Date of Publish: 05/12/2022

Version: 3


This licence agreement (Licence or EULA) is a legal agreement between you (Licencee or you) and VIOLET ULTRA LTD. (trading as Rithum) of 128 City Road, London, EC1V 2NX (Licensor, us, we or Rithum) for:

  • ViOS (software embedded into Rithum products) (Software); and
  • online documentation (Documentation). 

We licence use of the Software and Documentation to you on the basis of this Licence. We do not sell the Software or Documentation to you. We remain the owners of the Software and Documentation at all times. 


    1. In consideration of you agreeing to abide by the terms of this Licence, the Licensor hereby grants to you a non-exclusive, non-transferable licence to use the Software and the Documentation in the UK on the terms of this Licence.
    2. You may:
      1. install and use the Software for your personal purposes, which such use shall only be possible only in connection with use of the smart home hardware technology provided by the Licensor; and
      2. receive and use any free supplementary software code or update of the Software incorporating “patches” and corrections of errors as may be provided by the Licensor from time to time (but see 1.3 and 1.4).
    3. We may update or require you to update the Software, including to updated versions of the Software (and, in certain instances, may require your consent before updating such Software, or may require your consent to update the licence agreement as relating to the use of the Software), provided that the Software shall always match the description of it that we provided to you before you bought it. In certain circumstances, to obtain the latest functionality, you may be required to incur further minor costs to obtain such functionality. However, you shall not be required to incur any costs in maintaining the level of functionality in the Software as in place as at the date of your taking out of this License.
    4. The Software may be upgraded from time to time. We will not be responsible if an upgrade affects how the Software works if this is caused by your own equipment – such as your smartphone or broadband – not supporting the upgrade.
    5. To use the Software, you will need to ensure that your smart home technology is compatible with the Software (as described within the Documentation).
  2. Restrictions
    Except as expressly set out in this Licence or as permitted by any local law, you undertake:
    1. not to copy the Software or Documentation, except where such copying is incidental to normal use of the Software or where it is necessary for the purpose of back-up or operational security;
    2. not to rent, lease, sub-licence, loan, translate, merge, adapt, vary, alter or modify, the whole or any part of the Software or Documentation nor permit the Software or any part of it to be combined with, or become incorporated in, any other programs;
    3. not to disassemble, de-compile, reverse engineer or create derivative works based on the whole or any part of the Software nor attempt to do any such things, except to the extent that (by virtue of sections 50B and 296A of the Copyright, Designs and Patents Act 1988) such actions cannot be prohibited because they are necessary to decompile the Software to obtain the information necessary to create an independent program that can be operated with the Software or with another program (Permitted Objective), and provided that the information obtained by you during such activities:
      1. is used only for the Permitted Objective;
      2. is not disclosed or communicated without the Licensor’s prior written consent to any third party to whom it is not necessary to disclose or communicate it in order to achieve the Permitted Objective; and
      3. is not used to create any software that is substantially similar in its expression to the Software;
    4. not to provide, or otherwise make available, the Software in any form, in whole or in part (including, but not limited to, program listings, object and source program listings, object code and source code) to any person without prior written consent from us;
    5. to comply with all applicable technology control or export laws and regulations.
  3. Intellectual property rights
    1. You acknowledge that all intellectual property rights in the Software and the Documentation throughout the world belong to us, that rights in the Software are licenced (not sold) to you, and that you have no intellectual property rights in, or to, the Software or the Documentation other than the right to use the Software and the Documentation in accordance with the terms of this Licence.
    2. Save as set out in condition 3.3 below, you acknowledge that you have no right to have access to the Software in source code form other than as expressly provided in this Licence.
    3. Certain items of independent, third-party code may be included in the Software (Open Source Software). The Open Source Software is licensed under the terms of the license that accompanies such Open Source Software. Nothing in this Licence limits your rights under, or grants you rights that supersede, the terms and conditions of any applicable end user license for such Open Source Software. In particular, nothing in this EULA restricts your right to copy, modify, and distribute such Open Source Software.
  4. Warranty and Indemnity
    1. If, within the Warranty Period (being 24 months from your purchase of this Licence in respect of the Software), you notify us in writing of any defect or fault in the Software as a result of which it fails to perform substantially in accordance with the Documentation, we will, at our sole option, either repair or replace the Software, provided that you give us proof of purchase and make available all the information that may be necessary to help us to remedy the defect or fault, including sufficient information to enable us to recreate the defect or fault. 
    2. The warranty does not apply:
      1. if the defect or fault in the Software results from you having altered or modified the Software; or
      2. if the defect or fault in the Software results from you having used the Software in breach of the terms of this Licence.
    3. This warranty is in addition to your legal rights in relation to Software that is faulty or not as described. Advice about your legal rights is available from your local Citizens’ Advice Bureau or Trading Standards office.
