If you do not agree with any part of these terms, you may not use the platform. These terms apply to all users, including healthcare professionals ("Clinicians"), clinic administrators ("Admins"), and clients ("Clients").

Service Description

LongevOS is a software-as-a-service platform for longevity and preventive health clinics that provides:

  • Wearable device integration (Apple Health, Garmin, Oura Ring) for continuous health monitoring
  • Secure messaging between clinicians and their clients

Eligibility

LongevOS is available to licensed healthcare professionals and their authorized staff. Client accounts are created by or on behalf of a healthcare provider. You must be at least 18 years of age to create a clinician or admin account. Client accounts for minors must be managed by a parent or legal guardian in coordination with the healthcare provider.

  • You must provide accurate and complete information during registration and keep your profile information up to date
  • You must notify your organization administrator or LongevAI immediately if you suspect unauthorized access to your account

Multi-Tenant Organizations

LongevOS operates as a multi-tenant platform. Each organization has its own isolated data environment. Organization administrators are responsible for managing user access within their organization, including inviting and removing clinicians, configuring AI settings, and ensuring compliance with their local regulations.

Acceptable Use

You agree not to use LongevOS to:

  • Upload, store, or transmit any content that violates applicable laws, including healthcare privacy regulations
  • Attempt to access data belonging to other organizations or users without authorization
  • Reverse-engineer, decompile, or disassemble any part of the platform
  • Use the platform to provide medical advice or treatment outside the scope of your professional license
  • Share your account credentials with unauthorized individuals
  • Interfere with or disrupt the integrity or performance of the platform
  • Use automated scripts, bots, or scrapers to access the platform without prior written consent
  • Upload malicious software, viruses, or any other harmful code

Client Portal

The Client Portal allows clients to:

  • View their health data, biomarker results, and AI-generated insights as approved by their clinician
  • Complete health questionnaires assigned by their healthcare provider
  • Book appointments and manage their schedule with the clinic
  • Communicate securely with their clinician through the built-in messaging system

AI-Generated Content

LongevOS uses artificial intelligence to assist healthcare professionals. By using the platform, you acknowledge and agree to the following:

  • AI Output is Assistive. All AI-generated content (health insights, domain summaries, action plans) is intended as a decision-support tool for qualified healthcare professionals. It does not constitute medical advice, diagnosis, or treatment.
  • Clinician Review Required. AI-generated findings and action plans must be reviewed and approved by a licensed clinician before being shared with clients or used in clinical decision-making.
  • No Guarantee of Accuracy. While we strive for accuracy, AI-generated content may contain errors. LongevAI does not guarantee the completeness, reliability, or suitability of AI outputs for any particular medical purpose.
  • Customization Responsibility. Organizations can customize AI prompts, health domains, and action libraries. The organization and its clinicians are responsible for the clinical appropriateness of their customized configurations.

Data Ownership

  • Your Data Belongs to You. Healthcare organizations retain full ownership of all client health data stored in LongevOS. LongevAI processes this data solely on behalf of and under the instructions of the healthcare provider.
  • License to Use. By uploading data to LongevOS, you grant LongevAI a limited, non-exclusive license to process that data as necessary to provide the services described in these terms. This license terminates when you delete the data or close your account.
  • No Data Selling. LongevAI does not sell, license, or share your data with third parties for marketing, advertising, or any purpose unrelated to providing the LongevOS service.
  • Data Export. You may export your data at any time through the platform's export features or by contacting us at info@longevai.nl. We will provide your data in a structured, machine-readable format within 30 days of your request.

Severability

If any provision of these Terms of Service is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.
