Gridline ("the App", "we", "us") is a mobile block puzzle game. This Privacy Policy explains what data may be collected or processed when you use the App, how that data is used, and how it is protected.
The App does not require users to create an account and does not ask users to provide direct personal information such as name, email address, phone number, or account credentials.
However, the App uses third-party services, including Google AdMob, Google User Messaging Platform, Firebase Analytics, and Firebase Crashlytics. These services may automatically collect or process certain data as described below.
The following data may be collected automatically through third-party services used by the App:
| Data | Purpose | Service |
|---|---|---|
| Advertising ID and related ad identifiers | Serve rewarded ads, prevent fraud, measure ad performance, and support ad personalization where allowed by user consent and applicable law | Google AdMob |
| Consent status and advertising preferences | Manage privacy choices and ad personalization preferences | Google User Messaging Platform (UMP) |
| Firebase Installation ID (FID) | Identify an app installation for analytics, diagnostics, and service operation. This identifier is not used by us to identify a person directly. | Firebase |
| App usage events | Understand how the game is played, improve gameplay balance, improve user experience, and measure app performance | Firebase Analytics |
| Crash logs, stack traces, diagnostic information, and custom diagnostic keys | Find and fix bugs, crashes, and stability problems | Firebase Crashlytics |
| Device and app information, such as device model, operating system version, app version, language, and country or region | Analytics, diagnostics, crash reporting, fraud prevention, and app improvement | Firebase and Google services |
| Approximate location, such as country or region inferred from IP address or device signals | Analytics, advertising, fraud prevention, legal compliance, and service localization | Google services |
The App may log the following gameplay and app events to Firebase Analytics:
| Event | Parameters |
|---|---|
game_start | Game mode, theme |
game_over | Game mode, score, duration, theme, cause |
duel_start | Bot preset, difficulty, theme |
duel_result | Result (win/loss/draw), player and bot scores, preset, turns, duration |
boost_used | Boost type (swap/erase/reshuffle/freeze), game mode |
revive_used | Game mode |
mission_completed | Mission type, game mode |
mission_timeout | Mission type, game mode |
theme_changed | New theme |
screen_opened | Screen name |
| Ad lifecycle events | ad_loaded, ad_shown, ad_rewarded, ad_dismissed, ad_load_failed, ad_show_failed |
Firebase Crashlytics may collect crash logs, stack traces, diagnostic information, and custom diagnostic keys such as game_mode, bot_preset, and bot_difficulty. This data is used to identify and fix bugs. Crashlytics collection is disabled in debug builds.
The App does not directly ask users to provide:
Please note that third-party services used by the App may process identifiers, diagnostics, app activity, approximate location, and device information as described in this Privacy Policy.
Your game progress, scores, settings, and local preferences are stored on your device. This local game data is not sent to our own servers. Uninstalling the App or clearing app data will delete this local data from your device.
The App uses Google AdMob to display rewarded video ads. Rewarded ads are optional and may be shown when you choose to use an in-game reward, such as a second chance or revive feature.
Google AdMob may collect or process data such as Advertising ID, device information, approximate location, ad interactions, and other signals to serve ads, measure ad performance, prevent fraud, and comply with applicable law.
The App uses Google's User Messaging Platform (UMP) consent framework to present privacy and ad personalization choices where required by applicable regulations, such as GDPR and ePrivacy rules. You may also manage ad personalization through your device settings:
For more information, see the Google Privacy Policy.
We use Firebase Analytics to understand how the App is used, which game modes are played, how features perform, and how we can improve the App.
We use Firebase Crashlytics to collect crash reports and diagnostic information so we can find and fix bugs and improve stability.
Firebase may assign a Firebase Installation ID (FID) to each app installation. The FID is a randomly generated identifier used for app analytics, diagnostics, and service operation. It is not used by us to directly identify a person. The FID may be reset if the user clears app data or reinstalls the App.
Google services may use your IP address or device signals to infer approximate location, such as country or region. We do not collect precise GPS location.
For more information, see the Firebase Privacy and Security documentation.
We do not sell user data.
We may share or make data available to the third-party services used by the App, including Google AdMob, Google User Messaging Platform, Firebase Analytics, and Firebase Crashlytics. These services process data on our behalf or as independent service providers according to their own privacy policies and terms.
No data is sent to our own servers because we do not operate a separate backend server or user database for the App.
Data transmitted from the App to Google AdMob and Firebase services is encrypted in transit using HTTPS/TLS. Google and Firebase apply security measures to protect data processed by their services.
Because no method of transmission or storage is completely secure, we cannot guarantee absolute security. We use reputable third-party services and limit the data collected by the App to what is needed for advertising, analytics, diagnostics, consent management, fraud prevention, and app improvement.
The App is not directed to children under 13 and is not intended for use by children under 13. We do not knowingly ask children to provide personal information.
If you believe that a child has provided personal information through the App, please contact us. We will review the request and take appropriate steps where possible.
Local game progress, scores, and settings remain on your device until you delete the App or clear app data.
Data processed by Google AdMob, Firebase Analytics, and Firebase Crashlytics is retained according to Google's and Firebase's retention policies and settings. Analytics data may be retained according to the configured Firebase retention period. Crash reports are retained according to Firebase Crashlytics retention rules.
Because the App does not require user accounts and we do not operate our own user database, we may not be able to identify or delete a specific user's analytics or advertising records directly. You can reset or limit your Advertising ID in Android settings, clear app data, uninstall the App, or contact us with a deletion request. We will review deletion requests and take reasonable steps where possible.
The App uses the following third-party services:
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the App after changes means that the updated policy applies to your use of the App.
