This article is about the OpenPGP compatible Android app. It is not to be confused with the permission management app Privacy Guard in Cyanogenmod.

Android Privacy Guard (APG) is a Free Software and open source application that runs on the Android Operating System. The application provides strong, user-based encryption which is compatible with the Pretty Good Privacy (PGP) and GNU Privacy Guard (GPG) programs. This allows users to encrypt, decrypt, sign, and verify signatures for text, emails, and files.

The program allows you to store the credentials of other users with whom you interact, and to encrypt a file such that only a specified user can open it. In the same manner, if a file is received from another user from whom you already have stored credentials, you can verify the authenticity of that file (and decrypt it if necessary).

For more information on how the system for encrypting, decrypting, signing or verifying signatures works, see the page for Pretty Good Privacy as this is based on exactly the same algorithms and methods of operation.


After its initial release in June 2010,[2] it has gained a strong following with over 2000 reviews and over 100,000 installs from the Google Play store.[3] Several tutorials have been written which instruct new users in how to setup APG on an android phone.[4][5] These tutorials generally reference APGs interaction with the K-9 Mail Android e-mail client.[6][7]
