None. Red Green Light is a fully offline application. It does not collect, transmit, or share any personal information, device identifiers, location data, or usage analytics.
The only data the app stores is the traffic-light change records you enter yourself (timestamps and a direction flag R→G or G→R). These are kept exclusively on your device in the app's local database. Nothing leaves your device.
The app does not make any network requests. It functions without an Internet connection at all times.
The app does not request any runtime permissions. It requires no location, camera, microphone, storage, contacts, or Internet access.
This app does not collect information from any user. It is therefore suitable for users of all ages.
The app does not integrate with any third-party services, analytics providers, ad networks, or cloud services.
