Privacy Policy for graph

Last updated: November 13, 2025

Overview

graph ("we", "our", or "the app") is committed to protecting your privacy. This privacy policy explains our data practices for the graph graphing calculator application.

Data Collection

graph does NOT collect, store, or transmit any personal data.

We do not:

• Collect personal information
• Track your usage or behavior
• Use analytics services
• Display advertisements
• Share data with third parties
• Require account creation or sign-in

All calculations and mathematical operations are processed entirely on your device.

Data Storage

The app stores the following data locally on your device only:

• Mathematical functions you create and save
• Calculator history and previous calculations
• App settings and preferences
• Matrix values you enter

This data never leaves your device and is not accessible to us or any third parties. The data is stored using Apple's SwiftData framework and is protected by your device's security features (encryption, passcode, Face ID, Touch ID).

Third-Party Services

graph does not use any third-party services, including:

• Analytics services (no Google Analytics, Firebase, etc.)
• Advertising networks
• Crash reporting tools
• Social media integrations
• Cloud storage services

Internet Connectivity

graph does not require an internet connection to function. The app works completely offline and does not communicate with any servers.

Data Security

All data is stored locally on your device using Apple's SwiftData framework. Your data is protected by:

• Your device's built-in security (encryption at rest)
• Your device passcode, Face ID, or Touch ID
• iOS/iPadOS/macOS security features and sandboxing

If you delete the app, all locally stored data is removed from your device.

iCloud Sync

Currently, graph does not support iCloud sync. All data remains on the device where it was created. If this feature is added in the future, it will be:

• Optional and opt-in
• Encrypted end-to-end
• Stored in your personal iCloud account (not accessible to us)

Children's Privacy

graph is safe for users of all ages, including children under 13. We do not collect any personal information from anyone, including children. The app complies with the Children's Online Privacy Protection Act (COPPA).

Your Rights

Since we don't collect any data, there is no personal information to:

• Access or request
• Delete or modify
• Export or transfer

You have complete control over your data by managing it directly within the app or by deleting the app from your device.

Changes to This Policy

We may update this privacy policy from time to time to reflect changes in the app or legal requirements. Any changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
