Privacy Policy
Last updated: April 26, 2026. This page is optimized for mobile reading and summarizes how rthfi.com may process technical, usage and location-related information.
Information We Process
We may process basic technical data such as browser type, device characteristics, IP-derived diagnostics and aggregate usage analytics. If you tap the locate button on the map, your browser may share your approximate device location only for that interactive session.
How We Use Information
Information is used to render the map, improve performance, understand feature usage, troubleshoot errors and support service reliability. Location access is used solely to center the map around your current position when you explicitly request it.
Cookies and Analytics
The service may use essential browser storage for map state, interface preferences and analytics tooling. These technologies help preserve your map viewport, support product measurement and identify reliability issues.
Sharing and Retention
We do not sell personal information. Data may be processed by infrastructure, analytics or map providers that support the application. Logs and diagnostics are retained only as long as reasonably needed for security, operations and product maintenance.
Your Choices
You may decline browser location access, limit analytics through your browser settings or stop using the service at any time. If you believe your data has been used and you would like to be credited, please submit a change in the repository at https://github.com/andreybotkin/railtwin; the updated data will appear on this site in the next release. If you have questions about privacy handling for this deployment, contact the operator responsible for the instance you are using.
Policy Updates
This policy may be updated as the product evolves, additional data sources are connected or legal requirements change. Continued use of the service after updates means the revised policy applies from its published date.
