Independent software for music and audio.
TriCron is a small software company in England. We build desktop tools for music producers and songwriters, focused on audio analysis and arrangement.
TriCron for Mac
A desktop tool for music producers. It turns a finished track into a chord chart and instrument parts, ready for Band-in-a-Box and your DAW. Audio stays on your Mac; only a small summary of numbers is sent to our server.
Requires a Mac with Apple silicon (M1 or later) running macOS 14 Sonoma or later. Windows will follow.
Founding-member access is by invitation.

Privacy policy
Last updated 16 October 2026
This policy covers the desktop apps published by TriCron Limited and the online services they use. TriCron Limited is the data controller for the personal data described here.
What we collect
- Your Google account email and account identifier, when you sign in with Google. We do not request access to your contacts, files, calendar or any other Google data.
- Usage records: when you first signed in and last used the service, and how many analyses your account has run in total and on each day. We use these to apply the daily limit, prevent abuse and understand whether our software is useful.
- Server request logs: for each request to our server, the time, the kind of request, a pseudonymous account ID (derived from your Google account identifier, not your email), whether it succeeded and how long it took. For an analysis, the log also records a fingerprint (a hash) of the summary the app sent, not its contents. The logs don't include your IP address, your email, or any audio or MIDI. We use them to run the service and prevent abuse.
- The notes from your MIDI parts, if you add them. The summary sent for analysis then also includes the notes from those MIDI files (pitch, timing and velocity), used only to produce your chart. As with the rest of the summary, our server does not keep them after responding.
- Emails you send us. If you email support@tricron.com (for support, feedback or the waiting list), we keep your address and your message to reply to you and, for the waiting list, to tell you when that version is available. We delete waiting-list addresses once we have told you, and other emails when they are no longer needed to help you. You can ask us to delete them at any time.
Your audio stays on your computer
Audio separation and analysis run on your computer. Your audio files are never uploaded. To produce a result, the app sends our server a small summary of numerical features derived from the audio (typically a few kilobytes), plus the notes from any MIDI parts you add. The audio features are not audio and cannot be played back. The server uses them to build your result and does not keep them after responding.
What we don't do
- We don't sell your data or share it with advertisers.
- We don't use your data for advertising or profiling.
Where data is held
Our server runs on Microsoft Azure. Sign-in is provided by Google, under Google's privacy policy.
How long we keep it
We keep account and usage records while your account is active. If you ask us to delete your account, we delete these records within 30 days. Server request logs are deleted automatically after 30 days.
Your rights
Under UK data protection law you can ask to see, correct or delete your personal data, or object to how we use it. Email support@tricron.com. If you're unhappy with our response, you can complain to the Information Commissioner's Office at ico.org.uk.
Changes
If this policy changes, we'll update the date above. Significant changes will be shown in the app before they take effect.
Terms of use
Last updated 16 October 2026
These terms cover TriCron for Mac and the online service it uses ("the service"), provided by TriCron Limited, registered in England and Wales (company no. 9312796). By installing or using the service you agree to them. If you don't agree, please don't use it.
Founding-member access
Access is currently free and by invitation. We may change, pause or end the service, or introduce paid plans, at any time. We won't charge you anything without telling you first and getting your agreement.
Your music
Only analyse recordings you own or have the right to use, such as your own productions, or tracks you generated with a service whose terms allow it. You keep all rights to your music and to the charts and parts the app makes from it. Your audio stays on your Mac; the privacy policy explains what the service receives.
Fair use
Use the service for your own music work. Don't try to get around sign-in or usage limits, overload the service, or copy, resell or reverse-engineer it. We may limit or suspend accounts that break these terms.
Accuracy
The app suggests chords and parts automatically. Results can be wrong, so check them by ear before relying on them.
No warranty
The service is provided "as is", without warranties of any kind, to the extent the law allows.
Liability
To the extent the law allows, TriCron Limited isn't liable for indirect or consequential loss, or for loss of data, profits or business, arising from your use of the service. Keep backups of your work. Nothing in these terms limits liability that can't be limited by law, such as for death or personal injury caused by negligence, or for fraud.
Changes
We may update these terms. We'll change the date above and, for significant changes, tell you in the app before they take effect.
Law
These terms are governed by the law of England and Wales.
