I purchased a one year license (4 devices) for $9.99 some time ago. I liked this software very much, however…
They never asked if I wanted to renew my license after a year and I could not find in my profile a section on automatic renewal. Instead my credit card was billed $49.99 to renew the license. It took a lot to get a refund. I almost had to do a charge back on my credit card.
So in sum, this is good software and does the job, but if you decide to install and use it, be careful. If you don’t have to provide a credit card number though, you should be good. Just give it a try for 3 months and be prepared for the nagging to purchase a license at an inflated price.
