public afterwards rests on legitimate interests, and did from the moment it was dispatched. You ask for the dispatch, and there is no unpublic way to run it; what it carries is listed below. But Palomar does not delete runs in the ordinary course, and nothing in withdrawal reaches one, so the basis for its staying there cannot be a consent you can take back. The interest is that a mechanical result anybody can open and re-check is what makes verification more than Palomar’s word for it, including for a submission that failed. GitHub’s own retention expires the logs after 90 days, while the run and the inputs it was dispatched with stay. An upheld data-protection request can still reach a run: the lawful-request process treats it as one of the public surfaces assessed in the same decision, and removes or disables it where the request requires.
- Serving a registered record, and keeping it for as long as the registry exists, rest on legitimate interests. Not on your consent, and registration does not make them consent-based either. The interest is named, and the balance behind it set out, immediately below.
- Personal data about anyone other than the submitter rests on legitimate interests from the moment it is collected, as set out in the previous section. It is never on consent, at any stage, because the person it is about never gave any and the submitter cannot give it for them. Withdrawal does not change its basis, and neither does registration.
- Keeping the private submission state for audit, which is what remains once a submission has stopped moving, rests on legitimate interests: a review outcome nobody can reconstruct is an outcome nobody can challenge, including the submitter who wants to challenge it. This is the basis the record’s retained history has had from the start, not one Palomar reaches for when a consent ends.
- Rate limiting and abuse prevention rest on legitimate interests. The registry shares one pool of credentials and API calls, so an unthrottled loop is a way to stop Palomar recording anything at all.
- Correspondence with the privacy address rests on legitimate interests in answering you, and, where what you sent is a data-protection request, on Palomar’s legal obligation to handle it and to be able to show that it did.
What your consent covers, and what withdrawing it does. It covers the first purpose above, and only your own data. Withdrawing stops that ongoing consent-based workflow rather than stopping everything. It really does stop it: no registry record and no editorial review are published, and the private record is scrubbed in the same write that closes it. Withdrawing before registration says which fields go and which stay. What it does not reach is what was never on your consent to begin with: the already-public verification run, the personal data in the submission that is about other people, and the git history of the state, which is the retained audit record.
When withdrawal is available. While the submission is still open, which is most of its life and includes the states where Palomar itself has gone wrong: a dispatch it lost, a review it could not run, a registration that stalled. A submission that broke at Palomar’s end is still yours to close. It is not available in the four closed states: registered, already withdrawn, failed mechanical verification, or a review that asked for changes. So a submission can end without your ever having been offered the scrub. Its private record still holds what it held, on the audit basis above, and the way to reach it is a request to privacy@palomar-registry.org rather than a button. Starting a replacement submission for the same repository also closes and scrubs the earlier one.
Why registration is not the basis for publishing. Registering is how you authorise publication. Nothing is registered until you have read your review and asked for it, and the registry schema records the registration instant as the moment that request was acted on. That is a governance act, not the lawful basis for what follows. Consent has to be as easy to withdraw as it was to give, and withdrawing it has to stop the processing. After registration it cannot: there is no submitter-facing takedown route, registration is not reversible on request, and a version leaves public view only by a named Moderator’s decision. A permission you cannot take back is not consent whatever it is called, and a controller may not run processing as consent-based and then reach for a different basis at the moment the consent fails. So serving the record rests on legitimate interests from the first moment it is served.
The interest, named. It is the permanence of a certification record, and through that the integrity of every other entry. What Palomar asserts about a registered entry is that its exact source passed mechanical verification and its automated review identified no blocking problem under a stated contract recorded at an exact policy commit. A registry that can quietly lose an entry cannot support that claim about the entries it still has, because nothing distinguishes a record that was never made from one that was removed. That is why the retention is indefinite and why a suppressed version leaves a date-only tombstone. The interest is shared: by everyone who cites an identifier and expects it to keep resolving, and by every submitter whose record borrows credibility from the fact that records do not silently vanish.
The balance, and where it is written down. There is no separate balancing document. The reasoning is here, and this page is the record of it. What is published about a submitter is deliberately small, since no record names one. Beyond that the published personal data is of three different kinds, and they do not balance the same way, so it would be misleading to weigh them together as though a record were a bibliography.
