Terms of Service
Last updated: 11 August 2026
1. Agreement
These terms are an agreement between you and Mastermind Music [DECIDE: legal entity name] (“we”, “us”) covering your use of the Mastermind Music web application and the Mastermind desktop application (together, the “Service”). By creating an account or installing the desktop application you agree to these terms. If you do not agree, do not use the Service.
2. The Service, and its current state
Mastermind Music organises, analyses, and prepares DJ music libraries: importing library metadata, audio analysis (BPM, key, beat grids, cue points), set preparation, and export to other DJ software and devices.
The Service is currently offered free of charge and in active development. Features may change, be added, or be removed without notice. If we later introduce paid plans, we will announce pricing before anything is charged, and no charge will ever be applied without your explicit action.
3. Your account
Accounts are created and authenticated through Clerk, our sign-in provider. You are responsible for the activity that happens under your account and for keeping your sign-in method secure. You must be at least 13 years old to use the Service.
4. Your music and your data
- Your library stays yours. You retain all rights to your music files and your library. The desktop application works on files on your own computer; your audio files are never uploaded to us.
- Metadata you import or create (track titles, artists, playlists, cue points, analysis results) is stored so the Service can function, as described in our Privacy Policy.
- Export is always available. The desktop application can export your library, playlists, cue points and beat grids to standard formats at any time, including if your account is restricted or the Service is discontinued.
- Back up your library. The desktop application makes local backups of its own database, but your music files and your master library remain your responsibility to back up.
5. Acceptable use
You agree not to:
- use the Service to infringe anyone's rights, including copyright in music you do not have the right to use;
- probe, overload, or disrupt the Service, or access it by any automated means beyond its published interfaces;
- resell the Service or misrepresent it as your own;
- attempt to access other users' accounts or data.
The Service reads and writes metadata for music platforms you choose to connect (such as Spotify or Tidal). Your use of those platforms remains governed by their own terms.
6. Telemetry and diagnostics
The desktop application sends usage analytics and crash reports to help us find and fix problems, and you can turn this off at any time in Settings → Privacy & Data. What is and is not collected — and what never is, including your audio files, track names, and file paths — is described in the Privacy Policy, which is part of these terms.
7. Software licence and updates
We grant you a personal, non-exclusive, non-transferable licence to install and use the desktop application for managing your own music library. You may not reverse engineer it except where the law permits.
The desktop application checks for updates automatically and will offer or install them to keep you on a current version. We may remotely restrict the Service (for example, placing the application in a read-only mode) where necessary to protect the Service or its users; your library, and your ability to export it, are never withheld.
8. No warranty
The Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement. In plain words: this is actively developed software; analysis results can be wrong, exports can have defects, and the Service can be unavailable. Verify prepared sets and exported data before performing with them.
9. Limitation of liability
To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for loss of data, profits, or bookings, arising from your use of the Service. Our total liability for any claim is limited to the greater of the amount you paid us in the twelve months before the claim (currently nothing, as the Service is free) or USD $50. Nothing in these terms excludes liability that cannot be excluded by law.
10. Termination
You can stop using the Service and request account deletion at any time (see the Privacy Policy for how). We may suspend or terminate accounts that violate these terms or abuse the Service. On termination for any reason, your right to export your own library from the desktop application survives.
11. Changes to these terms
We may update these terms as the Service evolves. When we make material changes we will update the “Last updated” date above and note the change in the application or by email. Continuing to use the Service after a change takes effect means you accept the updated terms.
12. Governing law
These terms are governed by the laws of [DECIDE: jurisdiction — e.g. England and Wales], and disputes are subject to the exclusive jurisdiction of its courts.
