This app does not collect any personal data. It does not use cookies, and does not track you in any way.
The app does not store any data on your device, except for the settings you choose to save. At this time we don't have any settings to save. Might have later though.
Even though the app asks you for permission to use your location, it does not store it anywhere. It only uses it to show you where you are on the map. Look for the little red dot.
