Ciphre encrypts on your device.
Our servers only ever hold ciphertext.
Type a note or pick a file below. It's encrypted in this browser before anything is "sent" — then you'll see exactly what your plaintext looks like versus the only thing Ciphre's database and storage ever receive.

The server has the ciphertext and the IV — plus routing metadata like size, timestamps and expiry — but never the key, so it cannot turn any of this back into your content.
Now decrypt it — as your other device would
Your other paired device holds the same key, so it can open what the server can't.
