FAQ
Frequently asked questions
How are files encrypted?
AES-256-GCM, one random key per file, in authenticated 1 MB blocks. Keys are wrapped with a master key stored outside the database.
What is zero-knowledge mode?
A Pro option that encrypts the file in your browser with your passphrase. The server stores only ciphertext and never learns the passphrase.
Can recipients download without an account?
Yes. Share links work for anyone you send them to, optionally protected with a password.
Is there a file size limit?
Lite allows 25 MB per file. Pro follows your server limits and your plan settings.
Can I get my files back after deleting?
Deleted items go to the trash and can be restored until the retention period ends.
Do you support teams and clients?
Pro adds file requests so clients can upload into a folder without an account.
What happens if I lose my zero-knowledge passphrase?
The file cannot be recovered by anyone. Keep the passphrase safe.
