Memory Helper Privacy Policy

The Memory Helper app does not collect the personal data of the person using it.

The only data it accesses are text the files to display images, sounds and text on screen.

It does not modify any of these files. I originally had a plan to allow the user to modify settings files but Android's stupid file permission system made it just too painful.
