We ask for high accuracy location from respective services within device. This is compound information that combines GPS, mobile and wifi information into one and serves it to the app. The only filtering we do within Loquiz is that if location estimated accuracy is worse than 100 meters then we do not allow so activate tasks based on that location.
If your location seems to be incorrect within Loquiz it is adviced to switch from Loquiz to built in map application (Google maps or Apple maps) and see if the location there is the same. If it is then this is the best location information available for all the apps.
