While Blockudoku Freak does not require user accounts or direct input of personally identifiable information such as names or email addresses, certain technical and usage data are collected automatically through third-party services integrated into the app. This data is essential for the app's functionality, performance, and the display of advertisements.
All game progress, settings, and preferences not related to third-party services are stored locally on your device and remain under your control.
We use Google AdMob to display advertisements within Blockudoku Freak. When you use our app, AdMob automatically collects and processes certain data from your device. This data collection is integral to providing the advertising service and helping us generate revenue to keep the app free.
As the app developer, we are the data controller responsible for the integration of AdMob and for determining the purposes of this data processing within our app. Google acts as a data processor (or in some contexts, a co-controller) on our behalf for these services. The processing of this data by Google is also subject to Google's privacy policy.
Data that AdMob may collect includes:
Device information (device type, operating system, screen size)
Advertising identifiers (such as Google Advertising ID)
IP address
App usage information and interactions
Location data (if location services are enabled on your device)
Your choices regarding AdMob: You can opt out of personalized advertising through your device's advertising settings:
Android: Settings > Google > Ads > Opt out of Ads Personalization
For more information about Google's data practices, please review:
Google Privacy Policy
Google AdMob Data Usage
Our app offers the ability to purchase ad removal through the Google Play Store or Apple App Store. These transactions are processed entirely by the respective app stores and are subject to their privacy policies and terms of service.
While we do not receive or process sensitive payment information (like credit card details), we do receive information regarding your purchase history (e.g., ad removal purchase status) to deliver the in-app content and for analytical purposes.
For users in the European Union, the legal basis for data processing related to AdMob may include:
Consent: For personalized advertising, where required by law, we (or Google on our behalf) will obtain your consent through a Consent Management Platform before displaying personalized ads.
Legitimate Interest: We have a legitimate interest in providing our app for free by displaying advertisements, which requires AdMob's data processing for:
Ad delivery and measurement
Analytics and performance monitoring
Fraud prevention and security
Non-personalized advertising
As the Data Controller for Blockudoku Freak, we are committed to facilitating your GDPR rights. While much of the data processing through our app is handled by Google AdMob, you can contact us directly to exercise your rights, and we will collaborate with Google and other relevant parties to address your request.
Your rights include:
Right of Access: Request access to the personal data processed about you.
Right to Rectification: Request correction of inaccurate personal data.
Right to Erasure ('Right to be Forgotten'): Request the deletion of your personal data.
Right to Restriction of Processing: Request limitations on the processing of your personal data.
Right to Object: Object to the processing of your personal data, including personalized advertising (which you can also control through your device settings).
Right to Data Portability: Request a copy of your personal data in a machine-readable format.
Right to Withdraw Consent: Where processing is based on consent, you have the right to withdraw your consent at any time.
Right to Complain: Lodge a complaint with your local data protection authority.
To exercise these rights, please contact us at: engineeryourconvenience@proton.me
Our app: Game progress and settings stored locally on your device remain until you delete the app or clear its data.
AdMob: Data retention periods are governed by Google's data retention policies. Generally, Google retains advertising data for up to 26 months, though some data may be retained longer for legitimate business purposes.
Purchase history: Information about in-app purchases (ad removal) is retained as long as necessary to provide the purchased content and for accounting/legal purposes.
