Privacy Policy

Last updated: September 30, 2026

1. Overview

Free Hz Generator ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how our website at freehzgenerator.com handles information when you use our free online tone generator and audio tools.

Short version: We collect virtually no personal data. All audio generation happens locally in your browser using the Web Audio API. Nothing is sent to our servers.

2. Information We Do Not Collect

Free Hz Generator does not collect, store, or transmit:

  • Personal identification information (name, email, phone number)
  • Audio recordings or frequency data you generate
  • Downloaded WAV files or session parameters
  • Biometric or health data
  • Payment information (the service is entirely free)
  • Account credentials (no account is required)

3. Information Collected Automatically

Like most websites, our hosting provider may automatically log standard technical information including:

  • IP address (anonymised)
  • Browser type and version
  • Operating system
  • Referring URL
  • Pages visited and time spent
  • Date and time of access

This data is used solely for server security and aggregate traffic analysis. It is not linked to any individual identity and is not sold to third parties.

4. Cookies & Local Storage

We use browser localStorage (not cookies) to remember your preferences:

Free Hz Generator is suitable for all ages. We do not knowingly collect any personal information from children under the age of 13. If you believe a child has provided personal information, please contact us and we will promptly delete it.

7. Your Rights

Depending on your jurisdiction, you may have the right to:

  • Access any personal data we hold about you
  • Request correction or deletion of your data
  • Object to or restrict processing
