Privacy Policy & Architecture

Browser Tools is built on a zero-upload architecture. When you paste text, decode a JWT, compress an image, or convert JSON, all processing occurs locally in your browser's JavaScript engine and HTML5 Canvas APIs.

Data handling guarantees

• No server transmission: Your inputs, payloads, and files are never sent over the network to any server.
• No tracking or user accounts: We do not use third-party analytics pixels, user profiling, or cookies for user tracking.
• Local storage: The site only saves your theme preference (Light/Dark/System) and your list of favorited tool IDs in your browser's localStorage. No payload data is ever persisted.
• Local data erasure: You can clear your stored preferences anytime by clicking “Reset local data” in the sidebar or clearing your browser site data.

Verification

You can verify these claims at any moment by opening your browser's Developer Tools (F12 or Ctrl+Shift+I / ⌘+Option+I), inspecting the Network tab, and using any utility. No HTTP POST or PUT requests are dispatched when processing your data.
