TL;DR: NitroIDE operates entirely within your browser. We do not have servers, we do not track your keystrokes, and we cannot see your code.
NitroIDE is designed with absolute privacy in mind. Because the execution engine is built using HTML5 srcdoc iframes and client-side JavaScript, your code is compiled and executed entirely on your local machine.
Data Storage: Any code you write, files you create in the Virtual File System (VFS), or settings you adjust (like Theme preferences) are stored strictly within your browser's local memory or localStorage. This data never leaves your device.
Data Deletion: Because we do not store your data on external servers, clearing your browser's cache or local storage will permanently delete any unsaved workspaces. Please utilize the Export features within the IDE to save your work to your hard drive.
Analytics & Tracking: We do not use tracking pixels or any form of telemetry. Your coding sessions are your own business.
Third-Party Integrations: If you use the CDN injector to fetch external libraries (like React or Tailwind), your browser will make standard network requests to those CDN providers (e.g., unpkg, cdnjs). Those requests are governed by the respective providers' privacy policies.
NitroIDE is provided as an open-source educational and development utility. By using the platform, you agree to utilize it responsibly. The sandbox environment is designed for frontend web development (HTML, CSS, JavaScript).
NitroIDE is built on the shoulders of giants. We utilize the following open-source projects to deliver a premium experience without requiring a backend:
