Your content stays in your browser

Text and image processing

Pasted text is held in the page's form controls and JavaScript memory. Selected image files are read with browser file APIs. Checks, removals, output generation, preview, copy, and download happen on your device.

The application does not use fetch, XMLHttpRequest, WebSocket, beacon requests, cloud AI models, or remote parsing services. A restrictive Content Security Policy also sets connect-src 'none' and form-action 'none'.

Normal website requests still occur

Loading this site requests static HTML, CSS, JavaScript, and image files from Cloudflare. Cloudflare therefore receives ordinary request information such as an IP address, timestamp, requested path, browser details, and security signals. Your pasted text and chosen image file are not part of those requests.

Cloudflare's handling of infrastructure data is governed by its privacy policy. Watermark Tidy does not add Cloudflare Web Analytics, client-side monitoring, or an analytics beacon.

No application cookies or persistent storage

• No account or login identifiers
• No application cookies
• No localStorage, IndexedDB, or service worker
• No saved text, images, or result history
• No marketing or behavior analytics

Temporary object URLs used for image previews and downloads are revoked when you reset the tool, select another file, or leave the page.

Browser text services are disabled

The text field disables spellcheck, autocorrect, autocomplete, and form serialization. This reduces the chance that enhanced browser writing services receive pasted text. Browser extensions and operating-system tools remain outside the website's control, so use a clean browser profile for unusually sensitive content.

Cleaned downloads

Cleaned text and images are generated locally. A download saves the generated copy through your browser. The original input remains unchanged unless you separately replace it yourself.
