Is ExtractCSS safe?

Clean risk

ExtractCSS sends page URLs, referrers, and a persistent client identifier to PostHog during extension use.

When you open the extension overlay or start an extraction, ExtractCSS records usage events through PostHog. Those events include the active page URL or referrer, a persistent client identifier stored by the extension, and extraction details such as output format and whether the whole page is selected.
