License for payment modules

If you want to sell or purchase Payment Add-ons, this is your license. Read the following clauses carefully, because they establish a series of rights, but also obligations to which you agree. Everything that is not included here
It is regulated by the Terms and Conditions of the Platform, so do not stop consulting them anyway.

Some definitions.

  • Application: element resulting from the compilation process, which is offered on distribution platforms for use on mobile devices.
  • Author: registered user under whose profile a Complement is offered for sale, and who owns all intellectual or industrial property rights over it, so that it publishes, licenses and allows be used legally in an Application.
  • Add-on: modules, templates, themes and other plug-ins that are purchased from King of App and are subject to this license.
  • Platform, Web: is used to refer to the website as a whole in which King of App provides its services and offers its products.

What this license implies.

The Author is the owner or has permission.

The Author must be the owner of the intellectual, industrial, image or other property rights that may fall on the Plugin or its content, or be authorized to allow users to legally use the Plugins, within the limits of this license.

Why it is important.

If the Author did not have those rights or permissions, the publication in King of App or the use of the Plugin by users would not be legal: we would be using something that does not belong to us, in a way that is not allowed. In the event that the Author is committing, with or in his Supplement, any violation of copyright or third party rights, he will be fully responsible to the legitimate owners, to the users and to King of App for the damages and damages of any kind derived from the infringement, keeping them harmless from third party claims.

The license authorizes, does not sell.

By granting this license, the Author is not selling the Plug-in, but rather giving a series of permissions to the user. These permissions define what can and cannot be done, since everything that is not expressly allowed will be reserved for the Author.

Use of licenses with copyleft .

The licenses that some of the contents of the Plugins may have must, in any case, be compatible with these terms and conditions. There is content and software whose use is only allowed on the condition that the terms of their licenses (called strict copyleft licenses) also apply to all those works in which they are integrated. In King of App we want each Author to be able to choose how to license his Plugins, and that each user can in turn license his Applications respecting the conditions of the distribution platforms. Therefore, the Author undertakes to not include in the Plugins creations whose licenses oblige other programs, pieces of code or intellectual creations with which they integrate, communicate or link, to be licensed under the same conditions.

King of App as an intermediary.

King of App only intermediate. It does not edit, review or have knowledge of all the published content. King of App offers a technology as a tool to publish, design and edit Plugins, and a meeting point for designers (Authors) and users. The Terms and Conditions define the framework of guarantees and responsibility of King of App, the Authors and the users. The Author is the one who licenses the Complement from him, and therefore this license is between him and the users. King of App enables this relationship, providing technology and a meeting point, a marketplace . This publication and license is made by the Author from his registered user profile, selecting in the process what type of license he wants. The user, when acquiring a Plugin, agrees to use it under these terms.

Terms and Conditions of the Web.

The terms of use of the Platform complement the provisions of this license, and will be applied in a subsidiary manner for those cases in which it does not contain a specific regulation. But, if there is a conflict between the terms of both, those of the license are of preferential application.

For whom and for what.

What is the scope of this license.

Add-ons under this paid license are offered to registered users. This license makes it possible for users to access the source code and personalization of the Plugin, with the aim of integrating those Plugins into an Application mobile number, compiled under King of App ID or under the user’s ID, Product that will later be distributed on the different third-party platforms for mobile applications. The Author, and not King of App, is the licensor of the Plug-in, and therefore authorizes its use under the terms of this license.

License for compilation, publication and sale on distribution platforms.

The services offered by King of App include the compilation, publication and sale of the Mobile Applications on the distribution platforms of operators such as Apple or Google.

  4. When the Application is the result of an order by a client of the licensee user, it will be understood that the user has acquired the Complement on behalf of that client only, having to acquire another license for other clients who may need it.

What commitments does the user have.

This license may be terminated if the user breaches any of its terms.
