Unauthorized Data Collection
The extension sends the user's spell check text to [domain withheld] via the background's fetch proxy. This domain is not listed in the manifest's host_permissions, nor is it disclosed in the Chrome Web Store privacy policy. The transmitted text may contain sensitive information, making this unauthorized data collection.
Analyst notes
The extension sends user-provided text to a third-party domain ([domain withheld]) not disclosed in the Chrome Web Store privacy policy or listed in the manifest host_permissions. This is unauthorized data collection. No other malicious indicators found; the extension's core spell-checking functionality is otherwise legitimate.
