Matra Studio — Terms of Service
Last updated: 2026-07-05.
By using Matra Studio ("Matra") you agree to these terms.
The service
Matra converts music recordings you provide into chord charts and notation, which you can view, edit, and export. Transcriptions are AI-generated and may be inaccurate — especially on dense mixes. You are responsible for reviewing results before relying on them.
Your content and rights
- You must have the right to upload any recording you import. Do not upload audio you do not own or have permission to process. You represent that you hold the necessary rights.
- You keep ownership of the recordings you upload and the edits you make. We use your audio only to generate your chart and then delete it (see the Privacy Policy).
- Chord symbols, keys, and other musical facts are not owned by anyone. Matra does not reproduce or distribute third-party tabs, arrangements, or sheet music.
Credits, subscriptions, and billing
- Transcription consumes credits. Editing, notation, sargam, and exports are free.
- Subscriptions and credit purchases are billed through Apple. Prices are shown before you buy. Manage or cancel via your Apple account settings; Apple's refund policy applies.
- Free credits (welcome grant and any monthly allowance) have no cash value and may change for new users over time.
Acceptable use
Don't abuse the service: no automated scraping, no attempting to exceed rate/cost limits, no uploading unlawful content, no reverse-engineering or disrupting the service.
Termination
You may delete your account at any time (Settings → Delete account). We may suspend accounts that violate these terms or abuse the service.
Disclaimers
The service is provided "as is" without warranties. To the maximum extent permitted by law, Matra is not liable for indirect or consequential damages, and our total liability is limited to the amount you paid us in the prior 12 months.
Changes
We may update these terms; continued use after changes means you accept them.
