WTF?! My non-rooted phone had #Google Maps pre-installed, but I only use #OSMand for navigation etc.

Yesterday, I walked to a local restaurant, without using my phone, and had lunch there before walking back.

I never opened #GoogleMaps.

Today, I find a notification from Maps:
How was {restaurant name}?
Rate places to get smarter recommendations.

So it tracked and calculated where I ate without even opening my phone or the app.

Definitely time for #Pinephone / #LibreM

#privacy #Android

@Blort Did you have Wi-Fi or the SIM cards enabled? Android has a "low power use but inaccurate" geolocation system that can fetch location data without having to turn to the battery-heavy GPS/GLONASS/GALILEO systems. Basically they know which telco cell cover which area, and what APs are available where.

@Blort "Airplane mode" or removing SIMs isn't a solution either as in most countries phones are mandated by law to always connect to a base station and allow calling emergency services... which means there is a base station somewhere which means your device (often called U.E. in the telco world) has some coordinates to fetch (this is how EMS locates your device if you can't say where you are).
