Data Deletion Policy for OsmTrails and OsmTrails Lite Apps
The OsmTrails.com website does not store or collect any user data, nor does it support user logins.
User Data Stored on Devices Only
OsmTrails App stores user data exclusively on the user's own device. No automatic data sharing exists between devices—even if the same user installs the app on multiple devices.
GPS Track Data
GPS coordinates and optional hiking start-stop times are stored within a local database on-device. Users can completely erase this information by selecting the "RESET TRACKS DB" button located at the top left of the app's main screen.
Email Addresses (Optional)
Users can optionally input email addresses to facilitate the easy exporting and sharing of GPS tracks via email apps installed on their device. Such email addresses:
- Can be managed and deleted within the OsmTrails app.
- Are never automatically shared externally.
- Are used solely when a user actively sends GPS data via email.
Phone Numbers (Optional)
Users can optionally provide phone numbers to facilitate sharing current GPS locations via text-message apps on their device. These phone numbers:
- Can be managed and deleted from directly within the app interface.
- Are shared exclusively when the user deliberately chooses to send GPS-location texts through an installed messaging app.
- Are not otherwise shared or transmitted externally.
Cell Tower Signal Strength Data (Optional)
Users can choose to save signal-strength measurements from cell towers along GPS track points. This helps visualize signal coverage where you've already traveled. The "RESET TRACKS DB" button invokes a confirmation dialog that now includes a checkbox to optionally delete all the saved cell phone signal strength data. Note: regularly traveling the same route does not significantly increase data points, as the app is designed to minimize storage usage.
Exported & Imported GPS Tracks
OsmTrails has dedicated screens for managing stored GPS tracks:
- Exported tracks: Managed and deletable individually on their dedicated page.
- Imported tracks: Imported GPX files from your device's Downloads folder can be managed and deleted individually.
Complete Data Removal
According to Android system design, uninstalling the OsmTrails app from your device automatically deletes all user-generated data associated with the application, without the need for further action from OsmTrails.com or its developer.
For any questions or further assistance regarding data privacy or deletion, feel free to contact developer Ron Ledbury.
