Summary: Do not recommend. This software badgers the user.
Details: I'm in the process of being more studious about my privacy. That said, I see no reason why a translation add-on needs any information from me whatsoever beyond the text I input or highlight to be translated and maybe some non-identifying use data to keep up on how the add-on behaves. I shouldn't need a profile or account. While I'm not obligated to have one to use the add-on, because I'm not signing up for one, the add-on has interrupted my browser use with a full-screen pop-up window to sign up with an account once per hour in the two hours I've had the add-on, and there was an exact one hour gap between the pop-ups. That tells me all I need to know about this add-on and what I can expect from it going forward, and I'm uninstalling it. Do better.
