TrailFog is made by Motionz Studios. This policy explains what the app collects, why, and how you control it.
Last updated: 28 October 2026
When you tap Start Ride, TrailFog records your GPS position, including while your phone is locked, so it can clear the fog along your route. Recording stops when you tap Stop. Rides are saved on your device. If you are in a group or on the world leaderboard, your ride points (outside your privacy zones) are uploaded so that group members can see your trails and so leaderboard distance and new ground can be calculated and checked for cheating.
Photos are only taken when you tap the camera button. They are saved on your device with the place they were taken. If you are in a group, a smaller copy of each photo outside your privacy zones is shared with that group.
The app creates a random rider ID on your phone. If you use groups or leaderboards, your ID and the rider name you choose are stored on our server and shown to group members or on the leaderboard.
If you sign in, we receive an account ID and the email address from Apple or Google. With Apple you can choose to hide your email, and we then only get a private relay address. We use this only to sign you in and keep your rider, groups and shared trails if you change phones. We never email you marketing and never show your email to other riders.
If you report a rider or a photo, we store the report and its reason so we can review it. If you block a rider, we store that so they stay hidden on any phone you sign in on.
Map images are downloaded from our map provider, MapTiler. Like any website, it receives your device's IP address and the map area being shown, but not your account or ride history.
Shared data is stored with Supabase, our database provider, which processes it on our behalf. We keep it until you delete it or leave, or until it's no longer needed for the app.
If you're in the EU or UK, you have the right to access, correct, delete or export your data, and to complain to your data protection authority (in Spain, the AEPD).
TrailFog is not meant for children under 13, and we don't knowingly collect data from them.
If this policy changes, we'll update the date at the top and, for big changes, tell you in the app.
