Terms of Service

Last updated: September 17 2026

 

  1. Introduction 

These Terms of Use (“Terms”) and our Privacy Policy incorporated herein by reference, constitute a legally binding agreement between you (“user“ or ”you“) and Kavento Studio Ltd. (“we“, ”us“, “Kavento Studio” or ”our“) and govern your use of this website (“website”) and your use of our Chat Lightning browser extension (“Extension” or “Product”).  

Please read these Terms carefully before downloading or using our Product and any feature provided therein. By clicking the “Download” (or similar button), installing the Extension or using the website or the Product you acknowledge that you have read, understood, and agree to be bound by these Terms. 

 

  1. Amendments 

We may amend these Terms from time to time, at our sole discretion and without any notice. We will make a reasonable effort, at our sole discretion, to provide you with a notification regarding what we believe are material changes to these Terms. Such material changes will take effect seven (7) days after such notice was provided. Otherwise, all other changes to these Terms are effective as of the stated “Last Updated” date and your continued use of the Services following the Last Updated date will constitute acceptance of, and agreement to be bound by, those changes. 

 

  1. Eligibility and Age Limitation 

You hereby warrant that you are eligible to enter into these Terms and you are not prohibited by any authorized authority, judicial order or law into entering in any agreement; you have all proper authorization, if you are acting on behalf of a corporation, to enter into these Terms. You further represent and warrant that you are of legal competence to enter into these Terms and you are at least eighteen (18) years of age. We reserve the right to request proof of age at any stage so that we can verify that children (as defined under applicable law) are not using the Services. If you are under 18, please be sure to read these Terms with your parents or legal guardians and ask questions about things you do not understand. 

 

  1. Scope of Services 

The Product is designed to improve chat response times and reduce token usage when you use supported AI models, such as ChatGPT, Gemini, and others. To provide these features the Product trims the rendered message list so that long conversations load and scroll more quickly, and uses browser storage to retain conversation information rather than continuously keeping the full chat history loaded. This may optimize memory usage and enable users to scroll through longer chat histories more quickly. The Product also provides prompt and input tools, including prompt rewriting, document upload, URL content fetching, prompt history, and a character counter, as well as message and appearance tools, including per-message copying, character and word counts, visual hiding of messages, message-width controls, presentation blur. The Extension does not operate a backend or transmit your data, except where you voluntarily initiate a URL content fetch, in which case the relevant URL is transmitted to retrieve its content (collectively, the “Services”). Subject to your acceptance of these Terms, you may choose to use our Services by installing the Product. 

The use of the Services is free of charge. We reserve the right, at any time and from time to time, at our own discretion, to add Services, to modify, suspend, terminate or discontinue any or all the Services, or any part thereof or any user’s access thereto. Where we assume that such change may affect an existing Service, we will provide you with prior written notice and you may be able to terminate the Service in accordance with section 12 below.  

 

  1. AI provisions 

You may submit text, prompts, images, and other content through the Product and related services (“Input“). The Services may allow you to access or use AI models, tools, or services provided by independent third parties, which may generate text, images, edits, or other results (“Output“). Input and Output together are “User Content.” The Company is not a provider or operator of any such AI models and only facilitates access to third-party AI tools. Your use of those tools and any Output may be subject to the applicable third-party terms, policies, and rules, and you are responsible for complying with them. You are solely responsible for your User Content and for ensuring that your Input and use of the Services comply with applicable law and do not violate any third-party rights. The Company is not obligated to review or monitor User Content.  

 

Output is provided “as is.” To the maximum extent permitted by law, the Company makes no representations or warranties regarding any Output, including its accuracy, completeness, reliability, lawfulness, non-infringement, or fitness for a particular purpose. You acknowledge that Output is generated by third-party AI tools, not by the Company, and that the Company has no liability for any Output or any issue arising from or related to such AI tools. Any use of or reliance on Output is at your sole risk. 

 

Due to the nature of AI, Output may not be unique and may be incomplete, inaccurate, misleading, offensive, or otherwise objectionable. References in Output to third-party products or services do not imply any endorsement, sponsorship, or affiliation by the Company. 

 

You are solely responsible for reviewing all Output before using or relying on it, and the Company disclaims liability for any unintended Output or consequences arising from its use.   

 

  1. Intellectual Property 

Subject to your compliance with the Terms, we hereby grant you a personal, limited, revocable, non-transferable, non-sub-licensable and non-exclusive right to use, access, download and install the most current generally available version of our Product (including all updates thereto) and use the Services solely in connection with your lawful, personal and non-commercial use.
