About this app

PhotoPGP Personal Edition:
o viewer fully supports secure image decryption; even supports images created with the Full Edition
o no public keys - creates photos that can be decrypted with the owner key
o no private storage directory access

Your phone's camera stores image files in public shared storage.
This means that when you take a photo, it can be accessed, analyzed, and shared by other apps on your phone.

How can you control this access to your photos? -- by encrypting them before they are written to public shared storage.

PhotoPGP integrates encryption into the process of capturing an image using the OpenPGP framework for Android (OpenKeychain),
and never exposes intermediate image data to public shared storage.

Using your private-key, the PhotoPGP viewer automatically decrypts your photos securely with nothing shared.


PhotoPGP is used to take photos of sensitive, private, or confidential information such as health, financial, and personal identity records.

o private hand-written notes (ex. password sheets)

o personal identity information

o legal documents (ex. contracts, wills, insurance policies)

o inventory data documenting collections and asset values

o financial and health data (ex. tax records, lab results, receipts)

o proprietary information


PhotoPGP enables you to store your encrypted images safely anywhere (email, thumb-drive, cloud and off-site backup services) preventing tampering and unauthorized access.

PhotoPGP keeps your private data private, and shares only what you want -- in confidence.

New features

V3.2.2565 - Fixed Cached Image Display Issue. New support for Android 10, with continuing legacy support back to Android 2013 KitKat. *** Major change required by Google for new phones/tablets: Apps like PhotoPGP can no longer access public shared directories. Instead, users must now copy files to/from the shared photopgp files directory. Older phones/tablets may continue to allow direct encryption/decryption/signing in the Download, Pictures, and DCIM directories.
