Privacy details

Habit tracker processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Habit tracker explained

Summarize a habit’s binary completion log. Enter the oldest period first, with 1 for completed and 0 for missed. The report calculates completion percentage, the trailing streak and the longest run in the supplied log.

Next: Project management board

Next: Risk register planner

A worked example

11011 means four completed periods out of five, or 80%. Its current streak and longest streak are both two periods.

Before you use the result

Periods have the meaning you choose: days, sessions or another consistent interval. The tool does not infer calendar dates or save your log after closing the page. Download the report to keep it.
