Cairn

Privacy

Last updated 2026-05-09

Cairn is a small project by a solo builder. We collect the minimum needed to let you sign in, write cards, and show your handle next to what you write.

What we store

  • Your Google account email, name, and avatar URL — received from Google when you sign in.
  • The handle and profile answers(profession, region, AI usage frequency) you provide at onboarding.
  • The cards you write and the questions you ask, associated with your user id.
  • A session token in an HTTP-only cookie so we know it's still you on subsequent visits.

What we don't do

  • We don't sell your data.
  • We don't run third-party analytics or ad trackers.
  • We don't email you unless you explicitly ask us to.

Deletion

Email the maintainer and we'll purge your account and authored cards. Contact: [email protected].
