Inspiration
Today, almost everything in our lives is digital — emails, cloud storage, social media, subscriptions, and even financial accounts. But if something happens to a person, their digital data often gets locked forever. Families struggle to access important information, and valuable digital assets are lost. This real-world problem inspired us to create Digital Legacy Vault — a way to protect and pass on a person’s digital life safely and responsibly.

What it does
Digital Legacy Vault helps users store their important digital information in one secure place. Users can choose trusted people who should get access to this data if they are no longer able to manage it themselves. The platform focuses on privacy, security, and controlled access so that digital assets are shared only when truly needed.

How we built it
We built the project as a full-stack web application. The frontend is made using HTML, CSS, and JavaScript to keep the interface clean and easy to use. The backend is developed in PHP, which handles user authentication and logic. We used MySQL to store data securely and implemented password hashing and prepared statements to protect user information.

Challenges we ran into
Security was our biggest challenge. We had to make sure user data was protected at every level. Handling authentication, preventing duplicate accounts, and managing database errors took time and testing. Debugging backend issues and designing a scalable database structure were also challenging, especially under hackathon time pressure.

Accomplishments that we’re proud of
We’re proud that we built a fully working and secure system from scratch. The authentication flow works reliably, data is stored safely, and the platform solves a real and meaningful problem. Most importantly, we created a strong base that can be expanded in the future.

What we learned
This project taught us the importance of security, privacy, and clean backend development. We learned how real-world applications handle sensitive data and why careful database design matters. It also improved our teamwork, debugging skills, and confidence in building full-stack applications.

What’s next for Digital Legacy Vault
In the future, we plan to add features like automated inactivity detection, nominee notifications, and stronger verification methods such as blockchain. We also aim to develop a mobile version and integrate legal documents to make Digital Legacy Vault a complete digital inheritance solution.
