Grit is a privacy-focused, client-only Progressive Web App (PWA) for tracking mental toughness challenges, starting with 75 Hard®. It's designed for radical simplicity and focus, helping you stay accountable without distractions or compromising your data.

- Complete 75 Hard Tracking: A simple, satisfying daily checklist for the 5 core tasks.
- Privacy by Design: All your data is stored exclusively on your device in the browser. No sign-up required, no data harvesting, ever.
- Offline First: The app works perfectly without an internet connection once loaded.
- Progress Visualization: A 75-day "Grit Grid" gives you a powerful, at-a-glance view of your commitment.
- Private Photo Gallery: Track your physical progress with daily photos that stay on your device.
- The "Start Over" Rule: The core mechanic of the challenge is built-in, reinforcing the mental toughness aspect of the program.
Grit is built on a modern, client-only architecture.
- Frontend Framework: (e.g., React, Vue, or Svelte)
- Database: PouchDB for all client-side storage, using the browser's best available engine (typically IndexedDB).
- Styling: (e.g., Tailwind CSS)
- Deployment: Hosted as a static site on a platform like Vercel, Netlify, or GitHub Pages.
In a world of data breaches and intrusive apps, Grit takes a different approach. We believe that your self-improvement journey is personal.
- Your Data is Yours: We will never have access to your progress, your journal entries, or your photos.
- No Distractions: Grit does one thing and does it perfectly. There are no social feeds, no ads, and no unnecessary features to pull you off track.
- Built on Open Standards: Using PouchDB and a static site architecture makes the app fast, reliable, and secure.
