Isn't this primarily on Android ? Am quite certain no app can monitor your location in the background on iOS. Regardless What pisses me off is FB not providing evidence to the contrary, that they don't harvest data in the bqckground. Not providing this evidence makes it quite clear that they do harvest this data. The issue isn't about permissions. 'Sir, may I come inside your house, is fine, but ransacking the house once you get is is douchebaggery.

If Facebook does a background news feed update on your iPhone and notices that your iPhone wifi is on the same IP address as another phone (Android or otherwise) with location enabled, then it can record a correlation. There's probably even better ways of doing it.

  Straight up GeoIP is good enough, particularly on WiFi. On mobile networks I believe the carries will gladly sell the tower-IMEI mapping. They already have to collect that for law enforcement purposes anyway.

    In my experience GeoIP is unreliable. Right now GeoIP identifies my desktop computer as being in northern Nevada. I'm 400 miles away. Right GeoIP identifies my laptop as being in Atlanta. I'm 2,300 miles from Atlanta. Right now GeoIP identifies my wireless hotspot as being in Los Angeles. I'm more than 400 miles from Los Angeles. Three devices, inches away from each other in reality. But GeoIP thinks they're on opposite ends of the country. GeoIP has certainly improved in the last few years, but I would never rely on it for anything important.

> Am quite certain no app can monitor your location in the background on iOS. Any application can do this on iOS, with a few caveats: - iOS prompts you to grant permission when the application requests it for the first time. If you refuse, the application cannot keep prompting you. - After a few days, it reminds you that the application has been accessing your location in the background and asks you if you want to keep allowing it or revoke access. - There is an indicator in the status bar to let you know when an application is tracking your location. - You can see which applications have access and which applications have used that access recently by going to Settings > Privacy > Location Services. - You can revoke access at any time in the same place or by going to Settings > App Name. - You can also only grant applications access to your location while you are using the application, as long as the application supports that. - If an application doesn't intrinsically need location services to function and the developer tries to force users to grant permission by disabling functionality, the application is unlikely to be allowed in the App Store. As others have mentioned, there are also other ways in which applications may be able to infer your location indirectly.
