Privacy Policy
This Privacy Policy applies to the Unit Hollow mobile application (the "Application") created and operated by holowapps (the "Service Provider").
1. Information Collection and Use
The core functionality of the Application (all calculations and unit conversions) operates locally on your device and does not require an account or personal information.
However, the Application uses third-party services to display advertisements. These third-party services may collect certain device identifiers and operational data to serve and personalize ads, prevent fraud, and monitor performance.
2. Third-Party Services and Advertising
To support the ongoing maintenance and development of the Application, we use Google AdMob to display ads.
Google AdMob may collect and process information such as:
- Device identifiers (such as Google Advertising ID / AAID)
- IP address and general location (country/city level)
- App interaction and ad performance data (impressions, clicks, diagnostics)
This data is collected directly by Google in accordance with their privacy practices. For more information on how Google collects and uses your data, please visit:
3. Cookies and Tracking Technologies
The Application itself does not use cookies. However, third-party advertising partners like Google AdMob may utilize SDKs and identifier technologies within their ad delivery frameworks to deliver relevant ads and detect invalid traffic.
4. Children’s Privacy
The Application is not directed to children under the age of 13. We do not knowingly collect personally identifiable information from children. If you are a parent or guardian and believe that your child has provided personal information through third-party services, please contact us so that we can take necessary actions.
5. Data Retention and Deletion
The Service Provider does not store or retain your personal data on proprietary servers. Any data processed by third-party ad networks (such as Google AdMob) is managed according to their respective data retention and deletion policies. Users can manage or reset their Advertising ID at any time through their Android device settings (Settings > Google > Ads).
6. Security
We prioritize user privacy and application security. All unit conversion calculations are performed locally on your device, and network access is limited strictly to delivering advertisements via Google's secure APIs.
7. Changes to This Privacy Policy
The Service Provider may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. You are advised to review this policy periodically for any changes.
Effective Date: 2026-08-16
