Privacy and guest progress

Signal City · invited beta

Signal City is operated by Shopsplit Ltd, the controller of your game data. Contact support@signalcity.com for support or privacy requests.

You can play Solo without location permission. Progress and earned powers are saved on this device. Guest progress cannot currently be restored on another device; deleting the app or guest data can lose it.

Online features use an anonymous Firebase account. We store submitted attempts, board/version identity, traffic seeds, signal and power actions, scores and progression needed to check power eligibility. Public provisional standings show a generated guest alias and score, not your email or authentication identifier. Detailed City input recordings expire after 30 days; scores and personal bests remain until deleted or the testing competition is retired.

City map imagery is supplied by Mapbox and online services by Google Firebase/Google Cloud. These services process network and technical request information to provide maps, authentication and the game service. Near me is optional and uses your location to move the map; no location permission is needed to browse or play. Live Scan is not part of this invited beta.

Map requests reveal the area you are viewing to the map provider. Mapbox also collects SDK usage and diagnostic information and may collect location telemetry when location access is enabled. Use the map's information/attribution control to manage Mapbox telemetry. You can revoke location permission in iPhone Settings. Signal City does not use advertising or cross-app tracking, and does not include Firebase Analytics or Crashlytics.

Report a problem shows its contents before you copy or share. We do not silently send reports, screenshots, contacts or device location. Anything you add yourself will be included when you choose to share it.

Delete guest data removes local progress, equipped powers, pending uploads, linked online attempts and standings, then removes the guest account. The app blocks uploads while deletion is pending. A minimal one-way security marker remains to prevent old requests recreating deleted data. Infrastructure logs and backups follow provider retention and are not erased instantly by this action.

Questions or deletion assistance: support@signalcity.com We use game data to provide the service you request and technical/security data for our legitimate interests in operating and protecting it. Optional location access is controlled by your permission. Service providers may process data outside the UK under their applicable transfer safeguards. You may request access, correction, deletion, restriction or portability, or object to processing, by contacting us. You may also complain to the UK Information Commissioner's Office (ico.org.uk).
