   @fdroidorg Also, even with geo location off, #UltraSoundCrossDeviceTracking / #uXDT can still track you if you happen to carry a software capable of generating such information (most of the times this is generated by non-free software) or by apps that use the HTML5 "audio" element/tag (since so many apps are just web pages nowadays) with a file whose sound is inaudible to us.
