Privacy Policy

Last updated: September 27, 2026

If you sign in with Google, we store your Google account identifier, name, email address, profile image, and a session cookie to create your account and restore purchases. We do not receive your Google password. Signing out ends your current session.

Before a sign-in or checkout redirect, your current drawing is temporarily saved in this tab's session storage and restored when you return. This draft is not uploaded as part of signing in.

When purchases are available, Stripe or PayPal processes payment details, depending on the option you choose. We retain order and payment identifiers, purchase status, and the website account that owns the purchase. Your payment details are not used to match you to a different website account.

Optional rewarded ads, when enabled, are provided by Google Ad Manager. They load only after you choose to watch an ad and applicable privacy choices have been checked. A temporary reward expiry time is stored locally in this browser for up to 30 minutes. This is separate from analytics consent.

Play Music Theory uses Google Analytics 4 to understand aggregate website traffic and how visitors use the instrument. Analytics storage is disabled by default and is enabled only when you choose “Allow analytics.”

We do not send names, email addresses, drawings, published piece contents, or other directly identifying information to Google Analytics. Advertising storage, Google Signals, and ad personalization are disabled.

If you choose “Not now,” Google Analytics remains in consent-denied mode and does not write analytics cookies. Google may still receive limited, cookieless measurement signals. Your choice is stored in your browser so the site can remember it.

You can clear this choice at any time by removing this site’s local storage in your browser. Google’s handling of Analytics data is described in the Google Privacy Policy.
