From a purely legal standpoint, is it allowed to embed Google apps (like docs) in your website using iframes?
<p>So, some time ago Google removed the <code>X-Frame-Options</code> header from Docs / Sheets / ...</p>
<p>Does that mean, from a purely legal standpoint, that it is allowed to embed their applications on my website via iframes or any other method? If so, do I have to put a disclaimer somewhere that the embedded app is from Google?
Where would I find information about that? I looked up Google's Terms of Service (<a href="https://policies.google.com/terms?hl=en-US" rel="nofollow noreferrer">Google ToS</a>), but there's nothing to be found there.</p>
<p>Can I, to further extend that question a bit, alter the appearance by overriding certain CSS elements? Again, not technically, but legally. Where would I find information about that? Say, I wanted to change the color of the share button from whatever it is to green. Allowed or not? Say I wanted to hide the share button. Allowed?</p>
<p>I'm asking this question because it is very important to me that I do not violate Google's Terms of Service or any other IP rights for that matter.</p>

<p>What copyright or trademark law permits and what Google's terms of service permit may well not be the same thing. It is not &quot;illegal&quot; to violate the ToS unless they form a binding contract, which often they will not. Even when they do, unless some cognizable harm is done, a violation of the TOS is probably not enforceable by suit or in any other way.</p>
<p>Embedding via an Iframe simply points the browser to another site, and probably is not legally different from including a clickable link.</p>
<p>Using CSS to alter the display <strong>might</strong> be considered to be creating a derivative work, and thus to be a copyright infringement if done without permission.</p>
<p>Somce the linked document says:  &quot;<em>Don’t remove, obscure, or alter any of our branding, logos, or legal notices.</em>&quot; making any such change woule violate the terms of the ToS, although this might not be an enforceable restriction. It is also IMO doubtful whether a &quot;share&quot; button constitutes part, of the &quot;<em>branding, logos, or legal notices.</em>&quot;</p>
