Maybe I’m paranoid, but I like to keep track of what permissions various apps have on my phone and I like to keep them as limited as possible. The Bouncer app is awesome for this and even though I’ve used it for a couple years, I don’t think I’ve ever written about it here.
When an app requests permissions, you can configure bouncer to automatically remove those permissions immediately when you’re done with the app, after a fixed amount of time or never. So for something that I use all the time like Google Maps, I never remove the permissions, but for something like Untappd or Instagram, I make it request camera permissions from me each time and then Bouncer removes those permissions when I’m done.
The removal happens by automating your user interface so you need to stop touching it for a couple seconds. It can be annoying, but generally it makes me happy because I don’t have to wonder what those apps are doing with my camera or location information in the background.
It’s a free app so it’s worth a shot if you’ve ever had similar concerns.
