    FAQ

    FAQ

    Where is my data stored?

    Only in this browser's localStorage. Nothing is uploaded, and there's no account. Clearing browser data erases it, so export a JSON backup now and then.

    I forgot to check in yesterday. Can I fix it?

    Yes. Select that habit above the heatmap, then click the day's square to check it off or clear it.

    How are streaks counted?

    A streak is the number of consecutive days the habit was checked. If today isn't checked yet, the streak still counts through yesterday, so you have until midnight.
