Terms of service

Last updated 10 September 2026

1. Who you are agreeing with

These terms are between you and Emanuel Amaral, who runs HIIT for Musicians ("the app"). By creating an account you accept them.

2. What this app is

HIIT for Musicians is a tool. The importing, cropping, arranging, annotating and routine-building all run automatically, on the material you choose, when you tell them to. We are not a publisher, an editor, a curator or a distributor of music, and we do not select, review or approve what anybody uploads.

Providing tools that can crop or combine a page is not encouragement to do that to work you have no right to. What you put into the app, and what you do with it there, is your decision and your responsibility.

3. Your account

• You need a verified email address, or a Google account, to sign in.
• One account per person. Keep your password to yourself.
• You must be at least 13 years old. Under 16, please have a parent, guardian or teacher agree to these terms on your behalf.
• Tell us if you think someone else has got into your account.

4. What it costs

Nothing. The app is currently free and in testing, and contains no payments, subscriptions or purchases of any kind. If that ever changes we will say so clearly, with the price, before asking anyone for anything — and existing data will not be held hostage to it.

5. Music you upload

This is the part that matters most, so it is worth being direct about it.

Keeping it for yourself

Photographing or scanning a page from a method book you own, cropping the bars you are working on, and practising from it in the app is what the app is for. That material stays private to your account. We do not inspect it and we do not share it.

Making it public

Marking an exercise public publishes it to every other user of the app. Only do that with music you wrote yourself, music in the public domain, or music you otherwise have the right to distribute. Publishing an excerpt from a copyrighted method book, edition or arrangement without permission is not something we can allow, and by publishing anything you confirm you have the right to.

What we do about it

• You keep ownership of everything you upload. We claim no rights over your music beyond storing it and showing it to you — and, if you make it public, to other users.
• If a rights holder tells us something published in the app infringes their copyright, we will remove it — see section 9.
• Repeatedly publishing infringing material will cost you your account.

6. Things not to do

• Do not upload anything unlawful, or anything that is not sheet music, notation or practice material.
• Do not use the app to distribute whole books, or to build a library for others to download.
• Do not attack the service, scrape it, or try to reach other people's accounts or private exercises.
• Do not automate the API in a way that degrades it for other people. Rate limits exist; do not work around them.

7. Availability, and that this is a test

The app is in active development and distributed to a small group of testers. Things will break, features will change, and there will be downtime. We aim to keep your data safe through all of that, but we cannot promise uninterrupted service and you should not treat the app as the only copy of anything you care about. Keep your original scores and files.

8. Ending it

You can delete your account at any time, from within the app — see deleting your account. It takes effect immediately and removes your exercises and practice history with it.

We may suspend or close an account that breaks these terms, particularly section 5 or 6. Except where the breach is serious or unlawful, we will tell you what the problem is and give you a chance to put it right first.

9. Reporting an infringement

If you are a rights holder — a composer, an editor, a publisher, or someone acting for one — and you believe something published in the app infringes your copyright, tell us and we will act on it promptly. Send it to [email protected].

So that we can act rather than write back asking, please include:

• What the protected work is, and enough to identify it — title, composer, edition or ISMN.
• Where the infringing material is in the app: the exercise name, and its link or identifier if you have one.
• Who you are, how to reach you, and on whose behalf you are writing.
• A statement that you believe in good faith that the use is not authorised by the rights holder or the law.

We will look at every report that arrives, remove or disable access to material we find infringing, and tell both you and the person who posted it what we did and why. Somebody who thinks we removed their work wrongly can say so, and we will look again. An account that attracts repeated, well-founded reports will be closed.

We do not review uploads before they appear — see section 2 — so a report is usually the first we know of a problem. That is why this route exists and why we would rather hear from you than from a lawyer.

10. If your upload causes us a problem

If somebody brings a claim against us because of material you uploaded or published — a copyright claim, most likely — you agree to cover what that claim reasonably costs us to deal with, including legal fees.

Two limits on that, because a clause like this is easy to overstate. It only reaches claims that actually arise from what you put in, not from how we built or ran the app. And if you are a consumer, it applies only so far as consumer law in your country allows — in most of the EU that is considerably less far than the sentence above suggests, and we are not trying to get around it.

11. Liability

The app is provided as it is. To the extent the law allows, we are not liable for indirect or consequential loss, for lost data where you had no other copy, or for anything arising from your use of material you did not have the right to upload. Nothing here limits liability that cannot lawfully be limited — including for death or personal injury caused by negligence, or for fraud.

If you are a consumer, your statutory rights are unaffected by anything in these terms.

12. Changes to these terms

If we change these terms in a way that affects you, the date at the top changes and we will tell you in the app before the change takes effect. Continuing to use the app after that means you accept the new version; if you do not, delete your account.

13. Law

These terms are governed by the law of Portugal, and its courts have jurisdiction. If you are a consumer resident elsewhere in the EU, you keep the protection of your own country's mandatory consumer law.
