Privacy
Everything runs in your browser: what you type or paste is processed by JavaScript on your device, not on a server. The first time you use it, an open-source library is downloaded from the jsDelivr CDN; your input is still processed locally. If you are signed out, nothing is saved at all. If you sign in with Google, your inputs and settings are saved privately to your account so they sync across devices.
