Personally I do not use their service as seen some warning reviews from customer/users in their app's review section means I have to choose alternative one,most of the cases these online based wallet is not the final solution,better to have hardware wallet,hope you will back your coins
Additionally, you connect to there server. I remember when the BCH fork was about to happen and they shut down the Bitcoin wallet access as a safety precaution, which I understand, but I don't like the fact that they locked me out of my own funds. It wasn't much since I store my crypto elsewhere, but it was an eye opening experience as a Jaxx user.
