Habit Tracker & Streak Calendar (private, printable)

About the Habit Tracker & Streak Calendar (private, printable)

Keep track of the small things you want to do every day or every week: yes/no habits (meditate, no sugar, sleep by 23:00) and habits with an amount (read 20 pages, drink 8 glasses, walk 30 minutes). Tick a day and the tracker counts your current and best streak, how much of the last 30 days you managed, and colours a year heat map — darker for days you reached the target, lighter for days you got part of the way.

Each habit can be due every day, on chosen weekdays (gym on Monday, Wednesday and Friday) or a number of days a week (“3 days a week”, whichever days they are). Start a 21, 30, 66 or 90-day challenge, strict or not, write a short note on any day, and print a monthly habit sheet for the fridge or a journal — blank to tick by hand, or filled in with what you have done. Everything is saved in this browser on this device; nothing is uploaded and you don’t need an account.

Common uses

• Building a morning routine: water, stretching, reading and journaling, ticked in one place.
• A 30-day or 90-day challenge with a clear count of the days done.
• Gym or practice sessions on set weekdays, or a few times a week on whatever days suit.
• A printed monthly sheet for children’s chores or a bullet journal.

How streaks are counted

• Every day: the streak is the number of days in a row the habit was done. Today counts once it is ticked; until the day is over, yesterday’s streak still stands (the page says it is at risk).
• Chosen weekdays: only those days are due. The days in between are skipped: they neither break the streak nor add to it, and a tick on a day that is not due is kept but not counted.
• Days a week: each week that reaches its number of days counts once, so the streak is in weeks. The week starts on the first day of the week in your country (you can change it), and the first week of a new habit needs only as many days as were left in it.
• Amounts: a day counts when the amount reaches the daily target. Less than the target is kept and shown, but does not count for the streak.
• Nothing before a habit’s start day counts. Change the start day to log earlier days.

Challenges

A challenge runs for a set number of days from the day you choose, with every day due, so it is for a habit due every day (a habit with rest days keeps its own streak instead). In a strict challenge a missed day starts it again on the next day, so only an unbroken run completes it; otherwise the page counts how many of the days you did. The habit’s card shows the day you are on, the days done and the days left.

Reminders

• Calendar reminders: give a habit a reminder time and download the calendar file (.ics). Your phone’s or computer’s calendar then rings at that time on the habit’s days, even when this page is closed. The file uses the standard iCalendar format (RFC 5545) with a repeating event and an alarm for each habit.
• Browser notifications: switch them on and allow them when the browser asks. They ring only while this page is open in a tab, and only for habits not yet done that day; a closed page cannot wake itself up without a server, which this tool does not use. Some browsers (on iPhone, for example, outside an installed web app) do not offer notifications to web pages at all.

Printing, exporting and moving to another device

• Monthly sheet (PDF): one landscape page for up to 16 habits, with a box for every due day (a dash marks days a habit is not due), weekends shaded, a total column and lines for notes. Choose a blank sheet or one filled in with what you have ticked.
• CSV: every logged day with the habit, the value, the target, whether it counted as done and the note, for a spreadsheet.
• Backup: one .json file with all habits, days and notes. Open it with Restore from backup on another device or browser to carry on there; restoring replaces what that browser has.

Limitations

• Your habits are kept only in this browser on this device. Clearing the browser’s site data deletes them, and they do not sync: use the backup file to keep a copy or to move them.
• Browser notifications work only while the page is open; use the calendar file for reminders at other times.
• Up to 30 active habits, and about ten years of days for each.
• The tracker records what you tick; it does not judge or rank habits, and it does not block apps or websites.

Privacy

Habits, ticks, amounts and notes are saved in this browser’s local storage on this device and never leave it: nothing is uploaded, and you don’t need an account. Backups, CSV files, the PDF and the calendar file are made in your browser and saved where you choose. Delete all data removes everything this page has saved.
