Privacy Policy & Disclaimer

iOS app

• The iOS app does not ask for your name, email address, or any other personal information.
• Your settings (such as clef, Do system, and volume) are stored only on your device.
• Purchases are handled by Apple. To check whether you have a subscription, the app uses RevenueCat, which works with an anonymous ID that it creates for your device. We do not send your name or email address to RevenueCat.
• When you play a paid song, the app sends this anonymous ID to our server to confirm your subscription. The server keeps only the result ("subscribed") for about 10 minutes, and does not record your IP address or which songs you play.
• The app does not use advertising, tracking, analytics, or crash-reporting services.

Web app

To use the paid songs in the web app, you sign in with your email address. There is no password: we send you a 6-digit code or a sign-in link by email.

We store the following on our server:

• Your account: your email address, your customer and subscription IDs at Paddle, and your subscription status and end date.
• Signed-in devices (up to 2): a scrambled (hashed) form of the sign-in key for each device, and the dates it was created and last used. A device that is not used for 4 months is removed.
• Sign-in emails: a short-term record of the codes and links we sent, deleted within 1 day.

We do not store your name, address, or card number. We do not record your IP address or which songs you play. Your settings are stored only in your browser.

Payments (web app)

Payments for the web app are processed by Paddle, our reseller and the merchant of record. Paddle collects your payment details and billing information under its own privacy policy.

Services we use

• Cloudflare: hosts our websites, server, and database, and delivers the audio and sheet music files. Like any web host, Cloudflare may process technical data such as IP addresses to deliver and protect the service.
• Resend: sends the sign-in emails for the web app.
• Paddle: processes payments for the web app.
• RevenueCat and Apple: handle purchases in the iOS app.

We do not sell or share your data for advertising.

Links to other sites

The app and this site link to other sites, such as Wikipedia, IMSLP, Apple Music, and Spotify. Those sites have their own privacy policies.

Deleting your data

To delete your web app account and the data we store about it, email [email protected] from the email address you use to sign in. If you have an active subscription, please cancel it first. Records that Paddle must keep for tax and legal reasons are kept by Paddle.

For the iOS app, we do not hold any personal data. To remove the data on your device, delete the app.

Changes to this policy

If we change this policy, we will update this page and the "Last updated" date.
