Hey HN,

I’ve been building Shortenr — a modern, all-in-one link tool designed for creators, marketers, crypto users, and privacy-focused users.

It includes: • End-to-End Encrypted File Sharing (client-side, using AES-256) • Smart Link Shortening (geo/device targeting, A/B tests, UTM builder) • Poll Links (gather user feedback from a short link) • One-Time & Expiring Links (perfect for stealthy content) • Link-in-Bio Pages with full analytics

Everything’s built with privacy in mind — even file uploads are never stored in plaintext, and most features work without needing an account.

I’m 15 and built this solo with TypeScript + Next.js + Prisma + PostgreSQL.