The first kind is repository metadata and preserved history: the authors, maintainers, cited-source authors and named source contributors a project declares, with contributor roles and, where supported, handles and ORCIDs; the account that owns the repository; and the name and email address in every commit of the preserved fork. The declared part really is what a paper or a bibliography carries about the same people, from a public repository, and Palomar does not enrich, index, profile or contact anyone from it. The commit history is not: nobody puts an email address in a commit in order to be catalogued by a registry. It is there because a preserved fork carries the history it has, and preserving the exact source is what makes the check re-runnable. That is a real interest and a real cost, and the cost falls on people who never chose it.
The second is what a submitter typed: the authorization relationship and the free-text evidence beside it. That names whoever the submitter wrote into it, which may be someone who never saw the submission and has not agreed to be named, and it is public from verification onward rather than from registration. The submission form warns at the point of typing. A warning to one person is not consent from another, so for the person named there the weight rests on the objection right and on suppression, not on anything they did.
The third is generated: the editorial review’s comments, published on registration, which discuss the literature and so discuss its authors, and which can repeat back what a submitter put in the private notes field. Automated text about named people is the kind of processing that deserves the least benefit of the doubt, which is why the review is published redacted, why the page tells submitters to keep sensitive material out of the notes, and why an inaccuracy here is a rectification case and not only an objection.
A submitter arrives at registration having been told that it is meant to be permanent, with withdrawal available up to the moment they ask. The people whose position is weakest are the ones who never submitted anything: co-authors, the authors and other named contributors of cited sources, responsible maintainers, whoever a submitter named in their evidence, and everyone whose name and address sits in a preserved commit history. They chose none of this, so for them the counterweight is not a choice they made but the objection right below, and suppression of the public projection where an objection or another right requires it. Palomar does not claim this balance comes out its way for every person and every record; it claims the reasoning is stated, so you can tell it that it came out wrong for you.
Objecting. Where processing rests on legitimate interests, Article 21 lets anyone object to the processing of personal data concerning them, on grounds relating to their particular situation. Two limits matter. It is a right over your own personal data, not over a record: a mathematical result, a repository, a commit and an automated review finding are not personal data about you, and objecting does not give you a veto over what a record says about mathematics. And it belongs to whoever the data is about, which for most of a record is not the submitter: since a record names no submitter, a submitter’s own objection reaches the account and repository, the evidence they wrote if it identifies them, and their name and address in the preserved commit history. You do not need to have submitted anything to object.
An objection is decided, not automatic: Palomar weighs the grounds you give against the interest above and stops the processing unless it can demonstrate compelling legitimate grounds that override your interests, rights and freedoms, or that the processing is needed for legal claims. Where an objection is upheld, what follows may be suppressing the affected version, removing a field, deleting a preserved fork, or correcting by a new version; it is an outcome the decision may reach, not the measure of the right. A refusal, in whole or in part, names its legal ground, gives you the assessment rather than a citation, and tells you that you may complain to a supervisory authority and go to court. Object by writing to privacy@palomar-registry.org. It is handled under the lawful-request process, which says who decides and what is recorded. There is no form, and no wording you have to get right.
After registration you cannot take it back yourself. Once a version is registered there is no button that unpublishes it, no cooling-off period, and no ordinary takedown route for the person who submitted it. Changing your mind is not, by itself, something Palomar acts on. What you can do instead is register a further version, which is the ordinary way a registered record is corrected and leaves the earlier version resolvable; and make a data-protection request, which a named Moderator decides and which can result in suppression of the public projection, correction by a new version, or more than either where an upheld right requires it. Neither of those is revoking consent. Nor is the objection right a submitter’s takedown route by another name: it reaches personal data about the person objecting, and a registry record is mostly not that. A submitter who simply wants a result unpublished is not asking a data-protection question, and will be told so. Suppression also stops Palomar serving something rather than recalling it; that limit, and what an upheld statutory right can reach, are under correction, takedown, and erasure.
What becomes public, and when
This restates the same section of How to submit, which remains the fuller account.
