ChartIt — snippets, templates and the extension that expands them
No clinical decision support: nothing in a pack suggests a diagnosis, a dose or a treatment. Every blank is filled by the person writing.

What is sent is the sealed vault — the same ciphertext that is in this browser's storage. The extension asks for the passphrase itself; this page does not send it, and it has no way to.

Where your snippets are
Open on this device
- The key is a random 256-bit key kept in this browser.
- The stored copy lives in this browser's local storage on this device, as ciphertext.
- Key derivation is PBKDF2-HMAC-SHA256 at 600,000 iterations; encryption is AES-256-GCM with a fresh 96-bit IV per save.
- Sync is off until you turn it on. When it is on, the server holds the same ciphertext and a version number, and nothing else.
- ChartIt sends no analytics and makes no third-party requests.
