Privacy Policy
HS and College Calculator · Last updated July 1, 2026
HS & College Calculator is designed to be local-first and private. The app works entirely on your device, requires no account, and does not transmit your calculations or personal information to any server. This policy explains what that means in practice.
Information We Collect
HS & College Calculator does not collect personal information. No name, email address, device identifier, or usage data is gathered, transmitted, or stored outside your device.
All calculations, history, graphing expressions, and formula notes are saved locally in your app's private storage on your device. This data never leaves your device through the app.
How We Use Information
Because we do not collect information, there is nothing to use, sell, share, or process. The app's features — including calculator history, unit conversion, graphing, and step-by-step solutions — operate entirely on-device without any outbound data transfer.
Product And Technical Data
The app does not integrate analytics SDKs, crash-reporting services, advertising networks, or any third-party data processors. No diagnostic or performance data is automatically collected or transmitted.
Standard Apple iOS system diagnostics may be reported to Apple separately under Apple's own privacy policy if you have opted in to share diagnostics with Apple developers. We do not receive or access that data.
How We Share Information
We do not share any information with third parties because we do not collect any. There are no advertising partners, analytics providers, data brokers, or other recipients of data originating from this app.
Data Retention
Your calculation history, saved expressions, and preferences are stored locally on your device and are retained until you delete them within the app or uninstall the app. We have no copies of this data and cannot retrieve or restore it on your behalf.
Your Choices
You are in full control of your data. You can clear your calculation history at any time from within the app. Uninstalling the app permanently removes all locally stored data. Because no data is sent to us, there is no remote data to request, export, or delete.
Children's Privacy
HS & College Calculator is intended for high school and college students. The app does not collect any personal information from users of any age, including children under 13. Because no data is collected or transmitted, the app is safe for use by minors in educational settings.
