# Keep My Weight Tracker

A minimalist, privacy-first web application for tracking your weight and daily meals. This application is designed to be simple, lightweight, and focused on data ownership.

## Features

- **Weight Tracking**: Log your weight with optional notes
- **Meal Logging**: Record your daily breakfast, lunch, dinner, and other meals
- **Data Visualization**: View your weight progress on an interactive chart
- **Data Export/Import**: Export and import your data as JSON or CSV
- **Privacy-First**: All data stays on your device using browser's localStorage
- **Mobile-Friendly**: Responsive design works on all devices

## Getting Started

1. Clone this repository or download the source code
2. Open `index.html` in your web browser
3. Start logging your weight and meals!

No installation or setup required. The application works entirely in your browser.

## Data Storage

All your data is stored locally in your browser using localStorage. No data is sent to any server.

- To backup your data, use the "Export Data" button in the Settings tab
- To restore a backup, use the "Import Data" button in the Settings tab

## Technical Details

This application is built with:

- **Frontend**: HTML5, CSS3, and vanilla JavaScript (ES6+)
- **Data Storage**: Browser localStorage
- **Charts**: Chart.js library
- **Dependencies**: None, except Chart.js which is loaded from CDN

## Deployment

### Local Development

Simply open `index.html` in your web browser.

### Docker Deployment

The application includes a complete Docker setup with persistent data storage.

```bash
# Build and run with Docker Compose
docker-compose up -d
```

This will create:
- A container with both the web server and data API
- A persistent volume for data storage at `/data`

### Coolify Deployment

To deploy on Coolify:

1. In your Coolify dashboard, create a new service
2. Select "Docker Compose" as the deployment type
3. Connect to your Git repository or upload the files directly
4. Ensure the volume is configured correctly for data persistence
5. Deploy the application

The application will be available at the URL provided by Coolify. All weight and meal data will be stored in the persistent volume, ensuring your data remains intact across container restarts or updates.
