Local Auto-Save: Your notes are automatically saved to your browser's local storage. This means they persist even if you close the tab or browser, but only on this specific computer and browser.

Sharing Notes (Optional): If you choose to share a note, its content is saved to a secure database (Firestore), and a unique, unguessable link is generated. Anyone with this link can view the note. Shared notes are not automatically updated if you change your local version after sharing; you'll need to share again to create an updated version.

Privacy: Your local notes are private to your browser. Shared notes are accessible via their unique link. Be mindful of what you share.
