Terms of Service

1. Who we are

Extruse is run by Oleksii Vaschenko, an individual based in Norway. There is no registered company behind it. If one is registered, its name, address and registration number will appear here.

Write to hello@extruse.com about anything here. A reply comes from a person, not a helpdesk.

2. What Extruse is

Extruse is a costing and planning tool for 3D-printing businesses. It works out what a print truly costs, what it earns per machine-hour, and how failures, materials and time affect that.

3. Your account

You can use Extruse without an account, in which case your data stays on your device. If you create one, you are responsible for keeping access to it secure and for everything done through it. Tell us promptly at hello@extruse.com if you think someone else has got in.

You must be at least 16 years old and use Extruse for a business or trade purpose.

4. Plans and payment

Extruse is free today, and the calculation always will be: every cost item and every formula stays free. If paid plans appear, they will cover workshop organisation — inventory, queue, clients — and the terms of any trial, renewal and cancellation will be stated before you pay. Existing users will be told at least 30 days before a price they already pay changes.

5. What the numbers are, and what they are not

Extruse calculates from the figures you enter and the assumptions you choose. Its output is an estimate, not financial, tax, accounting or legal advice.

We work to make the arithmetic honest, to show where every number comes from, and to say plainly when a sample is too small to support a conclusion. But a costing model is only as good as its inputs, and it cannot know your market, your customers or your obligations. Pricing decisions, and their consequences, are yours; we are not liable for business outcomes that follow from using the tool.

The assistant suggests; it does not calculate. When it fills in your workshop from a description, drafts a listing, or tells you what similar items usually sell for, a language model produced that answer — plausibly, which is not the same thing as correctly. It has not seen your market, your photographs or your competitors, and it says so itself. Every figure it proposes is shown to you before anything is saved, the arithmetic that follows uses the figures you confirmed rather than the ones it guessed, and what you publish and what you charge stay your decisions. How this works is set out in section 8 of the Privacy Policy.

6. Your data belongs to you

Everything you record — products, prices, machines, production history — is yours. We claim no ownership, do not sell it and do not use it to train models. We do count things across all workshops to see what to fix next; those counts carry no name and no prices. The rest we process only to run the service for you, as described in our Privacy Policy.

You can export your entire workshop to a file at any time, from inside the app, without asking us. If you close your account, do that first.

Your customers are a separate matter. When you record a client — a name, a phone number, an email — that is personal data about someone who has no agreement with us. You decide what to keep about them and why; we only store it so it reaches your other devices, and we do not read it, share it or use it. By using the clients section you confirm you are entitled to hold those details, and you remain the one who answers to the people in it. How this works in practice is set out in section 4 of the Privacy Policy.

7. Acceptable use

Do not use Extruse to:

• break the law, or help anyone else do so;
• attack, overload or probe the service, or try to reach other people’s data;
• resell or rebrand the service as your own without a written agreement.

We may suspend an account doing these things, and will say why when we can.

8. Availability and liability

We aim to keep Extruse running and correct, but we provide it “as is” and do not guarantee it will be uninterrupted or error-free. We depend on providers such as our hosting and email partners, and outages at their end affect us.

To the extent the law allows, our total liability for any claim is limited to what you paid us in the 12 months before it arose. We are not liable for lost profits, lost business or indirect losses. Nothing here limits liability that cannot legally be limited, including for death, personal injury or fraud.

Keep your own backups. The export function exists for exactly this reason.

9. Ending the agreement

You can stop using Extruse and delete your account at any time; deletion takes effect after seven days, during which you can undo it. We may end the agreement with 30 days notice, or immediately if you seriously break these terms. If we discontinue the service, we will give reasonable notice and time to export your data.

10. Changes to these terms

We may update these terms. For material changes we notify account holders by email before they take effect. Continuing to use Extruse after that means you accept the new version.

11. Governing law

These terms are governed by the law of Norway, and disputes go to its courts. If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you live.
