Copyright and takedown

How we use other people's work

System Design Atlas is a curated index. For videos, articles, repositories and courses we show our own short description, the creator's name and a link to the original. We do not copy their text, diagrams or videos. YouTube videos are shown with YouTube's official player. Where a thumbnail is shown it is either the source's own preview image or a generated placeholder.

Case studies, roadmaps, quizzes and articles written for this site are original summaries in our own words. Where we host material that someone else licensed to us (for example under Creative Commons), we show its license and credit.

Ask for a correction or removal

If you own something we link to and want it credited differently, corrected or removed, contact us at [email protected]. Please include the page URL, what you want changed, and that you are the owner or their authorised agent. We aim to act within 7 days, and remove the entry first if there is any doubt.

For a formal copyright notice, include your contact details, a description of the work, the URL of the page concerned, and a statement that you believe in good faith the use is not authorised.
