💡 BeyondLife: Third-Party Digital Will Application 💻

✨ Welcome to BeyondLife, an innovative prototype app that transforms the concept of a digital legacy into a simplified interactive experience. The project aims to explore the future of posthumous data management, making it simple and easy to set up, manage, and securely share a digital will. 🔒

This repository provides an open-access implementation related to our research paper submitted to WWW25 (International World Wide Web Conference 2025). It contains a lightweight prototype that demonstrates key functionalities discussed in the paper below.

⚠️ Disclaimer

This repository contains no source code—it serves solely as a demonstration resource for the BeyondLife prototype hosted via Expo, and pre-built Android and iOS bundles are also available for local installation.

🔍 BeyondLife is designed for research and concept exploration. It is not intended for production use or the management of sensitive personal data. Evaluate and enjoy this app as a prototype, not as a finalized product.

❗️ Demo Version Details:

The current demo version is a simplified version of the full application. It currently supports setting up a digital will for X (formerly Twitter), while support for Gmail and Google Drive will be included in the full version.

To ensure data security for demo users (e.g., avoiding accidental deletion of personal tweets), the demo allows users to link their private Twitter accounts but does not use the authorized token to retrieve or modify any data. Instead, predefined sample tweets are provided for testing purposes.

However, the cloud storage link is fully functional in this demo version. During interactions, BeyondLife will upload encrypted data to the demo user’s cloud storage.
