In-depth safety analysis
The extension requests host access to mail.google.com, which lets it integrate directly with the Gmail interface to add read receipts, split inbox, hotkeys, and reminders. Supporting permissions like storage, identity, background, and gcm are standard for a Gmail productivity tool that needs to save settings, authenticate with your Google account, run in the background, and deliver notifications. The declarativeNetRequestWithHostAccess permission likely supports read receipt tracking by managing network requests on Gmail.
For any extension that interacts with email, remember it can access sensitive message content. The developer declares it collects user activity data but states data is not sold or used for unrelated purposes. Gmail enhancers are sometimes cloned by malicious actors, so it is wise to verify you are installing the authentic extension and to review the permissions you grant.
The safety score is high at 90.8 out of 100. Community Reputation is perfect, reflecting strong user trust, while Publisher & Identity is the weakest dimension, which may indicate a smaller or less publicly verified developer—a common profile for niche productivity tools.
