Privacy model

Your text stays on your device.

PasteTidy is a static website. Its tools run in your browser and do not send pasted text or opened files to a server.

What happens when you use a tool

Your browser downloads the site’s HTML, CSS, and JavaScript. When you paste text, choose a local file, or process a result, that work happens inside the current browser tab. Large jobs may run in a Web Worker, which is still local to your device.

Data PasteTidy does not collect

  • Input and output text
  • Contents of files opened with the File API
  • Clipboard contents beyond the result you explicitly copy
  • Accounts, profile information, or authentication credentials
  • Analytics events, tracking identifiers, or advertising profiles

Harmless settings stored locally

PasteTidy can store a color-theme preference, a list of recently opened tools, Text Cleaner pipeline settings, and optional short Find and Replace patterns. These values remain in browser local storage and are not synchronized. Input and output text are never saved there.

Files and downloads

Opening a text file uses the browser File API. Downloading a result creates a temporary Blob URL on your device. Neither action uploads the file to PasteTidy.

Cookies and third parties

The initial release does not use analytics, advertising, tracking cookies, third-party fonts, or scripts that can inspect tool inputs. Hosting infrastructure may receive ordinary request metadata when it serves static assets, but tool content is not part of those requests.

Clear local preferences

You can remove PasteTidy’s local preferences through your browser’s site-data settings. Clearing site data deletes saved themes, recent-tool shortcuts, local presets, and optional replacement history.
