Privacy Policy

Last Updated: October 9, 2026

Thank you for using this application (the "App"). We value your privacy and are committed to protecting any data generated during your use of the App. This Privacy Policy explains what information may be collected, how it is used, shared, and your rights regarding this information.

1. Information We Collect

To ensure proper functionality and improve user experience, the App may collect the following information:

• Device Information: device model, operating system version, language settings, and other technical information.
• Usage Data and Logs: app usage patterns, actions taken within the app, crash logs, performance statistics, analytics events, and interaction data collected through Firebase Analytics.
• Advertising Data: When the App uses Google Mobile Ads SDK (AdMob), certain information may be collected automatically, including IP address, advertising identifiers, device identifiers, ad interactions, and diagnostic information. This information may be used for ad delivery, advertising measurement, fraud prevention, and related purposes.

2. How We Use Information

The information collected is used to:

• Ensure the App functions correctly
• Analyze usage, measure app performance, understand user interactions, and optimize the user experience through Firebase Analytics
• Resolve technical issues and provide necessary support
• Comply with legal obligations and protect the App's legitimate interests
• Display advertisements, measure advertising performance, prevent fraudulent activity, and improve the relevance and effectiveness of ads through Google Mobile Ads SDK (AdMob).

3. Analytics, Advertising, and Third-Party Services

• We use Firebase Analytics, a service provided by Google, to understand how users interact with the App, measure app performance, analyze feature usage, and improve the overall user experience.
• Firebase Analytics may collect information such as app usage data, analytics events, device information, and certain identifiers or user properties. Some data may be collected automatically by the Firebase Analytics SDK.
• We use Google Mobile Ads SDK (AdMob), a service provided by Google, to display advertisements in the App. In connection with providing advertising services, Google may collect and process certain information automatically, including IP address, advertising identifiers, device identifiers, ad interactions, and diagnostic information. This information may be used for ad delivery, ad personalization where permitted, advertising measurement, analytics, and fraud prevention.
• Depending on applicable laws, your location, and your device or advertising privacy settings, advertisements may be personalized or non-personalized. Limiting ad tracking or changing your device's advertising settings may affect ad personalization, but does not necessarily prevent all data collection or processing required to provide advertising services.

• We do not sell users' personal information. Information may also be disclosed when required by law or when reasonably necessary to protect our legal rights, with disclosure limited to what is necessary for the relevant purpose.

5. Data Security

We take reasonable technical and administrative measures to protect the information collected. However, no system is completely secure, and users should understand the potential risks when using the App.
