Trailmark
An Android GPS tracker for hikes and journeys. It records your track in the background, cleans it, turns it into statistics and photographs, and keeps the whole thing in one portable file — on your phone, not on someone's server.
Privacy Policy
What the app records, where it is stored, the handful of Google services involved, and how to delete everything. Short answer: your tracks stay on your device.
Read the policy →Terms of Use
The licence to use the app, what you agree not to do with it, and — most importantly — why you should never navigate by phone alone.

No account
Nothing to sign up for. No email, no password, no profile.
No ads, no profiling
No ad networks, no advertising identifiers. Anonymous crash and usage diagnostics only, and you can switch them off.
Local first
Routes live in private storage on your phone until you export or share them.
