Upload a file. I encrypt it, store it indefinitely, and post you a printed certificate carrying the only key that can open it — then destroy every copy I hold.
Lose the certificate and the file is gone forever, including for me. That's the point.
Built for the things you want to still exist in twenty years: a letter to a child, a wedding film, a manuscript, a voice.
No accounts, no password reset, no back door.
