Widgets which let you ask for support (live chat) should be shown on the site even if tracking info is disabled. For example: Intercom.
We have a nifty live chat widget which allows you to ask for help in the site. We do collect tracking info within a site, which is why I’m assuming it doesn’t show, but this is usually to build help guides, walkthroughs, but not for advertising purposes.
I think the question boils down to: How do you disable tracking but allow live chat widgets to show?
I do think allowing live chat platforms to show is critical for a sass platform!
Full disclosure: I work at Intercom
