🔐 Secured File Share

Secured File Share is a lightweight, privacy-first file sharing platform built with Streamlit and Cloudinary. It allows users to securely upload any file format and generate private links and QR codes for sharing. Files are automatically deleted after a user-defined time and are protected with passwords — no login or signup required.
