Terms & conditions

Doublesharp is operated by an individual UK-based operator trading as Doublesharp. For any question about these terms, email hello@doublesharp.co.uk.

We don’t set an age range. Grade 5 theory is the same paper whoever sits it, and the people who need it are as likely to be a nine-year-old racing ahead or an adult coming back to music as the twelve-year-old the app was first written for.

The account holder must be 18 or older. There are two kinds of learner profile on an account:

• Your own. No invite and no PIN: you are already signed in, and nobody else can see it.
• Someone else’s. Set up and supervised by you. You create the profile, and they join via an invite link you send them and a code they choose. By creating one you confirm you are that person’s parent, legal guardian or authorised instrumental teacher, and that you have the right to set up an account on their behalf.

Anyone under 18 uses Doublesharp through an adult’s account. That adult can see, export or delete everything held about them at any time.

Doublesharp is in open beta. The free tier is currently the only tier. We may change the scope, features, pricing, grades covered, or availability at any time. We’ll give reasonable notice (account email) before any change that affects your existing data or that introduces a charge.

The free tier is not crippled and will stay free even after a paid tier launches.

By using Doublesharp, you and any learner on your account agree:

• Not to share account or invite credentials with anyone who isn’t the intended user.
• Not to use the service to harass, defame, or harm anyone.
• Not to attempt to scrape, copy, redistribute, or resell the question bank, app code, or any other content. The bank is the result of a lot of human + LLM editorial work; if you want to use it commercially, email us first.
• Not to attempt to bypass authentication, the separation between one learner and another, or the admin role gate.

We may suspend or close any account that breaches these rules. We’ll email you first if we possibly can.

What we collect, why, and how to delete it is covered in full in the privacy policy. Short version: minimum data, no third-party trackers, EU-hosted, ask us to delete anything any time.

You can soft-delete a learner profile (with a 30-day restore window) or hard-delete your whole adult account at any time from the dashboard.

The Doublesharp app, brand, and question bank are the property of the operator. We grant the adult account a personal, non-exclusive, non-transferable, revocable licence to use them for the purpose of practising at home with their own children.

References to ABRSM grades and the ABRSM theory syllabus describe alignment only, as explained above. ABRSM is a trademark of its owner and is used here in a descriptive, non-affiliated sense only.

To the maximum extent permitted by UK law: Doublesharp is provided “as is”. We make no warranties, express or implied, about its fitness for any particular purpose, including any educational or exam-preparation purpose.

We are not liable for any loss or damage arising from decisions made on the basis of the app’s output. Nothing in these terms excludes or limits liability for anything we cannot lawfully exclude (death or personal injury caused by negligence, fraud, etc.).

These terms are governed by the laws of England & Wales. Disputes will be heard in the courts of England & Wales unless local consumer-protection law gives you a different right that you choose to exercise.

If we change these terms in any material way, we’ll email account holders, bump the “last updated” date at the top, and add a short summary of what changed. Continued use after that update constitutes acceptance.