Public from verification dispatch onward, not from the moment you press submit. Palomar starts the run in a public repository, and the inputs a run was dispatched with are readable by anyone who opens its page, as are its logs. That dispatch carries, exactly: your repository, your commit, the submission identifier, the verification mode, whichever of the optional project paths you gave, the authorization relationship you declared, your free-text authorization evidence if you wrote any, and the Palomar identifier of the existing record if you are submitting a correction to one. It does not carry your notes, which are kept out of it deliberately, and it does not carry the account that proved push access. Whether you later registered is inferable from the registry.
Public only if you register: the registry record and the automated review with its outcome and findings. The record also carries the authorization relationship and the evidence, but those were already public from dispatch; what registration adds is permanence. Withdraw instead and no record and no review are published. The verification run that already ran stays public, with everything its inputs carried; it cannot be recalled.
Not published whichever you choose: your identity as the submitter. The registry record has no field for the person who sent a submission, no schema has one, and registration does not add one. That is a design decision rather than a redaction. Your repository is public and the account that owns it remains as visible as it was before you submitted. What Palomar does not do is put your name in the record.
As How to submit says, “private” here means not public, not confidential. The protocol specification puts the same thing as access-controlled: the material has an audience, and that audience is not only you.
Where it lives and who can read it
The private submission state is an access-controlled GitHub repository. Three parties can see material in it, each limited to what its role needs: Palomar’s operators, who run the registry and decide submissions; GitHub, which hosts the repository and runs the workflows; and the model provider behind the automated review, which receives the material that review is run on. That is what makes it not confidential.
The public registry record is the other side. It is append-only in ordinary operation: published versions are not rewritten, and a correction is a new version rather than an edit to an old one. A named Moderator can suppress one exact version from the public service, which then answers 404 for that version’s record, evidence and render, leaving a tombstone carrying the identifier, the version, and the UTC date of removal, and nothing else. The canonical bytes of what was published are kept privately even then, because a record of what the registry once asserted is the thing that lets a later dispute be settled.
How long it is kept
The packet each automated review runs on is kept for 90 days as a GitHub Actions workflow artifact, and then expires. Public workflow logs follow GitHub’s own 90-day retention.
The submission state records themselves are kept indefinitely, so that any review outcome can still be audited. Because that state lives in git, its history keeps earlier values of the fields as well as the current ones: a value that has been changed or scrubbed is still in the history.
Published records, and the preserved forks of the repositories behind them, are kept for as long as the registry exists. That is what publication means here. That retention rests on legitimate interests rather than on the submitter’s consent, for the reasons given under the basis for each purpose, and it is open to objection on the same terms.
Correspondence with the privacy address is kept while the matter it concerns is open, and while any window for complaining about how it was handled is still open. After that, what is kept durably is a minimum-necessary summary filed with the moderation record: enough to show what was asked and what was decided, and no more.
Withdrawing before registration
While a submission is still open you can withdraw, and withdrawal is not only a change of status: it scrubs the current private record. The basis for each purpose says which states count as still open, since a submission that has already closed without being registered cannot be withdrawn either. The scrub was applied to the records withdrawn before it existed as well, so what it removes is absent from every withdrawn record in the state, not only from the ones withdrawn since.
Removed: the free-text context you wrote and the top-level submitter field are set to null, which is the shape a record with no notes has anyway. The free-text authorization evidence and the login inside the push-access proof are deleted outright rather than nulled, because a record that never carried them has no such key at all, and writing null would invent a shape intake never produces. An event is appended saying identifying details were removed, so the audit trail records that it happened.
Kept: the numeric id of that account, the authorization relationship you declared, and the repository and its owner. The numeric id stays because the integrity checks that keep one person’s submission from being handed to another verify it, and a record without it fails closed rather than harmlessly. Keeping it is a trade and not a claim that the result is anonymous: a GitHub account id is stable, and GitHub will answer who it belongs to without asking anyone for permission. The owner is blunter still: a submission records the repository it named and the account that owns it, and for a repository under your own account that is the same readable login the scrub deletes from the proof. So the accurate description is narrow: withdrawal removes what you wrote and the login from the fields that recorded who submitted. It does not remove your name from the record, and it does not make you unknown.
