Privacy Policy
Short version: the microphone feeds this page only, and no audio is stored.
Short version
The microphone feeds this page and nothing else. Audio is never recorded, never uploaded and never written to storage. Pressing stop releases the microphone and closes the audio context.
What happens to the audio
- It stays in memory. Each block of samples is read once, reduced to a single loudness number, then overwritten by the next block.
- No recording. The page does not use MediaRecorder, does not build an audio file and offers no download.
- No upload. There is no network request carrying audio. The meter keeps working if the connection drops after the page has loaded.
- No storage. Levels, peaks and averages live in page memory only. Reload and they are gone; there is no cookie, no local storage and no database row.
Permission and release
The browser asks for microphone permission the first time you press start. The page cannot open the microphone without that prompt, and it cannot reopen it silently after you stop: pressing start again asks the browser to resume the stream. Closing or reloading the tab also ends the stream. The indicator light or dot on your device should go out when the meter stops — if it does not, the browser or another tab still holds the microphone.
What the server sees
Like any website, the server receives the request for the page: URL, time, IP address and user agent. Those requests are used to serve pages and to count aggregate traffic. They do not contain audio and cannot be linked to a measurement.
Third parties
The pages load no third-party scripts, fonts, images or embeds. There is no advertising network and no analytics service. If that ever changes, this page will say so before the change ships.
Limits of the promise
Processing happens in your browser, which means the page can only protect what it controls. Anyone with access to your screen, your browser profile or your device can see the current reading. A browser extension with microphone permission operates outside this page's control and is not covered by anything written here.
Children
Nothing is collected, so there is nothing to collect from a child. A parent or teacher should still supervise use, because the tool encourages listening to loud environments rather than avoiding them.
Contact
Privacy questions can go through the contact link on the main site. There is no dedicated privacy mailbox for this tool cluster.
