This privacy policy applies to utility, calculator, engineering, science, and productivity apps published by our company on the App Store, including offline professional tools such as PrintForge Pro, AquaChem Pro, SolarSpec Pro, TimberCalc Pro, StatLab Pro, CableSpec Pro, BrewMaster Pro, GeoSurvey Pro, AcoustiCalc Pro, HeatFlow Pro, PlumbCalc Pro, ConcreteSpec Pro, OpticLab Pro, SoilSpec Pro, and PaintCalc Pro.
We are committed to protecting your privacy and designing apps that work with minimal data handling.
For the apps covered by this policy, calculations and core features run locally on your device. Input values you enter are processed on-device for immediate results. We do not transmit those values to our servers for storage or analysis.
These apps are designed to operate without unnecessary permissions. If an app ever requests an operating-system permission for a specific feature, that permission is used only for that feature on your device and not for unrelated data collection.
Any purchases are processed through Apple's App Store. We do not receive or store your full payment card information.
These apps do not knowingly collect personal information from children under 13.
Because we do not collect user data for the covered apps, there is no server-side personal data profile for us to monetize or analyze. Any information you manually enter into the app for calculation purposes remains under your control on your device unless you choose to export or share it yourself.
We may update this privacy policy from time to time. When we do, we will post the updated version here and revise the "Last updated" date above.
