Hi, we've decide not to develop this app any more to focus on other Avast apps.
If you have this app installed, you can install it on other devices via My apps tab in Google play or direct link.
Also server support will remain fully working, if you are using this app it will work as before.
If you want to download your data from My.avast.com, go to Device - Backup Section, select Calls/Contact/SMS and click on Download button.
