# Pasteport — Cross-Device Sharing + Developer Toolkit

> Pasteport (https://pasteport.zain-imran.com) is a free, privacy-first cross-device sharing platform and complete developer toolkit. It enables users to transfer text, code snippets, files, images, and PDFs across devices (iOS, Android, Windows, macOS, Linux) with a simple 6-digit code or QR scan—without logging in, signing up, or installing software. It also bundles 29 client-side developer utilities that connect directly to your shares, a native desktop application, and a cross-platform CLI tool (v1.1.0).

## Key Capabilities & Features
- **Cross-Device Clipboard Sync**: Instantly pair devices and share content using random 6-digit access codes or direct URL links (`https://pasteport.zain-imran.com/view/<code>`).
- **Mobile QR Code & Camera Scanner**: Enlarge full-screen high-res QR codes, save QR PNGs, and scan QR codes with live device camera viewfinder (`/read`).
- **Offline Download & Viewing Engine**: Local client caching via IndexedDB (`pasteport_offline_db`) enables viewing saved clips and downloading attached files even without an active internet connection.
- **No Login / Zero Friction**: No email, no registration, no tracking. Instant access on all web browsers.
- **4-Character Access PIN Protection**: Optional password protection requiring readers to enter a 4-character PIN before unlocking content, with live real-time screen locking if toggled by the sender at runtime.
- **Self-Destruct PIN / Instant Wipe**: Creators can set a secret deletion PIN or use creator session tokens to permanently wipe Firestore clip metadata and Cloudflare R2 objects immediately.
- **Instant Auto-Expiry Wipe**: Customizable lifespan from 1 to 24 hours (1h, 3h, 6h, 12h, 24h). Expired content is purged immediately from storage upon access or swept daily.
- **Real-Time Live Updates**: Powered by Firestore real-time snapshots; readers can enable "Live Mode" to see the sender's text and attachments update live without page refreshing.
- **Ctrl+V & Global Drop Zone**: Paste screenshots, images, or copied text directly from clipboard with `Ctrl + V` anywhere on the site, or drag & drop files.
- **Sandboxed Cloudflare R2 Storage**: Files and large text payloads (>100KB) are offloaded to Cloudflare R2 object storage with origin isolation, plus direct-to-R2 upload up to 600MB (`/secure`).
