for the software and web browser extension provided by Newt, s.r.o.

Effective: 3 April 2026

1. Introductory Provisions

1.1. These General Terms and Conditions (hereinafter the "GTC") govern the rights and obligations between the software provider, Newt, s.r.o., Company ID No.: 23532947, with its registered office at Křejpského 1529/3, Chodov, 149 00 Prague, registered in the Commercial Register, and the user of the software application, which includes in particular a web browser extension, mobile applications (e.g. for iOS and Android), a web interface (client portal), an application programming interface (API), MCP (Model Context Protocol) server integrations and related features (hereinafter the "Service").

1.2. By installing the Service, registering a user account or purchasing a subscription (issuing a license key), the user confirms that they have read these GTC and agree to them.

1.3. License arrangement: By installing the Service, the Provider grants the User a non-exclusive, non-transferable and time-limited license to use the Service solely for the User's own needs, for the duration of the subscription or other period of authorized use. The User is not entitled to copy, modify or distribute the Service, or reverse engineer its source code, except where such restriction is not permitted by mandatory legal provisions.

1.4. Maintenance and updates: The Provider does not guarantee uninterrupted availability of the Service, compatibility with all third-party services or the release of new features. The Service is provided on an "as is" basis. This does not affect the Provider's obligation to provide consumers with necessary updates and to remedy defects to the extent required by mandatory legal provisions.

2. Nature of the Service and Technical Operation

2.1. The Service operates primarily as a technical interface between the User's web browser, third-party APIs and, in certain plans, also the Provider's infrastructure. For the purposes of technical optimization, faster response times, limiting redundant requests, securing the Service and reducing costs, User content, including selected page text, an entire page or a substantial part thereof, may be processed, transmitted and stored either directly by AI providers or by the Provider, depending on the selected plan, the specific feature and the technical mode of the Service.

2.1.1. Page content processing modes:

• a) Direct BYOK mode – selected page content is sent directly from the User's browser to the provider of the AI model whose API key the User has configured.
• b) Provider-mediated mode – selected page content, an entire page or a substantial part thereof may be temporarily processed by the Provider's infrastructure for the purpose of providing the Service feature, routing, security, prevention of misuse, caching or displaying the result, and subsequently transferred to the AI provider or evaluated by another technical method used by the Provider.
• c) Pre-cached analysis mode – the Service may display to the User a previously created analysis result stored on the User's device or on the Provider's server, including a result matched on the basis of a URL match, content hash, fingerprint or another technical identifier.

2.1.2. Full or substantial page analysis: In some features, the Service may submit the entire textual content of the displayed page or a substantial part thereof for analysis, not only the excerpt expressly selected by the User. The User acknowledges that such content may include personal data, confidential information, copyrighted content or other protected information, and bears sole responsibility for having valid authorization to submit such content for analysis.

2.1.3. Risk of outdated and mismatched results: If pre-cached analysis mode is used, the User may be shown a result created earlier for identical or similar content. The User acknowledges that such result may be outdated, incomplete, inaccurate or may not correspond to the current content of the page in real time. The Provider does not guarantee that a pre-cached result will correspond to the current version of the analyzed page.

2.1.4. Functionality and interoperability: The Service is provided as an extension for a supported web browser. Proper operation may require a stable internet connection, a compatible browser version, an active user account and, in the relevant plans, a valid API key from a supported AI provider. The current scope of supported environments, plans and integrations may be specified on the Provider's website or in the Service interface.

2.2. BYOK model and other integration modes: The User acknowledges that some variants of the Service require the User to have their own valid third-party API key. In other plans, processing may be provided through the Provider's infrastructure or integrations selected by the Provider. Contractual and data relationships between the User and the provider of a specific AI API are governed by the terms of that provider; where content is transmitted through the Provider's infrastructure, these GTC and the Privacy Policy also apply.

2.3. Separation of liability: The Provider is not liable for the functionality, availability, correctness of outputs or changes in the terms and conditions or prices of third-party APIs. The costs of operating the API are paid by the User directly to the relevant API provider, unless otherwise stated in a specific plan.

