Is Duration for Google Tasks safe?

Low risk

Duration for Google Tasks sends pageview and autocapture telemetry from Google Calendar and Tasks pages to PostHog.

Duration for Google Tasks initializes PostHog analytics when its content script runs on Google Calendar and Google Tasks pages. The analytics configuration enables pageview capture and autocapture, which can include the page URL, page title, and DOM content, and sends those events to PostHog's EU endpoint while disabling session recording.
