Information we collect
LubeCalc Pro is designed with privacy in mind. We do not collect personal data, location data, app-usage analytics, advertising identifiers, or behavioral data, and the app does not require an account.
Third-party purchase services
RevenueCat is used to manage in-app purchases and purchase validation. RevenueCat processes anonymous transaction information supplied by Apple or Google to verify purchase status. Apple App Store and Google Play may separately collect information under their own privacy policies. Spartan does not receive payment-card details.
Data stored on your device
Calculation inputs, saved projects, reports, and app preferences are stored locally on your device and are not transmitted to Spartan servers. Deleting the app removes locally stored app data unless it is restored through a device-backup service.
How information is used
Anonymous purchase-validation information is used only to verify purchase status, unlock purchased features, and manage the free-trial period. It is not used for advertising, marketing, or profiling.
Security
Because Spartan does not collect or store personal app data on its servers, server-side exposure is limited. Data stored locally is protected by the security features available on your device, including passcodes, biometrics, and device encryption.
Children's privacy
LubeCalc Pro is a professional engineering tool and is not directed to children under 13. We do not knowingly collect information from children.
Your choices and rights
You can remove locally stored app data by deleting the app, manage purchases through the applicable app store, and review or exercise rights directly with third-party purchase services. Spartan does not sell personal information as defined by the California Consumer Privacy Act.
International users
LubeCalc Pro is operated from the United States. Minimal purchase-validation processing by third parties may occur on servers located in the United States or other jurisdictions.
