That makes it ideal for sensitive routines, shared computers you clear after use, or anyone tired of yet another login.
How streaks are counted
A check-in marks a calendar day for a habit. Your current streak counts consecutive checked days ending today, or yesterday if you have not checked in yet. Miss a day and the current streak resets unless that habit has grace enabled, which allows a single skipped day inside the chain.
Best streak is the longest run found in your history with the same rules. Export JSON to back up habits before clearing browser data, and use the printable week view when you want a paper checklist on the fridge or in a planner.
Tips for sticking with it
Keep the habit list short enough that you will open the page daily. Name habits as concrete actions (“stretch 5 minutes”) rather than vague goals. Use the month grid to spot patterns, and turn on a grace day only for habits where life regularly gets in the way once a week.
Private by design
StreakKit has no server-side processing. Your habits stay in this browser and in storage on this device only. Clear site data anytime to wipe them, or export first if you want a backup.
