Overview

MathDraft is a visual mathematics notebook for writing formulas, plotting functions, using calculus helpers, drawing geometry figures, organizing notes, and exporting PDF files.

We designed MathDraft to work primarily with your content on your device. We do not sell your personal information.

Information We Do Not Collect

MathDraft does not require you to create an account. The app does not intentionally collect personal information such as your name, email address, contacts, precise location, photos, or payment information.

We do not use the app to track you across other apps or websites.

Your Notes and Files

Your notebooks, formulas, graphs, geometry drawings, images, and exported PDF files are created and stored locally on your device or in locations you choose.

MathDraft does not upload your notebook content to our servers. If you manually share or export a file, that action is controlled by you and may be handled by the destination app, service, or location you choose.

Diagnostics and Support

If you contact us for support by email, we may receive the information you choose to include, such as your email address, screenshots, exported files, device information, app version, and a description of the issue.

We use this information only to respond to your request, troubleshoot problems, and improve MathDraft.

Third-Party Services

MathDraft may rely on platform features provided by Apple and macOS, such as file access, save dialogs, printing, or PDF handling. These features are governed by Apple’s privacy practices and your device settings.

This privacy policy does not cover third-party websites, cloud storage providers, email providers, or other services you choose to use with exported or shared files.

Data Security

Because your content is primarily stored locally, you are responsible for protecting your device, backups, and exported files. We recommend keeping your macOS device secure and using trusted storage locations.

Children’s Privacy

MathDraft does not knowingly collect personal information from children. If you believe a child has provided personal information through a support request, please contact us and we will take appropriate action.

Changes to This Policy

We may update this Privacy Policy from time to time. When we make changes, we will update the “Last updated” date on this page.
