About Me
A passionate self-taught developer on a mission to make the internet safer.
Bishnu Kartik Sah
Privacy-First Developer
I'm a 19-year-old self-taught developer and +2 Science graduate from Kathmandu, Nepal. I completed my higher secondary education in the Science stream and then dove headfirst into the world of programming — teaching myself Python, AI development, and software design all on my own.
Every product I build is designed to work reliably without collecting personal data or sending information to external servers. I believe in vibecoding— where creativity meets code — and I'm on a mission to make the internet a safer, more productive place, one extension at a time.

Privacy Trust Center
Transparency is not optional — it's fundamental. Here's how I protect your data.
No Tracking
Zero analytics, zero cookies, zero tracking pixels. Your activity is never monitored.
No External Servers
Everything runs locally on your device. No data is ever sent to external servers.
No Data Collection
No personal data is collected, stored, or transmitted. Period.
Minimal Permissions
Each extension requests only the exact permissions it needs — nothing more.
Privacy Checklist
Every extension meets these standards
