Terms of use

Last updated 2026. Draft.

Using Voictrum

You are welcome to use Voictrum in your browser: play the Choir, the Studio, the Lab, Learn and Teach, and make, record and download your own performances for your own purposes, including sharing the recordings you make.

What you may not do

Voictrum (its program code, engine, voices, data, texts as arranged here, images and design) is © 2026 Voictrum, all rights reserved. Without written permission you may not:

• copy, download or save the app or its code (the scripts, the WebAssembly engine, the data files) to run, study for reuse or rebuild elsewhere;
• re-host, mirror, frame or redistribute the app or any part of it, or offer it as part of another product or service;
• scrape the site, or access it with automated tools beyond ordinary browsing, or put excessive load on it;
• modify, decompile or reverse-engineer the app, except where the law allows it regardless of these terms;
• remove or hide the copyright and licence notices.

Some parts of Voictrum are other people's work, used under their own licences; those licences still apply to those parts. See the Notices.

What you send us

Some features send things to the site:

• Share links. Share stores the arrangement or take you share and gives it a link; anyone with the link can open it, and stored shares are not edited or removed by you afterwards.
• Teach votes. Your votes and fixes are kept with a random id made in your browser, not your name; they are used to teach the voices to sound more natural, and counts of them are shown to everyone.
• Lab reports and rule sets. These are held for the owner's review; an approved rule set is listed for everyone.

Your address is used only, hashed, to limit how often things can be sent, and is not stored. By sending something, you confirm you may share it, and you let Voictrum keep, show and use it for these purposes. Do not send anything personal or anything you do not have the right to share.

Things you only make in your browser (projects, takes, recordings) stay on your device unless you share them.

No warranty

Voictrum is provided as it is, free of charge, without any warranty: it may be wrong, change, or stop working at any time. To the extent the law allows, Voictrum is not liable for any loss or damage from using it.

Changes

These terms may change; the version on this page is the one that applies.
