Terms of use
https://stem-nealvdv.vercel.app/en/terms
Stem is a learning app by Neal Van de Velde (nealvdv), enterprise number BE 0671.938.794. You can reach us at contact@nealvdv.be. More in the legal notice.
The learning path and the first topics of Stem are free, without an account, without ads and without tracking. Your progress stays on your own device.
You can open every topic with Kaft Plus. You take it out on Kaft, not in Stem, and the terms of Kaft Plus apply there, with the prices, cancelling and the right of withdrawal. Stem itself never asks you to pay.
We make the lessons and exercises with care, but a mistake is always possible. If you see one, report it at the bottom of the page with "Spotted a mistake?" or at contact@nealvdv.be. Stem helps you learn and does not replace a teacher or a school.
You may use Stem to learn, at home and in class, and print worksheets for yourself or your pupils. Copying the texts, exercises and drawings to sell them or publish them elsewhere is not allowed without our consent.
We do our best to keep Stem working well and available, but cannot promise it will always work without errors or interruptions. Your rights as a consumer always apply.
How we handle your data is in the privacy statement.
Belgian law applies. For a complaint, write to contact@nealvdv.be; we answer within fourteen days. If we cannot solve it together, you can turn to the Consumer Ombudsman Service.
If these terms change, you see the new date at the top of this page.
