What the password actually does
Protection encrypts the file's contents — not a hidden flag but mathematics: without the password, the bytes are noise to any reader, extractor or preview. Interception without the password yields nothing.
The unrecoverable truth
We do not store your password and cannot recover it — nobody legitimate can; that is what encryption means. Keep the original unprotected copy safely archived, share passwords by a separate channel (call or SMS, never the same email as the file). Files are processed temporarily and deleted automatically — there is no general cloud storage.
