The files are encrypted twice with different cipher methods. All your data is encrypted along with the file - nothing is stored on the server. We use a unique encryption system. The files encrypted here can be decrypted only here. Don't forget your password. Otherwise all the ciphered data will be lost.
"Email for decryption notification" is an optional feature that gives you the possibility to receive notifications about the decryption attempts of your files. If you choose to use this feature, your email will be encrypted along with the file - nothing will be stored on the server.
