You control permission - revoke anytime. ### About This Tool Building habits is one of the highest-leverage activities for personal change. The Habit Tracker here is fully private - every check-in lives in your browser's localStorage - so your daily routines are visible only to you. No account, no cloud, no ads, no upsell, no daily limits. Start by adding a few habits you want to do every day. Mark them done with one click. Watch the streak counter climb and the heatmap fill in. Set a goal (21, 30, 66, 90, or 365 days) and the progress bar will show how far along you are. Export to CSV or JSON anytime for backup. Yes, forever free. No signup, no subscription, no daily limit, no ads, no upsell, no paid tier. The whole tool runs in your browser using localStorage. You can track unlimited habits forever. No. Every habit, every check-in and every statistic lives in your browser's localStorage. Nothing is uploaded to any server, no account required, no analytics on your data. If you clear your browser storage, your data is gone - use the JSON export for backup. The current streak counts consecutive days from today backwards where you marked the habit done. The longest streak is the longest unbroken run ever recorded for the habit. A Skip day does not break the streak (useful for travel or illness). Missing a day (marking neither done nor skipped) resets the current streak to zero. Yes. Use the "Pick Date" button in the today banner to select a past date, then mark the habit done or skipped. Streaks and statistics update instantly. This is also handy when migrating from another tool. 21 days to build the initial loop. 30 days for a month of consistency. 66 days is the median time to automaticity from a University College London study. 90 days for habit identity. 365 days for a full year of mastery. The progress bar shows days elapsed versus days remaining. Yes. The layout collapses to a single column on narrow screens. The heatmap still scrolls horizontally. All check-ins work with one tap. Data lives in the same localStorage across devices only if you sign in to the same browser profile - localStorage does not auto-sync between different devices or different browsers, so use Export JSON to move data. Most habit tracker apps require an install, an account, a subscription, or a sync to a cloud service that can later be sold or shut down. This tool runs in any modern browser, stores everything locally, has no account, no subscription, exports to portable JSON and CSV, and never sees your data. AI chatbots cannot track habits for you, push reminders, or build streaks from real check-ins the way this tool does. ## References - [US Naval Observatory — Astronomical Data](https://aa.usno.navy.mil/) - [Open-Meteo — Free Weather API](https://open-meteo.com/)
