Privacy should be understandable before you use a tool.

ToolHub is designed without a login system in this release. Many tools process your input locally in the browser.

Local processing

Tools marked In browser are designed to process your input in the current tab rather than upload it to a ToolHub application server.

Third-party libraries

A few advanced features download version-pinned browser libraries only when they are needed. The tool page explains that network requirement before processing.

Camera and microphone permissions

Device tests request camera or microphone permission only after you choose to start the test.
