Habits keeps a running grid of the last two weeks — add a habit, then tap a day to mark it done and watch the streak grow. Everything is saved in this browser on this device only, so no account and nothing to sync. Nothing is uploaded.

A streak counts consecutive completed days ending today (or yesterday if today isn't ticked yet). The grid shows the most recent 14 days with today on the right. Data lives in your browser's local storage; export saves a small JSON backup you can import on another device. Everything runs locally.
