Privacy Policy

Last Updated: December 27, 2024

Overview

NullField Lab ("we", "our", or "the application") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our electromagnetic field compensation application.

Key Principle: NullField Lab is a client-side application that runs entirely in your web browser. We do not collect, transmit, or store any personal data on external servers.

Data We Do NOT Collect

NullField Lab does not collect or transmit:

Local Data Processing

All data processing occurs locally on your device:

Magnetometer Access

The application requests access to your device's magnetometer sensor to detect electromagnetic field strength and frequency. This data:

  • Is processed entirely within your browser
  • Is never transmitted to external servers
  • Is not stored permanently (only used during active sessions)
  • Is discarded when you close the application

Audio Generation

The application uses Web Audio API to generate compensatory tones through your headphones. Audio synthesis occurs locally in your browser's audio context. No audio is recorded or transmitted.

Browser Local Storage

The application may use browser local storage to save your preferences (such as preferred frequency settings or volume levels). This data:

  • Remains on your device only
  • Can be cleared by clearing your browser's local storage/cookies
  • Is not accessible to other websites or applications
  • Is never transmitted to external servers

Permissions Required

NullField Lab requires the following browser permissions to function:

Magnetometer Access

Purpose: To detect electromagnetic field strength and grid frequency in your environment

Scope: Read-only access to sensor data; no data storage or transmission

Audio Playback

Purpose: To generate and play compensatory frequency tones through your headphones

Scope: Audio output only; no microphone access or audio recording

You can revoke these permissions at any time through your browser settings. Revoking permissions will prevent the application from functioning but will not affect any data (as none is collected).

Third-Party Services

NullField Lab does not integrate with third-party analytics, advertising, or tracking services. The application is hosted as a static website and does not communicate with external APIs or servers during normal operation.

External Resources: The application loads the following external resources:

These resources are loaded from content delivery networks (CDNs) and are subject to their respective privacy policies. No personal data is transmitted when loading these resources.

Cookies

NullField Lab does not use cookies for tracking, analytics, or advertising purposes. The application may use browser local storage (similar to cookies) to save your preferences locally on your device. This is purely for improving your user experience and can be cleared at any time.

Children's Privacy

NullField Lab does not knowingly collect any information from children under the age of 13. The application does not require users to provide any personal information. If you are a parent or guardian and believe your child is using the application, you may restrict access through parental controls on their device.

Data Security

Since NullField Lab does not collect, transmit, or store personal data on external servers, there is minimal security risk associated with using the application. All processing occurs locally on your device within your browser's security sandbox.

Your Responsibility: You are responsible for:

International Users

NullField Lab can be accessed from anywhere in the world. Since all processing occurs locally on your device and no data is transmitted to external servers, there are no cross-border data transfer concerns. The application complies with GDPR, CCPA, and other privacy regulations by design through its privacy-first, local-only architecture.

Your Rights

Since we do not collect or store your personal data, traditional data subject rights (access, rectification, deletion, portability) are not applicable. However:

Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in the application or legal requirements. Any changes will be posted on this page with an updated "Last Updated" date. Since we do not collect contact information, we cannot notify you directly of changes. We encourage you to review this Privacy Policy periodically.

Contact Information

If you have questions about this Privacy Policy or NullField Lab's privacy practices, you can contact us through the project repository or documentation channels.

Privacy-First Design

NullField Lab was designed with privacy as a core principle. By processing all data locally on your device and never transmitting information to external servers, we ensure your privacy is protected by default. You maintain complete control over your data at all times.
