Overview
CalcPure ("the App") is a calculator application developed by Kohei Omori ("we", "us", "our"). We are committed to protecting your privacy. This Privacy Policy explains what information the App collects, how it is used, and your rights.
Information We Do NOT Collect
CalcPure is designed with privacy as a core principle:
No personal data collection — We do not collect your name, email address, phone number, or any other personal information.
No analytics or tracking — We do not use any analytics SDKs, tracking pixels, or similar technologies.
No advertising — The App contains no ads and no ad-related tracking.
No location data — We do not access or collect your location.
No camera or microphone access — The App does not request or use these permissions.
No third-party data sharing — We do not share, sell, or transfer any data to third parties for advertising or marketing purposes.
Data Stored on Your Device
The App stores the following data locally on your device only using AsyncStorage:
Calculation history — Your recent calculations (up to 100 entries)
Calculator state — Current calculation in progress (for state persistence)
This data:
Never leaves your device
Is not transmitted to any server
Is not backed up to our servers
Can be deleted by uninstalling the App or clearing the App's data
Purchases
CalcPure is a one-time paid app. It contains no in-app purchases and no subscriptions. All features are unlocked from first launch. We do not use any third-party purchase or analytics service.
Payment processing is handled entirely by Apple's App Store. We never receive or store your payment information (credit card numbers, billing address, etc.).
Children's Privacy
The App does not knowingly collect any personal information from children under the age of 13. Since we do not collect personal data from any users, this applies equally to all age groups.
