General Terms and Conditions for the LongevLab Application

1.1 The Agreement

These General Terms and Conditions (referred to as "Terms," "GTC," or the "Agreement") constitute a comprehensive, legally binding contract between the end-user ("User," "you," or "your") and LongevLab ("LongevLab," "we," "us," or "our"). This Agreement meticulously governs your access to, and all use of, the entire LongevLab suite of services. This suite of services (collectively, the "Services") includes, but is not limited to: the LongevLab iOS mobile application (the "App"); any associated websites, including the primary domain longevlab.com and its subdomains; all related content, text, graphics, data, and information; features such as data analysis and visualization tools; software, including all updates, upgrades, and new versions; and all functionalities provided now or in the future by LongevLab. This Agreement is designed to establish a clear understanding of our mutual rights and obligations.

1.2 Acceptance of Terms

Your relationship with LongevLab and your authorization to use our Services are strictly conditional upon your acceptance of this Agreement. By taking any action to engage with our Services—including downloading the App from the Apple App Store, installing it on your device, accessing any feature, or otherwise using the Services in any capacity—you affirmatively acknowledge that you have diligently read, fully understood, and unconditionally agree to be legally bound by every provision of this Agreement. This includes the terms of our Privacy Policy (available for review at longevlab.com/privacy), which is not a separate document in spirit but is an integral part, incorporated herein by this reference. If you do not agree with any part of these Terms or the Privacy Policy, or if you are unwilling to be bound by them, you are expressly prohibited from accessing or using the Services. In such a case, you must immediately cease all use, uninstall the App from your device, and refrain from accessing our websites or any other part of the Service.

1.3 Key Disclaimers and Principles

Your relationship with LongevLab is founded on the pillars of transparency, user empowerment, and trust. To that end, we draw your immediate and focused attention to two foundational principles that define our Service and are elaborated upon throughout this Agreement. Understanding these principles is crucial to understanding the nature of the Services we provide.

1. NOT MEDICAL ADVICE: The Services are designed exclusively for informational, educational, and general wellness purposes. LongevLab is a technology company, not a medical provider. The App is not a medical device, has not been approved by the FDA, EMA, or any other regulatory body for such a purpose, and does not provide medical advice, diagnosis, or treatment. It is not a substitute for the expertise, judgment, and care of qualified medical professionals. Please see the comprehensive disclaimer in Section 10.
2. "ZERO-KNOWLEDGE" PRIVACY COMMITMENT: The Services have been meticulously engineered with a unique, privacy-centric "zero-knowledge" architecture. This is a core tenet of our philosophy. We are committed to the principles of data minimization and absolute user control. This means we are architecturally prevented from accessing your most sensitive health data, which is processed exclusively on your personal device unless you explicitly and knowingly authorize its transmission to a third-party service for a specific, user-initiated feature. Section 4 provides a detailed explanation of our data-handling practices.

1.4 Modification of Terms

The digital landscape and legal requirements evolve, and LongevLab reserves the right, in its sole and absolute discretion, to modify, amend, supplement, or update these Terms at any time. We are committed to transparency in this process. We will provide notice of any changes by posting the revised Terms on our website and within the App, and we will update the "Last Updated" date at the top of this Agreement to reflect the date of the changes. For any modifications we deem "material"—that is, changes that significantly alter your rights or obligations—we will make a reasonable effort to provide you with advance notice. This may include an in-app pop-up notification, a message on the App's home screen, or other conspicuous means. Your continued access to or use of the Services following the effective date of such modifications shall constitute your conclusive acceptance of the revised Terms. If you do not agree to the modified Terms, your sole and exclusive remedy is to terminate your relationship with LongevLab by ceasing all use of the Services and uninstalling the App.

2.1 Service Description

The LongevLab Service is a sophisticated personal wellness and longevity platform, meticulously designed to empower you with accessible, understandable, and personalized insights into your health and well-being. The App functions as your personal data analysis tool, enabling you to track, visualize, correlate, and better comprehend your health data over time. The ultimate goal of the Service is to provide you with actionable, informational insights that can help you make more informed decisions about optimizing your nutrition, sleep, and exercise habits for the purposes of improved general wellness and longevity.

