Plugin Licensing

All products are licensed under the GNU general public license (http://www.gnu.org/licenses/gpl.html).

Automatic Updates

Automatic updates are available to customers who have purchased a license, but are limited to the number of installs specified on the corresponding pricing page. Installs can be deactivated at anytime from My Account to free up install usage.

Updates are provided for a term of 1 year from the time of purchase. After 1 year either a license renewal or a new license will need to be purchased in order to continue receiving support and product upgrades.

You may not resell access to your account or your license key. All licenses are reserved for individual use and may not be shared by several individuals.


After payment has been successfully processed, you will be directed to a copy of your receipt that contains download link(s) and license key(s). This receipt will also be emailed to you. This may take up to 1 hour to arrive, but usually happens instantly when placing the order. If you do not receive an email after this time period, please contact us. You may also login to My Account with the email address you used to purchase the plugin for instant access to all support related material.

Xtendify Technologies offers WordPress plugins “as is” and with no implied meaning that they will function exactly as you would like or will be compatible with all 3rd party components and plugins. We do not provide support services for WordPress itself or other WordPress plugins we have not developed.

Support is offered via a license key. Purchasing a license key gives you access to our support services.

Support and automatic product updates are provided for a term of 1 year from the time of purchase. After 1 year, renewing your license or purchasing a new license will need to be purchased in order to continue receiving support, product updates, and premium functionality.

Support and updates for plugins sold are provided as long as the plugin is actively in development. Should any one of the following occur, Xtendify Technologies will no longer be responsible for providing support for the plugin:

– The plugin is no longer actively developed as a viable product under Xtendify Technologies.

– The plugin or the parent company is purchased or bought out by another company.

– WordPress is no longer actively developed.

While we attempt to provide the best support possible for our plugins, we do not guarantee that any particular support query can, or will be answered to the extent, or within a timeframe that the inquirer is completely satisfied.

License holders cannot distribute, freely giveaway, or resell their license key. The license key is only transferable by contacting us and requesting an official transfer of the license to a new owner. The license is intended to be used on the license holders web site(s). Client site usage is permitted in situations where the license holder maintains an ongoing relationship with the client as a consultant. Only the license holder is permitted to request support or access support resources.

License holders are not permitted to re-post support content or documentation on any external websites, social media outlets, etc. Posting screen captures of this content is also prohibited. Violation will be grounds for immediate termination of the support license and all access to support content and product updates will be discontinued.
