Terms of use
Last updated: 26 September 2026.
These terms govern the use of NodaLab: what you put on it, what you grant the people you share it with, and what the admins may do. Accepting them is the condition for holding an account.
The service
NodaLab is a free, non-commercial service for learning music theory, published by {publisher} and hosted by {host}. It is in a test phase: it may change, be interrupted or come to an end, and nothing it keeps is guaranteed. The accounts opened during the test phase, and what they hold, may be erased when the site opens to the public.
Your account
An account is opened on the sign-up page or on an invitation link, once the link mailed to its address has been followed. You give a true name and address, keep your password to yourself, and answer for what is done from your account. An account is personal. Under fifteen, a parent's consent is needed.
What you put online
NodaLab hosts what you write and upload to it: projects and collections, pictures, messages, MIDI files, theory definitions (voicings, scale types, chord types). You remain its author, and you warrant that you have the right to put it online. You allow the publisher to keep it, back it up and show it to the people you chose, only as far as the service needs to run. This permission ends when you delete the content, except in the database backups, which are overwritten within a few weeks.
Sharing, and what you grant
Sharing a project, a collection, a MIDI file, a picture or a theory definition — with named accounts, a group, or every account on the site — grants each person who receives it a free, non-exclusive licence, for the whole duration of the rights: to open and play it, copy it into their own account and change that copy, use it as a module and make it their own (fork it), take up your theory definitions, and export what they make of it (MIDI, audio, print), for personal or teaching use, with no commercial purpose. A picture shown by a shared project is seen by everyone who may open it. Stopping a share, or deleting, prevents any new copy but does not take back those already made. Nobody presents as their own what somebody else wrote.
What is forbidden
Putting online or sharing what is unlawful, hateful, harassing, violent or pornographic; what exposes somebody's private life; somebody else's work — a score, a recording, a MIDI file — without the right to; advertising or bulk messages. And also: getting into somebody else's account, getting round the service's limits (quotas, sending rates), or disrupting it.
Reporting content
Content that seems to you to break these terms is reported with the Report button shown beside it or, without an account, by writing to {contact}. As a host, NodaLab does not check content before it goes online; it examines every report and acts promptly on what is manifestly unlawful.
Removal of content
To uphold these terms and the law, an admin can open any content stored here, private content included, and remove a picture, a project, a message, a MIDI file or a theory definition. Every removal carries a reason, mailed to its owner. Removed content is gone for good. To contest it, answer that mail or write to {contact}.
Deleting an account
You can delete your account at any time from your account page: everything it holds is removed, except the copies others have already made of it (section 4). On a serious or repeated breach of these terms, an admin may delete an account with everything it holds; the reason is mailed to the account's address, and can be contested in the same way.
Liability
Everyone answers for what they put online. The publisher answers for the service within the limits the law sets for a host, and not for content lost during the test phase: keep a copy of what matters to you (that is what the MIDI export is for).
Changes to these terms
These terms may change. The version in force is always the one on this page, dated at the top. Going on using the service after a change means accepting it; otherwise, you can delete your account.
Governing law
These terms are governed by French law. In a disagreement, write to {contact} first; failing an agreement, the French courts have jurisdiction, without prejudice to the rules protecting consumers.
