Privacy policy
Published: · Last updated:
This policy explains what happens when you use the browser-based sound tools and visit the site.
Microphone audio
SoundLevelTest processes microphone audio in your browser using the Web Audio API. The audio is processed in memory on your device and is not recorded, stored, or transmitted to a remote server.
Selecting Stop, leaving the page, or closing it releases the microphone. Reloading the page does not preserve audio or measurements. Microphone access is controlled by your browser, and you can revoke permission in its site settings.
Local setting
If you change the calibration offset, that numeric setting is stored in your browser so it can be reused. It is not an audio recording. Clearing this site's browser storage removes the saved offset.
Analytics
The site uses Google Analytics to understand page visits and general site use. Microphone audio, sound samples, and meter readings are not sent to analytics. Analytics may process information such as page visits, browser type, approximate location derived from network information, and device category according to Google's service settings and policies.
External links
Guides link to independent sources including public agencies and the author's LinkedIn profile. Their privacy practices apply after you follow those links.
Questions
For privacy questions or correction requests, contact SoundLevelTest.com.
No accounts or personal profiles
The tools work without registration, sign-in, or payment. The site does not ask for your name, email address, or phone number in order to use the meter or speaker test. If you choose to email the site, your message and address are used only to reply and to handle the issue you raised.
Your choices
You can deny or revoke microphone permission at any time, block analytics with browser privacy settings or extensions, and clear site data to remove the saved calibration offset. The meter keeps working when analytics is blocked. If this policy changes in a way that affects how data is handled, the page will be updated.
