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

rate_extension_clicked

Trigger: a user selects Rate extension in the popup feedback card.

The event does not include a rating value or Chrome Web Store URL.

feedback_clicked

Trigger: a user selects Send feedback in the popup feedback card.

Allowed properties: none beyond the common build_variant property.

The event does not include an email address, subject, body, or destination URL.

extension_cross_promo_viewed

Trigger: the More tools footer becomes at least 50% visible in the popup. The event is emitted once per recommended extension during that popup lifetime. If visibility observation is unavailable, no impression is recorded.

Allowed properties:

• source_extension: window_size_manager
• target_extension: screenshot_capture_studio, posthog_debugger
• placement: popup_footer

extension_cross_promo_clicked

Trigger: a user selects one of the More tools extension links.

• source_extension: window_size_manager
• target_extension: screenshot_capture_studio, posthog_debugger
• placement: popup_footer

Neither event includes a Chrome Web Store URL, page URL, or stable identifier.

Feedback Card Success Metric

Evaluate the card by comparing rate_extension_clicked and feedback_clicked counts with popup_opened counts for the same build variant. The events are aggregate product signals only; they cannot identify whether a particular user submitted a rating or sent an email.

Cross-Promotion Success Metric

Compare extension_cross_promo_clicked with extension_cross_promo_viewed for each target_extension and build_variant. This measures aggregate discovery-to-click conversion without identifying users or recording destination URLs.

Not Implemented Yet

The presets_imported, presets_exported, and shortcut_invoked events are reserved for future product flows. They are not emitted by the current popup.
