These Conditions shall remain published and available to the client so that they may be reproduced and saved as confirmation of the provision and download, and may be modified at any time by the PROVIDER. It is the client’s responsibility to read them periodically, since those in force at the time downloads are made shall be applicable.

Has read, understands and comprehends what is set out herein.

In some cases the user will not be the same person who manages the contracting and download of the service, and will therefore act on that person’s behalf (for example: companies, users, etc.).
Subject matter of the contract
The purpose of this contract is to govern the contractual download relationship arising between the PROVIDER and the client at the moment the latter accepts the corresponding box during the online contracting process. The contractual relationship entails the download of the app, in exchange for a specified price publicly displayed through the application, for the use thereof.
Intellectual property
The USER is not permitted in any way to transfer, change or exchange the licence rights and obligations affecting
this contract, save that the form and content may be altered on
condition that the changes are pre-agreed and made in writing by the PROVIDER. However, this contract -or general download conditions- expressly excludes any transfer of ownership from the PROVIDER to the USER.
Contracting procedure
In order to access the services offered by the PROVIDER, the client and the user must be over 16 years of age and must register through the app by creating a user account.

ACTIVATION OF SERVICES
The PROVIDER will not activate any service until it has verified that payment has been made.
Since the enjoyment or use of the service does not involve the physical delivery of any product, the contracted services being downloaded or activated directly, the PROVIDER will inform the client in advance of the procedure to be followed in order to carry out this download or activation.

Given the continuous technical advances and improvements to the services, the PROVIDER reserves the right to modify their specifications with respect to the information provided in its advertising, insofar as this does not affect the value of the services offered.

The PROVIDER, without prejudice to any of its rights and responsibilities, shall inform the client, within a reasonable period of time, of the date on which it proposes to carry out the maintenance.
The USER acknowledges that the download or use may be unavailable where the USER cannot or is unable to access the Internet. The PROVIDER shall not be liable for the client’s inability to gain access under these circumstances.

In order to achieve these purposes, the user/client accepts that the provider obtains data for the purpose of the corresponding authentication of the access controls.
