Tool inputs
The included browser tools process inputs in the page using JavaScript and standard browser APIs. The static implementation does not send tool inputs to an application backend.
Local preferences
The site may store a theme preference in localStorage. This stays in the browser until it is cleared by the user or browser.
External links
Links to external websites are governed by those websites' own privacy practices.
Operational logs
A web server may maintain standard access and error logs as part of normal hosting operations. Those logs are separate from the local tool inputs described above.
