Architecture

How it actually works.

A few deliberate steps that create both magic and trust.

1. You type a URL

The path encodes the tool, every parameter, and the language. /ja/integer/5/1/100 — that’s the complete state.

2. The server reads the path

Regex parses the path into named variables. Query strings are silently discarded. The URL you see is the complete truth.

3. The server ships a shell

Parameters are whitelisted, clamped, and sanitized. Metadata, hreflang for 16 languages, and JSON-LD structured data are built and delivered.

4. Your browser generates randomness

crypto.getRandomValues() — the same cryptographic engine that secures online banking. The server is already done.

🔒 Good to know
dice83 never stores personally identifiable information. However, every URL you visit on any website travels through infrastructure beyond your control — your internet provider, DNS resolver, and network intermediaries can observe which addresses you request. This is how the internet works everywhere, not specific to Dice83. For additional privacy, consider encrypted DNS or a trusted VPN.
Privacy

Privacy first.
Own your results.

Every result is generated inside your browser and stays on your device. The server delivers the tool; your device creates the outcome.

∅

Zero data storage

dice83 keeps no user database. No accounts, no profiles, no result history on any server. Clean architecture from the ground up.

⊛

Browser-powered randomness

Your browser’s Web Cryptography API generates every result. Your device does the work; the server is already finished.

⌂

Results stay on your device

The server delivers the page. Your browser creates the outcome. Results live in your device’s memory and localStorage, under your control.

Zero tracking footprint

No tracking cookies. No analytics pixels. No fingerprinting scripts. Your activity leaves no trace on our side.

Good to Know
Your results live in your browser’s memory and in localStorage on your device. If you use browser extensions, some may interact with page content across all websites you visit — reviewing your installed extensions periodically is a good general practice for a comfortable browsing experience.