    4. The Software may give you the ability to access content, such as music or video services, television or other material, controlled or provided by third parties (“Third-Party Content”). Your right to use the Software is subject to the terms of any licenses relating to such technology and data, which are hereby incorporated in this Licence by this reference. You understand and acknowledge that: (a) Third-Party Content providers may restrict or revoke your access to their content at any time; (b) we are not responsible for and have no editorial control over any Third-Party Content, and we do not sponsor or endorse any such content; and (c) we have no control over the distribution of Third-Party Content. You agree that we will have no liability to you or to any third parties, including without limitation to anyone else who uses your Software, with regard to any Third-Party Content. You also agree and declare that any and all Third-Party Content accessed or transferred by you or your guests using the Software are for personal, non-commercial use and will not be used to illegally copy, display or otherwise make use of Third-Party Content without authorisation from the appropriate rights holder. Unauthorised copying or distribution of copyrighted or trademarked work or marks may constitute an infringement of the copyright or trademark holders’ intellectual property rights. We reserve the right to terminate your account if you infringe or may infringe (in our reasonable discretion) upon the intellectual property rights of others. In addition, steps intended to defeat or bypass security measures designed to prevent infringement of the intellectual property rights of others may be illegal under English law or comparable foreign laws. We reserve the right to terminate your account if you develop or use any method to defeat or bypass such security measures and to take any other necessary or appropriate action to prevent infringement of the intellectual property rights of others.
  5. Our responsibility for loss or damage suffered by you
    1. We are responsible to you for foreseeable loss and damage caused by us. If we fail to comply with these terms, we are responsible for loss or damage you suffer that is a foreseeable result of our breaking this Licence or our failing to use reasonable care and skill, but we are not responsible for any loss or damage that is not foreseeable. Loss or damage is foreseeable if either it is obvious that it will happen or if, at the time this Licence was made, both we and you knew it might happen. In all instances, the maximum extent of our legal liability to you under this agreement shall not exceed twice the amount that you have paid for the Rithum products.
    2. We do not exclude or limit in any way our liability to you where it would be unlawful to do so. This includes liability for death or personal injury caused by our negligence or the negligence of our employees, agents or subcontractors or for fraud or fraudulent misrepresentation.
    3. When we are liable for damage to your property. If defective digital content that we have supplied damages a device or digital content belonging to you, we will either repair the damage or pay you compensation. However, we will not be liable for damage that you could have avoided by following our advice to apply an update offered to you free of charge or for damage that was caused by you failing to correctly follow installation instructions or to have in place the minimum system requirements advised by us. In all instances, the maximum extent of our legal liability to you under this agreement shall not exceed twice the amount that you have paid for the Rithum products
    4. We are not liable for business losses. The Software is for domestic and private use. If you use the Software for any commercial, business or resale purpose we will have no liability to you for any loss of profit, loss of business, business interruption, or loss of business opportunity.
    5. You acknowledge that the Software has not been developed to meet your individual requirements, and that it is therefore your responsibility to ensure that the facilities and functions of the Software as described in the Documentation meet your requirements.
  6. Termination
    1. We may terminate this Licence immediately by written notice to you if you commit a material or persistent breach of this Licence which you fail to remedy (if remediable) within 14 days after the service of written notice requiring you to do so. 
    2. Upon termination for any reason:
      1. all rights granted to you under this Licence shall cease;
      2. you must cease all activities authorised by this Licence; and
      3. you must immediately delete or remove the Software from all computer equipment in your possession (except that which is embedded into Rithum products) and immediately destroy or return to us (at our option) all copies of the Software then in your possession, custody or control and, in the case of destruction, certify to us that you have done so.
  7. Communications between us
    1. If you are a consumer, if you wish to contact us in writing, or if any condition in this Licence requires you to give us notice in writing, you can send this to us by email or by pre-paid post to Violet Ultra Ltd. at info@rithumhome.com. We will confirm receipt of this by contacting you in writing, normally by email.
    2. If we have to contact you or give you notice in writing, we will do so by email or by pre-paid post to the address you provide or confirm to us.
  8. How we may use your personal information
    1. Under data protection legislation, we are required to provide you with certain information about who we are, how we process your personal data and for what purposes and your rights in relation to your personal data and how to exercise them. This information is provided in https://rithumhome.com/privacy-policy/ and it is important that you read that information which you agree to by accepting the terms of this EULA, one important element being how we handle Rithdum Device Diagnostics.
  9. Other important terms
    1. We may transfer our rights and obligations under these terms to another organisation. We will always tell you in writing if this happens and we will ensure that the transfer will not affect your rights under the contract. 
    2. You may only transfer your rights or your obligations under this Licence to another person if we agree in writing
    3. This agreement does not give rise to any rights under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of this agreement.
    4. Each of the conditions of these terms operates separately. If any court or relevant authority decides that any of them are unlawful, the remaining conditions will remain in full force and effect.
    5. If we do not insist immediately that you do anything you are required to do under these terms, or if we delay in taking steps against you in respect of your breaking this contract, that will not mean that you do not have to do those things and it will not prevent us taking steps against you at a later date.
    6. Which laws apply to this contract and where you may bring legal proceedings. These terms are governed by English law and you can bring legal proceedings in respect of the products in the English courts. If you live in Scotland you can bring legal proceedings in respect of the products in either the Scottish or the English courts. If you live in Northern Ireland you can bring legal proceedings in respect of the products in either the Northern Irish or the English courts.
