Privacy policy
What the Lineage website and app collect, why, who else handles it, and how to have it deleted.
Last updated October 13, 2026
What this covers
Sean Leonard runs Arcaniss Lineage personally. This policy covers the pedigree tool at arcanissborzoi.com/lineage, its dog and kennel pages, and the Arcaniss Lineage iPhone app. It doesn’t cover the Arcaniss Borzoi kennel pages or the puppy waitlist form.
You don’t need an account to use Lineage. We don’t show ads, we don’t use analytics or tracking tools, and we don’t sell or rent your information.
What we collect and why
Searches and dog records
- What
- The name or registration you search for, Breed Archive links you paste, and the dogs and family trees we look up for you.
- Why
- To find the dog and build its pedigree. Our server sends the search term to Breed Archive and saves the results so the same search is quick next time, for anyone. The shared list of recent searches holds the dogs each search found and a one way code for the search, never the words you typed or who searched. Your device recognizes a search by computing the same code.
- How long
- Saved results are reused for 30 days and the shared list holds the last 100 searches. Saved results are kept until someone asks us to delete them.
Research requests
- What
- The dog’s pedigree: names, registrations, titles, birth dates and parents. No information about you.
- Why
- To find show and field records for the dog and its relatives. We send the pedigree to OpenAI, ask it not to return phone numbers, addresses, emails or owner names, and ask OpenAI not to store the request.
- How long
- Results are reused for 30 days (1 day when nothing was found) and kept until someone asks us to delete them. Dogs confirmed on the site may be researched again overnight so the next person gets results sooner.
Your email address, if you ask us to email a PDF
- What
- The address you type, with the dog and design you chose. In the app you can save a default address, which stays on your phone.
- Why
- To email you the pedigree when research finishes. Resend delivers the email.
- How long
- Until the email is sent. A send that fails is retried up to 3 times within a day. A request that still hasn’t gone out after a day is erased by a daily cleanup. We don’t keep a list of addresses and the address never goes into our logs.
Photos you add
- What
- A photo of your dog for the PDF.
- Why
- On the website the photo stays in your browser and is never uploaded. In the app it goes to our server only to build that one PDF.
- How long
- Not kept. The server uses it in memory for that request and never saves it or logs it. The finished PDF is saved on your phone or computer, not by us.
Owner notes
- What
- A short note about a dog (200 characters, no links or email addresses). It isn’t tied to your name or an account.
- Why
- To show it on the dog’s public page and, if you choose, in the PDF. The note text appears in our request log and in a daily summary email to the site owner so notes can be checked.
- How long
- Until you delete it. Deleting needs the private edit token saved on the device that wrote the note, or you can email us. Otherwise notes are kept until someone asks us to delete them.
“Fix this” reports
- What
- The dog and the detail you think is wrong, an optional note, and an optional email address.
- Why
- So the site owner can correct the record. Your email is only used to reply to you. Reports, including the email, are sent to the owner in a daily summary email.
- How long
- Until someone asks us to delete it. Email us to have a report removed.
App install ID
- What
- A random ID the app makes the first time it opens. It isn’t linked to your name, Apple ID or device identifiers.
- Why
- The app sends it with each request so limits apply per phone, and so notifications and sign in reach the right phone.
- How long
- We store only a one way hash of it, never the ID itself. Deleting the app removes the ID from your phone.
Notifications (app)
- What
- If you turn notifications on: your phone’s Expo push token, whether notifications are on, and the dogs and kennels you follow.
- Why
- To tell you when research is ready and when a dog or kennel you follow has a new result. Expo passes the notification to Apple, which delivers it.
- How long
- Until you turn notifications off or unfollow, or Apple reports the token is no longer valid. A pending “tell me when it’s ready” request is dropped after a day.
Sign in with Apple and Pro (app, when available)
- What
- If you sign in: a hash of the ID Apple gives us for this app. We ask Apple for no name or email and keep neither. If you subscribe: the product, when it expires, whether it was refunded, and a hash of Apple’s transaction ID.
- Why
- So your subscription works on each phone you sign in on. Apple handles payment; we never see card details. Apple sends us subscription updates (renewals, expiries, refunds), and we may ask Apple for the current status of a subscription.
- How long
- Until you delete the account in the app’s Settings, which removes it, its phone links and its purchase records. Cancel the subscription itself in your Apple ID settings.
Limits and request logs
- What
- A one way hash of your IP address made with a private salt (and, in the app, of your install ID), counts of what you used today, and a log line for each request with the dog, the design and how long it took. When you save an owner note, the log line includes the note.
- Why
- To keep daily limits (for example, 5 new research requests per visitor a day) and to fix problems. We don’t log email addresses or IP addresses.
- How long
- Daily counts reset each day. Logs are deleted after 90 days by a daily cleanup. Our host, Vercel, may keep its own request logs, including IP addresses, under its own policy.
What stays on your device
- Website: your recent searches (30 days), dogs you add or import, edit tokens for notes you wrote, and the last few PDFs you made (a day at most). All in your browser’s storage. We don’t use cookies.
- App: the install ID, your settings (including a default email if you set one), recently viewed dogs, recent searches, saved PDFs, your notes and your litter plan. You can clear recent dogs and searches in Settings.
Clearing your browser’s site data or deleting the app removes these.
What is public
Some dogs have a public page at /lineage/dog/…, and kennels at /lineage/kennel/…. They show the dog’s registered name, pedigree, research findings with sources, a Breed Archive photo when there is one, and owner notes. Anyone with the link can see them, though they are hidden from search engines. Dogs you enter by hand or import only in your own browser don’t get a page.
Write owner notes as if anyone could read them, because anyone can.
Who else handles it
These services handle information for us. Each has its own privacy policy.
- Vercel
- Hosts the site, the server code and our storage in the United States (Cleveland, Ohio region).
- OpenAI
- Researches show and field records from the dog’s pedigree. Nothing about you is sent.
- Resend
- Sends pedigree emails to the address you give, and the owner’s daily summary.
- Expo and Apple Push Notification service
- Deliver app notifications using your phone’s push token.
- Apple
- Sign in with Apple, App Store payments and subscription status.
- Breed Archive
- The source for most pedigrees. Our server sends it the search terms and dog links you enter, not who you are.
- Google Fonts
- The website, share pages and pedigree emails load fonts from Google, so your browser or mail app contacts Google when they load.
Deleting your information
You can do most of this yourself: delete a note from the device that wrote it, turn off notifications or unfollow in the app, delete your account in the app’s Settings, and clear what’s stored on your device.
For anything else, including a report you sent, a note you can no longer edit, or a question about what we hold, email suby@arcanissborzoi.com. We don’t keep names or accounts for most of this, so tell us the dog, the date, and roughly what you sent so we can find it.
Where this applies
Lineage is run from and for the United States, and this policy is written for users in the US. It is governed by the laws of the State of Washington.
Changes and contact
If we change what we collect, we’ll update this page and the date at the top.
