Privacy

Updated November 9, 2026.

We store only your email address and Google's stable account ID as account identifiers from Google sign-in. We do not store your name, photo, or phone number. We use these identifiers for sign-in, linking your library, and managing teacher quotas.

Your account also has a creation time, plan, and login sessions. If you use the library, we store the scores or chord charts and practice settings you choose to save. Teacher usage records contain daily request and token counts.

Account data is stored in Cloudflare D1 in Asia-Pacific until you delete your account. A secure cookie keeps you signed in; the database stores only a hash of its session token. Sessions expire after 30 days, and expired sessions are deleted when used again.

When you use “Ask the teacher”, your question and the arrangement explanations for selected bars are sent to Anthropic's Claude API to generate a response. Your email and Google account ID are not included in that request. Please avoid putting personal information in questions. This processing happens only when you use that feature.

Choose Account → Delete account in the app and confirm to immediately delete your account, all sessions, saved library, and teacher usage records. Signing in again creates a new account.

Analytics

We use Google Analytics 4 (Google LLC) to understand pages viewed and use of the practice bench: opening the bench, loading a tune, starting playback, signing up or signing in, saving a tune, and reaching the free library limit. It also measures device and browser type and approximate location.

Analytics sets first-party cookies named _ga and _ga_*. We do not use analytics for advertising. We do not send email addresses, Google account IDs, internal user IDs, tune titles, or chart text to Google. Product events contain only categories such as source type, style, level, mode, and plan.

Visitors in the European Economic Area, the United Kingdom, and Switzerland are asked before Google Analytics loads. If we cannot determine your country, we also ask first. Elsewhere analytics is enabled unless you decline. Your choice is saved in your browser. Cloudflare provides a country code to make this decision; Bluesify does not log or store it.

Our host, Cloudflare, also counts page loads with Cloudflare Web Analytics. It sets no cookies and does not identify you; it reports aggregate page views, referrers, browser type, country, and page load timing. Pages load the Fraunces and Inter fonts from Google Fonts, so your browser requests them from Google's font servers.

You can change your choice at any time through Cookie settings here, in the landing footer, or under Account or Practice in the bench. Declining stops further analytics collection. You can also use Google's Analytics opt-out browser add-on.

Analytics event data is retained for 14 months, as configured in Google Analytics. This retention is separate from the account data described above.
