Data

The data category currently holds two utilities — a QR code generator and a random number generator — both small, but distinct in purpose. QR codes encode short strings (URLs, contact details, Wi-Fi credentials, plain text) as scannable images you can drop into print materials, signage, or business cards. The random number generator picks integers in any range, flips coins, and rolls dice using cryptographically secure randomness from the Web Crypto API, which is what makes it suitable for fair selections rather than just informal shuffling.

Both run entirely in your browser. The string you encode in a QR code — a guest-network Wi-Fi password, a personal contact card, an internal URL — never leaves your device, which is exactly the right place for credentials and personal data. The random-number outputs are not logged either, which is what lets them stand up to scrutiny if a draw, raffle, or audit ever needs to be defended after the fact.
