What our analysis found

Calendly Browser Extension, used by 700,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites and can inject scripts into pages. It comes from a trusted publisher and was last updated in August 2026.

Analyst notes

The extension is a legitimate meeting scheduling tool from a well-known publisher. All network requests target Calendly-owned domains; analytics with Segment is disclosed under 'User activity' in CWS data collection. Broad permissions are justified for cross-platform integrations (Gmail, Google Calendar, LinkedIn, Gong). Code is standard webpack output, not obfuscation. No unauthorized data exfiltration, remote code execution, or credential theft found.
