It's pretty scary what information you can infer from geolocational data, it's why you should try your best to not use it as much as possible.

When an app asks for your location only give it the minimum geolocation and time if you're absolutely sure it needs it (for delivery make sure there's not a place you can manually enter the dropoff location first, etc).

Also, "fine location" is a much more invasive technology than people think. Apple and Google have giant databases of Wifi broadcast locations and associated positions, which is what gives you the "more accurate location."

If you want to help do your part to mitigate that turn off your router's SSID broadcast and make sure none of your devices attempt to "auto connect" to your wifi.

Sounds kinky

Sooooo. This is actually scarier than it may seem....

You can tell what outlet or building a phone is plugged into sometimes by micro aberrations in power output.

Also interestingly you can kind of tell what webpages somebody visits by their phone's power usage:

edit: for stuff like this they kind of need existing power profiles to like compare against, so this is sometimes used to tell if you're "at home" by identifying the charging profile of the charging apparatus you use at night etc.

Wait if that's the most ridiculous part, then... Does the smartphone even know when it's switched on or off?

Barrier too high for the normie. We need a commercial Graphene OS offering.

But even then the normie will be compelled to install GPS. Can't even fucking get an uber anymore 🤡

Your windows laptop too.

But better go Linux

Couldn't you just, like, turn it off?

Turning off GPS and turning on airplane mode should do the exact same, right? If you don't trust your OS you could use something like GrapheneOS or LineageOS, that's what I do. I don't feel the need to physically stop my phone from collecting data if it's Operating System is free software and built to respect my privacy. That way my smartphone actually does what I want, instead of working against my interests. Constantly fighting against the device you carry all day sounds exhausting.
