| Type of information | Source / method | Purpose |
|---|---|---|
| Step count data (read-only) | Android Health Connect | Your step count is converted into the distance you can travel within the App and used as a virtual travel distance on the in-app map. We do not collect or use your actual GPS location. |
| In-app virtual location (in-game coordinates) | Locations you tap on the in-game map, or destination coordinates calculated within the game | These in-game coordinates (not your device's real GPS location) are sent via Firebase Cloud Functions to external APIs to check whether Street View is available at that point (Google Maps Platform: Street View Static API metadata only; the imagery itself is shown inside the Google Maps app and we never receive the image data). |
| Anonymous identifier (anonymous auth ID) | Firebase Authentication (anonymous sign-in) | Used to apply a daily rate limit per user to Cloud Functions calls; Firestore stores only a usage count against this ID. It is not linked to your name, email address, or any other information that identifies you. |
| Device / app integrity information | Firebase App Check (Play Integrity) | Used to detect fraudulent requests or a tampered app, and to prevent unauthorized access to Cloud Functions. |
| Game progress data (step balance, earned badges, travel history, settings, etc.) | Local database on your device (Room / DataStore) | Stored only on your device as data required for the App to function. It is never sent to our servers. |
| Backup of game progress data | Android OS's standard Auto Backup for Apps | If backup is enabled on your device's Google account, Android automatically backs up this on-device data. This is an OS-level feature; the App itself does not independently access or send your Google account information. |
| Purchase information (in-app purchase) | Google Play Billing Library | Used to check the purchase status of a one-time in-app item that unlocks the full route. The transaction is processed by Google Play; we never receive your payment card details. A purchase token is sent to our server only to verify the purchase. |
| Feedback (free-text message) | Text (up to 200 characters), category, and an optional related place name that you choose to enter from the Feedback screen | Stored in Firestore via Firebase Cloud Functions so we can correct and improve in-app content. It is linked to the anonymous ID above, but not to your name or email address. Because this is free text, content you choose to enter could incidentally include information about yourself. Submitting feedback is optional. |
The App uses the following external services, all provided by Google. Please also review each provider's own privacy policy.
The App is not directed at children under 13, and we do not knowingly collect personal information from children under 13 in accordance with the Children's Online Privacy Protection Act (COPPA). As described above, the information the App collects is centered on an anonymous identifier and on-device data that does not identify an individual. If you believe a child under 13 has provided us information, contact us and we will delete it.
Because the App is offered in the United States, state consumer privacy laws may apply, including the California Consumer Privacy Act as amended by the CPRA (CCPA/CPRA), and the laws of Washington, Oregon, Colorado, Nevada and Utah as applicable. The App is designed so that we hold no information that directly identifies you (we process an anonymous identifier only). Within the limits of what we hold, you may have the right to know what personal information we process, to request access to, correction of, or deletion of data linked to your anonymous identifier, and to not be discriminated against for exercising these rights.
We do not sell your personal information and do not share it for cross-context behavioral advertising, and the App contains no advertising or tracking SDKs. We do not use or disclose sensitive personal information beyond what is needed to provide the App's functions. To exercise your rights, contact us at the address below. If you are unsatisfied with our response, you may contact the California Privacy Protection Agency or your state Attorney General.
All communication with external services uses encrypted connections such as HTTPS. Access to Cloud Functions and Firestore is protected by Firebase App Check and security rules.
This policy may be updated to reflect changes in law or in the App's features. Any updated policy takes effect once posted on this page.
