MyChoonz is an app for learning Irish traditional tunes: you find tunes from The Session, keep them in a tunebook, build sets and log your practice. This page says what the app stores, where, and how to get it deleted. In short: without an account, everything stays on your device. With an account, your own MyChoonz data is kept in Google Firebase so it can sync between your devices. There are no ads, no analytics and no tracking.

Using MyChoonz without an account

Everything you add (your tunebook, sets, session lists and practice log) is stored only on your device. Nothing is sent to us. Uninstalling the app deletes it.

The app comes with The Session's tunes built in. For the rest, it asks other websites, as a web browser would. These requests send nothing from your tunebook or account, only what any web request carries (such as your IP address):

• mychoonz.app and github.com to keep the built-in tunes up to date: about once a day the app checks mychoonz.app for newer tune data, and downloads it from GitHub when there is some (on Wi-Fi only, unless you allow mobile data in Settings).
• thesession.org for tunes that aren't in the built-in data yet, when you refresh a tune, and, if you import from there, to find your member profile and your tunebook. Those requests are covered by The Session's privacy policy. MyChoonz is not part of The Session.
• paulrosen.github.io (GitHub Pages) for the instrument sounds, the first time each instrument plays.

With an account (optional)

Signing in with Google lets MyChoonz keep your data the same on all your devices. When you sign in, we store:

• from your Google account: your name, email address and a user ID;
• your tunebook: the tunes, their learning status, your notes, preferred settings and tempos;
• your sets and your session lists (the sets you lead at each session);
• your practice log: when you practised which tune, for how long, and at what tempo;
• your member number on thesession.org, if you imported from there.

These are stored in Google Firebase (Authentication and Cloud Firestore), which processes them for us. Only you can read your data; it isn't shared with anyone else, sold, or used for advertising. Your app settings, such as theme and instrument, stay on the device and aren't synced.

Recordings of your playing

When you record yourself, the recording stays on your device. It is never sent to us.

If you turn on Back up recordings to Google Drive (Settings → Account), the app copies your recordings, with when they were made and which tune or set they belong to, to a MyChoonz folder in your own Google Drive. MyChoonz asks Google only for access to files it creates there, so it can’t see anything else in your Drive. The copies are in your Drive, not on our servers: we can’t see them. Deleting a recording in the app deletes the copy too. Turning the backup off keeps the folder unless you choose to delete it; you can also delete it in Google Drive at any time.

MyChoonz’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Keeping and deleting your data

We keep your account data until you delete it. To delete your account and everything in it:

• In the app: Settings → Account → Delete account. It deletes your data from every device and from Firebase, and can't be undone.
• Without the app: see Delete your account.

Signing out removes your data from that device; it stays in your account until you delete the account.
