Terms of Use

1. Acceptance

By accessing and using Breve, you agree to these Terms of Use and to the Privacy Policy. If you don't agree, please don't use the service.

2. The service

Breve is a lead-sheet and practice app — jazz, bossa nova, samba, blues and other standards, with harmonic analysis and a metronome. Breve can also read a chart you already have (file, photo, or link) and turn it into a band you can play along with on your device.

3. Account and access

Browsing requires no account. To save favorites and import sheets, you create an account with email and password, or sign in with Apple or Google. You're responsible for keeping your password and account secure and for activity on your account.

• Provide a valid email.
• Report any unauthorized use of your account.
• You can delete your account at any time in the app.

4. Minors

Breve is not directed to children under 13. We recommend guardian supervision for users under 18.

5. Intellectual property

Compositions belong to their respective owners. Breve provides tools for access and study (chord charts and analysis) and claims no ownership over third-party works.

6. Chart import

Import is a tool for material that is yours: only import charts you own or otherwise have the right to use. The content you import stays yours — Breve does not host it, distribute it, or make it available to anyone else.

The scan happens at your request and on your behalf, as your agent, and the result comes back to your device. When you import from a link, your device downloads it straight from the source — never through our servers; complying with that source's terms is your responsibility.

The scan is automatic and can be wrong. Check the result before relying on it (the song screen shows what's left to review). Scanning charts requires an active subscription, with the monthly allowance described in section 8, which we may adjust.

If you have an account, the extracted data is saved to your library (see the Privacy Policy). You warrant that you have the right to use the charts you import and sync. By syncing, you grant Breve a limited licence to store that data and serve it back to you, and only to you — not to publish it, display it to others, or use it to train models. Your library is private and is not reviewed by us.

7. Prohibited conduct

• Using the app for unlawful or unauthorized purposes.
• Interfering with the security or operation of the service.
• Redistributing, copying, or reselling the app's content.
• Importing material you don't have the right to use, or circumventing the scan quota.
• Creating fake or automated accounts.
• Transmitting spam or malicious content.

8. Subscriptions and credits

Breve's paid plans (a monthly subscription, with a 7-day free trial) are sold through the App Store or Google Play and processed by RevenueCat, which manages your purchase state on our behalf — billing and payment method stay with the store, not with us. The free trial converts automatically to a paid subscription at the end of the period unless you cancel first; during the trial, the scan allowance is reduced, shown in the app.

The subscription includes a monthly scan allowance, shown in the app; unused scans do not carry over to the next month. We also sell one-off scan credits, which never expire and are used once the month's allowance runs out. There is a cap on the unused credit balance, enforced only by declining further purchases — credits you already bought are never removed because of the cap.

If a subscription lapses without renewing, nothing is deleted — only what's paid stops working. Your imported charts stay in your library and keep playing with the metronome, exactly like any catalog song on the free tier. Band, the 12 keys, tempo/loop, and harmonic analysis become unavailable until you subscribe again. Resubscribing restores everything immediately on the charts you already have — no re-scan, no allowance spent, because nothing was destroyed, only hidden. Any one-off credit balance you already had isn't lost in the meantime either — and it keeps working: you can still scan with credits while the subscription is lapsed, and the scanned chart opens with the metronome like any free-tier song — only deleting your account forfeits credits, never a simple lapse.

Cancellations and refunds are handled through the store (App Store or Google Play), in your account settings — Breve doesn't process payments or refunds directly. Deleting your account in Breve (Settings → My account → Delete account) ends your access and forfeits any unused scan credits, but does not cancel an active store subscription — it will keep renewing and charging until you cancel it there.

9. Changes

We may update these terms and will notify you when appropriate. You can close your account at any time.

10. Governing law

These terms are governed by the laws of Brazil.
