Licenses are valid for one year from the date of purchase. You will need a valid and active license key in order to get updates and support for purchased extensions and themes. After one year, you may renew license keys at a 50% discount from the then purchase price of a new license.
Updates are included for free for one year. If you have a valid and active license key, and your extension(s) supports it, updates will be delivered automatically from the WordPress dashboard. If your extension(s) does not support automatic upgrades, then updates can be downloaded from your account page in this site.
Support for purchased extensions is given up to one year after the purchase date. If you wish to get support after one year, you must purchase a new license for the extension you wish to get support for.
