Terms of Use

1.1. These Terms of Use (hereinafter “Terms”) establish the rules and conditions governing access, registration and use of the Sophea Nous digital platform, which constitutes an artificial intelligence product developed and managed by the company KIEFER Societe Anonyme (headquarters at 44 Kifisias Avenue, P.O. 15125 Marousi Attiki, Greece) (hereinafter “the Company” or “we”).

1.2. Sophea Nous is an advanced digital assistant that provides automated responses and information in various knowledge domains, using proprietary machine learning and natural language architecture, specifically trained for the Greek and English languages (the “Platform”).

1.3. The Platform is addressed to all visitors (natural persons) of the website, web application, or mobile application versions of the Platform that access and engage with it after creating a personal account and submitting the required identification and communication detail (“User”, “you”). By creating an account and/or starting to use the Platform, the user declares that they have read, understood, and unconditionally accept these Terms, as well as the Privacy Policy, Cookie Policy, and AI Disclaimer and any other policy or notice published or made available through the platform, which altogether constitute the legally-binding contract between the User and the Company for the use of the Platform (reference to Terms herein will be considered to include any of the legal texts mentioned above, unless otherwise provided for or is derived from context). In case of non-acceptance of the Terms, the visitor and/or User must refrain from any use of the Platform; use of the Platform implies non-negotiable acceptance of the Terms.

1.4. In case your access to the Platform has been granted as part of a business account, the specific terms agreed govern the use of the Platform and the Services. Please consult with your system administrator regarding the terms and conditions applicable to your use of the Platform in the context of your business account.

2.1. Minimum age: The Platform is intended for use by natural persons over 16 years of age. If you are below the above minimum age threshold, do not use the Platform and the Services, do not register with an Account and do not provide any data.

2.2. Account Registration: To access the Platform, you need to create an account as a User (“User Account” or “Account”). You can sign up for an Account by entering your details (name, surname, email, phone number and a password) in the relevant sign-up area in the Platform. You will be required to confirm your e-mail address when prompted through the verification e-mail sent to the address provided. When you insert your details in the dedicated fields, you warrant that the data you provide are accurate, correct, true, complete, and up-to-date and that you are lawfully disclosing them to us and that you shall update such data upon the occurrence of any change.

2.3. Password security: You are solely responsible for keeping your password secure and must not share it with any third parties. If you suspect disclosure or unauthorized use, you must notify the Company immediately. You are responsible for all activity taking place through or on your Account until such notice. The Company is not liable for losses from unauthorized use prior to notification. If you lose or forget your password, you may use the ‘Forgot My Password’ function to reset it. Each account is intended for use by a single, specifically identified individual, and access credentials may not be shared; each account corresponds to one named user only.

2.4. Access to Services & Features: The services offered through the Platform include (a) a general-purpose conversational assistant that processes natural-language prompts to generate various forms of image, video and text through chatting, (b) AI-agents specialized on specific domains, tailored to provide answers curated in that specific context (legal, environmental, travel etc) (“Services”). The Services are provided with various sets of features, usage limits and support levels (“Features”).

2.5. Account Termination: We may take action to restrict, suspend, or terminate your access to our Services or close your account if we determine, acting reasonably and objectively:

• 2.5.1. You breached these Terms.
• 2.5.2. We must do so to comply with the law.
• 2.5.3. Your use of our Services could cause risk or harm to our Company, our Users, or anyone else.

In case of Account Termination as per above, we will keep your User Content for a period of 12 months. If we terminate your account, we will make reasonable efforts to notify you in advance so you can export your Content or your data from the Services, unless it is not appropriate for us to do so, we reasonably believe that continued access to your account will cause damage to the Company, the Platform or anyone else, or we are legally prohibited from doing so.

3.1. Tiers: Access to the Platform is available through (free and paid) subscription plans (“Tiers”), each featuring various Services and/or Features. Depending on the Tier to which they are subscribed, the Users may access different Services and Features, by paying the respective fees (“Fees” or “Pricing”) as described on the Pricing page. Certain Services and/or Features are available only on specific Tiers. User access is limited to the Services and / or Features included in the Tier subscribed to. The applicable tiers and corresponding Features, as updated or modified from time to time, are available at: Pricing page.

3.2. Upgrade or Downgrade Tiers: Users may upgrade or downgrade Tiers at any time, by managing their subscription through the User Settings. Upgrades take effect immediately: Upon upgrading, additional Services and/or Features become available immediately. If a User upgrades to a higher Tier during an already active and paid billing term, the fees are prorated for the remainder of the then-current billing period. This means that the User will be immediately charged only for the price difference between the new Tier and their old Tier, for the remaining days of the current period. After the current Term lapses, the new Tier subscription fees will apply. Downgrades take effect at the end of the then-current billing period unless otherwise agreed. You will continue to have access to the Services and Features of your Tier until the end of the subscription period you have paid for, at which point your downgrade becomes effective. You will not receive a refund or service credit for any days between the day you downgrade and the last day of the subscription period you have paid for, unless otherwise specified.

