This document lays out the general terms and conditions for use of this web platform, owned and held by Isigma Asesoría Tecnológica, S.L. (Hereinafter known as "ISIGMA") and the physical and/or legal persons (hereinafter known as the "TEST USER") stating their desire to access the services in Test User mode. Access to the service is limited to the volume of signatures and access time offered in each case by ISIGMA.

  1. b) Whereas access to PORTASIGMA is solely to test its use before possibly contracting the service.
  1. c) Whereas he or she is familiar with this access and use mode and accepts that it involves restrictions to the number of signatures contracts and its access time, in view of which he or she shall avoid any transactions or contracts with legal implications as these may be deleted in accordance with the conditions of ISIGMA.
  1. d) Whereas he or she shall not be deemed a CLIENT until any of the paid services offered by ISIGMA has been effectively contracted, which shall require the signing of certain General Terms and Conditions of Contract, along with other Specific Terms and Conditions, depending on the services contracted.

ISIGMA hereby indicates that, for legal reasons, it files the digital documents containing the acceptance of these General Terms and Conditions of Use, and the TEST USER may access them at any time.


ISIGMA reserves the right to modify these General Terms and Conditions at any time, without having to inform the TEST USER of such in advance. On all accounts, the TEST USER is responsible for reviewing them as a prerequisite to activating any service available via PORTASIGMA. The General Terms and Conditions indicated in PORTASIGMA when the TEST USER activates his or her account shall, however, be deemed valid and applicable.


4.1.

Likewise, the contact details of the TEST USER may be used by ISIGMA for commercial purposes, to promote or advertise similar products or services to those contracted, provided the TEST USER has given his or her express consent to do so. The TEST USER may exercise his or her right to objection in each communication, in accordance with the conditions set forth in this clause of the Contract.      

The TEST USER may exercise his or her rights of access, rectification, erasure, objection, restricted processing, portability and the right not be subject to automated individual decision-making, including the preparation of profiles, by writing to the postal or e-mail addresses indicated, providing a copy of his or her ID card or equivalent document, and identifying him or herself as a TEST USER of this service.

The following shall apply where the TEST USER provides personal data of third parties (e.g. signatories) for use of the tool:

The TEST USER declares to be legally protected in relation to the treatment of the data of the signatories of the documents uploaded to PORTASIGMA.

Under no circumstances may ISIGMA use the personal data provided by TEST USERS for purposes other than those indicated in these General Terms and Conditions of Use or those arising from the provision of the service. Nor may it transfer this data to third parties, not even for preservation purposes.

ISIGMA shall take all technical and organisational measures necessary to guarantee the protection of the personal data and files owned by the TEST USER from the destruction, loss, undue alteration, transfer and unauthorised access by it, and in all cases the security measures indicated in Article 32 of Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data (hereinafter known as the “GDPR”).

 For the purposes of data protection law, ISIGMA shall be considered the controller of the TEST USER data filed in PORTASIGMA and, according to this, it is expressly established that ISIGMA shall only process the data according to the instructions given by the TEST USER, as expressed in these General Terms and Conditions of Use, that it shall not apply or use said data for purposes other than those indicated herein and it shall not communicate said data, not even for preservation purposes, to other parties.

ISIGMA undertakes to adopt and implement the technical and organisational measures to guarantee the security, integrity and availability of the data housed in PORTASIGMA in accordance with current law, for the time that the TEST USER remains active.

ISIGMA is obliged not to subcontract any of the provisions forming part of the subject-matter of this Contract and that involve the processing of personal data, except for the auxiliary services necessary for the services of the Processor to function normally.

Where any processing must be subcontracted, the Controller must be informed 15 days in advance of such in writing, indicating the processing to be subcontracted, and clearly and unequivocally identifying the subcontracted company and its contract details. Subcontracting may occur if the Controller does not object within the term established.

The subcontractor shall also be considered the Processor and shall also be obliged to fulfil the obligations set forth in this document for ISIGMA and the instructions given by the Controller. The initial Processor is responsible for controlling the new relationship so that the Processor is subject to the same conditions (instructions, obligations, security measures, etc.) and with the same formal requirements as the former with regards to the appropriate processing of the personal data and to guaranteeing the rights of the data subjects. In the event of breach by the subcontractor, the Processor shall remain fully liable with regard to the Controller in terms of compliance with these obligations.

Notwithstanding the above, the CLIENT hereby expressly authorises the subcontracting of the services indicated below to the following providers:

ISIGMA hereby declares that, in relation to the above providers, it has signed a contract under the terms set forth in Art. 28 of the GDPR and that it shall respond directly to the CLIENT with regard to any breach that said providers may incur regarding personal data protection.

Once the test period is complete, and when no longer necessary to continue with the commission offered, the personal data shall be destroyed or returned by ISIGMA, along with any medium or document including any personal data subject to processing.


ISIGMA hereby indicates that PORTASIGMA, a digital signature solution, has been developed and designed by ISIGMA and holds the appropriate licences and permits to use any contents, programming code, design or materials associated to it.

The articles, contents, images or direct logos of the company are the property of ISIGMA or of individuals or companies that have expressly authorised their publication, or that are subject to licences that enable us to make an appropriate use of these materials along these lines.


These General Terms and Conditions are governed by Spanish law. The provisions of Article 29 of the Spanish Information Society and e-Commerce Law 34/2002 of 11 July shall apply in order to determine the location of sale to which these General Terms and Conditions are subject. Where the TEST USER is not considered a consumer, any dispute regarding the interpreting or implementation of these General Terms and Conditions of Use shall be subject to the jurisdiction of the Courts of the city of Barcelona.


Notwithstanding the above, the European Commission provides a platform to resolve on-line disputes, which is available at the following link: http://ec.europa.eu/consumers/odr/. TEST USERS considered consumers may subject their claims via the on-line dispute resolution platform.


Where any clause of these General Terms and Conditions is declared null and void, all other clauses shall remain valid and shall be interpreted in line with the will of the parties and the purpose of these terms and conditions.
