Questions

Can you recover a forgotten password?

No. Nobody can, not even us. Keep the password safe.

Is the password sent anywhere?

No. The file is encrypted on your device.

Do the limits on printing and copying always hold?

Most readers respect them, but a limit is a request, not a lock. Only the password to open the file truly protects it.
