12-words – File transfer with client-side encryption

In plain words

12-words is a file transfer service that encrypts files on the user's device before upload. Launched in 2015, it's designed for anyone needing to send files securely without relying on the server to protect their data. The service handles encryption locally, meaning only the sender and recipient can access the transferred files. It's suitable for users concerned about privacy during file sharing.
