Do I have to cite the website I used to draw a circuit?
<p>I need to draw some boolean circuits. If I use a web-app like <a href="https://logic.ly" rel="nofollow noreferrer">https://logic.ly/demo/</a>, do I need to cite or refer to them? Or somehow attribute that the icons are not owned by me?</p>
<p>To put it explicitly: If I draw a circuit with such an app and export an image or do a screenshot of that circuit, and I publish this image in a document, is there any other action needed in order for this to be legal?</p>
<p>(something like: image was created using <a href="https://logic.ly" rel="nofollow noreferrer">https://logic.ly</a>)</p>
