Welcome to Magnet Weight Calculator (the "App"), provided by Klas Lu. The App is a utility tool that calculates magnet weight based on dimensions, shape, and material density.
We respect your privacy. This Privacy Policy explains how the App handles information. In short: the App does not collect, upload, or sell your personal data. All calculations are performed locally on your device.
The App does not require account registration and does not collect your name, email address, phone number, location, contacts, photos, or other personally identifiable information.
The App only stores the following data locally on your device to remember your preferences:
Dimension values you enter are used only for the current weight calculation. They are not uploaded to any server and are not stored by the App for other purposes.
Locally stored material parameters are used solely to:
We do not use this information for advertising, user profiling, behavioral analytics, or any purpose unrelated to the App's core functionality.
All calculations are performed locally on your iPhone or iPad. Material parameters are saved on your device using iOS local storage (UserDefaults).
The App does not connect to the internet to transmit your input or usage data. If you uninstall the App, the related local data will be removed along with the App (unless retained by an iOS system backup).
The App does not integrate third-party analytics, advertising, or social networking SDKs. We do not share your information with any third party.
When you download, update, or make purchases through the App Store, related information is handled by Apple in accordance with Apple's Privacy Policy. That process is outside the control of this App.
The App is intended for general users and does not knowingly collect personal information from children under 13. Because the App does not collect personal data, it is also suitable for use by minors.
You can view, edit, or reset magnet material parameters at any time in the App's "Parameters" settings. You may also delete all locally stored App data by uninstalling the App.

We may update this Privacy Policy from time to time. The updated policy will be posted on this page with a revised "Last Updated" date. If changes materially affect your rights, we will notify you through the App or by other appropriate means.
