1. The link to the privacy policy comes AFTER you take all my data. 2. If I uninstall your extension you have it programmed to give me an exit survey, but it doesn't prompt me to revoke access for your app from my account? So you can continue to read all my communications. At the very least tell me how to remove it when I uninstall your extension, or fill out your exit survey. Don't just hide the fact that you retain access indefinitely. 3. You are appending your marketing to the bottom of every email regardless if it used your product or not. Thats crap, I don't want to spam every single person I communicate with. Let me opt in, or only append when your plugin is used.
I get its a prototype, I get the "potential", but it seems you put 0 critical thought into making the app safe.
