LOCAL FILES · NO UPLOAD
A private copy.
A separate key.
This tool encrypts and decrypts writing on your device. It makes no network connections after loading its local assets and saves nothing automatically. Its page policy blocks connections and form submissions.
The hosted workspace is not end-to-end encrypted. This optional encrypted-file workflow does not change it.
Keep the key separately. Anyone holding both files can read the writing. There is no recovery if the key is lost.
ENCRYPT
0 / 131,072 UTF-8 bytes.
Download both files before clearing this page or encrypting again. The matching filenames share a reference.
DECRYPT
File selection reads these files locally. The secret key is never displayed.
This download is unencrypted.
Nothing is uploaded or saved automatically.
Clearing is not a certified wipe of device memory. Device software and browser extensions may be able to read visible writing. A key file is not an account key, wallet key or login passkey.
