Drywall Stud & Ceiling Calc Privacy Policy
Privacy Policy
This privacy policy governs your use of the mobile software application Drywall Stud & Ceiling Calc ("Application"), distributed under the publisher profile ZanshinLab as an offline utility tool with advertising monetization.
1. Core Architecture & Data Privacy (Zero Collection)
User-Provided Information: The Application does not require or collect any user registration, account creation, or personal data submission to function. All calculation modules are fully operational immediately upon installation.
100% Offline Local Storage: All dimensional inputs, material takeoffs, framing parameters, and logged estimations remain completely local. The Application processes and records data strictly within your device's internal storage via JavaScript localStorage. This data never leaves your device and is never transmitted to external servers or third parties.
2. Advertising & Monetization (Google AdMob Disclosure)
Third-Party Integration Notice:
This Application displays non-intrusive interstitial advertisements served via the Google AdMob network. Because the Application incorporates the Google AdMob SDK for monetization, certain device data is accessed and collected automatically to serve, optimize, and measure ad performance.
Information automatically accessed by Google AdMob includes:
- The mobile device's Android Advertising ID (AAID).
- The IP address of the device (utilized solely by the network for approximate geographical targeting and ad fraud protection).
- Hardware specifications (device model, manufacturer, operating system version, and screen scale factors).
- Anonymized interaction metrics (ad impressions, clicks, and systemic transition timelines).
3. Third-Party Legal Links
We have no operational access to or control over the data processed natively by third-party ad networks. Please reference Google's official documentation to understand how they manage and protect data:
4. Children's Privacy Compliance
The Application functions as a technical math calculator and does not target children under the age of 13. Since no personal data is ever collected, logged, or transferred by the developer, no parental privacy boundaries are breached.
