Who we are

instrumenttuner.org is operated by M&B Marketing SARL, registered in France (SIREN 837 729 300). We are the data controller for this website.

Microphone access

Tuner pages ask for microphone access only when you press Start. The audio is processed in real time inside your browser to detect pitch. It is never recorded, transmitted to us or stored. You can revoke microphone permission at any time in your browser settings.

Information collected automatically

Our hosting provider, Cloudflare, processes technical data such as IP address, browser type and pages requested in order to deliver and secure the site. We do not ask for your name, email or account details.

Cookies and advertising

This site is free because it may show advertising. Advertising partners and their vendors may use cookies or similar technologies to show ads and measure performance, based on your consent where the law requires it. When advertising is enabled, a consent banner lets you accept or refuse non-essential cookies, and you can change your choice at any time.

Your rights

If you are in the EU, UK or a US state with privacy laws, you may have rights to access, correct or delete personal data, and to object to or opt out of its sale or use for targeted advertising. Because we do not hold accounts or contact details, most requests concern advertising cookies, which you can control through the consent banner and your browser settings.

Children

This site is suitable for all ages and does not knowingly collect personal information from children.

Changes

We will update this page if our practices change, and revise the date above.
