- detaro 9y agoContact lists. All data the app collects about your device, e.g. device ids, other installed applications. How often/when you use the app. From what IPs you use the app. To whom you are talking how much.
- bikamonki 9y agoWhatsapp messages are only encrypted while on the pipe. The local database on your phone isn't. I know this b/c I have r/w messages to that DB in order to make a hacky API. The app I built needed root privileges but in the newest version of Android it can be done w/out root. Can FB or Messenger apk read that DB? Yes. Can any apk installed on your phone read that DB? Yes. Can it post the data to a web service? Sure. Do they actually do it? I don't know.