2.2 Core Features

The Services currently include, but are not limited to, the following core features, which may be updated and expanded over time:

1. Wearable Data Integration: With your explicit, revocable consent managed through the iOS HealthKit permissions system, the App can securely read and analyze a wide array of health metrics tracked by your compatible wearable devices (such as an Apple Watch, Oura Ring, Whoop, etc.). This includes data points like Heart Rate Variability (HRV), Resting Heart Rate (RHR), detailed sleep staging (Deep, Light, REM, Time Awake), wrist temperature, blood oxygen levels, and more.
2. Biomarker Tracking: The App provides a robust interface for you to digitize and track your personal health records. You can manually input values or use our AI-assisted scanning feature (via your device's camera) to extract biomarker values from documents like blood test results. This allows you to monitor trends in key markers such as Cholesterol (LDL, HDL), Vitamin D, HbA1c, hs-CRP, and others over time, transforming static reports into dynamic, longitudinal graphs.
3. Personalized Insights: The App's on-device intelligence analyzes the data you provide access to, generating informational scores, trend analyses, and general wellness insights related to your sleep quality, recovery status, and daily physical effort. These insights are presented in an easy-to-understand format, intended to highlight potential correlations and areas for lifestyle improvement.
4. Artificial Intelligence (AI) Chat: The App includes an interactive chat feature powered by a sophisticated third-party AI model. This feature allows you to ask natural language questions and receive contextualized information based on the specific data streams (e.g., activity data, sleep data) you choose to share with the AI model for the purpose of that query.

3.1 Age Requirement

The Services are intended solely for access and use by individuals who are 18 years of age or older. This age restriction is in place because the Services involve the processing of sensitive health information and require the legal capacity to enter into a binding contract. By accessing or using the Services, you represent and warrant that you meet this age requirement and possess the full legal authority and capacity to enter into and abide by this Agreement. The Services are not designed for, intended for, or directed at children under the age of 18. We do not knowingly collect, solicit, or store personal information from individuals under 18. If we become aware that we have inadvertently collected such information, we will take immediate and commercially reasonable steps to delete it from our systems.

3.2 Service Operation without User Accounts

In line with our commitment to privacy and data minimization, the LongevLab App is designed to function without requiring you to create a personal user account, register an email address, or manage login credentials. All of your data, settings, and usage history are tied directly and exclusively to your specific physical iOS device. This design choice significantly enhances your privacy, as it eliminates a central database of user accounts that could be a target for data breaches. Consequently, there are no account credentials for you to remember or for us to secure. However, this also means that you are solely responsible for the physical and digital security of the device on which the App is installed. If your device is lost, stolen, or damaged, any data stored within the App that has not been backed up through other means (like iCloud backups of the device itself) may be permanently lost. LongevLab has no way to recover this data for you.

4.1 Our Commitment to Your Privacy

Your privacy is the absolute bedrock of our Service and the guiding principle of our engineering philosophy. Our "zero-knowledge" commitment is not a marketing term; it is a technical reality of our architecture. It means we are structurally and intentionally prevented from accessing, viewing, or storing your most sensitive, identifiable health data. We strictly adhere to the principles of data minimization (collecting only what is absolutely necessary) and user control (ensuring you are always in the driver's seat). This section defines the legal and technical boundaries of our data handling. For a complete and detailed description of our privacy practices, please review our comprehensive Privacy Policy.

4.2 Data Processed Locally on Your Device

We want to be unequivocally clear: the following categories of data are processed exclusively on your personal iOS device within the secure sandbox of the App. This data is never transmitted to, stored on, viewed by, or otherwise accessed by LongevLab' servers or personnel. It remains entirely under your control, protected by your device's native security features, such as the Secure Enclave and your passcode/biometric authentication.

1. Apple HealthKit Data: Any and all data the App reads from the Apple HealthKit API, which you explicitly authorize through the granular iOS permission system. This includes, but is not limited to, sensitive metrics such as Heart Rate Variability (HRV), Resting Heart Rate (RHR), detailed sleep stages (e.g., Deep, REM, Light), active and resting energy, steps, workout data, and respiratory rate. All analysis, calculations, and insight generation using this data occur locally on your device's processor.
2. Manually-Entered Health Data: Any and all biomarker values and other health information that you manually type into the App. The ongoing processing, visualization, historical trending, and storage of this highly sensitive information happens entirely on your device's local storage.

4.3 Data Processed by Third-Party AI Models with Your Explicit Consent

To provide advanced, computationally intensive features, LongevLab integrates with best-in-class third-party AI models. The use of these specific features is entirely optional and requires your explicit, informed consent before any data leaves your device. LongevLab acts as a conduit in these instances and does not itself process or store the data transmitted.

