How We Handle Your Microphone Data
When you use Decimeter.com's sound level meter, you grant your browser permission to access your microphone. Here's exactly what happens with that data:
- 1. Local Processing: Audio from your microphone is processed entirely within your web browser using the Web Audio API.
- 2. No Storage: Audio data is analyzed in real-time and immediately discarded. Nothing is saved to your device or any server.
- 3. No Transmission: Your audio never leaves your device. We have no way to hear, record, or access your microphone data.
- 4. Session-Only: When you close the page or stop measuring, microphone access ends and all data is cleared from memory.
