Is 30 Seconds of Knowledge safe?

Low risk

30 Seconds of Knowledge sends page-view telemetry from its new tab and UI pages to Google Analytics with persistent IDs.

When you open its new tab, popup, settings, snippet list, favorites, or a specific snippet page, it creates client and session IDs in extension storage and posts a Google Analytics event. The event includes the extension page URL, page title, and a snippet id from the page query string when present.
