Andrognito for Android hides your files with triple-layer encryption
|Developer: CODEX||Download: Android|
|Genre: Tools||Price: Free (with in-app purchases)|
Andrognito hides all kinds of files, including essential stuff like documents, images, videos, archives, and even apps. It's also a stealthy kind of "hide my stuff!" app, being able to lure your intruders into a decoy vault, or launch into an "invisible mode" that hides it from the app drawer and opens it through the dialer. Allegedly, Andrognito also resists brute-foce attacks by automatically locking itself for 15 minutes after 3 failed logins. While we can't know that for certain yet, it should give you some additional peace of mind.
Finally, Andrognito's Automatic Vault Backup feature makes sure you don't lost your data, even in the event of uninstalling the app. Although you will have to unhide it so you can use it again, this is hardly a problem.
