Terms of use

Who we are

ReDo is run by ReDo Tech ApS, a Danish company: "we" and "us" on this page. These terms apply between you and us whenever you use ReDo: this site, the Playground and the Inventory. Write to admin@redo.pro about anything on this page.

Accepting these terms

You accept these terms, and our privacy notice, when you make your account: the first time you sign in, we show you what they say in short and ask you to accept them. When they change, we ask again before you go on. You can use the Playground without an account, and these terms still apply to that use. This is version 1, of 9 October 2026.

The service

ReDo is an editor for building with real parts, the Inventory of those parts, and the site around them. It is in beta: it works, but it is still being built, and it will change. Using it is free. Paid plans will come later, as our pricing page shows; nothing charges you until you choose one, and you will see what a plan costs and what it includes before you do.

Your account

You can use the Playground without an account. An account keeps your work and lets you share it.

• An account is for one person. Keep the email address you sign in with, or your Google or GitHub account, to yourself: whoever can read it can sign in as you.
• You must be 15 or over to have an account, or have a parent or guardian set it up with you, as our privacy notice says.
• What is done with your account is your responsibility. If you think someone else has used it, tell us.

Using ReDo fairly

• Don't use ReDo for anything unlawful, or to share what isn't yours to share.
• Don't attack ReDo or overload it: no breaking in, no flooding it with requests, no getting round its limits. If you find a weakness, tell us, as our security page explains.
• Don't copy the Inventory in bulk, by scraping its pages or any other way, beyond what our public API allows. Downloading the parts you need, as their licences allow, is fine.
• Don't run ReDo's Playground or its engine as a service for others.

If you find something on ReDo that you think is unlawful or breaks these terms, write to admin@redo.pro.

Your content

What you make with ReDo is yours: your projects, the parts you design or upload, and their pictures and descriptions.

• You give us the rights it takes to keep it and show it as you choose: to store and copy it, backups included, to process it (to build it, convert it and draw its pictures), and to show it to the people you choose. They last as long as we hold it for you.
• No other user sees your private work. What you make public, anyone can see: anyone can open a public project and clone it into a copy of their own, and a part you make public is shared under the licence you choose for it, or none, when you keep every right.
• Our team may open your projects and parts, private ones included: to run ReDo, to answer a problem you report, to stop abuse, and to learn what to make better. Never other users. Our privacy notice says why and for how long.
• Whether our team may also see how you use ReDo, like the pages you open and what you search for, is your choice, on the card every visitor answers once, as our privacy notice explains.
• We don't train AI on your work, and we don't sell it.

Parts and their licences

Every part in the Inventory comes with a licence, named on its page, and the licence goes with the part wherever you take it: into the projects you share and the files you export. Credit and share as each part's licence asks.

• A part under its maker's own terms, rather than an open licence, is in ReDo for you to build with. Its CAD is the maker's to give: get it from the maker's own link on the part's page.
• The parts we drew ourselves are under CC BY-SA 4.0, except that using them in a design, or in a file you export from one, doesn't make your design share-alike.
• Our OpenSCAD library, the code those parts are written with, is under the MIT licence.

Our credits list every part library and its licence.

The AI assistant

The Playground's assistant answers with an AI model, and it can be wrong. Check what it suggests (the parts, sizes and wiring) before you build anything that matters. What you ask it goes to Anthropic, whose model writes the reply, as our privacy notice explains.

We keep your conversations with the assistant, what you write, what it does in your project and what it answers, with your account. Our privacy notice says why and for how long.

ReDo's own code

The Playground, its geometry engine ReDoCore and the rest of ReDo's software are ours. The open-source software inside them keeps its own licence, listed on our credits page. Where a licence gives you a right, as Open CASCADE's LGPL lets you change that library and reverse engineer the Playground to debug your changes, nothing in these terms takes it away.

Availability and changes

ReDo is in beta. It may be unavailable at times, and our status page says whether it is working right now. Its features will change, and we may stop offering part of it, or all of it. When these terms change, we tell you before the new terms apply and ask you to accept them, and the date at the top of this page changes.

Liability

We build ReDo with care, but while it is in beta it comes as it is. As far as Danish law allows, we are not liable for any loss that comes from using ReDo, from being unable to use it, or from what you build with it. Nothing here limits a liability the law doesn't let us limit, and if you use ReDo as a consumer, you keep every right that consumer law gives you.

Ending

You can stop using ReDo whenever you like, and delete your account at any time under Account Settings → Delete account, as our privacy notice describes. We may suspend an account that breaks these terms, and take down what it has made public; when we do, we tell you why.

Law

Danish law governs these terms. If you are a consumer living in another country, you also keep the protection its mandatory law gives you.
