Privacy Policy

Last updated: January 2026

Summary: PlotCraft collects zero data. All equation processing happens locally on your device. Your mathematical work never leaves your iPhone or iPad.

Our Privacy Commitment

PlotCraft is built with privacy as a core principle. We believe your mathematical exploration is personal, and we've designed the app to ensure your work remains completely private.

Data Collection

We do not collect any personal data. This means:

  • No personal information is collected
  • No usage analytics or tracking
  • No crash reports sent to external servers
  • No advertising identifiers
  • No third-party analytics SDKs

Equation Processing

All graphing and calculations happen entirely on your device:

  • Equations are never uploaded to any server
  • No cloud processing is used
  • No network requests are made during use
  • The app works completely offline

Local Data Storage

PlotCraft stores minimal data locally on your device:

  • Your saved equations
  • Theme preferences (Dark, Light, or Midnight)
  • Display settings (grid lines, axis labels)

This data is stored only on your device using iOS's UserDefaults and is never transmitted anywhere. Uninstalling the app removes all locally stored data.

No Account Required

PlotCraft does not require any account creation or sign-in. There is no registration, no email collection, and no user profiles.

Third-Party Services

PlotCraft does not integrate with any third-party services that collect data. The only external connection is to Apple's App Store for app distribution, which is handled entirely by Apple.

Built with Pure SwiftUI

PlotCraft is built entirely with native SwiftUI, with no third-party libraries or SDKs. All equation parsing and graphing functionality is implemented in-house, ensuring complete control over your data.

Children's Privacy

Since we don't collect any data, PlotCraft is safe for users of all ages. This makes it ideal for students learning mathematics.
