Starting on January 1, 2018, your PERRLA purchase includes a one-year subscription to all of PERRLA's products!
This means you get 12 months of update and support for PERRLA Online and PERRLA for Word (Mac & PC). After your 12 months is up, you can renew for another year.
If your subscription expires, then your PERRLA products will no longer work.
