Frequently asked questions
Where is my habit data stored?
Everything is saved to your browser's localStorage on this device only. We never upload your data, and clearing site data or switching browsers will reset the tracker.
How is the streak counted?
A streak counts consecutive days starting from today going backwards. Missing one day breaks the streak, but the longest streak you have ever achieved is remembered separately.
Can I track more than one habit at a time?
Yes. There is no fixed limit on the number of habits, though for clarity we recommend keeping the list short and focused on the behaviours that matter most.
Can I sync between phone and laptop?
Direct sync is not supported because data stays local. Use the export feature to save a JSON backup, then import it on another device.
