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.
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.
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.
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 does not run a separate analytics service.
Where consent is required for advertising cookies or similar technologies, TuneToy will present a consent message and respect the choice made before serving personalized advertising.
This policy may change when the site's services change. The effective date above will be updated when that happens.
