This Privacy Policy explains what personal data may be processed when you use the Service, the purposes of processing, the legal bases, your rights, and how you can contact us.


1. Data Controller

The data controller responsible for the processing of personal data described in this Privacy Policy is:

We do not operate our own backend servers for collecting personal information. However, the Service uses third-party services provided by Google that may collect or process information as described below.

2. Legal Framework

This Privacy Policy is intended to comply with applicable data protection and digital service regulations, including the General Data Protection Regulation (EU) 2016/679 (“GDPR”), Spanish Organic Law 3/2018 on Personal Data Protection and Digital Rights Guarantee (“LOPDGDD”), and Law 34/2002 on Information Society Services and Electronic Commerce (“LSSI-CE”), where applicable.

Where advertising, analytics, identifiers, SDKs, or similar technologies are used, we also take into account applicable rules related to electronic communications, privacy, consent, and similar technologies, including ePrivacy-related requirements where applicable.

3. Information We Collect Directly

We do not ask users to provide personal information such as name, email address, date of birth, phone number, contacts, photos, messages, payment information, or precise location through our own servers.

The Service stores gameplay progress primarily on your device. The Service also uses Firebase Analytics, Firebase Crashlytics, and Google AdMob to operate, analyze, improve, diagnose, and monetize the app. Google Play Games Services may also be used for sign-in, achievements, leaderboards, and cloud save functionality.

4. Local Data Storage

The Service stores gameplay and preference data locally on your device. This may include:

This local data is not sent to our own servers. If you use Google Play Games sign-in, some gameplay data may be synchronized through Google Play Games cloud save as described below.

You may reset local progress from within the app where this option is available. Resetting local data may not delete data already processed by third-party services such as Google Play Games, Firebase, or Google AdMob.

5. Purposes and Legal Bases of Processing

We process personal data only when there is a valid legal basis. The specific legal basis depends on the feature, service, or processing activity.

You may object to processing based on legitimate interest by contacting us at abcentertainment.games@gmail.com.

11. Network Time Checks

The Service may perform limited network time checks using third-party endpoints to read a trusted server date/time header. This is used to support gameplay systems such as daily rewards, streaks, and time-based restoration logic.

These checks are not used by us to create user profiles or collect personal information through our own servers.

14. International Data Transfers

Third-party service providers such as Google may process information on servers located in different countries, including countries outside the European Economic Area.

Where international transfers occur, they may be carried out using safeguards recognized under applicable data protection law, such as European Commission Standard Contractual Clauses, adequacy decisions, the EU-U.S. Data Privacy Framework where applicable, or other mechanisms implemented by the relevant third-party provider.

We do not sell personal information.

We may share or allow processing of information through third-party service providers only as needed to operate, analyze, secure, improve, or monetize the Service. This includes Google services used for sign-in, cloud save, achievements, leaderboards, analytics, crash reporting, and advertising.

We do not operate a first-party backend server that collects personal information from users.

16. Consent and Withdrawal of Consent

Where processing is based on consent, you may withdraw your consent at any time. Withdrawal of consent does not affect the lawfulness of processing carried out before withdrawal.

Depending on the service, consent and privacy controls may be managed through your Android device settings, Google account settings, Google Play Games settings, advertising personalization settings, or other controls provided by Google.

You may also contact us at abcentertainment.games@gmail.com to exercise your privacy rights or ask questions about consent-related processing.

17. User Choices and Controls

You may have the following choices and controls:

Please note that resetting local app data may not delete information already processed by third-party services such as Google Play Games, Firebase, or AdMob. To manage data held by Google, please use the privacy controls provided by Google.

18. Data Retention

Local gameplay data remains on your device until you reset progress, clear app data, uninstall the app, or the app updates or device system behavior affects local storage.

Data processed by third-party services such as Google Play Games, Firebase, and AdMob is retained according to Google’s own policies, settings, and retention controls.

19. Your Data Protection Rights

Under applicable data protection law, you may have the following rights:

To exercise your rights, contact us at abcentertainment.games@gmail.com. Please indicate which right you wish to exercise and provide enough information for us to respond to your request. We may need to verify your identity before responding.

If your request concerns data processed directly by Google services, such as Google Play Games, Firebase, or AdMob, you may also need to use the privacy controls and request channels provided by Google.

You also have the right to lodge a complaint with a supervisory authority. In Spain, you may contact the Spanish Data Protection Agency (Agencia Española de Protección de Datos, AEPD):

20. Children’s Privacy

The Service is not directed to children under the age of 14 in Spain, or the equivalent minimum age required by applicable law in your jurisdiction.

We do not knowingly collect personal information from children below the applicable minimum age through our own servers. If you believe that a child has provided personal information through the Service, please contact us so that we can take appropriate action.

Where consent is required for the processing of personal data of a child below the applicable minimum age, such consent must be provided or authorized by the holder of parental responsibility, as required by applicable law.

Third-party services used by the Service may process information according to their own policies and account settings.

21. Security

We apply reasonable technical and organizational measures designed to protect the information processed through the Service, taking into account the nature of the data and the risks involved.

The Service stores gameplay data locally on the device and relies on trusted third-party providers such as Google for analytics, crash reporting, advertising, and Play Games features. Access to third-party service dashboards and accounts is restricted to authorized access controlled through those providers.

We aim to minimize the personal data processed directly by us, avoid collecting unnecessary personal information through our own servers, and use third-party services with established security and privacy controls.

However, no method of electronic storage or transmission over the Internet is completely secure. Therefore, we cannot guarantee absolute security.

22. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we make changes, we will update the effective date at the top of this page.

You are advised to review this page periodically for any changes.
