Agreement
By downloading, installing or using Downbeat ("the App"), you agree to these Terms of Use. If you don't agree, don't use the App.
This agreement is between you and Sebastian Guerrero ("Developer"), not with Apple Inc. Apple is not responsible for the App or its content.
License
The Developer grants you a limited, non-exclusive, non-transferable, revocable license to use the App on any Apple device that you own or control, as permitted by the Usage Rules in the App Store Terms of Service.
You may not:
- Copy, modify or distribute the App
- Reverse engineer, decompile or attempt to extract the source code or bundled models of the App
- Circumvent or interfere with the App's subscription features
- Use the App for any unlawful purpose
Free Features and Downbeat Studio Pro
The Metronome and Tuner, including the Apple Watch app, are free.
Jam and Songs require Downbeat Studio Pro, available as a monthly or yearly auto-renewable subscription. One subscription unlocks Pro on all of your iPhone, iPad and Mac devices signed in to the same Apple Account.
Subscriptions
By subscribing to Downbeat Studio Pro:
- Payment is charged to your Apple Account at confirmation of purchase
- Your subscription automatically renews unless cancelled at least 24 hours before the end of the current period
- Your account is charged for renewal within 24 hours before the end of the current period
- You can manage and cancel your subscription in your App Store account settings
- Any unused portion of a free trial is forfeited when you purchase a subscription
- Refunds are handled by Apple under its own refund policies
When Pro Ends
If your subscription ends, songs you imported stay in your library, but playback is limited to the first 15 seconds of each song, and Jam and new song imports are unavailable. Full access returns as soon as you subscribe again or restore an active purchase.
Your Music
Songs supports audio files that you choose to import. You are responsible for making sure you have the right to use any audio you import.
Downbeat is intended for personal practice and learning. Separated tracks, chords, keys and tempos are created for your own use within the App. Don't use the App to infringe the copyright or other rights of anyone else.
Accuracy
Track separation, chord, key and tempo detection, and the tuner are produced automatically and may not always be accurate. Results depend on the recording, your device and the environment you're playing in.
Third-Party Components
The App includes the following open-source components, each used under its own license:
- Demucs (Hybrid Transformer Demucs) for track separation, © Meta Platforms, Inc. and affiliates, MIT License
- BTC (Bi-directional Transformer for Chord Recognition), © 2019 Jonggwon Park, MIT License
- GeneralUser GS SoundFont for Jam's instruments, by S. Christian Collins, GeneralUser GS License v2.0
The App uses RevenueCat to manage subscriptions, and Apple's iCloud for optional sync, each subject to their own terms. These components are also credited in the App under Settings → Acknowledgements.
Disclaimer of Warranties
The App is provided "as is" and "as available", without warranty of any kind, to the extent permitted by law. The Developer does not warrant that the App will be uninterrupted or error-free, or that defects will be corrected. Nothing in these Terms affects your statutory rights as a consumer.
Limitation of Liability
To the fullest extent permitted by law, the Developer is not liable for any indirect, incidental, special or consequential damages arising from your use of the App, including loss of data. Nothing in these Terms limits liability that cannot be limited by law.
