📡 Nearby Transfer

Share pastes instantly with nearby devices — no links or QR codes required.

🚀 How to Use

1. Open the Transfer page from the PasteDB Home or Landing page (Transfer).

2. Make the receiving device discoverable:

   • 📱 Mobile: Hold three fingers on the screen for 3 seconds or press and hold the "Be Discoverable" button for 3 seconds.
   • 💻 Desktop / Laptop: Press and hold the "Be Discoverable" button for 3 seconds.

3. The receiving device becomes discoverable for 10 seconds.

4. On the sender's device, open the paste you want to share and click Nearby Share.

5. Select the discovered device from the list and confirm the transfer.

6. The paste is sent instantly to the selected device.

📍 Location Permission

Nearby Transfer requires location permission on both the sender and receiver for reliable nearby device discovery. Your location is used only to improve discovery accuracy and is not shared with other users.

🎯 Why PasteDB?

PasteDB began as a personal learning project with a simple goal: build a modern, production-style web application while exploring real-world software development.

But now the metrics (5/9/26)

• 👥 User Base: 12,000+ active users per month (28-day rolling average).📊
• Analytics: Tracked and verified via Google Analytics 4 (GA4).

Instead of creating another basic CRUD project, I wanted to build something that people could actually use every day. Along the way, PasteDB became a platform for experimenting with new ideas, improving my development skills, and solving practical problems.

Through this project, I gained hands-on experience with:

• 🔐 Authentication and authorization
• 🌐 Official Python SDK
• 🍃 MongoDB database integration
• 📁 Image uploads
• 🛡️ Secure content sharing and privacy features
• 🔒 End-to-End Encryption (E2EE)
• 📡 Nearby device transfer
• ⚡ Code execution and syntax highlighting
• 🎨 Responsive UI/UX design
• ☁️ Cloud deployment with Netlify and Render
• 🔗 Frontend-backend communication
• 📊 Analytics, SEO, and performance optimization

PasteDB continues to evolve as I learn new technologies and build features that make sharing code, notes, and files faster, simpler, and more secure.
