Please read

Before you install

  • This is early-access software and has not completed an external security audit.
  • Use a test file first. Keep the original until you have created, saved and verified the capsule.
  • Untilum does not keep a backup. Preserve at least two UDDP copies and the password separately.
  • The current Android inline payload limit is approximately 25 MiB.
