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 uses Google Analytics 4 to measure aggregate page views. Google Analytics sets its own first-party cookies in your browser — names beginning with _ga — which it uses to tell repeat visits apart from new ones.

RankingDiff still has no login and no account system of any kind.

This site self-hosts its typefaces and does not load fonts from Google Fonts or any other external font service.

Google Analytics 4, provided by Google, is the one third-party service RankingDiff uses. Its script is loaded from googletagmanager.com.

What Google Analytics receives is the standard analytics information for a page view: the URL of the page you are viewing, the referring URL, an approximate location derived from your IP address, information about your device and browser, and the fact that the page was viewed.

Google Analytics is separate from the analysis engine described above. The CSV files you upload, their filenames and contents, the queries and pages inside them, and any other Search Console data are not sent to Google Analytics. That analysis stays in your browser.

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.
