Sinterkin family archives · 22 September 2026
Each family archive on Sinterkin is private and reachable only by relatives its keeper has invited. This page says, in plain words, what an archive keeps about you and why. There is no advertising, nothing is sold, and the pages contain no analytics or tracking scripts.
Signing in
Sign-in is handled by Cloudflare Access. You sign in either with your Google account or with a one-time code sent to your email. When you use Google, the only things requested are your name and email address; the archive never sees your Google password or anything else in your account. Cloudflare Access keeps you signed in with its own cookie. Their policies: Cloudflare, Google.
What the archive keeps about you
- Your email address, on the archive's invitation list, and linked to your own entry in the family tree so the site knows which person you are. That link is kept in private storage; it is never written into the archive's pages.
- A visitor profile: the display name you choose, your preferences, and a record of what you have contributed and whether it has been reviewed. Only you can read your own profile; no address on the site returns anyone else's.
- Your contributions, if you make any: corrections, stories, answers, transcriptions, photographs and audio recordings, together with the name you give and the email you signed in with.
- A link to a photo album, if the keeper has made one for you in Google Photos and shared it with your account. The archive stores only the link, shown only to you on your own page. The photos themselves stay in Google Photos under Google's policy.
The site keeps the name you typed and your album answer in your browser for the current session only. It sets no cookies of its own.
Who sees it
The archive's keeper, the person who invited you, reviews every contribution by hand. Nothing you submit appears until they accept it. Once accepted, a contribution becomes part of the archive, credited to the name you gave, and can be read by the other invited relatives. Your email address is used to reach you and to credit you; it is not shown in the archive.
Living people
Details about living people are shown only inside the invitation-only archive, to invited relatives who have signed in.
Removing your information
Ask the person who invited you. They can remove your email from the invitation list, unlink you from your entry, delete your profile, and withdraw contributions you no longer want kept.
Contact
Each archive is run by its own keeper. For anything about your archive, contact the person who invited you.
