2. INFORMATION WE PROCESS
2.1 Technical Data Processed on Device
To ensure the stable operation of the App, the App may locally utilise certain technical configurations. This data is processed strictly on your device and is not transmitted to our servers or to any third-party analytics / advertising networks:
• Device Information — device model, manufacturer, operating system version, system language, time zone, and screen resolution required for proper interface rendering.
• App Activity / App Interactions — internal technical states, session duration, and features interacted with, used to maintain application progress locally on the device.
2.2 Information You Provide
The App does not require account registration, login, or any personal profiling. We do not collect or request your name, email address, phone number, password, or payment information.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
3. HOW WE USE INFORMATION
We use the local technical information strictly to:
• Operate, maintain, and improve the App's performance.
• Ensure the application runs correctly on your specific device model.
• Detect, prevent, and address local technical issues and bugs.
We do not sell, rent, or share any user data with third parties.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
4. THIRD-PARTY SERVICES & SDKs
The App does not integrate any third-party advertising SDKs, marketing analytics trackers, or push notification networks (such as Firebase, AppsFlyer, OneSignal, or Facebook). No data is shared with or transmitted to external advertising or data-broker companies.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

5. LEGAL BASIS FOR PROCESSING (GDPR)
Since the App processes technical data locally on your device to provide the requested service (the core application function), the processing is based on the execution of core functionality and our legitimate interest in providing a functional and secure application.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
6. DATA RETENTION
Any progress data or local technical configurations remain on your device and are deleted automatically if you clear the application cache or uninstall the App.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
7. YOUR RIGHTS
Depending on your jurisdiction (including the EEA, UK, and various US states), you have rights regarding data protection. Since we do not transmit, store, or possess your personal data on any servers, we cannot provide copies of or erase data that we do not hold. You can fully control your data by managing the App settings or uninstalling the application.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
8. CHILDREN'S PRIVACY
The App is designed for a general audience, including children (category 3+). We comply strictly with the Google Play Families Policy, COPPA (Children's Online Privacy Protection Act) in the United States, and the GDPR provisions regarding children in the EEA / UK.
Because the App does not include any third-party tracking SDKs or behavioral advertising integrations, we do not knowingly collect, transmit, or share personal data from children. If you have any questions regarding our compliance, please contact us at support@colleranholdingslimited.com.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
9. DATA SECURITY
The App operates locally on your device. We encourage users to keep their operating systems up to date with standard security patches to protect local application data from unauthorised device-level access.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
10. INTERNATIONAL DATA TRANSFERS
Because the App does not collect or transmit data over the internet to external cloud storage or third-party servers, your data does not undergo international transfers.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
11. CHANGES TO THIS PRIVACY POLICY
We may update this Privacy Policy from time to time to reflect changes in our local practices or for legal and regulatory reasons. We will notify you of any changes by updating the "Last Updated" date at the top of this policy.
