<rewrite>
<rules>
<rule name="Redirect to Landing Page" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAny">
<add input="{HTTP_Host}" pattern="www.dev.MyWebpage.com/MCPrivacyNotice" negate="true" />
</conditions>
<action type="Redirect" url="https://www.myWebPage.com" />
</rule>
</rules>
</rewrite>

Answer 1

As you described, so you need to redirect when
Domain is www.dev.MyWebpage.com
Request uri is /MCPrivacyNotice
So I think this may be your answer
<rule name="Redirect to Landing Page" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{HTTP_HOST}" pattern="www.dev.MyWebpage.com" />
<add input="{REQUEST_URI}" pattern="/MCPrivacyNotice" negate="true" />
</conditions>
<action type="Redirect" url="myWebPage.com" />
</rule>
Note that logicalGrouping="MatchAll" to match all condition. In your question and your update you used logicalGrouping="MatchAny" that means every request from domain www.dev.MyWebpage.com will be redirected
One more thing, /MCPrivacyNotice is {REQUEST_URI} or PATH_INFO not QUERY_STRING you should choose the right module. Check this for detail https://learn.microsoft.com/en-us/iis/extensions/url-rewrite-module/url-rewrite-module-configuration-reference
Hope this helps
