Privacy policy

Effective November 10, 2026 · Emma Junqua and Dani Hardy, Utah

PetThread keeps your pets’ health records in one place. This policy says what we collect, why, who helps us run the service, and what you can do about it. The short version: your records are yours, we use them only to run PetThread for you, and we never sell them.

What we collect

• From the early access form on pet-thread.com: your email address, how many pets you have, and anything you choose to tell us about managing their records.
• Your account: your email address (you sign in with a link we email you; there’s no password) and, if you add them, your name and phone number for your pets’ emergency cards.
• Your pets and their records: the pet details you enter and the records you upload (PDFs, photos and scans), and what PetThread reads from them: visits, medications, vaccines, lab results, conditions, clinics and the like. It also keeps the corrections and notes you add.
• If you connect Gmail: PetThread gets read-only access to that inbox. It looks at emails that have an attachment or a word like “vet” or “vaccine”. For each of those, it keeps the sender, subject, a short preview and the attachment names, and an AI model reads them to spot veterinary records; if it’s unsure, it may read the first attachment. From the records it finds, it keeps the attachments, or the email’s text when the text is the record. What it kept of an email is cleared 90 days after it was checked (the sender of one you added stays with its record), and at once when you disconnect the inbox. It never sends, deletes or changes email. You can disconnect at any time.
• Questions you ask PetThread about your pets, and its answers.
• Feedback you send us, and whether you found an answer helpful, with the page you sent it from, the app’s version and your browser, so we can look into it.
• Which of PetThread’s screens you open, and on which days (such as Today, a pet’s Care tab or Ask), and whether on a phone, a tablet or a computer, so we can see which parts are used. Only the screen’s name and the kind of device are kept, not what was on the screen or which device it was.
• Technical information: basic logs and error reports (such as the page, time, browser and error) so we can keep the service working. We don’t use advertising trackers.

How we use it

• To build and show your pets’ health history, find conflicts and missing records, and answer your questions about them.
• To email you sign-in links, alerts you turn on, and, if you joined early access, a note when your spot opens.
• To keep PetThread secure, fix problems and improve how well it reads records.

We don’t sell your information, use it for advertising, or share it with anyone for their own purposes.

How AI is used

PetThread uses AI models to read your records and emails as described above, and to answer your questions. They’re sent to AI providers only to be processed for you, under terms that don’t let them keep your data or train on it. PetThread organizes your records; it doesn’t diagnose or prescribe.

When you share

If you share a pet’s emergency card by link, anyone with the link can see that card without signing in, including the contacts on it, and open the records it lists, until the link expires or you turn it off. Share it only with people you trust to have it.

When you connect another app

You can connect PetThread to an app such as ChatGPT or Claude so you can ask about your pets’ records there. Nothing is connected unless you allow it, and you choose whether the app may also make changes and add records.

• Once connected, the app can read all your pets’ records, including the full text of each page and the names and phone numbers on your emergency cards. What it opens goes to the app’s maker: for ChatGPT, OpenAI; for Claude, Anthropic.
• OpenAI keeps what you open in ChatGPT, and Anthropic what you open in Claude, under your account with them, on their terms. PetThread’s agreements with its own AI providers, which don’t let them keep your data, don’t cover it.
• ChatGPT may share relevant memories with PetThread. OpenAI may use what ChatGPT gets from PetThread to improve its models while Improve the model for everyone is on in your ChatGPT settings. To turn that off, in ChatGPT open Settings → Data controls.
• Anthropic may use your Claude chats, including what Claude gets from PetThread, to improve its models while Help improve our AI models is on in your Claude settings. To turn that off, in Claude open Settings → Privacy.
• PetThread keeps a list of each connection and of every change it makes (which change, and to which pet or record, never the values), shows them under Connections, and includes them in your export.
• PetThread also counts, for each connection and day, how many times the app used each of PetThread’s tools (such as looking up a pet or a record), so we can see how connections are used. Only the tool’s name is kept, never what the app asked or what it got back.
• You can remove a connection, or turn off its changes, at any time under Connections. It loses access at once. Deleting your account removes every connection.

Who helps us run PetThread

We use these service providers. Each gets only what it needs to do its job:

• Cloudflare: runs the app, stores your files, sends our email and builds the search index.
• Neon: hosts the database, in the United States.
• Vercel AI Gateway, Anthropic and TypeSafe AI: the AI models that read and check records and answer questions, with zero data retention. The gateway may run Anthropic’s models through Google Cloud or Amazon Web Services, on the same terms.
• Google: the Gmail connection, if you choose to use it, reading text from scanned pages and photos, and finding a clinic when you search for one, which sends Google what you type. PetThread keeps only Google’s reference to the clinic you choose, and looks up its address and phone again when a screen shows them. Clinic search uses Google Maps, under the Google Maps/Google Earth Additional Terms of Service and the Google Privacy Policy.
• Sentry: error reports.
• Netlify: hosts pet-thread.com and its early access form.

We may also disclose information if the law requires it, or to protect someone’s safety. If PetThread is ever sold or merged, this policy will continue to apply to your information, and we’ll tell you first.

Google user data

PetThread’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We use Gmail data only to find and file your pets’ records, and people at PetThread don’t read it unless you ask us to for support, it’s needed for security, or the law requires it.

Your choices

• Download everything: from your account, export your pets’ original files and what PetThread read from them.
• Correct it: fix or remove anything PetThread read, from the record it came from.
• Disconnect Gmail in PetThread, or from your Google account’s security settings.
• Delete your account: this deletes your pets, records and files at once. Their copies in PetThread’s backups are removed within 35 days.
• Leave the early access list: use the unsubscribe link in any email, or write to us.

Security

Data is encrypted in transit. Stored files are private, and Gmail access tokens are encrypted at rest. Access inside PetThread is limited to the people who need it to run the service. No system is perfectly secure; if a breach affects your information, we’ll tell you.

So that your records can be recovered after a mistake or an outage, PetThread keeps backups: copies of the database, each kept up to 35 days, and copies of your files, kept up to 30 days after a file is removed. They’re stored with the same providers, are private, and are used only to restore PetThread.

Children

PetThread is for adults. We don’t knowingly collect information from children under 13.

Changes

If we change this policy in a way that matters, we’ll email you before it takes effect. The date at the top shows the latest version.
