Cookie Policy

Last updated: June 2026

This Cookie Policy explains how OnlineViolinTuner.com uses cookies and similar tracking technologies when you visit or interact with this website. It describes what cookies are, which specific cookies this site uses and why, and how you can manage or disable them.

OnlineViolinTuner.com is operated by Mason (contact available via the Contact page).

By continuing to use this website, you consent to the use of cookies as described in this policy. You may withdraw consent at any time by adjusting your browser settings or using the opt-out options described below.

What Are Cookies

Cookies are small text files stored on your device — computer, phone, or tablet — when you visit a website. They allow the website to remember certain information about your visit and to provide services like analytics and advertising.

Cookies do not contain executable code and cannot access other files on your device.

Cookies This Site Does NOT Use — Audio and Tuning Data

Because the violin tuner on this site processes microphone audio in real time using the Web Audio API, it is important to state clearly that this site does not use cookies to:

Store, access, or transmit any audio input from your microphone
Track your tuning sessions, string readings, or cents deviation history
Build profiles based on your tuning activity or playing patterns
Connect your microphone use to any advertising identifier or personal profile

Your violin playing, your tuning session results, and your use of the tuner are never linked to any cookie, tracking identifier, or analytics profile. The audio processing pipeline and the cookie systems on this website are entirely separate.
