VectorVisualizer · Last updated: June 2026

Overview

VectorVisualizer is a 3D mathematics visualisation tool for plotting vectors, points, and line segments in three-dimensional space.

Short version: the app collects nothing. Zero.

Data Collection

VectorVisualizer does not collect, store, transmit, or share any personal data, usage data, analytics, or diagnostic information of any kind. Specifically:

• No account or login is required.
• No names, email addresses, or contact details are ever requested or stored.
• No usage analytics or crash reports are sent anywhere.
• No advertising identifiers (IDFA or otherwise) are accessed.
• No third-party SDKs that collect data are included in the app.
• The app makes no network requests. All content is bundled locally on your device.

Local Preferences Storage

The only storage the app uses is browser localStorage inside its built-in web view, saving UI preferences entirely on your own device. This data is never transmitted to any server.

You can clear this data at any time by deleting and reinstalling the app.

Children's Privacy (COPPA)

VectorVisualizer is designed as an educational tool suitable for all ages, including children under 13. Because the app collects no data whatsoever, it fully complies with COPPA and equivalent regulations worldwide.

Third-Party Services

The app contains no third-party services, advertising networks, analytics libraries, or tracking pixels. All JavaScript libraries (Three.js, Tailwind CSS) are bundled locally and operate entirely offline.

Data Security

Since no personal data is collected or transmitted, there is no data in transit or at rest to protect beyond the standard iOS device security that Apple provides.

Changes to This Policy

If the app's data practices ever change, this policy will be updated and the "Last updated" date will be revised.
