Privacy policy

Last updated 3 November 2026

Treemember is a diary of the trees you meet. Your trees are private unless you choose to share one. We don’t show ads, we don’t sell data, and we don’t use analytics trackers.

What we keep

  • Your account: your email address, and the name and picture from Google if you sign in with Google. You can change your display name in Profile.
  • Your diary: the photos you add, when and where each was taken (the location your phone or the photo recorded, or the place you picked), the compass direction for the ghost overlay, and the names and notes you write.
  • Things you do with others’ trees: your likes and the trees you follow, and any reports or feedback you send.

Photos are resized on your device before upload, which removes the hidden data cameras add (including GPS). The Android app also keeps your diary on your phone so it works offline; it stays there until you sign out (after a last backup), delete it or remove the app.

Who can see it

  • Private trees (the default) are seen only by you.
  • Public trees and their photos can be seen by anyone with the link, on Explore and in the Home feed. Their location is approximate (an area about 1 km across) unless you choose to show the exact spot or hide the location entirely. Notes on photos stay private.
  • Your public page (/u/your-name) lists your public trees under your display name. You can turn it off in Profile.
  • When you like a photo, its owner sees your display name in their activity.

Services that help run Treemember

These handle your data on our behalf, only for the purpose given:

  • Clerk: signing in (your email address and Google sign-in).
  • Neon: our database. Cloudflare R2: photo storage and database backups. Vercel: the website. Our server host: the app’s API.
  • Pl@ntNet: when you add photos or ask for a species suggestion, and when a photo of a public tree is checked before it’s shown, a small copy of the photo is sent to identify the plant.
  • OpenFreeMap: map tiles for the area you look at. Photon (by komoot): the place names you search for.

Our hosts keep request logs, which include IP addresses, for a short time for security.

Deleting things

  • Deleting a photo or tree removes it at once everywhere it was shown. Its files are kept for 3 days so you can undo, then removed.
  • You can delete your account and everything in it from Profile, in the app or on the web. How to delete your account.
  • Making a public tree private takes it off public pages straight away.
  • Encrypted backups of our database are kept for up to 8 weeks, so deleted data leaves them within that time.

Children

Treemember isn’t meant for children under 13, and we don’t knowingly keep their data.

Changes and questions

If this policy changes in a way that matters, we’ll say so in the app. For questions, or to ask for a copy of your data, use Profile → Send feedback.