1. PDF Biomarker Scanning: When you choose to use the feature to scan a document (e.g., a PDF of your blood test results), the image or file of that document is transmitted directly from your device to a third-party AI model for Optical Character Recognition (OCR) and data extraction. This data is processed by the third-party provider, not by LongevLab, for the sole purpose of identifying and returning the structured biomarker values (e.g., "Cholesterol: 200 mg/dL") to the App on your device, after which it is stored locally as described in Section 4.2. Before using this feature for the first time, you will be presented with a clear consent screen explaining this process.
2. AI Chat Feature: When you engage with the AI chat feature, your chat queries and any health or activity data you explicitly select for inclusion are transmitted to a third-party Large Language Model (LLM) to provide contextualized responses. This processing is performed by the third-party AI provider, not by LongevLab. This data may include your sleep duration, step count, or heart rate, but will not include sensitive biomarker data unless you grant separate, explicit consent for that specific purpose within the chat interface. Your consent is required for each session or query where you wish to include such data.

4.4 Limited Data We Collect and Store

To operate and improve the Service, we collect a minimal set of non-personally identifiable or pseudo-anonymous data on our secure servers. This data is essential for basic functionality and service enhancement. This includes:

1. Device and Usage Information: We collect the model of the device you use (e.g., "iPhone 15 Pro") when you sync data with Apple HealthKit. This is used in an anonymized and aggregated form to analyze data accuracy from different sources (e.g., comparing data fidelity from different wearable brands) and to refine our algorithms and troubleshoot compatibility issues.
2. Opt-in Crash and Bug Reports: If the App encounters a software error, you may be prompted to share a diagnostic report with our development team. Sharing this report is strictly optional (opt-in) for each individual instance. These reports are anonymized and stripped of any personally identifiable health information before transmission and are used exclusively for diagnosing and fixing technical problems.

4.5 Anonymized and Aggregated Data

You grant LongevLab a right to use the limited, non-personally identifiable data we collect (as defined in Section 4.4) in a de-identified, anonymized, and aggregated form for legitimate business purposes. These purposes are strictly limited to improving the performance, accuracy, and features of the Services, conducting high-level statistical analysis (e.g., "what percentage of users use Feature X?"), and for internal research and development. At no point will this aggregated data contain any information that could be used to personally identify you or be traced back to an individual User. This right does not, and will never, extend to the sensitive health data processed locally on your device as described in Section 4.2.

5.1 Grant of License

Subject to your full and ongoing compliance with this Agreement, LongevLab grants you a limited, worldwide, non-exclusive, non-sublicensable, non-assignable, and non-transferable license. This license permits you to download, install, and use the App on a single iOS device that you personally own or control. This use is strictly for your personal, non-commercial enjoyment and benefit in accessing the Services. "Non-commercial use" explicitly prohibits any form of resale, service bureau use, or using the App to provide paid services to others.

5.2 Prohibited Uses

Your right to use the Services is strictly conditioned on your adherence to this Agreement and all applicable laws. You agree that you will not, and will not attempt to, directly or indirectly, or encourage or assist any third party to:

1. Use the Services for any commercial purpose, including but not limited to the resale of the Service, offering health coaching based on the App's output for a fee, or any data derived from it.
2. Copy, modify, adapt, translate, create derivative works of, reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, underlying ideas, algorithms, structure, or organization of the App or any part of the Services.
3. Use any manual or automated means, including robots, spiders, scrapers, or other data-mining tools, to access, monitor, or extract data from the Services (this includes data scraping or web harvesting).
4. Use the Services for any illegal, fraudulent, or unauthorized purpose, or in any manner that violates any applicable local, state, national, or international law or regulation.
5. Attempt to surreptitiously build a user profile based on collected data or attempt, facilitate, or encourage others to identify anonymous users or reconstruct user profiles.
6. Introduce any viruses, Trojan horses, worms, logic bombs, or other malicious or technologically harmful code into the Services, or otherwise interfere with, disrupt, or create an undue burden on the servers or networks connected to the Services.
7. Use the Services to harass, abuse, stalk, threaten, defame, or otherwise infringe or violate the rights of any other party.
8. Circumvent, disable, or otherwise interfere with any technological measure or security-related feature implemented by LongevLab or any of our providers to protect the Services.

