2. Hosting

This website is hosted on a dedicated server provided by Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. All data is stored and processed in Germany. Hetzner's privacy policy: hetzner.com/legal/privacy-policy.

3. CDN & DDoS protection

Traffic to this website is routed through Cloudflare, Inc. (101 Townsend St, San Francisco, CA 94107, USA). Cloudflare acts as a reverse proxy and may process your IP address, browser headers, and connection metadata to deliver the site and protect it from abuse. Cloudflare may set strictly necessary cookies (e.g. __cf_bm) for bot management. These cookies do not track you across websites and cannot be disabled as they are essential for site delivery. Cloudflare is certified under the EU-U.S. Data Privacy Framework. Cloudflare's privacy policy: cloudflare.com/privacypolicy.

4. Server access logs

When you visit this site, the web server automatically records:

Your IP address
Date and time of the request
Requested URL and HTTP method
HTTP status code and response size
Referrer URL
Browser user-agent string

This data is collected on the basis of our legitimate interest in ensuring the security and proper operation of the website (Art. 6(1)(f) GDPR). Access logs are stored for a maximum of 365 days and then automatically deleted. They are not shared with third parties except where required by law.

5. Usage-tracking beacons

When you interact with the site (e.g. change luggage dimensions, switch presets or filters), the browser sends lightweight beacon requests to our server. These beacons contain only functional data: the event type, luggage dimensions, selected preset, cabin class, unit, and pass/fail counts. They do not contain any personal identifiers beyond the IP address already present in server logs. Beacons are logged alongside regular access logs and subject to the same 365-day retention.

6. Cookies

This website itself does not set any cookies. Cloudflare may set strictly necessary cookies for security purposes as described in section 3. No analytics, advertising, or third-party tracking cookies are used.

7. External links

This site contains links to external services (GitHub, Ko-fi). Clicking these links takes you to third-party websites with their own privacy policies. We have no control over the data they collect.

8. Your rights

Under the GDPR, you have the right to:

Request access to your personal data (Art. 15)
Request rectification of inaccurate data (Art. 16)
Request erasure of your data (Art. 17)
Request restriction of processing (Art. 18)
Object to processing based on legitimate interest (Art. 21)
Lodge a complaint with a supervisory authority (Art. 77)

To exercise any of these rights, contact [email protected].
