ChatDok GmbH is a company incorporated under the laws of the Federal Republic of Germany.

ChatDok operates digital healthcare technology and AI-supported services for patients, healthcare professionals, healthcare organizations, and other authorized users.

Our services may evolve over time as new technologies, clinical programs, integrations, and features are introduced.

2.1 ChatDok Platform

Depending on your location, eligibility, and the service you use, ChatDok may provide access to:

• conversational medical AI;
• general health information and education;
• personalized health support;
• symptom and health tracking;
• medication and lifestyle support;
• multimodal interaction, including voice or image functionality where available;
• digital care coordination;
• post-discharge and longitudinal care support;
• remote monitoring functionality;
• clinical or care-team communication;
• healthcare provider or care-program services;
• research or clinical validation programs; and
• other digital healthcare features introduced from time to time.

Not all services or features are available in every country or to every user.

3.2 AI-supported information is not a diagnosis

Information provided through ChatDok's AI systems is intended to support health information, education, communication, and care coordination. Unless expressly stated otherwise within a regulated healthcare service:

• ChatDok does not provide an independent medical diagnosis;
• AI-generated information should not be treated as a definitive medical opinion;
• AI outputs may be incomplete, inaccurate, or unsuitable for an individual situation;
• AI outputs should not replace professional medical assessment; and
• you should consult a qualified healthcare professional when you have concerns about your health.

You remain responsible for seeking appropriate professional medical care.

ChatDok uses artificial intelligence, including generative AI, machine learning, conversational systems, and other computational technologies.

AI systems can make mistakes.

ChatDok therefore designs its systems with measures intended to improve reliability, including appropriate safeguards, validation processes, structured information sources, and human oversight where applicable.

However, no AI system can guarantee that every output will be complete, correct, current, or appropriate for a particular individual.

You should not rely solely on an AI-generated response when making a medical decision.

Where a ChatDok service connects you with a physician or healthcare professional, the healthcare professional remains responsible for the medical assessment and clinical decisions within the applicable treatment relationship.

The ChatDok App provides access to selected digital healthcare and AI-supported features. Depending on availability, these may include:

• conversational medical support;
• personalized health information;
• symptom tracking;
• medical image analysis;
• voice interaction;
• health documentation;
• medication-related support;
• appointment or care coordination;
• educational content; and
• other digital healthcare functions.

Features may vary according to your country, account type, regulatory requirements, clinical program, and technical availability.

ChatDok may add, modify, suspend, or discontinue individual features where reasonably necessary for technical, regulatory, clinical, security, or business reasons.

Where ChatDok facilitates communication between you and an independent physician or healthcare professional, the physician or healthcare professional remains responsible for the medical services they provide.

The medical treatment relationship is established between you and the relevant healthcare professional where applicable.

ChatDok may provide the technical infrastructure supporting that interaction, but does not assume the professional responsibilities of the treating physician.

The healthcare professional is responsible for:

• medical assessment;
• diagnosis;
• treatment decisions;
• prescriptions;
• medical documentation; and
• other professional obligations applicable to their service.

Any medical service provided through a third-party healthcare professional may be subject to separate terms, fees, professional rules, and insurance arrangements.

ChatDok-Navigator is an AI-supported digital care coordination service designed to help healthcare organizations support patients after discharge and throughout longitudinal care pathways.

Depending on the program, Navigator may support:

• personalized post-discharge guidance;
• patient check-ins;
• medication and appointment reminders;
• patient-reported symptoms and information;
• recovery tasks;
• health education;
• care coordination;
• communication with care teams;
• structured escalation workflows; and
• other functions configured by the participating healthcare organization.

Navigator may be provided as part of a healthcare program operated by a hospital, health system, insurer, or other organization. In such cases, the relevant healthcare organization remains responsible for the applicable clinical pathway and clinical decisions.

Navigator is intended to support care coordination and communication. It does not independently replace a physician or other qualified healthcare professional.

ChatDok-Heart is an AI-supported cardiovascular care platform that may include conversational support, remote monitoring, personalized care plans, patient engagement, and clinical decision-support functionality.

Certain ChatDok-Heart features may be made available as part of clinical validation, research, or healthcare programs.

Where a service is part of a clinical study or research program, additional information, eligibility requirements, informed-consent documents, study protocols, and participant terms may apply.

Clinical research participation is governed by the applicable study documentation and does not automatically create a general entitlement to a particular ChatDok service.

ChatDok develops and evaluates healthcare AI through research, clinical validation, and real-world healthcare programs.

Some features described on our website may be:

• under development;
• undergoing clinical validation;
• available only to selected users;
• available only within research programs; or
• not yet commercially available.

Descriptions of research objectives or anticipated benefits do not constitute a guarantee of clinical effectiveness or future product availability.

Where a study or clinical validation program applies, the applicable study documentation takes precedence over general website descriptions.

