AVOID - you will never stop paying!
Worst experience ever. I signed up and paid for a trial, and they led me to believe it is a one time payment. I ended my trial, did not opt in for extension, signed off the app and uninstalled it. Then - 3 years later I have found they kept charging me every 6 months - and more than that, never even send me an email to let me know I'm going to be charged/being charged. When I approached them, I got a laconic answer without any resolution.
