Levels are quartiles of your own maximum, so a 3-page day and a 300-page day both read correctly. Days ahead of today stay empty. Streaks count consecutive non-zero days.

FAQ
Where do I get my data?
Any tracker with a CSV export works — drop the file contents in. If yours has no export, paste screenshots into an LLM with our migration prompt and it will output these lines.
Is the image watermarked?
Only a small URL in the corner. No logo across your grid, no signup wall before the download.
Can I use it for something other than habits?
Yes. It is a date-value grid: commits, workouts, pages read, sober days, practice sessions.
Do you keep my data?
There is no server call on this page. Reload and it is gone.
