ProtectedShare is a privacy-first, zero-knowledge open-source web application designed for sharing encrypted secure notes, code snippets, .env files (EnvShare alternative), and managing a synchronized private notepad (ProtectedText alternative).

All encryption and decryption happen directly in your browser using the native Web Crypto API (AES-256-GCM) before any transmission. Keys and raw master passwords never touch the server, creating a mathematical guarantee of privacy.

Key Features:
- Encrypted Secure Notes: Create secure notes with custom durations and password protection.
- One-Time Secrets & EnvShare: Share .env files, API keys, and configurations with burn-after-read auto-destruction.
- Synchronized Notepad: A secure personal scratchpad syncing across devices anonymously.
- Zero-Tracking: No cookies, trackers, or registrations.
- High Performance: Built on Cloudflare Workers and D1 database for global sub-millisecond edge resolution.
