PLEASE READ THIS SECTION CAREFULLY.

Not Medical Advice. The information provided through the Services, including all AI-generated responses, articles, condition guides, biomarker references, treatment information, and community content, is for general informational and educational purposes only. It is not intended to be, and should not be construed as, medical advice, diagnosis, or treatment.

No Doctor-Patient Relationship. Use of the Services does not create a doctor-patient relationship between you and ChatDys LLC or any of its employees, contractors, or AI systems. ChatDys is not a licensed medical provider.

AI Limitations. Our AI assistant can make errors, may have outdated information, and cannot account for your complete medical history, current medications, allergies, or individual circumstances. AI responses should always be verified with a qualified healthcare provider.

Community Content. Posts and comments in the community forum are shared by other patients and caregivers, not medical professionals. Community content reflects personal experiences and opinions and should not be treated as medical guidance.

Emergency Situations. If you are experiencing a medical emergency, call 911 or your local emergency number immediately. Do not use the Services in an emergency situation.

Always Consult a Healthcare Provider. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Never disregard professional medical advice or delay in seeking it because of something you have read or received through the Services.

Moderation. We reserve the right to remove any content that violates our Community Guidelines or these Terms, and to suspend or ban accounts that repeatedly violate our policies, without prior notice.

Medical Misinformation. Posting content that is demonstrably false and could endanger the health or safety of other users (e.g., claiming a substance cures a condition without scientific basis, discouraging evidence-based medical treatment) is strictly prohibited and may result in immediate account termination.

No Professional Advice. You may share your personal experiences but may not present yourself as a medical professional or provide advice that could be construed as professional medical, legal, or financial guidance unless you are a licensed professional doing so in an appropriate context.

Our Content. The Services and all content created by ChatDys LLC, including the AI system, platform design, condition guides, articles, biomarker database, and treatment information, are owned by or licensed to ChatDys LLC and are protected by copyright, trademark, and other intellectual property laws. You may not reproduce, distribute, or create derivative works from our content without our written permission.

Content Responsibility. You are solely responsible for the content you post. You represent that you have all rights necessary to grant the license above and that your content does not violate any third-party rights or applicable law.

De-identified Research. We may use de-identified, aggregated data derived from user-generated content for research, analytics, and platform improvement purposes. No individual user will be identifiable in such aggregated data.

Your use of the Services is also governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Services, you consent to the collection and use of your information as described in the Privacy Policy.

The Services integrate with third-party services including Stripe (payments), Terra API (wearables), xAI/Grok (AI), and others. Your use of these third-party services is subject to their respective terms of service and privacy policies. We are not responsible for the practices of third-party services.

Links to external websites or resources are provided for convenience only. We do not endorse and are not responsible for the content, products, or services on external sites.

Voluntary Submission. You may voluntarily upload raw DNA data files (e.g., from 23andMe, AncestryDNA, or similar direct-to-consumer genetic testing services) to use the Genetics features of the Services. Uploading genetic data is entirely optional and not required to use any other part of the platform.

How We Use Your Genetic Data. Uploaded DNA files are processed solely to match your variants against our curated database of GWAS (genome-wide association study) variants relevant to dysautonomia and related conditions. We do not sell, share, or transfer your raw genetic data to any third party, including insurance companies, employers, law enforcement, or pharmaceutical companies, except as required by law.

Manual Variant Entry. You may also manually enter specific rsIDs and genotypes without uploading a file. Manually entered variants are stored and treated with the same protections as uploaded genetic data.

Storage & Security. Genetic data files are stored encrypted at rest and in transit. Access is restricted to the minimum necessary personnel for platform operation. We apply industry-standard security controls to protect this sensitive data category.

No Clinical Interpretation. Variant matching results provided by ChatDys are for informational and educational purposes only. They do not constitute clinical genetic counseling, medical diagnosis, or treatment recommendations. Results should be reviewed with a qualified genetic counselor or healthcare provider.

Deletion Rights. You may delete your uploaded genetic data and all manually entered variants at any time through your account settings (Genetics → My Variants → Delete). Upon deletion, raw file data is permanently removed from our systems within 30 days. De-identified, aggregated statistical data derived from your variants (with no individual identifiability) may be retained for research purposes.

Affiliate Links. The My Variants page may display affiliate links to direct-to-consumer genetic testing services (e.g., 23andMe, AncestryDNA). We may receive a commission if you purchase through these links. Affiliate relationships do not influence how we handle your genetic data.

Research Use. With your explicit consent (obtained separately), de-identified genetic variant data may be contributed to anonymized research datasets to advance understanding of dysautonomia and related conditions. You may withdraw this consent at any time.

Not a HIPAA Covered Entity. ChatDys LLC is not a healthcare provider, health plan, or healthcare clearinghouse as defined under the Health Insurance Portability and Accountability Act of 1996 (HIPAA). As such, the information you share with ChatDys is not protected health information (PHI) subject to HIPAA's Privacy Rule or Security Rule in the traditional sense.

Health Data Protections We Apply Voluntarily. Although not legally required to comply with HIPAA, we voluntarily apply HIPAA-inspired data protection practices to all health-related information you share with us, including:

• Encryption of health data at rest (AES-256) and in transit (TLS 1.3)
• Strict access controls limiting employee access to health data on a need-to-know basis
• Audit logging of access to sensitive health records
• Data minimization — we collect only the health data necessary to provide the Services
• No sale of health data to third parties under any circumstances
• User rights to access, correct, export, and delete their health data

If You Are a Healthcare Provider. If you are a licensed healthcare provider using ChatDys to assist patients, please note that you remain responsible for your own HIPAA compliance obligations. Do not enter identifiable patient information into ChatDys without appropriate patient authorization.

State Health Privacy Laws. Some U.S. states (including California, Washington, and Nevada) have enacted health data privacy laws that may apply to your use of the Services. We comply with applicable state health privacy requirements. For more information, see our Privacy Policy.

GDPR Health Data. If you are located in the European Economic Area, health data (including genetic data) is classified as a "special category" under the General Data Protection Regulation (GDPR) and receives heightened protection. We process such data only with your explicit consent and in accordance with Article 9 of the GDPR. You have the right to withdraw consent at any time without affecting the lawfulness of processing prior to withdrawal.

Termination by Us. We reserve the right to suspend or terminate your account at any time, with or without notice, for any reason, including but not limited to violation of these Terms. We will make reasonable efforts to notify you before termination except where immediate action is necessary to protect the safety of users or the integrity of the Services.

Governing Law. These Terms are governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles.

Informal Resolution. Before filing any formal legal claim, you agree to attempt to resolve the dispute informally by contacting us at [email protected]. We will attempt to resolve the dispute within 30 days.

Arbitration. If informal resolution fails, any dispute arising from or related to these Terms or the Services shall be resolved by binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court, except that either party may bring claims in small claims court if they qualify.

Class Action Waiver. You agree to resolve disputes with us on an individual basis and waive any right to participate in a class action lawsuit or class-wide arbitration.

Exceptions. Either party may seek emergency injunctive relief in a court of competent jurisdiction to prevent irreparable harm pending arbitration.

We may modify these Terms at any time. When we make material changes, we will notify you by email and by posting a notice on the Services at least 14 days before the changes take effect. Your continued use of the Services after the effective date of the revised Terms constitutes your acceptance of the changes.

If you do not agree to the revised Terms, you must stop using the Services and may terminate your account.