3.3. Cancellation: You may cancel your subscription at any time; however, the full subscription fee for the then-current billing period remains payable in all cases. Cancellation does not entitle you to any refund, rebate, or credit for any unused portion of the billing period, and the Services and Features will remain available to you until the end of the period you have already paid for.

3.4. Valid Payment Method: To activate any of the Tiers other than the free version of the Platform, you are required to present us with a valid payment method (credit, debit, or prepaid card), when prompted. You warrant and represent that the payment card details you provide are valid and correct, and that you are properly and fully authorized to use this card for the purposes described herein and accordingly be bound by the actions performed through it. In particular, you expressly authorize us to charge your card automatically through recurring direct debit issued for your card. This recurring authorization is perpetual and subject to your revocation (for the future) by notification in writing. You cannot change your payment card unless you simultaneously replace it with another; you must always have a payment card available on the Platform. The payment card must always have available funds equal to the Fees of the Tier you have registered for. If your card does not have enough funds to cover the Fees on the payment due date of each subscription term, we may suspend your Tier access until the Fees are paid out. If your payment does not go through on the payment due date, you will be notified to change your payment card or increase your bank account balance. We will attempt charging your card two (2) more times within the first week after the payment due date, after notifying you of the discrepancy. Once we have proceeded to three (3) failed attempts to charge your card your Tier access will be suspended until the Fees are paid out. This will result in your access being limited to the free Tier version of the Platform. Until you update your payment card and/or account balance, your Account access will not be reinstated.

3.5. Transactions are executed exclusively and automatically through the payment service provider with which we cooperate, which provides all necessary security guarantees for the completion of electronic payments. We do not keep or process any of your payment data; your data is collected directly by the payment service provider.

4.1. The Platform processes the text, documents, images, and photos that Users upload as well as the prompts used by the Users (“User Content”) to generate automated responses (“Outputs”). Outputs may also be generated using the Platform’s own databases, knowledge sources, system materials, and internal model information, as well as through the synthesis of a User’s interaction history or previously provided information. User Content includes all types of texts, images, documents, links, images, icons, photos uploaded directly to the Platform, as well as material synchronized (synced) through connection with the User’s internal servers (e.g. when the Users syncs their material hosted in a cloud server such as Sharepoint, One Drive, Zapier etc). Output may in turn be combined with User Content to generate further Output and so on. The Platform may generate also synthetic (artificial) content that does not reflect actual events, persons or data. User Content and Outputs used in or by the Platform by the User to generate further Outputs, as well as all Outputs, shall altogether be referred to as “Content”.

4.2. You represent and warrant that you have all rights, licenses, and permissions needed to provide User Content to our Platform. Our Platform does not participate in the creation of User Content. Users must ensure their User Content complies with these Terms.

4.3. By default, the Platform’s models may be trained or improved using User Content and may use such training for Outputs generated for all Users. We can use your Content worldwide to provide, maintain, develop, and improve our Platform and Services, comply with applicable law, enforce our terms and policies and keep our Services safe.

4.4. If a User subscribes to a Tier that excludes data use for training, that User’s Content will not be used to train, tune, or otherwise improve the Platform or to inform other Users’ Outputs; it will be processed only to deliver that User’s own Outputs, unless the User deletes such Content or otherwise requests its removal. To opt-out from having your User Content used to train our models, you may need to upgrade your Tier.

4.5. The Platform may personalize Outputs by analyzing the User’s past interactions, preferences, prompts, usage patterns, or other Content previously submitted by the User. Such personalization constitutes automated processing and is used solely to tailor the relevance, style, or usefulness of the Outputs delivered to the User. The Platform’s models perform these operations algorithmically and without human intervention. Users may opt out of personalization or profiling at any time by indicating so through the settings for the respective Content. If a User opts out, the Platform will no longer use the User’s specific interaction history or preferences for the purpose of customizing Outputs.

4.6. Users bear the responsibility for the User Content uploaded on the Platform. You must take all prudence not to upload any User Content that contains illegal or offensive material or violates these Terms nor any other guidelines posted in the Platform and statement undertaken by the User with regard to the User Content, nor Content that is intended to manipulate, exploit, or interfere with the proper functioning of the Platform’s models, including attempts to jailbreak, reverse engineer, or circumvent filters, safety systems, or usage limits or use Content seeking to obtain professional, medical, financial, or legal advice in a manner that would misrepresent the Outputs as certified, expert, or authoritative.

