Privacy Policy
Effective August 27, 2026
Your camera stays on your device. Subway Cardio analyzes movement on-device so you can control the game with your body. Camera frames are not uploaded to us.
What the app processes
Subway Cardio uses the front camera to estimate body pose and recognize lane changes, jumps, and ducks. This processing happens locally on your phone or tablet. We do not receive or store your live camera feed.
If you explicitly enable a diagnostic session recording, that recording is saved only on your device for local playback and troubleshooting. You can delete recordings in the app. Removing the app also removes its local recordings and settings.
Data stored on your device
Workout progress, stage state, audio preferences, calibration, consent choices, and diagnostic recordings are stored locally. Subway Cardio does not require an account.
Advertising and service providers
Subway Cardio is free and supported by ads shown during breath breaks. Google AdMob and RevenueCat Ads may process pseudonymous device identifiers, IP-derived approximate location, ad impressions and interactions, consent choices, app interactions, and diagnostics to deliver, measure, prevent fraud in, and improve ads. Their processing is governed by their own privacy policies and by the choices available to you in the app and your device settings.
Sharing and sale
We do not sell personal information. We share data only with the service providers described above as needed to operate and fund the app, or when required by law.
Your choices
You can revisit advertising consent where available, limit ad tracking in your device settings, delete local diagnostic recordings, or uninstall the app to remove its local data. Regional privacy rights may also apply to data handled by our advertising providers.
Children
Subway Cardio is designed for a general audience and is not directed to children under 13, or the minimum digital-consent age in their region.
Changes
We may update this policy as the app changes. The effective date above identifies the latest version.
