<h3>External Services</h3>
IdleFrame Screensaver can load embedded videos from YouTube or Vimeo when those sources are selected.
When a page uses a YouTube screensaver, the visitor’s browser connects to YouTube/Google services to load the embedded player and video. YouTube or Google may process data according to their terms and privacy policy:
<ul>
<li>https://www.youtube.com/t/terms</li>
<li>https://policies.google.com/privacy</li>
</ul>
When a page uses a Vimeo screensaver, the visitor’s browser connects to Vimeo services to load the embedded player and video. Vimeo may process data according to its terms and privacy policy:
<ul>
<li>https://vimeo.com/terms</li>
<li>https://vimeo.com/privacy</li>
</ul>
Local video and image sources use media from this WordPress site and do not load YouTube or Vimeo services.
