Privacy Policy
Last Updated: February 2026
INTRODUCTION
This Privacy Policy explains how information is handled when you use TransitLens.
DATA COLLECTION
GTFS files uploaded or imported by users are processed entirely within the browser using a Web Worker. They are never transmitted to any server controlled by the author.
The application stores UI preferences (theme, layout, panel positions) in your browser's localStorage. This data stays on your device and contains no personal information.
FEEDBACK
When you voluntarily submit feedback through the in-app form, the following information is collected:
- Your message text
- Email address (only if you choose to provide one)
- Browser information (user agent string, page URL)
- Diagnostic data such as console logs (only if you opt in)
- Screenshot attachments (only if you choose to attach them)
This data is stored on Cloudflare R2 infrastructure and used solely to review and respond to your feedback. Feedback notifications are delivered via the Resend email service.
No feedback data is collected automatically — it is only sent when you explicitly submit the feedback form.
GTFS PROXY
When importing a GTFS feed from a URL, the application may route the download through a proxy server to handle CORS restrictions. The proxy streams the feed data directly to your browser without logging, storing, or inspecting any request data. No IP addresses, URLs, or feed content are retained by the proxy.
ANALYTICS
The Software does not use third-party analytics or tracking tools at this time.
If analytics are introduced in the future, this Privacy Policy will be updated accordingly.
COOKIES
The Software does not use tracking cookies.
THIRD-PARTY SERVICES
The application loads third-party libraries from unpkg.com and fonts from Google Fonts (fonts.googleapis.com / fonts.gstatic.com). These third-party services may collect standard request data (such as IP addresses) according to their own privacy policies.
LOG DATA
The hosted application infrastructure (GitHub Pages) may collect standard server logs such as IP addresses for operational and security purposes. The author does not access or process this data directly.
DATA SECURITY
Feedback data is stored securely on Cloudflare infrastructure. GTFS data and UI preferences remain on your device and are not transmitted to or retained by the author.
CHANGES
This Privacy Policy may be updated from time to time. Continued use of the Software constitutes acceptance of the updated policy.
