habitnix

A free, local-first desktop habit tracker: add habits, tick them each day, and watch streaks and a month grid fill up. Works fully offline.

Key features
  • Habit CRUD: name, emoji (preset grid), one of 8 colors, and a schedule of Daily / Weekdays / Custom weekdays. Edit, archive (history preserved), permanent delete, and reorder.
  • Today rail: today's scheduled habits with big toggles, a live completion ring, and per-habit current-streak flame. Number keys 1..9 toggle the Nth habit.
  • Month grid: habits x days matrix for the current month with < > (and Left/Right arrow) navigation. Filled cells use the habit color, today is outlined, non-scheduled days are…
  • Streaks: current + best per habit, computed only over scheduled days (a weekday-only habit is not broken by a weekend), with today left pending until the day ends. Pure logic…
  • Habit detail: 12-month GitHub-style calendar heatmap per habit, plus stats (current streak, best streak, 30-day completion rate, total ticks) and reorder (move up/down).
  • Reminders: optional per-habit reminder time; a main-process scheduler fires one merged desktop notification per time slot listing only the still-unticked scheduled habits.…
  • Tray + close-to-hide: closing the window hides it to the tray so reminders keep working; tray menu has Open and Quit.
  • CSV export: habitnix-export.csv (UTF-8 with BOM, CRLF, quoted fields) via a native save dialog.

Experimental, unfinished software
This is a personal side project released as an experiment, not a commercial product. It may contain bugs, may behave unpredictably, may stop working after an operating system update, and may be abandoned at any time without notice or migration path.
No warranty of any kind
The software is provided "AS IS" and "AS AVAILABLE", without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. No promise is made that it is accurate, reliable, secure, uninterrupted, or error-free.
You accept all risk
You install and run this software entirely at your own risk. Before using it, back up anything you care about. Tools that rename, move, delete, compress, encrypt, sync, or otherwise modify files can cause irreversible data loss if they behave unexpectedly or are used incorrectly.

To the maximum extent permitted by applicable law, NixBiz and Anand Bhandari accept no liability for any damages whatsoever — including data loss, corrupted or deleted files, lost profits, business interruption, hardware issues, security incidents, or any direct, indirect, incidental, special, consequential, or punitive damages — arising from or connected to your use of, or inability to use, this software.
Unsigned builds and security prompts
Builds are not code-signed. Windows SmartScreen, macOS Gatekeeper, or your antivirus may warn about or block them. Only ever download from an official NixBiz link, and verify anything you run. Never disable your security software on account of this project.
Your data, keys, and third-party services
These tools are designed to run locally, but some features can connect to third-party services you configure yourself. You are responsible for your own API keys, credentials, costs, and for complying with those providers' terms. Any charges you incur with a third-party provider are yours alone.
Not for critical or regulated use
This software is not intended for, and must not be relied on in, any safety-critical, medical, legal, financial, or otherwise regulated setting, nor anywhere failure could cause injury, loss, or legal exposure. It is not a substitute for professional advice or a supported commercial tool.
Free, and no support promised
The software is free to use. There is no service level agreement, no guaranteed support, no guaranteed updates, and no guaranteed compatibility with your system or with future versions.
Your responsibilities
You are responsible for using the software lawfully, for respecting the rights of others, and for ensuring your use complies with any policies that apply to your device, employer, or jurisdiction.

These terms sit alongside the Terms of Service and Privacy Policy. Where a project ships its own licence, that licence governs the software itself.
