Chorustr — Privacy Policy

Who this applies to

This policy covers everyone who creates a Chorustr account — both choir members (singers who join a choir to access practice materials) and choir leaders (organisers who create and manage choirs). Where there are differences between the two roles, they are noted below.

What we collect

When you create a Chorustr account we collect the following personal data:

Given name and family name — sourced from the Apple or Google account you use to sign in.
Email address — sourced from your Apple or Google account.
Consent timestamp — the date and time you agreed to this policy, recorded when your account is created.
Choir membership history — a record of which choirs you have joined and when, linked to your account.

Choir leaders additionally have their choir management activity recorded (choirs created, claimed, or transferred).

We do not collect your credentials, your device advertising ID, or any information about how you use the app beyond what is described above.

How we use your data

Your data is used solely for choir administration:

To identify you when you sign in and display your name in the app.
To maintain your choir memberships so you can access your choir's practice materials.
To allow choir leaders to see who has joined their choir, attended rehearsals and accessed practice materials.
To send you service-related communications (e.g. email confirmation of account deletion).

We do not use your data for advertising, profiling, or any purpose unrelated to running Chorustr. We do not sell or share your data with third parties, except as described under "Service providers" below.

Authentication providers

Chorustr uses Sign in with Apple and Sign in with Google. When you sign in, you are redirected to Apple or Google to authorise the app. We never see your Apple or Google password. The identity information Apple or Google returns to us (your name and email) is governed by their respective privacy policies:

Service providers

Chorustr is built on Google Firebase, which provides our authentication service (Firebase Auth) and database (Firestore). Your account data is stored in Firebase infrastructure located in the EU (europe-west2 region). Google processes this data on our behalf under a Data Processing Agreement and does not use it for its own purposes.

Practice audio files are stored in and delivered from Dropbox. Chorustr holds a service-account token that allows the API to generate short-lived, per-file download links for your choir's content. Your individual identity is not shared with Dropbox.

Data retention

Your personal data is kept for as long as your account exists. When you delete your account:

Your user profile (name, email, consent timestamp) is permanently deleted from our database.
All choir membership records associated with your account are permanently deleted.
Your Chorustr authentication record is removed, signing you out of any active sessions.

Deletion is irreversible. You are free to create a new Chorustr account at any time. We do not retain backups of individual account data beyond our standard database backup window (30 days), after which all traces are gone.

Your right to deletion

You can delete your account at any time. There are two ways to do this:

In the app: Go to Settings → Account → Delete Account. This immediately removes your profile, memberships, and Firebase Auth account.
By email: Send a deletion request to support@chorustr.com from the email address associated with your account. We will process your request within 30 days.

You also have the right to access a copy of the personal data we hold about you. To request this, email support@chorustr.com.

Audio content

The practice tracks available in the app are provided by your choir leader. Chorustr does not own or have any responsibility for the copyright of audio content shared by choir leaders. By joining a choir you agree to any licence terms your choir leader applies to those materials.

Changes to this policy

If we make material changes to this policy we will notify you via the app before the changes take effect and, where required by law, ask for your renewed consent.
