Welcome to the OLYMPUS web application (the “Platform”, or “we” or “us” collectively). Below, we will detail the license agreement that governs the terms on which you, as a User, may use the Platform and the Services offered therein.

This document (together with all documents referred to herein) sets forth the terms and conditions governing the use of this Platform (https://app.darkearth.gg) and the use of the Service provided through this Platform (the “Terms and Conditions”).

Please read these Terms and Conditions and our Privacy and Cookie Policy carefully before using the Platform.

By using the service provided on this Platform the User agrees to be bound by the Terms and Conditions, as well as by our Privacy and Cookie Policy, therefore, if the User does not agree with all the stipulations of the Terms and Conditions and with the Privacy and Cookie Policy, he/she should not use this Platform.

In compliance with the duty of information contained in Article 10 of Law 34/2002, of July 11, of Services of the Information Society and Electronic Commerce, the following data of the owner are reflected below:

  • TAX ID: B67814160
  • Registered office: Calle de la isla de La Graciosa 1, planta 2 puerta 5, 28073 San Sebastián de los Reyes, Madrid, Spain.
  1. USERS and consent

The use of the Platform attributes the condition of User, who accepts, from the access, download and / or use of the same, the Terms and Conditions reflected here.

To make use of the Services offered on the Platform, the User must be over 18 years of age.

Likewise, the User declares that the use of this Platform is done on a personal basis, without performing any type of professional service.

The Platform will allow the User to access the Services specified in these Terms and Conditions.

Before making use of the Services, the User should be aware that the risk of loss in buying and selling or holding Cryptoassets or NFTs may be substantial. As with any asset, the value of Cryptoassets and NFTs can vary considerably and there is a substantial risk that you may lose money buying, selling, holding or investing in NFTs and Cryptoassets. Therefore, by using the Platform, the User acknowledges and accepts the risks involved in buying, selling, or holding NFTs and/or Cryptoassets.

Furthermore, by using the Platform the User agrees that OLYMPUS does not provide any investment advice in relation to Cryptoassets or the NFTs that can be acquired through the Platform.

Cryptoasset services are not currently regulated by the financial authorities nor do they fall under the umbrella of protection that may be offered by financial services clearing schemes in Spain, therefore, the User should carefully consider whether trading or holding Cryptoassets and NFTs is appropriate.

  1. RISKS

Furthermore, by accepting these terms and conditions, the User acknowledges and agrees that:

  • The prices of NFTs and Ctyptoassets are extremely volatile.
  • The User is solely responsible for determining what taxes apply to its transactions of NFTs and Cryptoassets and for fulfilling its tax obligations.
  • The Service does not involve in any case the storage of NFTs and/or Cryptoassets. Any transfer of the same occurs within the selected Blockchain and not on the Platform.
  • Cryptoassets and NFTs are more volatile relative to most fiat currencies and other assets, and this unpredictability of their price can result in significant losses in a short period of time. OLYMPUS is not responsible for the market for NFTs and Cryptoassets, and makes no representations or warranties regarding the actual or perceived value of any digital asset, and the quality, suitability, truthfulness, usefulness, accuracy or completeness of any information provided by OLYMPUS. Therefore, it is for you to carefully consider whether holding NFTs and Cryptoassets is suitable for you in light of your financial condition.
  • Cryptoassets are not money or legal tender in many countries, are not backed by the government or a central bank and most do not have any underlying assets, income streams or the like.
  • The value of Cryptoassets and NFTs may derive from the continued willingness of market participants to exchange fiat currencies for cryptoassets which may result in the permanent and total loss of the value of cryptoassets, particularly in the event that the market for the same disappears.
  • The User is responsible for determining whether use of the service is legal in his or her jurisdiction and should refrain from use if it is illegal in his or her jurisdiction. If you are unsure, seek independent legal advice.
  • We may be forced to suspend, terminate or change features and services in any jurisdiction without notice if required to do so by regulatory authorities or applicable law, or for any other reason. In such an event, access to the Platform will be prevented for an indefinite period of time and legal grounds until the matter is resolved.
  • The User understands and agrees that he/she uses the service at his/her own risk. This clause is not exhaustive and does not disclose all risks associated with NFTs, Cryptoassets and the use of OLYMPUS or related Services. Therefore, the User should carefully assess the appropriateness of their use based on their specific circumstances and financial resources.

OLYMPUS offers through the Platform the Services specified in these Terms and Conditions, which allow the User to acquire NFTs with certain utilities.

The User assumes responsibility for the use of the Platform. This responsibility extends to the registration, if any, was necessary to access the Services. In such registration, if requested, the User shall be responsible for providing truthful and lawful information.

OLYMPUS reserves the right to request that information be updated if it becomes aware of any changes.

