Privacy Policy

No version of this app collects any user- or device-related data, and no such data gets transmitted.

The app does
     • determine whether the device has a 32 (no longer supported) or 64 bit processor so as to know the maximum number that can be handled
     • store selected application settings on the device so that those get preserved when the app gets closed and re-opened later.

If you have any questions or concerns please send me an email.
