Advertising, cookies and consent
Advertising is optional: Google AdSense loads ads below the tuner and between page sections only when configured for this website. Without that configuration, neither the AdSense script nor ads load. When advertising is enabled, Google and its partners may use cookies or similar technologies and receive technical data such as IP address and browser information to deliver and measure ads. Microphone audio is processed locally, is never uploaded and is not used for advertising.
When advertising is configured, Google’s consent message provides the required choices in the European Economic Area, the UK and Switzerland. You can accept, reject or manage purposes there. Once that message is available, Privacy settings appears in the footer to change or withdraw your choice. This link is absent when advertising is disabled or the consent interface is unavailable. You can also block or delete cookies in your browser. The tuner works independently of advertising consent.
Preferences on your device
Reference pitch, note names, sound, vibration, reference-tone timbre, whether pitch history and stage mode are enabled, ukulele size and High G or Low G, each instrument’s last tuning (guitar, bass and ukulele), custom tunings for each instrument, chromatic mode, sustained reference tones, whether you closed the language hint, and theme may be saved in your browser’s local storage. Custom tuning names and pitches stay on this device. Clear this site’s browser data to remove all these preferences; Reset in the tuner settings restores the tuner defaults.
Analytics
Only configured services such as Plausible or Umami load analytics scripts. The intended audience measurement works without cookies. See the Privacy page for technical request data and your rights.
