Privacy Policy

1. Zero Voice Data Collection

When you use our Vocal Range Test, Hatsune Miku Challenge, Rate My Singing tool, or Frequency Detector, your web browser requests temporary access to your microphone via navigator.mediaDevices.getUserMedia.

This audio stream is processed strictly in your local device memory using the W3C WebAudio API. We do not record, store, compress, log, or transmit any audio packets to any remote server or third-party service. Once you stop the microphone or close the tab, all audio buffers are immediately flushed from RAM.

2. Audio File Pitch Detector Privacy

When you upload MP3, WAV, or M4A files to the Audio File Pitch Detector, files are decoded in-browser using AudioContext.decodeAudioData. Your audio files are not uploaded to our servers or any cloud storage bucket.

3. Cookies and Advertising (Google AdSense)

VocalRange.me may display third-party advertisements provided by Google AdSense to support the free operation of our servers. Google uses cookies to serve ads based on your prior visits to this website or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings.

4. Web Analytics

We may collect standard, anonymized server access telemetry (such as page views, browser user-agent, operating system, and general geographic country) to improve website performance, eliminate bugs, and optimize page load speeds.