Unaffected: the git history of the submission state, which retains what was committed before the scrub. Erasing that too is a request under the process below rather than an automatic consequence of withdrawing. Also unaffected is the public verification run, which keeps everything its dispatch carried, listed under what becomes public, and when. Withdrawing does not reach it. Your notes and the account that proved push access were never in it.
Correction, takedown, and erasure after registration
Registration is meant to be permanent, and the canonical history is append-only in ordinary operation. That is the point of it: a citation to a Palomar record has to keep resolving to the thing that was cited. So the ordinary answers to a problem with a published record are not deletion. “Ordinarily” and “meant to be” are doing real work in those sentences: an append-only rule Palomar wrote for itself does not override a legal obligation Palomar is under, and the process below is how such an obligation reaches the ledger.
Requests go through Palomar’s lawful-request process, which sets out who may ask, what Palomar asks for in return, how a request is recorded, and what is published about it: docs/lawful-requests.md in Palomar Policy. Send the request itself to privacy@palomar-registry.org. An Article 21 objection is one of the things that route handles, and the personal data it reaches may be data a served record carries. Whether upholding it suppresses that version, removes a field, or is answered another way is part of the decision rather than given by the request.
The two default outcomes are suppression of the public projection, so the version stops being served and leaves the date-only tombstone described above, and correction by a new version, so the record says the right thing going forward without the old version ceasing to have existed. In both, the canonical bytes are ordinarily retained in the private ledger rather than destroyed. An upheld statutory right can reach that retained data too, and a named Moderator can authorize it: Palomar’s preference for retention is a default, not a claim that the private ledger is beyond the law.
One limit is physical rather than editorial. Records are public and machine-readable, deliberately, and are fetched, cached, mirrored and quoted by people Palomar has no relationship with. Suppression stops Palomar serving something. It cannot reach a copy somebody else already has.
The services Palomar relies on
Palomar is small and runs on other people’s infrastructure. Which hat a provider is wearing depends on the activity, and the distinction is worth keeping.
- GitHub hosts this site, the private submission state, the registry repositories and the public archive forks, and runs the workflows that perform verification and review. It does that work for Palomar, and no processor contract covers it. Palomar runs on a GitHub Free organization account, and GitHub does not offer its Data Protection Agreement on that plan: GitHub’s customer terms say that agreement covers GitHub Enterprise Cloud, GitHub Enterprise (Unified), GitHub Teams and GitHub Copilot, and Free is not among them. Palomar holds none of those and has negotiated nothing separately, so there is no data protection agreement governing how GitHub handles the private material Palomar keeps there. When you visit a page or a repository yourself, GitHub is handling your request on its own account, for its own security and logging purposes, under the GitHub Privacy Statement, and that is unchanged by any of this.
- Cloudflare runs the submission server and the data origin as Workers, holds the public registry projection in storage that is not itself public, provides the rate limiter, and routes mail for the addresses on this site. For that work it acts for Palomar, under the Cloudflare Data Processing Addendum. As the network carrying your request it also processes traffic on its own account for platform security, under the Cloudflare Privacy Policy.
- OpenAI provides the model behind the automated editorial review, which production runs as a Codex engine. Its requests do not carry a reusable provider key: they go through a loopback credential broker Palomar runs beside the review, which holds the real key outside the review’s sandbox, serves exactly one route and one configured model, and refuses stored, background, continued, priority and provider-hosted-tool requests. Refusing stored requests is what it does about retention: the provider is not asked to keep the response object, which is not a claim that nothing is retained at the provider. OpenAI’s published API terms describe their own abuse-monitoring retention, of up to thirty days by default and subject to the legal and safety exceptions they state, and say that API inputs and outputs are not used to train their models by default. Those are OpenAI’s statements about OpenAI’s systems, which Palomar cannot verify; they are not Palomar guarantees. Processing is under the OpenAI Data Processing Addendum.
