Privacy Policy

RankingDiff does not have a server-side backend for the analysis. The CSV files you upload on the Analyze page are read and processed entirely inside your browser, using JavaScript running on your own device. They are never transmitted anywhere, never stored in a database, and never seen by anyone but you.

Your analysis result is held briefly in your browser's sessionStorage so it can be handed from the Analyze page to the Results page. sessionStorage is local to your browser tab and is automatically cleared when you close it — it is never sent over the network.

Your light/dark theme preference is stored in your browser's localStorage so the site remembers your choice on future visits to this device. This is the only value RankingDiff writes to localStorage.

RankingDiff does not use cookies, does not run any analytics or tracking scripts, and does not have a login or account system of any kind.

This site loads its typefaces from Google Fonts. Loading a font file involves a request to Google's font-serving domains; no page content or uploaded data is included in that request. No other third-party service is contacted by this site.

If RankingDiff's data handling ever changes — for example, if a server-side feature is added in the future — this page will be updated to describe it accurately before that change ships.
