# Development Guidelines
## Build/Test Commands
```bash
python3 -m http.server 8000 # Test: http://localhost:8000
# No build system - pure HTML/JS project
```
## Code Style
- **JS**: ES6+ vanilla, 2-space indent, semicolons, camelCase methods, PascalCase classes
- **Quotes**: Single for JS strings, double for HTML attributes
- **DOM**: Cache element refs, check existence before manipulation
- **Globals**: Minimize - use class instances for state (e.g., `window.trackingConsent`)
- **Errors**: Use console.log for debug, alert/confirm for user interaction
## Project Structure
- `index.html` - Complete demo with all JS/CSS inline
- `integration-example.js` - Framework integration examples
- `translations` object - i18n with 'en'/'no' ISO codes, localStorage persistence
## Key APIs
```javascript
localStorage.getItem('gdpr-tracking-consent') // 'true' or 'false'
localStorage.getItem('gdpr-language') // 'en' or 'no'
window.trackingConsent.enableTracking() // Programmatic control
document.addEventListener('trackingModeChanged', handler) // Events
```
## Integration Notes
- Google Analytics: Update consent via `gtag('consent', 'update', {...})`
- Cookies: Auto-cleanup of `_ga`, `_gid`, `_gat`, `_fbp`, `_fbc` when disabled
- GDPR compliant by default - minimal tracking until explicit consent

</ul>
<h2>📝 Complete Source Code</h2>
<pre><code>// Check if user has given consent
let hasTracking = localStorage.getItem('tracking') === 'yes';
// Update UI based on consent
function updateUI() {
const btn = document.getElementById('privacyBtn');
const status = document.getElementById('status');
if (hasTracking) {
btn.textContent = '📊 Tracking ON';
btn.className = 'privacy-btn enabled';
status.innerHTML = '📊 Tracking enabled';
// Enable your analytics here
console.log('Analytics would be enabled here');
} else {
btn.textContent = '🛡️ Enable tracking?';
btn.className = 'privacy-btn';
status.innerHTML = '🛡️ Privacy protected!';
// No tracking - site works perfectly!
console.log('Privacy mode - no tracking');
}
}
// Toggle tracking on button click
function toggleTracking() {
if (!hasTracking) {
if (confirm('Enable tracking to help us improve?')) {
localStorage.setItem('tracking', 'yes');
hasTracking = true;
alert('Thank you! You can disable anytime.');
} else {
alert('Great choice! Your privacy is protected! 🎉');
}
} else {
if (confirm('Disable tracking?')) {
localStorage.removeItem('tracking');
hasTracking = false;
alert('Privacy mode enabled! 🛡️');
}
}
updateUI();
}
// Initialize on page load
updateUI();</code></pre>
<h2>🎯 Try It!</h2>
<p>Click the button below to see the consent flow in action:</p>
</div>
<!-- Status indicator -->
<div id="status" class="status">🛡️ Privacy protected!</div>
<!-- Privacy button -->
<button id="privacyBtn" class="privacy-btn" onclick="toggleTracking()">
🛡️ Enable tracking?
</button>
<script>
// Ultra-simple GDPR compliance (exactly as shown above!)
let hasTracking = localStorage.getItem('tracking') === 'yes';
function updateUI() {
const btn = document.getElementById('privacyBtn');
const status = document.getElementById('status');
if (hasTracking) {
btn.textContent = '📊 Tracking ON';
btn.className = 'privacy-btn enabled';
status.innerHTML = '📊 Tracking enabled';
console.log('Analytics would be enabled here');
} else {
btn.textContent = '🛡️ Enable tracking?';
btn.className = 'privacy-btn';
status.innerHTML = '🛡️ Privacy protected!';
console.log('Privacy mode - no tracking');
}
}
function toggleTracking() {
if (!hasTracking) {
if (confirm('Enable tracking to help us improve?')) {
localStorage.setItem('tracking', 'yes');
hasTracking = true;

}
} else {

localStorage.removeItem('tracking');
hasTracking = false;
alert('Privacy mode enabled! 🛡️');
}
}
updateUI();
}
// Initialize
updateUI();

<h2>💡 Why This Works</h2>
<p>
<strong>GDPR doesn't require complex consent management systems.</strong> It requires:
</p>
<ol>
<li><strong>Opt-in by default:</strong> No tracking until user consents</li>
<li><strong>Clear choice:</strong> User understands what they're agreeing to</li>
<li><strong>Easy withdrawal:</strong> User can revoke consent anytime</li>
<li><strong>Functional without tracking:</strong> Site works regardless of choice</li>
</ol>
<p style="margin-top: 20px;">
<strong>That's it!</strong> This simple implementation covers all the basics.
The fancy version in <code>index.html</code> just adds nice UI and features,
but the core principle remains this simple.
