What stays in the browser
Pasted text, selected files, image previews, spreadsheet input, and folder comparison data are handled locally in the page so you can review differences without sending the compared content to this site for storage.
Privacy
Compared content stays local.
Text, file previews, spreadsheet input, and folder metadata are processed in the browser. This site does not store the compared content you provide.
What this site does not store
The compared content itself is not saved by compare-anything. When you leave the page, your text and uploaded file contents are not kept by this site.
Local preferences
The interface can remember lightweight preferences such as language choice or dark mode in your own browser so the site opens the way you prefer next time.
Ads and third-party services
Advertising services such as Google AdSense can use their own request data according to their policies. That is separate from the compared content you enter into the tool itself.
