[ PRIVACY ]
CodeLab collects nothing itself.
No backend, no accounts, no analytics
CodeLab is a static website: it runs no server code, stores no user data, requires no account, and ships no analytics or advertising trackers of its own. There is nowhere on CodeLab's own infrastructure for your code or identity to be saved — because that infrastructure does not exist.
Your code runs in the embedded runtime
When you press Run, your code executes inside the embedded OneCompiler editor, a third-party service loaded in an iframe. Whatever you type, paste or run is subject to OneCompiler's own privacy policy and terms — review them at onecompiler.com before running sensitive code.
Hosting
The site is hosted on Vercel, which processes standard web logs (such as IP addresses and request metadata) to deliver pages. See Vercel's privacy policy for details.
Shared links
Playground share links encode run state in the URL itself. Anyone with the link can open that state — so never put secrets, passwords or personal data into shared code.
