Top Risks

• Free-webmail dev (bigdeveloper44@gmail.com) + no developer name + no business domain = high anonymity risk.
• Privacy policy is Google's generic account policy — not scoped to this extension; admits broad data collection and 3rd-party sharing.
• External JS host 'chromecrxstore.com' is unrecognized/suspicious; HK geo-diversity adds concern.
• Brand impersonation: 'reddit' mentioned in description; developer not confirmed owner.
• install_url_hijack flagged true; low install count (24) with multi-search-engine host access across 9 engines.
