NPSHgraph Privacy Policy
Effective July 20, 2026. This policy explains how NPSHgraph handles information.
Summary
NPSHgraph does not collect data, track you, show ads, require an account, or use a developer-operated backend. The developer does not sell or share personal information from the app.
Information on Your Device
The app may store pump inputs, saved duty cases, comparison choices, and display preferences. These records remain in the app's local container and are not transmitted to the developer.
Device Permissions
The app does not request access to your camera, microphone, location, contacts, health data, or advertising identifier.
Files, Sharing, and Exports
When you select a file or choose a share or export control, Apple system interfaces handle the selection or destination. Processing occurs locally, and the developer does not receive the selected file or export.
Network Access and Third Parties
The app has no developer-operated account service, advertising SDK, analytics SDK, tracking SDK, or crash-reporting SDK. A clearly labeled external reference link may open a website only when you choose it; that website is governed by its own policy.
Retention and Deletion
Local information remains until you delete it with available controls or remove the app. Apple-managed device backups are controlled by your Apple settings.
Product Scope
Results are engineering planning aids. Confirm manufacturer curves, fluid properties, site elevation, piping conditions, and required safety margins.
Children's Privacy
No personal information is knowingly collected from children or any other user because the app transmits no user data to the developer.
Changes
This policy and the App Store privacy disclosure will be updated before a future release changes these practices.
