Thanks for this great plugin! Can Google read the contents of the email once it's unencrypted and is being shown in my browser?
Hello, FlowCrypt uses end-to-end encryption that is designed so that only you and your intended recipients can read it.
When using FlowCrypt in the browser, decrypted messages are being displayed in a separate frame that Google doesn't have access to even if they deliberately tried to. They would first have to somehow update your browser to one that includes a deliberate vulnerability, but that's more of a stretch.
I personally use SRWare Iron (chrome based) for my primary browser.