2.4. Authorization to process content and cache: The User grants the Provider a non-exclusive, royalty-free and territorially unlimited authorization to automatically process, store, technically evaluate, transmit and redisplay content submitted by the User, solely to the extent necessary for the technical provision of the Service, including routing, security, prevention of misuse, caching, deduplication of requests and provision of pre-cached results. This authorization does not in itself establish any right of the Provider to use the content beyond the stated scope; any further use is governed by the Privacy Policy or the description of the specific plan or feature.

2.5. Technical operation of the cache: To increase speed, reduce costs and limit redundant requests, the Service may use both local and server-side cache. The cache may store previously created analysis results (or an abbreviated version thereof), content hashes or fingerprints, URLs, metadata and other technical identifiers. If the Service finds a corresponding record in the cache, it may display that stored result for optimization purposes in preference to performing a new live analysis. Warnings regarding the risks associated with the possible outdatedness of results displayed in this way and the related exclusion of the Provider's liability are governed by Sections 2.1.3, 3.6 and 6.1 of these GTC.

2.6. History and web interface: If the Service offers a feature for saving the history of checks and making it accessible across devices (e.g. through the web interface), the User acknowledges that, for this purpose, submitted data and analysis results are stored on the Provider's infrastructure and permanently linked to the User account. The User bears full responsibility for what data they submit to their history for permanent storage (with regard to the prohibition in Section 3.4).

2.7. Application Programming Interface (API) and system integrations (MCP): Within selected plans, the Provider may enable automated access to the Service via an API or protocols for integration with LLMs (e.g. MCP). The following rules apply to such access:

• a) Access protection: The User is responsible for keeping their access keys and tokens confidential and bears full responsibility for all traffic carried out through them.
• b) Traffic limits and Fair Use: Automated access must not disproportionately burden the Provider's infrastructure. The Provider is entitled to apply request limits (rate limits) and, in the event of overload or misuse, to limit or block access to the API/MCP without notice.
• c) Prohibition on resale: Without an express written agreement, it is prohibited to use the API/MCP to create the User's own commercial services, resell results in bulk (white-labeling) or circumvent the limits of the User's plan.
• d) Validity of the GTC: These GTC fully apply to traffic via the API/MCP, in particular the strict prohibition on sending sensitive data (Section 3.4), the rules on liability for content and the exclusion of the Provider's liability.

3. User Obligations, Compliance and Data Security

3.1. Legal responsibility for inputs: The User bears sole and full legal responsibility for all content (texts, data, URLs) submitted for analysis through the Service.

3.2. Compliance with AI service terms (API Providers): The User undertakes that their use of the Service will comply with the terms of use of the AI model provider and with applicable legal regulations. The User must not use the Service to generate illegal content, hate speech, sexually explicit material, malware or for activities that violate the rights of third parties. Without a separate prior agreement with the Provider, the Service must also not be used for prohibited practices under applicable rules on artificial intelligence, in particular social scoring, prohibited manipulative techniques, prohibited biometric use or other use in high-risk areas if such use would require a special regulatory regime.

3.2.1. Custom instructions and prompts: If the Service allows the User to define custom instructions, control mechanisms or assignments for the AI model (so-called prompts), the User bears sole responsibility for their content and safe use. The User undertakes that custom prompts will not be misused to circumvent model safety filters (so-called jailbreaking), to unlawfully extract data or to violate the terms of the AI provider.

3.3. Respecting the rights of analyzed websites (Content Creators): The User represents that they are authorized to access the content of websites that they have the Service analyze. The User is required to respect copyright, license terms and technical restrictions of third-party websites. The Service must not be used for unauthorized data extraction (scraping).

3.4. Prohibition on processing sensitive data: It is strictly prohibited to use the Service to process, analyze or transmit data that contains:

• a) banking secrecy, access passwords, payment card details or other financial information;
• b) special categories of personal data within the meaning of Article 9 GDPR;
• c) classified information, trade secrets of third parties or data subject to a statutory duty of confidentiality, unless the User has appropriate authorization for such processing.

