Why do you need to renew the license ?
Each our products' licenses are available for a variable time period, depending on the package the client purchased.
Standard Membership has its license available for 12 months, during which the user will receive updates and support. On the other hand, Developer Membership comes with a 2 years plan, and Lifetime Membership with lifetime updates and support.
After 1 year the license will be more expensive or cheaper ?
Usually, we do offer a discount for the renewal, so in most cases the renewal should be cheaper.
What happens when my license becomes invalid and i don't want to renew right away?
You can renew your license when you want and whenever you decide you will need support and updates, such as new features, security issues, bug fixes.
Note: The product will work for lifetime and you have full rights to use it as it is (GPL licensed), the only reason to renew is if you want updates and support when the license becomes invalid (You don't need to renew anythings on Lifetime Membership plan).
