1. We're sharing our privacy policy on our chrome extension webstore page - did you manage to see it there? If not, we should definitely do a much better job presenting it, so thank you for pointing it out.
2. So sorry, definitely don't want to hide anything! We'll push out the changes asap to show our users how to remove your permissions. We stop looking at your data once you uninstall (even if you don't revoke permissions).
3.Sorry about that! You can remove it easily in the "EasyEmail" control panel - just hit "Settings" and you can uncheck the button
4. We'll keep getting better! Thanks for pointing out that we're suggesting some generic sentences - this tends to happen when the user didn't send a lot of emails from a given email address (which means there's not a lot of data to learn from.)
Again, thank you so much for your feedback. We'll get right to fixing all the problems!
