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. Access and Use of the Platform

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.

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 you 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. Tiers, Fees and Payment

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. Content

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.

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.

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.
