MicTest ("we", "us", or "the website") respects your privacy. This Privacy Policy explains what information we do and do not collect when you use our free online microphone test, and how advertising and cookies work on this site. By using MicTest, you agree to the practices described here.
This is the most important thing to know: MicTest never uploads, stores, or transmits your microphone audio. All microphone processing — the live waveform, the volume meter, and the optional record-and-download feature — happens entirely within your web browser using standard Web Audio and MediaRecorder technologies. Any recording you make is saved only to your own device when you choose to download it. We never receive it.
Like most websites, standard technical information (such as browser type, device type, approximate region, and pages visited) may be collected through analytics and advertising services to help us understand usage and keep the site running. Your language and theme preferences are stored locally in your browser (using localStorage) so the site remembers your choices — this data stays on your device.
MicTest itself does not require cookies to function. However, third-party services we use — in particular advertising partners — may set cookies on your device to deliver and measure ads. You can control or delete cookies through your browser settings at any time. Disabling cookies will not prevent you from using the microphone test.
This website may display advertisements served by Google AdSense and other third-party vendors. In accordance with Google's policies:
We do not control the cookies or data practices of these third parties. We encourage you to review Google's own Privacy & Terms for details on how they handle data.
If you are located in the European Economic Area, the United Kingdom, or California, applicable laws (such as the GDPR and CCPA) give you rights over your personal data, including the right to access, correct, or delete it, and to object to personalised advertising. Where required, our advertising partners will request your consent before using cookies for personalisation. You may withdraw consent or exercise your rights by adjusting your browser settings or contacting us.
MicTest is a general-audience tool and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information, please contact us so we can address it.
Because your audio is processed locally and we collect no accounts or personal profiles, there is very little personal data for us to secure. For the limited technical data handled by our analytics and advertising partners, those providers maintain their own industry-standard security measures.
Our site may contain links to external websites (for example, opt-out pages or Google policies). We are not responsible for the privacy practices or content of those sites. Please review their policies separately.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with a revised "Last updated" date. Continued use of the site after changes means you accept the updated policy.
If you have any questions about this Privacy Policy or how your data is handled, please reach out through our Contact page or email contact@123mictest.com.
