All our WordPress themes are licensed under the GNU general public license. So, you may use them on as many websites as you like and you can distribute them as well. Please check the readme.txt file in your theme folder after you download the theme.
It is our duty to always keep the themes up-to-date and working with the latest version of WordPress. The minimal requirement for our themes is the same as WordPress, which is version 5.2.4 or greater (recommended: PHP 5.4 or greater) and MySQL version 5.0 or greater (recommended: MySQL 5.5 or greater). http://wordpress.org/about/requirements/. We can ensure but not guaranteed, that themes/plugin will work with all third-party components, plugins or web browsers.
Our themes have been tested to work on Firefox, Google Chrome, safari and Internet Explorer 10.
Our themes are guaranteed to run on the latest stable version of WordPress. Generally, we are not giving any warranty for the correct functionality of our themes – especially if you use third-party software (e.g. any WP Plugins) or modify the theme files. Also we reserve the right to reject support requests for problems that occur after theme files have been modified or third party plugins have been installed.
