Usage Analytics Events

Window Resize Manager uses explicit, privacy-safe PostHog usage analytics in both the external Chrome Web Store build and the internal development build. Every event includes build_variant so internal and external usage can be segmented.

Analytics are cookieless and memory-only. There is no user-facing setting to disable analytics, and the implementation does not use autocapture, session replay, surveys, heatmaps, pageview/pageleave capture, persistent identifiers, cookies, or website storage.

PostHog endpoint: https://eu.i.posthog.com

Privacy Exclusions

Analytics events must never include page content, selected text, tab titles, full URLs, website cookies, website localStorage, account data, preset names, exact custom dimensions, raw error messages, or stable personal identifiers.

All event properties are enum values, booleans, or low-cardinality buckets.

Every implemented event includes this common property:

• build_variant: external, internal
