The terms, short and clear.

Struq is a trade name of Roy Heilbron, based in the Netherlands. Questions about your account, Pro or the MCP go to [email protected].

Struq is a free, open-source design skill for AI coding tools, with Struq Icons, a photo library, a library of palettes, type pairings and design systems, and the Struq MCP that hands your AI tool the building blocks. You can read the site, install the skill and browse the library without an account. With an account you keep items and recipes in your vault and connect the MCP. Struq Pro gives access to the full library and the building steps through the MCP.

Struq supplies direction, rules and building blocks. What your AI tool builds with them, and whether that works in your project, stays under your own control.

The Struq skill and Struq Icons are open source under the MIT licence. You may use them for any site, your own or a client’s, change them and pass them on, as long as the licence notice stays with the code. The licence also says they come as they are, without warranty. Read it beside the skill’s source and with the 182 icons.

The photos in the photo library are CC0: free to use for anything, without credit.

These licences are wider than the rule for the library below, and for these parts they apply instead.

You may use anything you find in Struq in your own websites and your clients’ websites, commercially too. What you may not do: copy the library, or large parts of it, to set up your own collection or a competing service, or harvest the site or the MCP automatically.

You are responsible for what happens with your account. Do not share your sign-in with others. If you notice that someone else has access, write to [email protected] straight away.

You can have your account deleted through [email protected]. What happens to your data is in the privacy policy.

Pro is a subscription per month or per year, at the price shown before you pay. Payments run through Stripe; Struq never sees your card details.

You can cancel at any time. You keep Pro until the end of the period you have already paid for, and after that the subscription does not renew. If we change a price, you hear about it in advance, and the new price applies only from a following period.

With the Struq MCP, your own AI tool, such as Claude or Cursor, gets access to your Struq account. When you connect it, you choose what the tool may do: only read, or also save items and make recipes. If you revoke the connection in your settings, access stops at once.

What your AI tool does with the data it gets from Struq falls under that tool’s own terms. Struq sends only what the tool asks for and what belongs to your plan.

We keep Struq running as well as we can, but we cannot promise it always works without interruption. Struq is not liable for indirect loss, such as missed revenue or lost work. Where Struq is liable after all, it is never for more than you paid for Pro in the twelve months before.

None of this limits what the law guarantees you as a consumer in any case.

If these terms change on a point that matters to you, we tell you in advance. This page always shows the current version. Dutch law applies to these terms.
