I like your plugin WP User Frontend and I plan to purchase it. when I read your documentation I was confused because you said in your documentation in the FAQ section :
Q. What happens after 1 year period?
Ans: You are buying the plugin with 1 year free support and updates. After 1 year, depending on your purchased package, to get update and support again, you’ve to renew your license each year. The renewal fee for personal package is $29, business: $49 and developer license is $79.
And on the your pricing options and for the developer option you said :
1 Year Priority support & lifetime update
So I can't understand. could you explain that to me is update lifetime or what ?
