Privacy Policy
This policy explains the data practices of the app and the third-party services used for advertising and subscriptions.
Developer and contact
The app is provided by Nova Soft. Dev. For privacy questions or deletion requests, contact nova.softwaredevelop@gmail.com.
3D model files and calculations
Files you open, models you process, model measurements, conversion results and cost-calculation inputs are processed on your device for the requested app functions. The developer does not upload these files or inputs to its own server. Files are saved to device storage only when you choose to save or export them.
Advertising — Google AdMob
The free version uses Google Mobile Ads (AdMob) to display ads. The Google Mobile Ads SDK may automatically collect and share:
- IP address, which may be used to estimate approximate location;
- app interactions such as app launches, taps and ad/video views;
- diagnostic and performance information, including launch time, hangs and energy use; and
- device and account identifiers, including the Android Advertising ID and App Set ID where available.
Google uses this information for advertising, analytics, fraud prevention and security. Where required by law, the app asks for consent through Google’s User Messaging Platform before requesting ads. You can revisit or withdraw eligible advertising choices from Subscription → Ad privacy choices inside the app and can reset or delete the advertising ID in Android settings.
Learn more in Google’s Privacy Policy and Advertising Policies.
Subscriptions — RevenueCat and Google Play Billing
The app uses Google Play Billing and RevenueCat to offer and validate Pro subscriptions. These services process purchase history, product and subscription status, purchase tokens, an app-specific user identifier, locale/currency and related transaction information. This processing is required to complete purchases, restore access, prevent fraud, provide app functionality and measure subscription performance. The developer does not receive your full payment-card details.
See the RevenueCat Privacy Policy and Google Privacy Policy.
Legal basis, retention and security
Consent is used where required for personalised advertising. Contract performance and legitimate interests are used to provide app functions, verify subscriptions, secure the services and prevent fraud. Third-party providers retain data according to their own policies and legal obligations. Data transmitted by AdMob and RevenueCat is encrypted in transit. No method of transmission or storage is completely secure.
Your choices and rights
Depending on your location, you may request access, correction or deletion, object to or restrict processing, or withdraw consent. Use the in-app ad privacy entry point for advertising choices. For developer-held support records or help with a RevenueCat customer-data deletion request, follow the steps on our Data Deletion Request page. You may also manage or cancel subscriptions in Google Play.
Children
The app is not directed to children under 13 and the developer does not knowingly collect personal information directly from children. If you believe a child has provided personal information, contact us so appropriate action can be taken.
International processing and changes
Google and RevenueCat may process information in countries other than your own using safeguards described in their policies. This policy may be updated when app features, SDKs or legal requirements change. The current version will remain available at this URL with its effective date.
