Overview
Worst Case Rating is a browser extension that reads the Google Maps page currently open in your tab, detects review-removal notices, and displays an adjusted worst-case star rating directly on the page. It does this entirely inside your browser.
The extension does not collect or transmit any personal data to the developer or to any third party. The only data it stores is kept on your own device, and the only network requests it makes go to Google Maps itself (see below).
What the extension reads
To compute the adjusted rating, the extension reads the visible text and
aria-label attributes of the Google Maps page that is already open in your
browser tab. Specifically, it looks for:
- The venue's current star rating
- The total number of visible reviews
- Any deletion-notice text (e.g. "X reviews removed due to defamation")
This data is used solely for the in-page calculation and is never sent to the developer or to any third party. To avoid re-fetching the same information when you re-open a venue, the extension caches it on your own device:
- Your chosen "average deleted stars" setting, in the browser's extension storage.
- Per-venue rating and deletion-notice data, in the tab's
sessionStorage(cleared automatically when the browser session ends). - A Google Maps request template, in
localStorage, so venue data can be looked up on later visits.
All of this stays on your device. None of it is transmitted to the developer or sold or shared with anyone.
Permissions
The extension declares content-script host permissions for Google Maps domains
(google.com/maps, google.de/maps, and equivalent regional
domains). This permission is the minimum required to inject the overlay card into
the Maps page.
It also uses the storage permission to save your settings and to cache
venue data on your device, as described above.
No other browser permissions are requested. The extension has no access to your browsing history, passwords, or any other personal information.
Network requests
To show the adjusted rating for venues in a Google Maps results list, the extension requests the relevant place data directly from Google Maps' own endpoints, reusing the Google session already active in your browser. These requests go only to Google — the same service whose page you are already viewing.
The extension operates no servers of its own. No request is ever made to the developer, and no data is sent to any third party.
Remote code
The extension does not load, execute, or evaluate any code from external servers. All logic is bundled in the extension package itself. The background script only opens the extension's about page in a new tab when the extension is first installed or updated.
Third parties
No analytics, tracking, or advertising services are used. No data is sold or transferred to any third party under any circumstances.
Children's privacy
This extension does not collect any information from anyone, including children under the age of 13.
Changes to this policy
If the extension is updated in a way that changes its data practices, this page will be updated before the new version is published to the Chrome Web Store.
