# Deklinationstrainer

A daily-practice German declension trainer. Self-hosted so your progress actually saves.

## Deploy to Coolify

### One-time setup

1. Push these files to a git repo (GitHub / Gitea / whatever Coolify is connected to).

2. In Coolify, create a new **Application**:
   - Source: your git repo
   - Build pack: **Nixpacks** (auto-detects Vite) or **Static**
   - Build command: `npm run build`
   - Publish directory: `dist`
   - Port: not needed for static output (Coolify serves it directly)

3. Add a domain (e.g. `deklination.yourdomain.com`). Coolify provisions HTTPS via Caddy/Traefik automatically.

4. Deploy. Visit the URL on any device.

### Local dev

```bash
npm install
npm run dev    # http://localhost:5173
npm run build  # outputs to ./dist
```

## On iPhone

Open the URL in Safari, tap Share → **Add to Home Screen**. It opens fullscreen like a native app, and progress saves in localStorage across reboots, sessions, and app closes.

## Storage

The app tries `window.storage` first (Claude artifact environment), then falls back to `localStorage`. When self-hosted, only localStorage runs, which iOS Safari persists reliably.

To wipe progress: open browser devtools → Application → Local Storage → delete the `gd-v10` key. Or on iPhone: Settings → Safari → Advanced → Website Data → search your domain → delete.
