Story

Built an offline encryption tool for people who don't trust cloud services or hardware wallets.

Paranoid Qrypto runs completely offline (air-gapped). You type your seed phrase on an offline device, and it encrypts it using Argon2id + AES-256-GCM. The encrypted file can be stored anywhere USB, cloud, printed as QR code without exposing your keys.

Why this was build: Hardware wallets cost $100-200 and are single points of failure * Cloud solutions require trusting a third party * Paper backups have no protection if found

Technical details: * Runs in browser with no server calls * All encryption happens locally * Open source tools on GitHub: integrity-auditor, airgap-bridges (BTC/ETH/XRP) * Three tiers: Essential ($99), Advanced ($199), Ultimate ($299)
