# Copyright and reuse **The words, the design and the code of this site are © Engineer ApS.** So are the brand mark, the cog, the mascot in every pose, the portrait and the photographs of our Copenhagen office. Most of what you might want to do with them needs no permission at all, and this page says which uses do. ## What you may do without asking - **Link to any page**, from anywhere, with any words you like. - **Quote from it.** Danish copyright law lets anyone quote a published work in accordance with proper usage and to the extent the purpose requires (section 22 of the Copyright Act, _ophavsretsloven_), naming the source as proper usage asks. A link back to the page you quote names it best, and we are glad to see it used. - **Index it, and let AI read it.** Search engines and AI systems may crawl these pages, index them, answer questions from them and train on them. The site's [robots.txt](/robots.txt) says so in a form machines read: `Content-Signal: search=yes, ai-input=yes, ai-train=yes`. ## What needs our permission first - republishing a whole page, or a substantial part of one; - using the brand mark, the cog or the mascot; - using the portrait or the photographs of our office. Write to [welcome@engineer.company](mailto:welcome@engineer.company) and say what you have in mind. That is what "All rights reserved" at the foot of every page means. ## What is borrowed - **Typefaces, icons and the photographed walls** belong to their makers and are used under their licences or with their permission. The [credits](/credits/) page names each one, who made it and the terms it comes under. - **The photographs in the bands across these pages** come from [Pixabay](https://pixabay.com/), under the [Pixabay Content License](https://pixabay.com/service/license-summary/), and each names its photographer to a screen reader.
