Chordical: Guitar Tuner asks for the microphone so it can hear your guitar. The audio is analyzed on your device in real time to find the pitch of the string you play. It is never recorded, never stored and never sent anywhere.

The app has no account and collects no data. It contains no analytics, no advertising and no tracking.

This section covers the iPhone and iPad app and the website sheetmusic.chordical.com, along with its guitar, voice and drum sites. There is no account and no sign in.

MIDI keyboards

When you connect a MIDI keyboard over USB, a network MIDI session or Bluetooth LE, the notes it sends are handled on your device. They are used only to check the notes you play against the score and to light the keys on screen. They are not stored and not uploaded.

Microphone

The microphone is used only while a guitar or voice piece is listening. The audio is analyzed on your device to find the pitches you play or sing. It is not recorded and not uploaded. Piano and drum pieces do not use the microphone.

What is stored on your device

• Your settings, such as the theme, the volumes and the MIDI input to listen to.
• The pieces you played recently.
• The Bluetooth keyboard you connected last, so the app can reconnect to it.

On the web these are kept in your browser's storage for the site. In the iPhone and iPad app they are kept in the app's own storage. Clearing the site's data in your browser, or deleting the app, removes them.

Downloads

Pieces and audio samples are downloaded from sheetmusic.chordical.com, guitarsheetmusic.chordical.com and voicesheetmusic.chordical.com. These requests carry nothing that identifies you.

Cloudflare Web Analytics