3.4.1. Special caution when analyzing an entire page: If the feature for analyzing an entire page or a substantial part thereof is activated, the User must, before using it, assess whether the relevant page contains any data listed in Section 3.4, confidential information, internal company information, access credentials, data protected by a duty of confidentiality or other content that the User is not authorized to transmit.

3.4.2. Automation and whitelist: If entire-page analysis or pre-cached evaluation is available in automatic mode or through a whitelist, the User must configure these features cautiously and only for domains for which the User reasonably believes that they do not contain the data and information referred to in Section 3.4 or Section 3.4.1.

3.5. The Provider does not proactively monitor content submitted by the User beyond the automated technical processes necessary for the operation, security and caching of the Service. This does not preclude temporary technical processing of content in the modes described in these GTC and in the Privacy Policy.

3.6. Human-in-the-loop obligation: The User acknowledges that the Service uses generative AI and/or pre-cached results, which may contain errors, hallucinations, distortions, outdated information or results that do not correspond to the current content of the page. The User bears sole responsibility for reviewing and verifying outputs. The Provider is not liable for damage caused by relying on an unverified, outdated or inaccurate output.

3.7. Indemnification obligation: The User undertakes to indemnify the Provider in full for any harm, costs, fines, court costs and third-party claims incurred by the Provider as a result of the User's breach of obligations under Sections 3.1 to 3.5 of these GTC. If the User is a consumer, this section applies only to the extent permitted by mandatory legal provisions.

4. Payment Terms, Service Cancellation and Delivery

4.1. The Service is provided in variants that may include a free version (Free) and paid subscriptions. The scope of features of the individual versions and current prices are stated in the Service interface or on the Provider's website.

4.2. Payments may be processed through an external payment gateway (e.g. Stripe). The Provider does not store payment card numbers.

4.3. The tax document (invoice) will be made available to the User for download in the user interface or sent electronically.

4.4. Subscription cancellation: The User is entitled to cancel the subscription at any time. Unless otherwise stated in a specific offer, checkout or individual agreement, cancellation of the subscription takes effect immediately. This does not affect the consumer's rights established by mandatory legal provisions.

4.5. Refunds and cancellation fee: If an already running subscription is cancelled, the User will be refunded the proportional part of the paid amount corresponding to the unused period until the end of the prepaid term. However, the Provider will always retain a fixed non-refundable fee equal to 10% of the originally paid amount (to cover transaction and administrative costs associated with setting up and cancelling the service). This does not affect the consumer's rights arising from defective performance, the right to withdraw from the contract to the extent provided by legal regulations, or other cases where legal regulations require a refund of the full price.

5. Rights Arising from Defective Performance (Complaints)

5.1. The Provider is responsible for ensuring that the Service is properly delivered (made available) to the User and has basic functionality in accordance with these GTC. However, the User acknowledges that, given the technological nature of the Service (see Section 6.2) and its dependence on third parties, uninterrupted availability and error-free operation are not guaranteed. This does not affect the Provider's obligations towards consumers required by mandatory legal provisions (e.g. provision of necessary updates).

5.2. Exclusion of liability for content: To the maximum extent permitted by legal regulations, the Provider is not liable for the factual accuracy, quality, legality or suitability of content generated by a third-party AI model or for the content of a previously stored pre-cached result. This does not affect the consumer's rights arising from defective performance to the extent they cannot be contractually excluded.

5.3. A complaint concerning technical non-functionality or other defects of the Service may be submitted by the User at info@debiasify.cz. The Provider will handle the complaint without undue delay, within a reasonable period and no later than within the time limits established by mandatory legal provisions.

6. Exclusion of Liability and Damages

6.1. Exclusion of liability to the maximum extent permitted by law: To the maximum extent permitted by legal regulations, the Provider is not liable for direct, indirect, incidental or consequential damages arising in connection with the use of the Service. This includes, in particular, damage arising from:

• a) breach of the terms of the AI model provider by the User;
• b) infringement of copyright or terms of use of analyzed websites;
• c) submission of sensitive, confidential or otherwise protected data for analysis, whether knowingly, negligently or automatically;
• d) reliance on a factually incorrect, incomplete, hallucinated, outdated output of the Service, or an output that does not correspond to the current content, including a pre-cached result;
• e) use of User-defined prompts, modified instructions or non-standard control mechanisms that led to the generation of erroneous or prohibited content.

