> How can I stop companies from getting my location data?
The steps they list only cover gps data. In my final year at uni, during the capstone fair, I recall one group built a tracking system that relied on Bluetooth or wifi or something (maybe cellular signals?) to identify and track people indoors. I think they pitched it to be used in malls or airports, but really could work anywhere. It was surprisingly robust.
There are other projects that track you by license plate on highways, or by facial recognition. All this is location data too. I don’t think a highly motivated person could avoid location tracking any more without living in the woods

- estaseuropano 5y agoYou don't need to send location data to reveal it. E.g. WiFi signal strength of different devices and cell tower strength or switching are easy points to help locate someone. Google was already prohibited from collecting WiFi data in the EU (with streetview cars specifically, but what would stop them from using any android device...), you can bet they still do it in the rest of the world.
- rufus_foreman 5y agoI'm not on wifi, mostly I'm on a desktop computer with a VPN. I'm not an expert, how much of my location data gets sent when I do that.
- nerdponx 5y agoI once read that Apple and Google actively keep track of Wifi access points so they can map out interior spaces, and also geolocate you even if you have GPS location services disabled. I don't know if that's true, but I wouldn't put it past them.

- nerdponx 5y agoNice. I like how the opt-out is really intrusive, in order to discourage you from doing it. And of course being on a "_nomap" SSID is going to make you easily identifiable anyway, because nobody else is doing it. You wouldn't let a Google rep come to your house and physically map out your home, or note down the MAC addresses of your Wifi access point. Yet people are totally OK with them doing it as long as someone physically doesn't show up to do it.

- throw3849 5y agoWiFi on phone sends periodic pings to discover new access points. MAC is unique...

- goatsi 5y agoThat hasn't been true for years, both Apple and Android devices now use a random MAC for probing pings. https://support.apple.com/en-ca/guide/security/secb9cb3140c/web https://support.apple.com/en-ca/guide/security/secb9cb3140c/... https://source.android.com/devices/tech/connect/wifi-mac-randomization https://source.android.com/devices/tech/connect/wifi-mac-ran...
- amelius 5y agoYour shoes could have embedded RFID tags (perhaps originally intended as a payment/anti-theft method by the store you bought them from) that can be used to fingerprint/track you everywhere.
- notdang 5y agoThis stopped working a lot of years ago, both Android and iOS are randomizing the MAC addresses.
- bombcar 5y agoDepending on when they randomize you may still be able to track.
- mewse 5y agoFor what it’s worth, I’ve been using their bluetooth addresses to track my flatmate’s and my Apple watches for about the last eighteen months (obvs with knowledge and consent from both of us), just to determine whether we’re inside or outside the apartment and trigger some home assistant scripts when we leave/arrive. Our watches haven’t changed their their bluetooth addresses during that time. (The detection is accomplished by having a raspberry pi periodically call `hcitool name <address>` and checking whether it gets a response)