4.7. By uploading any User Content to the Platform, you represent, warrant, and agree that all User Content submitted in the Platform does not infringe third-party rights, including but not limited to confidentiality obligations, applicable copyright, unfair competition, and data protection laws; where the User Content includes the images and/or any other personal data of third parties, you are solely responsible to ensure that the third parties have granted their free and informed consent to have their data included in the User Content, before uploading it; you are responsible to provide appropriate proof when so requested.

4.8. We shall in no manner be liable for any damage caused as a result of the User Content uploaded by any User, as well as in case it deletes any User Content uploaded in violation of these Terms. The Platform bears no responsibility for any loss or damage that may be caused to any third party and/or User due to specific User Content.

5.1. Access and use of the Sophea Nous Platform is provided exclusively for lawful, personal, and non-commercial use.

5.2. The User is prohibited from using Sophea Nous and/or the Outputs generated in a way that:

• violates applicable national or international law, including, indicatively, legislation on personal data protection, intellectual property, criminal law, or consumer protection,

• aims at reverse engineering, decompilation, disassembly, modification, reproduction, exploitation, or unauthorized republication of the platform, code, or service results,
• uses automated means (bots, scrapers, scripts) for mass content extraction, infrastructure overloading, or violation of the permitted method of use.

5.3. We have the right (not the obligation) under these Terms and the applicable laws to check and suspend temporarily or permanently (delete), any Content following reports about infringing behavior and/or content. We use automated systems and human review to identify and address content that violates our Terms. If we become aware of violations, we may remove or restrict Content, limit your access to Services and Features, or suspend or terminate your Account.

5.4. If you believe that any Output, or other material displayed or generated through the Platform is unlawful, infringes rights, or is harmful, offensive, harassing, or otherwise inappropriate, you may submit a notice to the Company using the reporting tools provided on the Platform or by contacting us at the designated notice address. To request removal of specific Content, send a clear, substantiated notice identifying the content and legal basis. The notice must include: (i) your contact details; (ii) the user Content; (iii) your signature; (iv) a good-faith statement that the use is unauthorized; (v) sufficient information for us to identify the content and understand the basis of your concern and (vi) a statement made under penalty of perjury on your authority to act for the rightsholder. We will also remove/suspend content following orders by a Court or Competent Authority.

5.5. The Company has no obligation to retain any User Content or Outputs beyond what is necessary to provide the Services or comply with applicable law. The Platform may, at its discretion, delete or remove User Content or Outputs at any time, including in cases of inactivity, account suspension, termination, or storage limitations. Users are solely responsible for maintaining their own copies and backups of any User Content or Outputs they wish to preserve. The Company shall not be liable for any loss, deletion, or corruption of User Content.

5.6. Violation of the above terms provides the Company with the right to temporarily or permanently suspend the User Account, delete User Content, and, if required, report to competent authorities. We reserve the right, but do not bear any obligation, to monitor service use for security and regulatory compliance reasons.

6.1. The Platform may allow Users to connect or synchronize their accounts with third-party services (such as Google Account, Google Drive, Google Cloud, Microsoft OneDrive, SharePoint or other external platforms) in order to enable the import, access, or processing of User Content stored in such external environments. By enabling such integrations, the User expressly authorizes the Platform to access, retrieve, process, and store information from the connected third-party account for the purpose of delivering the Services and generating Outputs.

6.2. Users are solely responsible for ensuring that they have the lawful right, permissions, and internal authorizations (including company policies, confidentiality obligations or data protection rules) to connect their third-party accounts to the Platform. Any Content imported from a third-party account shall be deemed User Content and subject to these Terms. The Company is not responsible for any unauthorized or improper integrations made by the User.

6.3. Integrations are also subject to the terms and policies of the third-party provider (e.g., Google Terms of Service, Google API Services User Data Policy, Microsoft Services Agreement). Users are responsible for reviewing and complying with such third-party terms. The Company has no control over and assumes no liability for the practices, availability, security, or performance of third-party services.

6.4. Users may disconnect their third-party accounts at any time through their account settings. Disconnecting an account does not delete previously imported User Content; such content remains subject to these Terms until deleted by the User.

7.1. All content, technological infrastructure, and elements of the Sophea Nous platform—including, indicatively but not limitedly, source and compiled software, machine learning algorithms, knowledge base, AI model architecture, training data, interface layout and design, graphics, icons, logo, trade names, as well as any generated content (text, responses, messages) hosted in the Platform — constitute intellectual and/or industrial property of the Company or its lawfully licensed suppliers and partners.

7.2. The protection of these elements is governed by Greek and EU legislation on intellectual property, trademarks, trade secrets, and unfair competition, as well as international conventions, as applicable and in force.

7.3. The user acquires no rights whatsoever over the intellectual or other elements of the service, beyond the non-exclusive, limited, temporary, and personal license for use, granted for private use purposes, in accordance with these Terms. The generated content (Outputs) of Sophea Nous is not owned or under distinct and exclusive intellectual property of the User and may be reused by the system in similar contexts.