To use certain ChatDok services, you may need to create an account. You agree to:

• provide accurate and complete information;
• keep your information up to date;
• maintain the confidentiality of your login credentials;
• use your own account;
• not share your credentials with unauthorized persons; and
• notify ChatDok promptly if you suspect unauthorized access.

Unless a specific service states otherwise, account registration is intended for users who are at least 18 years old and legally capable of entering into contracts.

Where ChatDok provides services for minors through an authorized parent, guardian, healthcare organization, or specific program, additional requirements may apply.

Where available, ChatDok may provide functionality allowing an authorized person to manage certain services or health information on behalf of another individual, including a child.

Such functionality may be subject to additional consent, authorization, identity verification, and data-protection requirements.

You may only access or manage another person's health information where you are legally authorized to do so.

When using ChatDok, you agree to:

• use the services only for lawful purposes;
• provide accurate information;
• follow reasonable instructions relating to your healthcare program;
• protect your account credentials;
• not misuse, disrupt, or interfere with the platform;
• not attempt to circumvent security measures;
• not upload malicious software or harmful content;
• not impersonate another person;
• not use ChatDok to provide unauthorized medical services;
• not reverse engineer or attempt to extract proprietary models or source code; and
• not use ChatDok's AI outputs as a substitute for professional medical judgment where professional care is required.

You must not use ChatDok's AI services to:

• generate fraudulent medical documentation;
• impersonate healthcare professionals;
• make unauthorized clinical decisions on behalf of another person;
• interfere with clinical or healthcare workflows;
• attempt to obtain another person's confidential health information;
• circumvent access controls or security mechanisms;
• use the service for unlawful purposes; or
• systematically extract, copy, reproduce, or commercially exploit ChatDok's AI outputs or systems without authorization.

Where supported, you may upload or provide information such as:

• symptoms;
• health measurements;
• medical documents;
• medication information;
• photographs;
• laboratory results;
• other health-related information; and
• messages or other communications.

You are responsible for ensuring that information you provide is accurate to the best of your knowledge and that you have the necessary rights or authorization to provide it.

You retain applicable rights in content that you submit.

You grant ChatDok the rights necessary to process, store, transmit, display, and otherwise use that content to provide the requested service and for the purposes described in our Privacy Policy.

Additional rights may apply where information is processed for research or clinical validation, as described in the relevant consent documentation.

Health information is particularly sensitive personal data.

ChatDok processes personal and health-related information in accordance with applicable data-protection law and our Privacy Policy. Depending on the service, processing may include:

• account administration;
• delivery of digital healthcare services;
• communication with healthcare professionals;
• care coordination;
• security and fraud prevention;
• service improvement;
• technical support; and
• research or clinical validation where an appropriate legal basis and, where required, additional consent applies.

For detailed information about data processing, retention, recipients, international transfers, and your rights, please refer to our Privacy Policy.

ChatDok implements technical and organizational measures designed to protect personal information against unauthorized access, alteration, loss, or disclosure.

However, no internet-based service can guarantee absolute security.

You are responsible for maintaining the security of your device and account credentials.

If you believe that your account has been compromised, please contact us promptly at: [email protected]

We aim to make ChatDok services available reliably and continuously.

However, uninterrupted availability cannot be guaranteed. Services may temporarily be unavailable because of:

• maintenance;
• software updates;
• security measures;
• technical failures;
• infrastructure outages;
• third-party dependencies;
• network failures;
• regulatory requirements; or
• circumstances beyond our reasonable control.

We may also modify or discontinue individual features where reasonably necessary.

ChatDok may integrate with or provide access to third-party services, including healthcare providers, pharmacies, app stores, infrastructure providers, healthcare systems, or other partners.

Third-party services may be subject to separate terms and privacy policies.

Unless expressly stated otherwise, ChatDok is not responsible for independent third-party services or contracts between you and those third parties.

Where available, ChatDok may provide technical functionality that supports interactions between patients, healthcare professionals, and pharmacies.

ChatDok does not itself become the contracting party for a medical treatment or pharmacy transaction merely because the transaction is technically facilitated through ChatDok.

Where a physician issues a prescription, the prescription is issued by the physician under the applicable legal and professional framework.

Where a pharmacy supplies a medicine or other product, the relevant purchase contract is between the patient and the pharmacy unless expressly stated otherwise.

Availability of these services varies by country and applicable law.

All intellectual property rights in the ChatDok platform and its underlying technology, including software, source code, models, AI architectures, interfaces, databases, trademarks, logos, designs, text, graphics, videos, and other proprietary materials are owned by or licensed to ChatDok unless otherwise indicated.

Subject to these Terms, ChatDok grants you a limited, non-exclusive, non-transferable right to use the services for their intended personal or authorized purpose.

