Privacy policy

Last updated: November 11, 2026

The short version

• Your audio and video never leave your device. Nothing you say or show is uploaded, stored or shared.
• There are no accounts and we don’t ask for your name or email address.
• The site may use basic analytics from Google. Details are below.

Microphone and camera

The tests on this site run entirely in your browser. When you allow access, the audio from your microphone and the picture from your camera are processed by code running on your own device to draw the level meter, waveform and preview.

The optional 5 second recording is kept in your browser’s memory so that you can play it back. It is not sent anywhere, and it is discarded when you close or reload the page. Device details shown in the “Your microphone” panel, such as the device name and sample rate, are displayed to you only and are not collected.

Your browser controls the permission. You can withdraw it at any time from the site settings in your browser’s address bar.

Data stored on your device

If you use the light or dark mode button, your choice is saved in your browser’s local storage so the site looks the same on your next visit. It contains no personal information.

Analytics

We may use Google Analytics to understand how many people visit and which pages are useful. It collects information such as the pages you view, your approximate location, and your device and browser type. It does not collect your audio, your video or your microphone details.

Hosting

The site is hosted on Cloudflare. Like any web host, Cloudflare processes technical information such as your IP address in order to deliver pages and protect the site from abuse.

Children

This site is a general-purpose tool and is not directed at children under 13.

Changes and contact

If this policy changes, the date at the top of the page will change with it. Questions are welcome at [email protected].