6.1 Ownership of Your Data

LongevLab unequivocally acknowledges and agrees that you retain full, complete, and exclusive ownership of your personal data and any information, data, text, or other materials you manually input, upload, or submit to the Service ("User Content"). This Agreement does not grant us any ownership rights, title, or interest in or to your User Content. We are merely a custodian of the software that allows you to manage it on your device.

6.2 Responsibility for User Content

You are solely and entirely responsible for all User Content that you provide to the App. This includes the responsibility for its legality, reliability, accuracy, and appropriateness. You represent and warrant that you have all necessary rights to provide such User Content (e.g., you are the rightful owner of the medical documents you scan) and that it is accurate, complete, and does not violate any applicable laws or infringe upon the rights of any third party. LongevLab has no obligation or responsibility to review, verify, or validate the accuracy of any User Content you provide. Inaccurate User Content may lead to misleading or incorrect informational insights from the App.

6.3 License to LongevLab

By providing User Content to the Services, you grant LongevLab a limited, non-exclusive, royalty-free, worldwide license to use, reproduce, modify, and display such User Content strictly and solely for the purpose of operating, providing, and improving the Services to you, on your device. This license is narrow and purely functional. For example, it allows the App on your phone to process your onboarding data to calculate and display personalized ranges, or to render your biomarker data in a graph. This license does not grant us the right to use your User Content for promotional, advertising, or any other commercial purpose, a key distinction from many other platforms. This license exists only as long as the App is installed and the data resides on your device.

6.4 Feedback

If you voluntarily choose to provide us with any feedback, comments, ideas, bug reports, or suggestions for improvements to the Services ("Feedback"), you acknowledge and agree that such Feedback is provided without any expectation of confidentiality and is non-proprietary. You hereby grant LongevLab a perpetual, irrevocable, worldwide, royalty-free, fully paid-up, sublicensable, and transferable license to use, incorporate, modify, commercialize, and otherwise exploit such Feedback for any purpose whatsoever, without any restriction or compensation to you.

7.1 Apple HealthKit

The App's ability to read data from the Apple HealthKit repository is entirely dependent on the explicit permissions you grant through your iOS device's native operating system. You maintain full and granular control over these permissions and can grant, deny, or revoke them for specific data types at any time via the Health or Settings app on your device. LongevLab is not responsible for the accuracy, availability, completeness, or security of data stored within the Apple HealthKit database itself, as that is managed by Apple and your other connected applications. Our interaction is read-only and strictly governed by your consent.

7.2 Artificial Intelligence (AI) Features

The AI-powered features (including Chat and PDF Biomarker Scanning) are advanced tools that are subject to the following critical terms, which you accept by choosing to use them:

1. Third-Party Provider and Disclaimer of Output: You acknowledge that these features are powered by a third-party Large Language Model (LLM) provider (e.g., OpenAI's GPT models, Anthropic's Claude models, or similar services). The content, recommendations, and other information generated by the AI ("Output") are for informational and educational purposes only. AI technology is rapidly evolving and may contain errors, inaccuracies, biases, or misleading information. The Output is not medical advice and is not a substitute for consultation with a qualified professional. You must use your own independent judgment and critical thinking before relying on or acting upon any Output. LongevLab has no control over the Output and bears no liability for it.
2. Consent to Data Transmission: By using the AI features, you explicitly consent to the transmission of certain data to the third-party LLM provider to enable the feature's functionality. This includes your chat queries, any health data you explicitly select to provide context for the chat, and the contents of any scanned documents for biomarker analysis. This consent will be requested clearly before the first use of each feature.
3. Third-Party Terms and Data Deletion Limitation: Once your data is transmitted to the third-party LLM provider, it becomes subject to that provider's terms of use and privacy policy. LongevLab does not control the data once it leaves our systems for this purpose. You acknowledge and agree that LongevLab cannot retrieve or delete data that has been sent to the third-party LLM provider. The ability to delete that data, if any, is governed by your relationship with that third party. We strongly encourage you to review the terms and privacy policies of our AI provider before using these features.

