Privacy Policy for Blink
This policy explains what information Blink ("the app") handles. We have kept it short because the app collects very little.
1. Information we collect
M87 Labs does not ask you to create an account and does not collect your name, email address, contacts, location, photos or other personal information. Game progress (scores, wisps, unlocked skins and settings) is stored on your device and is deleted if you uninstall the app. The one exception is the shared high score described in section 4.
2. Advertising (Google AdMob)
The app shows ads using Google AdMob: a banner, occasional full-screen (interstitial) ads between runs, and optional rewarded ads you choose to watch. Buying "Remove Ads" turns off the banner and the full-screen ads; rewarded ads stay available if you choose them. To serve and measure ads, Google may collect and process information from your device such as the advertising ID, IP address, device model, operating system and approximate (coarse) location derived from IP, plus ad interaction data. Where required (for example in the EEA, UK and Switzerland) the app asks for your consent before personalized ads are shown, using Google's User Messaging Platform; you can change your choice at any time from the consent prompt. You can also reset or delete your advertising ID, or opt out of ad personalization, in your device settings (Settings > Google > Ads or Settings > Privacy > Ads).
See how Google uses data: policies.google.com/technologies/partner-sites and Google's privacy policy at policies.google.com/privacy.
3. Analytics and crash reporting (Google Firebase)
Blink uses Google Analytics for Firebase and Firebase Crashlytics to understand how the game is used and to find and fix crashes. This includes app activity (screens viewed, runs started and ended, bosses faced, tutorial progress, settings changes, ads shown and in-app purchase outcomes), crash logs and device technical information (for example app version, OS version and device model), and approximate region derived from IP address. Apart from the anonymous ID described in section 4, Blink does not set a user ID, does not read your location and does not put advertising IDs in its own analytics events. Where consent is required (for example in the EEA and UK), analytics storage stays denied until you consent, and you can change your choice from Settings > PRIVACY OPTIONS. Firebase processes this data for M87 Labs as a service provider; it is retained under the project's Firebase settings and Google's policies.
4. Anonymous ID and the shared high score (Firebase)
Blink creates an anonymous, randomly generated Firebase Authentication ID on each install. There is no account and no sign-in; you do nothing to get this ID. Blink uses it only to submit your best score to one shared, app-wide all-time high score kept in Google Firestore (Firebase). The stored record holds only the top score and a timestamp, with no name or other personal information. The ID is not used for tracking, advertising or building profiles.
5. In-app purchases (Google Play Billing)
Optional purchases (wisp packs and "Remove Ads") are processed entirely by Google Play. M87 Labs never receives your payment card details. We receive only a purchase confirmation (product ID and a purchase token) from Google Play so the app can deliver your item and restore "Remove Ads". Google's handling of payment data is covered by the Google Payments privacy notice.
6. Sharing
M87 Labs does not sell your information. Apart from the Google services described above, no data is shared with third parties. If you use the in-game Share button, a score image is passed to the app you choose; nothing is sent to us.
7. Children
Blink is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us and we will help remove it.
8. Data retention and your choices
Because M87 Labs does not store personal data on its own servers (analytics and crash data, and the shared high score, are held by Google Firebase as described above), there is nothing for us to retain or delete. Uninstalling the app removes all locally stored game data. Data processed by Google is retained under Google's policies.
9. Changes
We may update this policy. The effective date above will change when we do.
