For more information about Google's privacy practices, please review Google's privacy information and advertising policies.
If a future version of Excel Master removes advertising, this section will be updated accordingly.

Analytics services do not give us access to information that you have not provided or that the service is not designed to collect.

This information may include:
Device model

This information is used to identify bugs, improve stability, and provide a better experience.

Depending on the version of the App, these services may include services provided by:
Google Play Services
Google AdMob
Firebase or other analytics services
Firebase Crashlytics or other diagnostic services
Other technical service providers required to operate the App
These third-party providers may process information according to their own privacy policies.
We recommend that users review the privacy policies of applicable third-party service providers.
We remain responsible for accurately declaring relevant data practices in Google Play's Data Safety section.
8. How We Use Information
Information processed in connection with Excel Master may be used for the following purposes:
Providing the App's functionality
Providing Excel formula information and educational content
Providing interactive quizzes
Saving user preferences and favorites
Maintaining app functionality
Improving application performance
Detecting and fixing technical problems
Preventing fraud, abuse, and security threats
Understanding general application usage
Showing advertisements, where applicable
Measuring advertising performance, where applicable
Improving the App and its features
Complying with applicable legal obligations
We do not use personal information for purposes that are incompatible with the purposes disclosed in this Privacy Policy.
9. Data Sharing
We do not sell your personal information.
Information may be processed or shared with third-party service providers only when reasonably necessary to operate, maintain, secure, analyze, or monetize the App.
For example, advertising, analytics, crash-reporting, hosting, or other technical providers may process information through their SDKs or services.
We may also disclose information where required by applicable law, legal process, court order, or a valid governmental request.
10. Data Security
We take reasonable measures to protect information processed through the App.
Where information is transmitted by third-party services, those services may use security technologies such as encryption in transit.
However, no method of electronic transmission or electronic storage can be guaranteed to be completely secure.
We therefore cannot guarantee absolute security of information processed through the App.
Google Play's User Data requirements also require developers to handle personal and sensitive data securely, including using modern cryptography such as HTTPS where appropriate.
11. Data Retention
We retain information only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required by law.
Information stored locally by the App generally remains on your device until you:
Delete it through available App controls;
Clear the App's data through Android settings; or
Uninstall the App.
Information processed by third-party services may be retained according to their respective policies and retention practices.
12. Data Deletion
Excel Master does not require users to create an account for its core functionality.
Therefore, if you are using a version of Excel Master that does not provide an account system, there may be no server-side user account associated with you.
You may remove locally stored App data by using the Android device's application settings or by uninstalling the App.
If a future version of Excel Master introduces user accounts or server-side personal information, we will provide an appropriate account and data deletion mechanism and update this Privacy Policy accordingly.
Google Play requires apps offering account creation to provide users with a clear method to request account deletion and associated data deletion.
13. Children's Privacy
Excel Master is an educational application and may be useful to students and learners.
The App does not knowingly request or collect sensitive personal information from children for purposes unrelated to the App's functionality.
If you believe that a child has provided personal information to us in a manner that is not appropriate, please contact us using the contact information provided below.
If the App is distributed to children or is specifically directed toward children, additional Google Play Families requirements may apply. We will comply with applicable requirements for the intended audience of the App.
14. Permissions
Excel Master only requests permissions that are necessary for the functionality of the App or for services used by the App.
Depending on the version of the App and the features enabled, permissions or access may vary.
If a permission is not required for a particular feature, the App will not intentionally use that permission for an unrelated purpose.
Users can review or change application permissions through Android device settings where Android provides such controls.
15. Offline and Local Features
Many educational features of Excel Master may work without requiring users to create an account.
Formula information, quiz content, favorites, history, settings, and similar functionality may be stored locally on the device depending on the implementation of the App.
Some services, such as advertisements, analytics, updates, or other online functionality, may require an internet connection.
16. Internet Connection
Certain features of Excel Master may require an internet connection.
If the App connects to third-party services, information may be transmitted to those services as described in this Privacy Policy.
You are responsible for any data charges imposed by your mobile network or internet service provider.
17. Links to Other Websites or Services
The App may contain links or references to external websites or third-party services.
We are not responsible for the privacy practices, content, security, or policies of third-party websites or services.
We encourage users to review the privacy policies of external services before providing personal information.
18. Changes to This Privacy Policy
We may update this Privacy Policy from time to time.
When changes are made, we will update the "Last Updated" date at the top of this Privacy Policy.
If significant changes are made to the way the App handles personal information, we may provide additional notice through the App or other appropriate means.
Your continued use of Excel Master after an updated Privacy Policy becomes effective means that you acknowledge the updated policy.
19. Your Privacy Choices
Depending on your device, Android version, region, and the services used by the App, you may have choices relating to:
Advertising personalization
Device permissions
Analytics-related settings
Local application data
Internet access
App installation and removal
You can manage applicable Android permissions through your device settings.
Where applicable, Google also provides controls for managing advertising preferences.
20. No Sale of Personal Information
We do not sell users' personal information.
We do not knowingly sell personal or sensitive user data to third parties.
Third-party advertising or analytics services may independently process information according to their own terms and privacy policies.
21. Legal Compliance
We may process or disclose information when reasonably necessary to:
Comply with applicable laws and regulations
Respond to valid legal processes
