Privacy Policy

The Grid Master
Last updated: August 15, 2026
In short: The Grid Master does not require an account and does not ask you for any personal information. Your progress is stored on your device. The App displays third-party ads and uses analytics; those partners may process limited technical data as described below.

1. Who we are

The Grid Master (the “App”) is a puzzle game published by Blue Arvor (“we”, “us”, the “Developer”). This Privacy Policy explains what information the App and its service providers handle, and the choices you have.

2. Information the App handles

The App does not ask you to create an account and does not collect your name, email address, contacts, photos, precise location, microphone or camera. The information involved is limited to:

3. Advertising

The App displays third-party advertisements (full-screen interstitial ads shown between games). To serve, cap and measure these ads, we use Google AdMob (and, where applicable, its mediation partners). These partners may collect and process:

Ads may be personalized or non-personalized depending on your consent and settings. For details on how Google uses this data, see How Google uses information from sites or apps that use its services and the AdMob data disclosure.

4. Analytics

The App uses Google Analytics for Firebase to understand aggregate app usage — for example which grid sizes are played and how often a game is finished — so we can improve the App. Firebase collects a randomly generated app-instance identifier together with device and event information; it does not receive your name or email address, and we use the results in aggregate, not to identify you personally. See Firebase’s privacy and security information and Google’s Privacy Policy.

5. Notifications

The App does not send push notifications and does not create a push token.

6. Your choices & advertising identifiers

7. Legal bases (EEA/UK)

Where the GDPR applies, we rely on your consent for personalized advertising and non-essential analytics, and on our legitimate interests for providing, securing and improving the App and for showing non-personalized ads.

8. Data sharing

We do not sell your personal information. Technical and advertising data is processed by the service providers named above solely to run the features described in this policy. Under laws such as the CCPA/CPRA, certain ad-related data sharing may be considered “sharing” for targeted advertising; you may opt out via the controls in section 6.

9. Children

The Grid Master is suitable for a general audience. We do not knowingly collect personal information from children. Where the App is made available to children, advertising is configured to serve only non-personalized ads in line with applicable requirements (e.g. Google Families policies and Apple’s Kids guidelines). If you believe a child has provided personal data, please contact us and we will delete it.

10. Data retention & security

On-device game data remains until you delete it or uninstall the App. Data handled by our service providers is retained according to their own policies. We use industry-standard measures to protect information, but no method of transmission or storage is 100% secure.

11. International transfers

Our service providers may process data in countries other than yours. Where required, such transfers are covered by appropriate safeguards (such as the European Commission’s Standard Contractual Clauses).

12. Your rights

Depending on where you live, you may have the right to access, correct, delete, or restrict the processing of your personal data, to object to processing, and to withdraw consent. To exercise these rights, contact us using the details below.

13. Third-party stores

The App is distributed through Google Play and the Apple App Store, which may collect data as described in their own policies. See Google’s Privacy Policy and Apple’s Privacy Policy.

14. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected here with a revised “Last updated” date.
