These are the rules for using 4hands and buying it, in plain words. Using the site or paying for it means you agree to them. How we handle your data is in the privacy policy.
4hands is made and run by two people: me, Kosta (@kosta4a), a designer, and Marko Zivanovic (@zivkeey), an engineer. It lives at 4hands.dev. In these terms, “we” means the two of us.
We sell 4hands through our company, 44 Studio LLC (30 N Gould St Ste N, Sheridan, WY 82801, USA). It’s the seller on every order, and charges show on your card statement as “44 STUDIO* 4HANDS”.
Write to us about anything on this page at contact@4hands.dev.
One payment gets you lifetime access to the library: every lesson, demo and agent skill in it today, and every one we add later. Nothing renews, and there’s no subscription.
It’s for one person, on one account. For a team, email contact@4hands.dev with how many seats and we’ll sort it out.
Until the launch, buying 4hands is a pre-order: you pay before it’s out. A free account unlocks the first 2 lessons now, and everything else opens for buyers December 14, 2026. Member cards come on launch day too, not before.
If the launch were ever cancelled, every pre-order would be refunded in full.
The pre-order price is $100, once, until launch day. On launch day it goes up to the list price, $200. Prices are in US dollars, and you pay what checkout shows you.
Stripe takes the payment. Your card details go to Stripe, not to us.
100% of the payment for every pre-order and order, after Stripe’s card fee, goes to Neda. Stripe keeps that fee, 2.9% plus 30 cents on most cards, and the rest is hers. Donations of any amount go through Pokreni život, a registered Serbian humanitarian organisation that runs her fundraiser and pays her treatment bills directly, and never pass through 4hands.
The current goal is $15,000, and it goes up if she needs more. What’s been raised so far is on the donate page.
Pre-orders and orders can be refunded on request: email contact@4hands.dev. You can’t get a refund once you’ve completed at least one category or actively used the skills provided. Donations go through Pokreni život, not 4hands, so we can’t refund them.
Write from the email you paid with, so we can find the payment.
You sign in with Google or with a magic link sent to your email. Sign-in runs through Clerk, and there are no passwords. Keep your email safe: whoever can read it can sign in as you.
You can delete your account any time from your account page. That removes your card and your progress, and it can’t be undone. It doesn’t refund a purchase by itself, so if you want your money back, email us first.
The lessons and demos are ours. Use them for your own work, and your team’s if you bought seats for it. Don’t resell them, republish them or share your account so others can read them.
Agent skills made by other people keep their own licences.
Don’t try to break the site, scrape it, overload it or get into lessons you haven’t paid for, and don’t use it to hurt anyone. If you do, we can close your account.
Found a hole? Email contact@4hands.dev. We’d rather hear it from you.
4hands is made by two people and provided as it is. We do our best to keep it up and right, but we can’t promise it never goes down or never has a mistake in it.
As far as the law allows, we aren’t liable for more than what you paid us.
When these terms change, the date at the top changes with them. For big changes, we’ll also email everyone who has bought 4hands.
Email contact@4hands.dev. For what we collect and why, read the privacy policy.