7.3 Future Third-Party Services (Forward-Looking Clause)

To support our mission of democratizing access to health insights, the Services may evolve to include directories or platforms that facilitate your connection with independent third-party offerings. This may include, but is not limited to, licensed medical professionals and their practices ("Doctor Network") and vendors of health-related products, supplements, or services ("Product Marketplace"). This clause governs your use of any such future services:

1. Facilitation, Not Provision: You acknowledge that LongevLab' role in such instances is solely that of a neutral technology platform and facilitator. We do not provide medical services, sell physical products, or directly offer third-party services.
2. No Endorsement or Liability: We do not endorse, guarantee, or control the quality, accuracy, legality, safety, or efficacy of any advice, services, or products provided by these independent third parties. LongevLab is not an agent for, and is not a party to, any transaction or relationship you enter into with a third party found through our Service. You are responsible for your own due diligence, including verifying credentials and reading reviews. LongevLab shall not be liable for any loss, damage, or harm of any kind incurred as the result of any such dealings.

8.1 Payment Terms

Access to the Services or certain premium features may require a one-time purchase fee or a recurring subscription fee ("Fees"). All applicable Fees, including the currency and amount, will be clearly and conspicuously presented to you through the Apple App Store's In-App Purchase interface before you complete a purchase. By providing a payment method to the App Store and confirming the purchase, you represent and warrant that you are authorized to use it.

8.2 Billing and Automatic Renewal

If you purchase a subscription-based plan, your subscription will automatically renew at the end of each billing cycle (e.g., monthly or annually) for a successive term of the same duration. You authorize Apple's App Store to charge your designated payment method for the renewal term at the then-current non-promotional rate. You may manage or cancel your subscription at any time directly within your Apple ID account settings in the App Store. To avoid being charged for the next billing cycle, you must cancel your subscription at least 24 hours before the renewal date. All Fees are non-refundable, except as required by applicable law or as expressly permitted by the Apple App Store's policies.

8.3 Future Monetization

LongevLab reserves the right to introduce new features, content, or services that may be subject to additional or different fees. This may include, but is not limited to, transaction fees or commissions for services facilitated through the future Doctor Network or Product Marketplace, or fees for premium reports or advanced analytics. Any such fees will be clearly disclosed to you before you elect to use such features or services, and your purchase will be processed through the App Store.

9.1 Termination by User

You may terminate this Agreement at any time and for any reason. The termination is effected by uninstalling the App from your iOS device and ceasing all use of the Services. As we do not maintain user accounts, no further action is required on your part to terminate the agreement. Deleting the App will also delete the locally stored data, unless it is part of a device backup.

9.2 Termination by LongevLab

LongevLab reserves the right to suspend or terminate your access to the Services, at our sole discretion, without notice or liability, for any reason, including but not limited to a breach of this Agreement. For example, if we have reason to believe you are using the app for prohibited commercial purposes or attempting to reverse-engineer our software, we may take technological steps to disable your access. Upon termination, all licenses and rights granted to you in this Agreement will immediately cease.

14.1 For Users Residing in the United States

1. Governing Law: This Agreement and any dispute arising from it shall be governed by and construed in accordance with the internal laws of the State of Delaware, without regard to its conflict of law principles.
2. Mandatory Binding Arbitration: PLEASE READ THIS SECTION CAREFULLY AS IT AFFECTS YOUR LEGAL RIGHTS. YOU AND LONGEVLAB AGREE THAT ANY AND ALL DISPUTES, CLAIMS, OR CONTROVERSIES ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE SERVICES WILL BE RESOLVED EXCLUSIVELY BY FINAL AND BINDING ARBITRATION, RATHER THAN IN COURT. The arbitration will be administered by the American Arbitration Association ("AAA") in accordance with its Consumer Arbitration Rules. The Federal Arbitration Act will govern the interpretation and enforcement of this section.
3. Class Action Waiver: YOU AND LONGEVLAB AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING. Further, the arbitrator may not consolidate more than one person's claims and may not otherwise preside over any form of a representative or class proceeding.

14.2 For Users Residing in the European Union or the United Kingdom

1. Governing Law and Jurisdiction: If you are a resident of the European Union or the United Kingdom, this Agreement shall be governed by the laws of Ireland. This choice of law does not deprive you of the protection afforded to you by provisions that cannot be derogated from by agreement by virtue of the law of your country of residence. You may be entitled to bring a claim in the courts of your country of residence.
2. Online Dispute Resolution: The European Commission provides for an online dispute resolution platform, which you can access here: https://ec.europa.eu/consumers/odr. LongevLab does not commit to nor is it obliged to use an alternative dispute resolution entity to resolve disputes with consumers.
