Frequently Asked Questions

Why does my streak reset when I miss today?
Standard streak rules — current streak counts consecutive days ENDING TODAY. Miss today and it resets to 0. The 'longest streak' history is preserved forever.
What about timezones?
All dates use your browser's local time. If you complete a habit at 11:55 PM and travel west, that completion sticks to the original local date.
Can I export?
Not built-in. Data lives at `localStorage['tools-town:habit-tracker']` — copy via DevTools if you want a backup.
