Privacy Policy
TuneToy is designed to tune an instrument without collecting the sound being analyzed.
Effective July 9, 2026
Microphone audio
TuneToy uses your browser's microphone permission only after you choose Start tuning. Audio is processed locally in your browser to calculate pitch. TuneToy does not record, upload, transmit, or store your microphone audio.
Settings stored on your device
The tuner saves your selected tuning, A4 reference, chime preference, and chosen microphone label in your browser's local storage. This information remains on your device and can be removed by clearing this site's browser data.
Hosting and security
TuneToy is hosted by Cloudflare. Like most web hosts, Cloudflare may process limited technical information needed to deliver and protect the site, such as IP address, browser request headers, and security events. TuneToy does not operate user accounts or maintain a database of tuner activity.
Advertising and analytics
TuneToy uses Google AdSense code on pages that may display advertising. Google and its advertising partners may process information such as cookie or local-storage identifiers, IP address, device information, and browsing activity to deliver, limit, measure, and personalize advertising, subject to your location and choices.
TuneToy uses Google Analytics 4 to measure page views, browser and device categories, referring pages, and interactions with the tuner. Tuner events may report when tuning starts, the selected tuning, the result of a microphone permission request, a string lock, a string reaching tune, or completion of a tuning. These events never include microphone audio, detected pitch or frequency, microphone or device labels, or message content.
Advertising storage and advertising-related data use are disabled by default. For visitors in the European Economic Area, United Kingdom, and Switzerland, analytics storage also defaults to denied unless the visitor grants consent through an available consent interface. Google may receive limited cookieless measurement signals while storage is denied.
