Documentation & Privacy
Everything you need to know about how ZeroServer processes your data securely.
Our Architecture
ZeroServer was built with one core philosophy: Developer tools should not be data traps.
Most online formatters and decoders send your sensitive payloads (like API responses, JWTs, and database passwords) to a backend server to process them. This exposes your proprietary data to server logs, third-party tracking, and potential breaches.
ZeroServer completely eliminates this risk. Every single tool on this website is written in JavaScript/TypeScript and executes entirely within the Document Object Model (DOM) of your own web browser. When you click "Format" or "Decode", the math happens on your CPU, not ours.
Security Guarantees
Zero Server Logs
We do not have a backend database. We cannot see your data.
No Cookies
We do not use tracking cookies to monitor your behavior.
Local Storage Only
If we save user preferences (like Light/Dark mode), it stays in your browser's LocalStorage.
Hardware Entropy
Our generators use your OS's native crypto APIs for true randomness.
Supported APIs
| Tool | Native API Used |
|---|---|
| JSON Formatter | JSON.parse() / JSON.stringify() |
| Base64 Encoder | btoa() / atob() |
| URL Encoder | encodeURIComponent() |
| UUID & Passwords | window.crypto.getRandomValues() |
