Your working text stays in the tab.
The core release has no analysis backend, accounts or telemetry endpoint. Tool inputs are processed by browser JavaScript.
What is processed
Text entered into the utilities is processed in the browser. The production core does not contain an endpoint that receives tool input or generated results.
Local browser state
The light/dark preference is stored in localStorage. Tool inputs are not persisted by the application. Files selected by file-based utilities are read by browser JavaScript for the current tab.
Advertising
Advertising code is not enabled in this release. The layout reserves isolated ad zones, but the active Content Security Policy blocks third-party ad requests. Before enabling an ad network, this policy, the privacy notice and any required consent flow must be updated.
Limits
Browser-only processing prevents this application from uploading tool content, but extensions, the browser itself, the operating system and third-party software remain outside this application's control.
