Chuanming built the Fraction Calc + app (the "App") as a Freemium app. This SERVICE is provided by us at no cost for the basic features, with an optional one-time purchase for Pro features, and is intended for use "as is".
Our privacy philosophy is simple: What happens on your device, stays on your device.
We DO NOT collect, store, share, or transmit any personal data, usage data, or analytics. The App operates 100% offline. All your measurements, cut lists, and custom cheat sheets are saved locally on your device's internal storage. We do not have access to your data.
The App DOES NOT use any third-party backend servers, analytics tools, or advertising frameworks. There are zero ads and zero tracking scripts embedded in the App.
If you choose to unlock the Pro features via an In-App Purchase, the transaction is processed securely and directly by Apple (App Store) / Google (Google Play). We do not collect or have access to your credit card information, billing address, or underlying financial details.
We may update our Privacy Policy from time to time. However, since we do not collect any data, future updates will primarily reflect administrative changes. We will notify you of any changes by updating the "Last updated" date at the top of this page.
If you have any questions or suggestions about our Privacy Policy, do not hesitate to contact us at: hualuojian@foxmail.com