7.4.

You may not modify, translate, decompile, reverse engineer, or create derivative works from any software or accompanying documentation provided by the Company or its licensors.

In case of unauthorized use, any license granted by the Company terminates.

7.5. All other trademarks, registered trademarks, product names, and company names or logos that may appear on the Platform are the property of their respective owners.

8.1. The Sophea Nous service provides information and content generated automatically through artificial intelligence systems, trained to process natural language and respond to queries based on prior learning and patterns. Users acknowledge that, due to the statistical and probabilistic nature of artificial intelligence systems, Outputs may contain inaccuracies, omissions, outdated information, biases, or other errors inherent in machine-generated content. Responses are provided exclusively for general informational and supportive purposes, and do not constitute a substitute for specialized professional advice from a certified legal, medical, financial advisor, or other professionals. Users bear full responsibility for cross-checking, verifying, and evaluating the information they receive from the platform. Any decisions, actions, or omissions taken by the User based wholly or partly on Outputs are made entirely at the User’s own risk.

Except as expressly stated in these Terms, the Platform does not provide and expressly disclaims warranties, conditions, or undertakings of any kind in relation to the Services, either express or implied, including, without limitation, warranties of merchantability and fitness for a particular purpose. No advice or information, whether oral or written, obtained through the Platform will create any warranty not expressly stated or incorporated herein. Without limiting the foregoing, the Company, its subsidiaries, its licensors, and affiliates, do not warrant that any Content is accurate, true, reliable, correct, or complete.

9.2. The Platform may contain hyperlinks (links) to third-party websites.

However, we do not guarantee that the Platform will be available without interruption and without errors. We are not liable, though, if for any reason, negligence included, despite the maintained security measures adopted by us, the operation of the Platform is interrupted or access to the Platform or the User Accounts becomes difficult and/or impossible, or if viruses or other harmful software is identified and transmitted to the terminals of the Users, or if third unauthorized parties intervene in any way to the Content and operation of the Platform making the use of it difficult or causing problems to its proper function. Moreover, we are not liable if the Platform is not accessible for reasons beyond our control as well as for reasons due to technical or other failure of the backbone network or for reasons of force majeure or incidental facts.

10.1. We may decide to modify, suspend or discontinue available Tiers, Pricing, Services and Features to improve, add, or remove functionalities, on our sole discretion. Material changes to Tiers affecting Pricing, including the provision of specific Services and/or Features, and/or reducing functionalities (“Changes”) will take effect upon at least thirty (30) days’ prior notice and will not apply during any prepaid, committed term unless (i) functionally equivalent alternatives are provided, or (ii) User opts in through specific prompt provided through the Platform or via e-mail. It is clarified that continued use of the Platform, after specifically opting-in to the Changes, will be considered as acceptance of the Changes, that will apply immediately upon first use of the Platform following the opt-in.

10.2. We retain the right to modify these Terms, at any time, without justification, partially or in total, e.g. to refer to our newest Features and Services, to update our Pricing or reflect newer policies. If the changes to the Terms materially affect the way you interact with the Platform, we will provide fifteen (15) days’ notice -or more, if so provided for in these Terms- before applying the new Terms. Notice will be provided through the Platform or to the e-mail address you have provided. In some cases, the User may be prompted to opt-in to the new Terms.

11.2. We appreciate your feedback, and you agree that we may use it without restriction or compensation to you.

11.3. Severability: In the event that a term is found to be abusive or is canceled, this does not affect the other terms hereof which remain valid and binding on both of us. If any part of the Terms is found to be invalid, void, or unenforceable (including any provision in which we exclude our liability to you), the enforceability of any other part of the Terms will not be affected -all other terms will remain in full force and effect. In any event, where it is possible for a term/sub-condition or part of a term/sub-condition to be considered separately in order to make the remaining part valid, the term will be interpreted accordingly. Otherwise, we both agree that the term should be corrected and will be interpreted to approximate as closely as possible the original meaning of the term/sub-term in accordance with the law.

11.4. No Waiver: Any delay by either party in exercising some or all of its rights under these terms and conditions shall not impair or waive that right, which may be exercised at any time thereafter at the reasonable discretion of the beneficiary.

12.2. In case we cannot work out the dispute among us, we mutually agree to try and resolve any disputes arising with regard to these Terms amicably and in good faith. To that effect, we will attempt to solve their differences through mediation, by recourse to the flexible dispute settlement/mediation process of Law 4512/2018. This, however, does not affect either our rights or your rights to initiate judicial proceedings at any time before, during, or after the mediation process.

12.3. These Terms are governed and interpreted in accordance with Greek law. For any dispute arising from or in relation to the Terms, the Courts of Athens (Central Seat) have jurisdiction.
