Technical Privacy Standard
Traditional online developer tools require uploading files or pasting API tokens to a server, presenting major confidentiality risks. At Zynocode Labs, we solve this by executing all calculations locally inside your browser sandbox.
How We Guarantee Complete Data Sovereignty
Our utility tools bypass the server entirely. When you paste database configuration logs, input code scripts, or upload documents, the processing occurs strictly in-memory on your CPU using browser runtime environments.
Cryptographically Secure Randomness
For utilities like the Password Generator, we utilize the browser's native Web Crypto API (window.crypto.getRandomValues) to harvest high-entropy system-level randomness, ensuring keys cannot be predicted by software calculators.
In-Browser File Re-serialization
Our PDF merger, splitter, and compressor use pdf-lib as a local parser. The document streams are converted into standard ArrayBuffer objects in RAM. Unused tags and fonts are stripped, compiling a new PDF document entirely offline.
Canvas Raster Scaling
Image Resizing, Cropping, and Compression utilize the HTML5 Canvas 2D Context API. The browser decodes JPEGs or PNGs to a raw canvas buffer, performs math scaling or quality quantization locally, and exports a compressed file via the browser's download manager.
XSS Sanitized Markdowns
To prevent script injection during markdown preview rendering, we route the compiled HTML output through DOMPurify in the browser window, stripping malicious `onerror` handlers or event scripts before insertion in the DOM.
Network Audits & Zero Logs
You can verify our security standards at any time:
- Open your browser Developer Tools (F12 or Ctrl+Shift+I).
- Navigate to the Network tab.
- Paste text or upload a document inside any of our tools and click execute.
- Notice that no outbound HTTP requests are emitted to any external API endpoints or databases. All computation is processed on your device.
