Privacy Policy
Effective date: August 17, 2026
This Privacy Policy applies to Mirror Beam (the "App"), published by Devtrox ("we", "our", or "us").
If you have questions about this Privacy Policy or the App's privacy practices, contact us at:

Information We Collect
The App does not require users to create an account and does not ask users to provide a name, email address, phone number, location, contacts, photos, or other personal information.
The App stores limited game progress data locally on the user's device, such as level progress and ad timing counters. This information is used only to operate the game experience and is not sent to our servers.
Advertising
The App uses Google AdMob to show interstitial and rewarded advertisements. Google AdMob and its partners may collect and process information from the user's device to provide, limit, measure, and improve ads. This may include device identifiers, advertising identifiers, IP address, app interaction data, crash or diagnostic information, and approximate location inferred from IP address, depending on the user's device settings and applicable laws.
Google's use of advertising data is governed by Google's policies:
https://policies.google.com/privacy
Users can manage ad personalization through their device settings and Google account settings where available.
Marketing Measurement
The App uses the Meta (Facebook) SDK to measure the effectiveness of advertising campaigns that promote the App. When a user installs the App after seeing one of our ads, the SDK reports that installation and a small number of anonymous in-game milestones — for example, completing the first level or reaching level 10 — so that we can understand which ads bring players who enjoy the game.
For this purpose, Meta may collect and process the device's advertising identifier, device and app information, IP address, and the app-event data described above. The App does not use Facebook Login, does not read a user's Facebook profile, and does not post anything to Facebook or Instagram on a user's behalf.
Meta's handling of this data is governed by Meta's Data Policy:
https://www.facebook.com/about/privacy
We also promote the App through Google Ads. The analytics data described below is used to measure and improve those campaigns.
Users can limit this collection at any time by enabling "Delete advertising ID" or opting out of ad personalization in Android system settings.
Analytics
The App uses Google Analytics for Firebase to understand how the game is actually played, so that we can improve it and judge whether our advertising reaches players who enjoy it.
The App reports anonymous in-game events: the first time each level is completed, reaching certain level milestones, choosing to watch a rewarded advertisement in exchange for a hint, and the fact that an advertisement was displayed together with the estimated revenue that impression earned. The App does not report anything a user types, and it assigns no account or personal identifier of its own.
For this purpose, Google may collect and process an app instance identifier, the device's advertising identifier, device and app information, IP address and the approximate country derived from it, and the event data described above.
Google's handling of this data is governed by Google's Privacy Policy:
https://policies.google.com/privacy
Users can limit this collection at any time by enabling "Delete advertising ID" or opting out of ad personalization in Android system settings.
How We Use Information
We use information only for the following purposes:
- To run the App and save game progress locally on the device.
- To show and manage ads through Google AdMob.
- To understand how the game is played so that we can improve it.
- To measure the performance of our advertising campaigns through Meta and Google Ads.
- To maintain app functionality, security, and performance.
Sharing of Information
We do not sell personal information.
We do not share locally stored game progress with third parties.
Advertising data may be collected or processed by Google AdMob and its advertising partners, campaign measurement data by Meta, and analytics data by Google Analytics for Firebase, as described above. We do not control all data processing performed by Google, Meta, or their partners.
Data Retention and Deletion
Local game progress remains on the user's device until the user clears the App's data or uninstalls the App.
The App does not provide user accounts, so there is no account data to delete. To delete local App data, users can uninstall the App or clear its storage from Android system settings.
Analytics event data collected through Google Analytics for Firebase is retained for up to 2 months and is then deleted automatically.
Advertising data handled by Google, and campaign measurement data handled by Meta, are retained according to those companies' own policies.
Security
We use reasonable measures to limit the App's data handling to what is necessary for gameplay and advertising. No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.
Children's Privacy
The App does not knowingly ask children to provide personal information.
The App is a game that anyone can download and play. The App does not ask users, including children, to provide personal information.
If a parent or guardian believes that a child has provided personal information through the App, they may contact us at support@dev-trox.com and we will take reasonable steps to address the request.
Third-Party Services
The App uses the following third-party services:
- Google AdMob: advertising and ad measurement
- Meta Platforms (Facebook SDK): advertising campaign measurement and attribution
- Google Analytics for Firebase: product analytics and advertising campaign measurement
