Privacy policy
Interchange Offline Metro for iPhone. Last updated 20 September 2026.
The app has no accounts, no analytics, no advertising and no tracking. It does not collect personal data. The detail is below.
Location
The Nearest station feature reads your location once, in the foreground, only when you open it and only after you allow it in the iOS permission prompt. The position is compared with the station coordinates stored on your phone. It is not saved and it is not sent anywhere. You can revoke the permission at any time in Settings > Privacy & Security > Location Services.
Purchases
Pro is a one-time purchase processed by Apple through the App Store. The app receives only whether the purchase is active. It never sees your payment details, name or email. Apple describes its handling of purchase data in Apple's privacy policy.
Network use
Station data is bundled with the app and everything works offline. When the app is opened with a connection, it downloads a small list of network versions and any station files that changed from interchange-offline-metro.pages.dev, hosted by Cloudflare. That request carries no identifier, account or cookie. Like any web server, Cloudflare may record the requesting IP address in its logs for a short time under Cloudflare's privacy policy. Nothing else is ever transmitted.
Data stored on your phone
Downloaded station lists, saved lines, the last line you opened, the line pinned to the widget and your Pro status are kept on the device only. Deleting the app deletes them.
Children
The app collects no data from anyone, including children.
