When you visit this website, our hosting provider automatically collects and stores information in server log files, including your IP address, browser type, operating system, referrer URL, date and time of access, and requested files. This data is used for technical administration and security purposes.
Cookies
This website uses minimal cookies for essential functionality, including theme preferences (dark/light mode). No tracking cookies or third-party analytics are used on this website.
YouTube Videos
Some blog posts contain embedded YouTube videos. These are loaded only after you explicitly click to play, using YouTube's privacy-enhanced mode (youtube-nocookie.com). No data is transmitted to Google/YouTube until you choose to play a video. Once loaded, YouTube may set cookies and collect data according to Google's Privacy Policy.

3. Mobile App Data Collection (Railmap for OpenRailwayMap)
Google Analytics for Firebase
The Railmap app uses Google Analytics for Firebase to understand how users interact with the app. This includes anonymized usage statistics, screen views, and app performance metrics. No personally identifiable information is collected through Analytics.
Firebase Crashlytics
To improve app stability and user experience, the app uses Firebase Crashlytics to collect crash reports and performance data. This helps identify and fix bugs quickly. Crashlytics may collect device information, crash stack traces, and app state at the time of crashes, but no personal data is included.
Location Data
The app may request location permissions to show your position on the railway map. Location data is only used locally on your device and is not transmitted to our servers or third parties.
Map Data
The app displays railway map data from OpenRailwayMap and uses Mapbox for map rendering. When using the map, your requests are processed by Mapbox according to their privacy policy.
4. Data Sharing and Third Parties
We do not sell, trade, or rent your personal information to third parties. Data is only shared with service providers as described above (Google/Firebase, Mapbox) to provide the requested services.
5. Data Retention
Analytics and crash data is retained according to Google's default retention policies (typically 26 months for Analytics data). Server logs are deleted after 30 days.
6. Your Rights
Under GDPR, you have the right to access, rectify, erase, restrict processing, data portability, and to object to processing of your personal data. To exercise these rights, please contact us at alex@alexamin.de.
7. Opt-Out Options
Mobile App
You can opt out of Analytics data collection in the app settings or through your device's ad tracking settings. Crashlytics can be disabled by contacting us directly.
