Privacy Policy — GSC Compare % Change

Last updated: August 16, 2026

GSC Compare % Change is a browser extension that adds percentage-change badges to Google Search Console's Performance report when you're comparing two time periods, and helps align year-over-year comparisons so both periods land on the same day of the week.

Data collection

This extension does not collect, store, transmit, or share any data, personal or otherwise. It does not use analytics, does not make any network requests, and does not communicate with any server.

How it works

The extension runs a small script only on pages under search.google.com/search-console/performance. That script reads text already visible on the page — metric values, dates, and labels — to compute and display percentage-change badges. For the date-alignment features, it also reads and writes values into the date fields of Search Console's own "Compare" date-range picker on that same page. This all happens entirely within your browser — nothing is sent anywhere, and nothing is saved between sessions, including by the extension itself.

Permissions

The extension requests access only to https://search.google.com/search-console/performance*. This is required so the content script can read the page and display badges, and adjust the comparison date fields when you use the alignment features. No other host or browser permissions are requested — the extension does not use storage, tabs, scripting, or any other Chrome extension API.

Third parties

This extension is not affiliated with, endorsed by, or sponsored by Google. It is an independent tool that adds visual badges and date-alignment convenience while you use Google Search Console.