Likewise, OLYMPUS reserves the right to carry out the appropriate checks in order to confirm the legal origin of the contributions of funds that are made.

The User agrees to make appropriate use of the content and services that OLYMPUS offers through the Platform and, by way of example, but not limited to, not to use them for the following purposes

  • engage in activities that are illicit, illegal or contrary to good faith and public order;
  • disseminate content or propaganda of a racist, xenophobic, pornographic-illegal nature, in support of terrorism or against human rights;
  • cause damage to the physical and logical systems of OLYMPUS, its suppliers or third parties, introduce or disseminate computer viruses or any other physical or logical systems that are likely to cause the aforementioned damage;
  • use any OLYMPUS Intellectual Property material for your own benefit (except for the rights you acquire by purchasing NFTs, specified in section 7 of these Terms and Conditions).

OLYMPUS reserves the right to interrupt access to the Services at any time and without prior notice, whether for technical, security, control, maintenance, power failure or any other justified cause.

Consequently, OLYMPUS does not guarantee the reliability, availability or permanent continuity of the Platform or the Services, so that the use of the same by the Users is carried out at their own risk, without, at any time, OLYMPUS can be held liable in this regard.

In addition, OLYMPUS assumes no liability whatsoever arising from, but not limited to:

  • The use that Users make of the materials available on the Platform, whether prohibited or permitted, in violation of intellectual property rights and / or industrial content of the website itself or third party portals.
  • For possible damages to Users caused by a normal or abnormal operation of the search tools, the organization or location of the contents and/or access to the Services and, in general, of the errors or problems generated in the development or instrumentation of the technical elements that form the Service.
  • Of the contents of those pages to which the Users can access from links included in the Platform.
  • The acts or omissions of third parties, irrespective of whether such third parties may be contractually bound to OLYMPUS.

Similarly, OLYMPUS excludes any liability for damages of any kind that may be due to the presence of viruses or the presence of other harmful elements in the contents that may cause alterations in computer systems, as well as in the documents or systems stored therein, so that OLYMPUS will not be liable in any case when they occur:

  • Errors or delays in the access to the Services by the User when entering his data in the corresponding form or any anomaly that may arise when these incidents are due to problems in the Internet network, causes of fortuitous event or force majeure and any other unforeseeable contingency beyond the good faith of OLYMPUS.
  • Failures or incidents that may occur in communications, deletion or incomplete transmissions, so that the Platform Services are not guaranteed to be constantly operational.
  • Errors or damages caused to the website due to inefficient and bad faith use of the Service by the User.
  • Non-operability or problems with the email address provided by the User to send the requested information, or with the cell phone networks or OLYMPUS providers, regarding the reception of SMS messages.

In any case, OLYMPUS undertakes to solve the problems that may arise and to offer all the necessary support to the User to reach a quick and satisfactory solution to the incident.

Disclaimer of warranties and liability with respect to Blockchain. Forks and modifications to Blockchain protocols.

OLYMPUS does not own or control the underlying software protocols governing the operation of the Blockchain linked to the NFTs and Cryptoassets supported by the Platform. For the most part such protocols are open source or open source and any third party may use, copy, modify and distribute them. Consequently, OLYMPUS assumes no responsibility for the operation of such protocols and does not guarantee their functionality, security or availability. The User acknowledges and accepts the risk that the underlying software protocols related to any Cryptoassets it acquires may change. In particular, Users should consider forks with the impact they may eventually have on the value of the Cryptoassets.

In the event of a Fork, the User agrees that OLYMPUS may temporarily suspend its operations (with or without notice) and, if it deems it necessary, (a) configure or reconfigure its systems or (b) decide not to support (or to stop supporting) a protocol and/or the original and/or the alternative Cryptoasset.

Likewise, OLYMPUS will notify Users of any modifications to the protocols of the Blockchains associated with the Cryptoassets and whose implementation is not possible to perform on the Platform.

The User acknowledges and agrees that OLYMPUS assumes no responsibility for any consequences in the provision of the Service that may arise in connection with the modification of the Blockchain protocols or for the interruption in the operation of such protocols.


The User who wishes to purchase NFTs from the game, must connect his Wallet assuming the corresponding T&C of the service of these third parties, for which OLYMPUS assumes no responsibility.

The Service is subject to the User reading and accepting the Platform Terms and Conditions.

The purchase of NFTs and Cryptoassets are recorded in Blockchain, a technology that operates like ledgers, intended to immutably record transactions in networks of computer systems.

Many of these public Blockchains allow forensic analysis that can lead to de-anonymization and inadvertent disclosure of private financial information, especially when blockchain data is combined with other data.

Since blockchains are decentralized or third-party networks that are not controlled or operated by OLYMPUS, we cannot delete, modify or alter personal data on such networks. For more information you can refer to our privacy policy.
