Terms of Service

Last updated: 20 July 2026

These Terms govern your use of Trouble Clef (the "Service"), operated by Harry Anastasiou ("we", "us"). By creating an account you agree to these Terms and to our Privacy Policy.

1. The Service

Trouble Clef lets you upload sheet music, transpose it to a different key, recognise chords from it, build blank manuscript/structure sheets, and create chord-only lead sheets (either by importing your own iReal Pro exports or typing chords in by hand), organised into a personal library and setlists.

Transposition and chord recognition are AI-assisted. They are not guaranteed to be accurate — always review the result before relying on it in performance.

2. Accounts

  • You must provide a real, working email address and keep your password confidential.
  • You're responsible for all activity under your account.
  • You can sign in with a password or with Google. If you use both against the same email, they access the same account.
  • You can permanently delete your account and everything in it (scores, setlists, lead sheets) at any time from Settings. This cannot be undone.

3. Your content and copyright

You keep ownership of everything you upload or create. By uploading a score or importing a chart, you confirm that you own it, are licensed to use it, or otherwise have the right to have it transposed/processed for your own personal use.

  • We don't review or pre-screen uploaded content, and we don't claim any ownership over it.
  • We never bundle, redistribute, or ship anyone else's copyrighted sheet music or chord chart libraries as part of the Service — Trouble Clef only ever processes files you personally bring in.
  • If you believe content on the Service infringes your copyright, contact us at support@trouble-clef.com and we'll investigate.

4. Subscriptions and billing

Trouble Clef has a free tier and a paid subscription ("Pro"):

  • Free — unlimited scores, setlists, and lead sheets; up to 1 transposition, 1 chord recognition, and 3 blank structure sheets per calendar month.
  • Pro — £4.99/month or £49.99/year, billed in advance, removing all three monthly limits. Payment is processed by Stripe; we never see or store your card details.

Pro subscriptions renew automatically at the end of each billing period unless cancelled beforehand. You can cancel any time from Settings → Billing → Manage subscription — cancelling stops future renewals but doesn't refund the current period (see Refunds below). Prices may change with notice; continuing to use Pro after a price change takes effect means you accept the new price at your next renewal.

5. Refunds

Because Pro gives immediate, unlimited access from the moment of payment, subscription charges are generally non-refundable once a billing period has started. If you believe you were charged in error, or you're a consumer entitled to a statutory cooling-off/cancellation right under the law of your country of residence, contact us at billing@trouble-clef.com and we'll deal with it fairly on a case-by-case basis.

6. Acceptable use

You agree not to:

  • Use the Service for any content you don't have the right to use;
  • Attempt to circumvent the free-tier limits, rate limits, or account restrictions;
  • Attempt to access another account's data;
  • Use the Service to build a competing product by scraping or bulk-extracting data.

7. Availability and changes

We don't guarantee the Service will be uninterrupted or error-free. Features may be added, changed, or removed over time. We'll try to give notice of anything that materially reduces what your subscription includes.

8. Liability

The Service is provided "as is". To the fullest extent the law allows, we aren't liable for indirect or consequential losses, or for inaccuracies in AI-assisted transposition or chord recognition. Nothing in these Terms limits liability that can't be limited by law (for example, for fraud or death/personal injury caused by negligence).

9. Termination

You can stop using the Service and delete your account at any time. We may suspend or terminate an account that breaches these Terms, with notice where reasonably possible.

10. Governing law

These Terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute — [CONFIRM: adjust if you incorporate elsewhere or want a different jurisdiction].

11. Changes to these Terms

We may update these Terms from time to time. Material changes will be flagged in the app or by email before they take effect.