Cloudflare and OpenAI each process for Palomar under a data protection agreement; GitHub does not, and this is what sits there without one. The access-controlled submission state holds every submission record: the submitter’s GitHub login and numeric account id, the free text they wrote, and the review text written about it. The private ledger holds the canonical bytes of everything the registry has published, including versions later suppressed from the public service. The packet each automated review runs on is kept as a workflow artifact for 90 days, and it is the review’s whole working directory: the private state record, the fully rendered prompts with the submitted material inlined, the raw model event streams and final messages, the normalized per-check results, the spend record, the review as delivered, and, on a run that goes on to register, a sparse clone of the private database. It also holds a checkout of the submitted repository, which is not part of the exposure: a repository has to be public before it can be submitted. A failure or a misconfiguration on GitHub’s part could expose the private parts of that, with no processor agreement standing behind it, only the ordinary terms any free account has.
Where in the world it is processed
All three providers are United States companies operating global infrastructure, so personal data described on this page is processed outside the United Kingdom and the European Economic Area. Palomar does not choose a region for any of them and does not operate servers of its own.
Palomar has negotiated separate terms with none of them and relies on what each publishes. For Cloudflare and OpenAI that is a data processing agreement covering the work they do for Palomar. For GitHub there is no such agreement, as the section above says. What each provider says it relies on, in its own words:
- GitHub states that for transfers from the EU, the UK and Switzerland to countries without an adequacy decision it generally relies on the European Commission’s standard contractual clauses under Implementing Decision 2021/914, and separately that it has certified to the EU-U.S. Data Privacy Framework, with the UK Extension and the Swiss-U.S. Framework. GitHub Privacy Statement. Those commitments are not per plan: GitHub’s terms of service take the Privacy Statement in as part of the agreement, so the absence of the Data Protection Agreement does not withdraw them. But the statement scopes itself to the personal data GitHub handles as its own controller, and the material Palomar uploads about other people is not that. Whether the clauses reach it is a question the statement does not answer, and with no processor agreement there is nowhere Palomar could get an answer. So it is written here as unresolved rather than as a safeguard Palomar is claiming.
- Cloudflare applies the EU standard contractual clauses, deemed amended by the UK Addendum for transfers out of the United Kingdom, and additionally names its certification under the Global Cross-Border Privacy Rules system. Cloudflare Data Processing Addendum.
- OpenAI states its safeguards in its Data Processing Addendum. That document refused to open from the machine this page was drafted on, so rather than write down a mechanism nobody here has read, this line says only where it is. Ask and you will be told what it currently says.
Those documents are the providers’ own and they change, so each one is the accurate statement and this summary is not. A copy of the terms in force for any of them is available on request. If you want to know how a specific piece of your data is handled, ask at privacy@palomar-registry.org and you will be told which provider holds it and sent the terms it is held under.
Your rights
Under the UK GDPR and the EU GDPR you can ask Palomar for access to the personal data it holds about you, for correction, for erasure, for processing to be restricted, and for a copy in a portable form. You can object, on grounds relating to your particular situation, to legitimate-interest processing of personal data about you. Most of what Palomar publishes rests on legitimate interests, including serving and keeping a registered record, so the question is usually not whether the right applies but which part of the material is about you. The basis for each purpose says what the interest is, how an objection is decided, and why the right is not a general power to have a record withdrawn. Consent you can withdraw while a submission is still open, which ends it and scrubs the private record; withdrawing later reaches nothing, because publishing was never based on it.
Ask by writing to privacy@palomar-registry.org. You do not need to have submitted anything to ask. Anything that would remove or change published registry material also goes through the lawful-request process, because those requests are recorded and answered under it.
Palomar will ask you to prove who you are only where there is reasonable doubt about it, and will ask for no more than is necessary and proportionate to settle that doubt. Since the usual case is a submitter writing about their own submission, the usual answer is that nothing further is needed.
One thing these rights are not for. The editorial review is automated, but what it decides about is a submitted repository at one commit rather than a person, and disagreeing with its mathematics is not a data-protection question. About says what to do about that instead.
Complaints
If Palomar handles your data or your request badly, you can complain to a supervisory authority: in the United Kingdom the Information Commissioner’s Office, and in the European Union the authority for your country of residence, place of work, or the place the problem happened. You can also go to court. Neither depends on complaining to Palomar first, though it is welcome, and often faster.
Changes to this policy
This page is a file in a public repository, so its commit history is its changelog: every wording change is dated, attributed, and readable. There is no mailing list to be on, because Palomar does not collect an address to put you on one.