You may not reproduce, distribute, modify, sell, sublicense, reverse engineer, or commercially exploit ChatDok's proprietary materials without prior written permission, except where mandatory law provides otherwise.

Where ChatDok provides AI-generated content, you may use that content for the intended purpose of the relevant service.

Because AI-generated information may contain errors, you should review important information appropriately and seek professional advice where necessary.

If you provide feedback, suggestions, or ideas regarding ChatDok, you agree that ChatDok may use that feedback to improve its services without creating an obligation to compensate you, provided that such use complies with applicable data-protection requirements.

The price applicable to a particular ChatDok service will be communicated before you are required to pay for that service.

Some ChatDok services may currently be available free of charge to consumers.

Other services, clinical programs, or third-party healthcare services may involve fees.

Where fees apply, the applicable price, payment terms, cancellation rights, and any additional conditions will be presented before the relevant contract is concluded.

Medical services provided by independent healthcare professionals may be subject to separate charges and reimbursement arrangements.

Where you are a consumer and applicable law grants you a statutory right of withdrawal, the applicable statutory provisions apply.

Where required, information concerning your withdrawal rights, including any exceptions or early-expiration conditions applicable to digital services, will be provided before the relevant contract is concluded.

A withdrawal from a ChatDok digital service does not automatically cancel a separate contract with a physician, pharmacy, insurer, or other healthcare provider.

You may stop using ChatDok at any time.

Where your account includes a deletion or account-closure function, you may use that function or contact us at: [email protected]

ChatDok may suspend or terminate access where reasonably necessary, including where:

• you materially breach these Terms;
• your use creates a security risk;
• continued use would violate applicable law;
• fraudulent or abusive activity is suspected; or
• a service is discontinued.

Where required by applicable law, we will provide appropriate notice.

Termination does not affect rights or obligations that by their nature should continue after termination.

Healthcare technology, legal requirements, security standards, and clinical programs evolve over time.

We may therefore modify, update, add, or discontinue services or features.

Where a change materially affects your contractual rights or obligations, we will provide notice where required by applicable law.

We may update these Terms from time to time.

The current version will be made available through the ChatDok website or application.

Where changes require your consent under applicable law, we will request that consent.

Where applicable law permits changes without individual consent, we may update the Terms after providing the notice required by law.

If you do not agree with a material change, you may stop using the affected service, subject to any applicable contractual obligations.

ChatDok is liable in accordance with applicable law.

Nothing in these Terms excludes or limits liability where such exclusion or limitation is prohibited by law. In particular, limitations of liability do not apply to liability arising from:

• intentional misconduct;
• gross negligence where legally applicable;
• injury to life, body, or health;
• mandatory statutory liability; or
• other circumstances for which liability cannot legally be excluded or limited.

To the extent legally permitted, ChatDok shall not be liable for indirect or consequential damages arising from the use of the services.

ChatDok is not responsible for medical decisions made independently by users or for services provided by independent healthcare professionals, except to the extent that applicable law provides otherwise.

ChatDok's technology may support healthcare professionals and healthcare organizations, but it does not independently assume the clinical responsibility of the healthcare professional or organization operating a particular care pathway.

Clinical decisions remain with appropriately qualified healthcare professionals where professional medical judgment is required.

For Navigator and other enterprise healthcare programs, the applicable healthcare organization remains responsible for defining and operating its clinical pathways, escalation processes, and clinical governance.

ChatDok operates internationally and certain services may be available in multiple countries.

Healthcare regulations, professional requirements, reimbursement systems, and availability of digital healthcare services differ between jurisdictions.

A service available in one country may not be available, appropriate, or legally permitted in another.

You are responsible for complying with applicable local requirements when accessing ChatDok from outside Germany.

If you have a question, complaint, or concern about ChatDok, please contact:

We will review complaints and support requests in accordance with applicable law and our internal procedures.

Where a particular healthcare service is provided by an independent physician or healthcare organization, complaints relating to the medical service may need to be addressed directly to the relevant provider.

To the extent required by applicable law, information concerning consumer dispute-resolution mechanisms will be provided separately.

ChatDok is not voluntarily participating in consumer dispute-resolution proceedings unless expressly stated otherwise.

These Terms are governed by the laws of the Federal Republic of Germany, subject to mandatory consumer protection provisions applicable in the country in which you reside.

Where you are a consumer residing in another EU Member State, nothing in these Terms limits mandatory rights granted to you by the laws of your country of residence.

The UN Convention on Contracts for the International Sale of Goods does not apply.

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions remain in effect to the extent permitted by law.

The invalid provision will be replaced or interpreted in accordance with the applicable legal requirements.

These Terms, together with the applicable Privacy Policy, Cookie Policy, and any additional terms specifically applicable to a particular service, form the contractual framework governing your use of ChatDok.

Where a specific service has additional terms, those terms take precedence over these general Terms to the extent of any conflict.
