Pasted text and cleaned output
The input, cleaning rules, detection report, and output run in JavaScript on your device. The application does not send pasted text to an AI service or a cleaning API. Input and output are held in the page's memory, rather than saved by the application to local storage or a database.
Clear removes the text from the current tool view and briefly keeps an undo copy in page memory. This is not a guarantee of secure erasure from device memory or browser history features. Your browser, extensions, operating system, and clipboard manager may have their own handling of content you enter.
Preferences, downloads, and clipboard
Selecting a preset saves its name in browser local storage under cpt-preset. This allows later visits to use that preference. You can remove it by clearing this site's browser data. No document content is stored in that preference.
Copy writes the result to your system clipboard when you click it. Download creates a text file locally and asks your browser to save it. Copies and downloaded files remain under your device's normal storage and clipboard controls.
Site analytics and network requests
The site includes Google Analytics. Analytics requests can carry page and browser information and may use cookies according to the service's configuration and your browser settings. Cleaner events record actions such as copy, paste, and example selection. They can include a preset name, example identifier, or a broad text-length bucket, such as 1k–10k characters. They do not include the pasted text or output.
Loading the site also requests HTML, scripts, styles, and icons from its hosting service. Local text processing does not mean that visiting the website makes no network requests. Review the source code for the implementation and report a concern or correction through the project repository.
