As a browser extension with write access to text fields across all websites, Compose AI has elevated data exposure considerations compared to standalone tools: (1) Chrome extension permissions typically include reading and writing content on pages you visit – users should review exactly what permissions are granted at installation; (2) keylogging risk is inherent to any typing-aware extension, though Compose AI does not market this functionality; (3) no documented security incidents found; (4) the free tier creates a large user base whose typing behaviour data has commercial value. For users handling confidential or regulated information, browser extensions with broad permissions represent a specific risk category.

Confidence label: Probable – privacy considerations based on Chrome extension permission model; specific data handling practices not independently verified.
