Is Smart Converter safe?

Clean risk

Smart Converter identifies analytics users to Amplitude with their Chrome profile email and a stored device ID.

The extension requests identity.email and, in the background service worker, reads the Chrome profile email when no analytics user ID is stored. It sets that email as the Amplitude user ID, creates or reuses a persistent analytics device ID in local storage, and logs popup button-click events to api.amplitude.com with Amplitude's default tracking fields including IP address.
