Privacy Policy

Last updated: April 12, 2026

Our Commitment to Privacy

At HzGenerator, we are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our audio tone generation service.

Information We Collect

Information We DO NOT Collect

  • Personal identification information
  • Audio data or generated tones
  • Usage patterns or frequency preferences
  • Device information or browser fingerprints
  • Location data

Information We May Collect

  • Basic website analytics (page views, general geographic region)
  • Technical error logs for debugging purposes
  • Contact information if you voluntarily provide it through our contact form

How We Use Information

Any information we collect is used solely for:

  • Improving the functionality and performance of HzGenerator
  • Responding to your inquiries and providing customer support
  • Identifying and fixing technical issues
  • Understanding general usage patterns to improve our service

Data Storage and Security

HzGenerator operates entirely in your browser using the Web Audio API. All audio generation happens locally on your device, and no audio data is transmitted to our servers. We implement appropriate security measures to protect any information we do collect.

Analytics and Tracking

We may use privacy-respecting analytics tools to understand aggregate usage patterns, such as which pages are visited most frequently and general geographic regions of users. These tools do not identify you personally. We do not use advertising trackers, cross-site tracking pixels, or sell data to any third party. You may opt out of analytics by enabling the "Do Not Track" setting in your browser.

Third-Party Services

We may use third-party services for website analytics and hosting. These services have their own privacy policies, and we encourage you to review them. We do not share personal information with third parties for marketing purposes.

Cookies and Local Storage

HzGenerator may use browser local storage to remember your preferences (such as frequency settings) between sessions. This data remains on your device and is not transmitted to our servers. You can clear this data at any time through your browser settings.

Data Retention

Because HzGenerator does not collect personal data in the traditional sense, there is no personal data to retain or delete. Any browser-based preferences stored via local storage remain on your device indefinitely until you clear your browser data. Server-side technical logs, if retained at all, are kept for no longer than 30 days and are used solely for debugging and service improvement.

You have the right to:

  • Request information about any data we may have collected
  • Request deletion of any personal information
  • Opt out of any data collection
  • Contact us with privacy-related questions or concerns
