Privacy, diagnostics and icon licensing
Two cards at the bottom of Settings → General cover what the platform is (and isn't) allowed to tell home about your usage, and where the icon/logo licensing comes from.
Privacy & Diagnostics: anonymous usage diagnostics are on by default to help fix bugs, and can be switched off any time with no change to how the platform runs. What is and isn't collected is spelled out right here, not buried in a policy doc.
Vendor Logos & Trademarks is upfront about where every device icon comes from (Simple Icons, Devicon) and that vendor logos are used for identification only, not endorsement.
Every account controls its own diagnostics opt-out - no admin needed. See "Choosing Web vs. Desktop console mode" for the card just above these two.
