Despite the obvious naughty uses, there are plenty of perfectly legitimate reasons why you might want to give Snapchat a whirl, and they all center on this social app’s near-perfect ability to give you a wealth of control over the privacy of the pictures and videos you send to your friends. Snapchat has become so popular so fast that more than 200 million snaps are being shared per day.

If you’re looking for a photo app that has comprehensive gallery functionality, fun filters or cloud-based storage, this is not the app for you. But if you want to strap the digital equivalent of a time bomb to every piece of media you send to your friends — we won’t ask why — you’ll be happy to know that you’ll be able to set up Snapchat on iOS or Android nearly as quickly as you can say “selfie.” Here’s how.

The Android version of Snapchat also gives you the opportunity to lower the quality of the videos the app takes, as well as Snapchat’s default camera orientation. You’ll find both of these settings buried within the “Video Settings” section.

Finally, to keep your Snapchat log nice and tidy, both Android and iOS versions of the app allow you to “Clear Feed” with just two taps of your finger.
