Privacy
Your trips stay on your iPhone. Stamp90 has no account and no server of ours behind the app: we never receive your trips, places, location readings or photos.
Photos and locations are read on your iPhone to build your trips, and only the country, and in the US the state and town, is kept for each day. The app goes online only for Apple Maps on the journey map, these help pages and the tour video, and purchases through Apple. There are no ads, analytics or tracking tools in the app.
The full policy is in the app at Settings › Privacy.
