INTRODUCTION

Rejuve Tech LLC-FC (RejuveAI) is conducting a research study to support the discovery of aging biomarkers and the development of AI-powered strategies to optimize human healthspan. Rejuve Tech is not a healthcare provider or covered entity under HIPAA. However, we follow strict privacy and data protection standards to safeguard your information.

We are asking you to consider being a part of this study because you are an adult aged 18 or over who is using the Rejuve Longevity app and may be willing to contribute health-related data to this research project. We expect about 10,000 people around the world to participate in this study. If you agree to be in the study, your participation is expected to be ongoing, with no fixed end date, as this is a long-term observational study. There are no required in-person visits; all participation occurs through the app or online, and you may withdraw at any time.

The purpose of this study is to contribute to a global, decentralized research effort aimed at understanding and optimizing human aging and healthspan. The study, called the International Longevity Research Database (ILRD), collects long-term health data through the Rejuve Longevity mobile application to help identify biomarkers of aging and train artificial intelligence (AI) models that support personalized health strategies.

Study subjects will contribute health-related data through the app and web platform. This includes self-reported lifestyle and health information, data from connected wearable devices, and when available—clinical and biological data such as laboratory biomarkers and biological age test results (e.g., DNA methylation). Submitting clinical data is strongly encouraged, as it improves both research value and the accuracy of insights provided.

Your participation in the study is expected to be ongoing, with no fixed end date, as the project aims to collect long-term (longitudinal) data. There are no in-person visits required; all data is submitted remotely at your convenience.
