Here are the most common ones. If yours isn’t listed, feel free to open an issue on GitHub.
Q01 Do I really not need an account?
That is correct. Cnotely stores everything in your browser’s IndexedDB. No servers, no sign-in, no upload of any kind.

Q02 Can I lose my data?
Since everything lives in your browser, clearing browser data, switching devices, or uninstalling extensions will delete it. We recommend regular exports as backups.

Q04 What algorithm powers the memory cards?
We use an SM-2 based spaced-repetition algorithm — the same family as Anki. Each card’s interval adjusts dynamically based on your feedback, surfacing right before you’d forget it.

Q05 Do I have to use both products together?
Not at all. The Note Platform is fully independent; so is creating cards manually. But together, you get the full clip-to-review experience.
