Hi
The position is provided by your Android browser.
Which browser (and version) are you using? Which Android version is your device running?
Did you grant "Access your location" permission to WTracks? Your browser should have prompted you on first visit. You may reset it in your browser by going to "Parameters" / "Site permissions" (exact settings names depends on browser and versions)
If WTracks does not have this permission, it is using your IP address to try to guess where you are. But depending on your network setup, it may be completely wrong. Especially if you are using a VPN.
Regards