6.2. No warranties: The Service is provided on an "as is" basis. The Provider provides no warranties, express or implied, and in particular does not warrant that the outputs will be accurate, current, complete, continuously available or suitable for the User's particular purpose. This does not affect the rights granted to consumers by mandatory legal provisions.

6.3. Waiver of rights (B2B): If the User is an entrepreneur, the User hereby waives, to the maximum extent permitted by law, the right to compensation for damage, including damage caused by negligence, where such waiver is permitted by legal regulations.

6.4. Limitation of the amount of damage (financial cap): In the event that the waiver of the right to compensation for damage under the preceding paragraph (or any other limitation of liability in these GTC) is found invalid or ineffective by the competent court or other authority, the Provider's total aggregate liability for all claims arising in connection with the Service is limited, to the maximum extent permitted by legal regulations, as follows:

• a) for the paid version, up to the amount actually paid by the User to the Provider for use of the Service during the period of one (1) month preceding the occurrence of the damaging event;
• b) for the free version (Free), up to CZK 50.

7. Personal Data Protection

7.1. The handling of personal data is governed by the document "Privacy Policy".

7.2. If the User uses the Service as an entrepreneur and personal data of their clients, employees or other third parties is processed through the Service on behalf of such User (always with the strict exclusion of data prohibited under Section 3.4 of these GTC), the parties automatically enter into a Data Processing Agreement (DPA) under Article 28 GDPR, exclusively for modes in which the data is processed or transmitted through the Provider's infrastructure. The full text of the DPA is available on the software provider's website and forms an integral part of these GTC. To the extent that Newt acts as a processor, the processing is also governed by this Data Processing Agreement.

8. Withdrawal from the Contract (Consumer Protection)

8.1. The Service constitutes the delivery of digital content or a digital service without a tangible medium.

8.2. If the User is a consumer and requests that the Service be made available before the expiry of the withdrawal period, the User shall provide the Provider with the relevant express consent during the order process and acknowledge the consequences established by legal regulations. If such consent has been duly granted and the required notice has been duly provided, the User acknowledges that their right to withdraw from the contract may cease to exist to the extent provided by legal regulations.

9. Final Provisions

9.1. Governing law: Legal relationships are governed by the laws of the Czech Republic. Rights and obligations not expressly regulated by these GTC are governed in particular by Act No. 89/2012 Coll., the Civil Code, and, if the User is a consumer, also by Act No. 634/1992 Coll., on Consumer Protection, all as amended.

9.2. Jurisdiction: The courts of the Czech Republic have jurisdiction to resolve disputes.

9.3. Out-of-court settlement of consumer disputes: If the User is a consumer, they have the right to out-of-court settlement of any dispute arising from the contract. The entity for out-of-court settlement of consumer disputes is the Czech Trade Inspection Authority.

9.4. Changes to the GTC and changes to the Service: The Provider is entitled to change these GTC or the features of the Service for fair and objective reasons, in particular due to changes in legal regulations, security requirements, technical changes in connections to third-party APIs, prevention of misuse or development of the Service. The User will be informed of material changes reasonably in advance, usually by e-mail or by notice in the Service interface. If a change would result in a material deterioration for a consumer in access to or use of the Service, the consumer has the right to terminate the obligation without penalty to the extent provided by mandatory legal provisions.

9.5. In the event of a conflict between language versions, the Czech version shall prevail.

9.6. Third-party platforms (App Store, Chrome Web Store, Google Play): If the Service is downloaded through platforms such as Apple App Store or Google Play, the User acknowledges that these GTC are entered into only between the Provider and the User, not with the operators of those platforms (e.g. Apple Inc., Google LLC). The platform operators bear no responsibility for the Service or its content and do not provide maintenance or support services. However, the operators of these platforms are entitled (as third parties) to enforce compliance with these GTC.
