Terms

The site

The pattern library is free to read, without an account. It is provided as is: the breakdowns are opinions on interface design, not guarantees of any outcome in your own product. designmotionhq may change or remove content at any time.

Buying UX Engine

UX Engine is sold for $79, one-time payment, through Lemon Squeezy, which acts as merchant of record. The sale is concluded with Lemon Squeezy: it issues the invoice, collects any applicable tax and processes refunds, under its own terms. The price shown on this site is the price before any tax Lemon Squeezy adds for your country.

Delivery is immediate: the download and installation instructions are on the page shown after payment and in the confirmation email.

Licence

A purchase gives you a personal, non-exclusive, perpetual licence to install and use the plugin on your own machines, in any project, including commercial ones. What you build with it is yours.

Teams need one seat per developer who uses the plugin; the seat picker on the checkout sets the quantity. The plugin files may not be redistributed, resold, shared outside your seats or published, in whole or in part, including inside another product.

Updates to the current version are included. designmotionhq may release a new major version as a separate product.

30-day refund

30-day money-back guarantee, no questions asked. If the plugin is not for you, one email to support@designmotionhq.com within 30 days of purchase gets you a full refund. No questions, no form. The refund is issued by Lemon Squeezy to the original payment method, and the licence ends with it.

The Blueprint

The Design System Blueprint is free against an email address. Taking it subscribes you to emails about new patterns and designmotionhq tools, which you can leave at any time. The PDF is for your own use and may not be redistributed.

Third-party tools

UX Engine runs inside Claude Code and other agents that read skills. Those tools belong to their owners, are not affiliated with designmotionhq, and change on their own schedule. designmotionhq keeps the plugin working with them as best it can but cannot guarantee compatibility with every future release, nor the output of any model.

Warranty and liability

Beyond the refund above, the site and the plugin are provided as is, without warranty of any kind. To the extent the law allows, designmotionhq is not liable for indirect loss arising from their use. Nothing here limits the statutory rights of consumers.

Internal tools

designmotionhq also operates internal tools that connect to the social media accounts it owns, for analytics and publishing. They are operated by and for designmotionhq only, within each platform's developer policies, and are not offered as a product to the public. Access is granted for our own accounts and can be revoked by us at any time.

These terms are governed by French law. Questions go to support@designmotionhq.com.
