Overview
FlexCalc is a calculator app designed to work without accounts, ads, tracking, or analytics. The app does not collect your calculations, history, constants, settings, or personal information on our servers.
Information stored on your device
FlexCalc may store app settings, calculation history, custom constants, selected language, theme, font, separator preferences, restore-calculation preference, and optional support purchase state locally on your device. This information is used only to make the app work and to restore your preferences when you reopen it.
Information we do not collect

Optional purchases
FlexCalc may offer an optional in-app purchase to support development. Purchases are processed by Apple App Store or Google Play. We do not receive or store your payment card details. The stores may provide purchase status information needed to unlock or restore the support purchase inside the app.
Sharing and feedback
If you use the share feature, the selected text or image is sent only to the app or service you choose from the system share sheet. If you send feedback by email, your email address, subject, message, and any information you include are handled by your email provider and received by us so we can respond.
Third-party services
FlexCalc uses platform services such as Apple App Store, Google Play, and system sharing or email apps when you choose to use those features. Those services are governed by their own privacy policies.
Children's privacy
FlexCalc is a general utility app and does not knowingly collect personal information from children.
