FAQ
Is this private?
Yes — processing runs in your browser; we do not upload your inputs.
Do I need an account?
No — free to use without signup.
Does it work offline?
After the page loads, most tools work without further network calls.
Mobile friendly?
Yes — layouts adapt to smaller screens.
Which AES mode?
AES-GCM with a random IV prefixed to the ciphertext (base64). Use a strong passphrase; this is for local demos, not a full password manager.
