Adventures with Google's creepiness on Android continue: I found an entire new section of settings, where I have to tell it not to "learn from this app" - individually, per app.
I'm at the point of shopping for a physical metronome, and seriously considering buying a physical navigation device, just to keep even that data out of Google's (easy) reach.
On that note, is anybody working on an OSM-based equivalent to Garmin/TomTom?
