Privacy Policy

RentScope collects no personal data and sends nothing to any server. All processing happens entirely within your browser. There are no analytics, no tracking pixels, no third-party SDKs, and no network requests to any external service from this extension.

RentScope reads the DOM of Zillow and Apartments.com listing pages to extract rental information (price, bedroom count, ZIP code). This data is used locally to look up HUD FMR data and display the overlay. It is never transmitted off your device.

RentScope stores the current listing data in chrome.storage.local so the popup can display it. Data is keyed per site (rent_zillow / rent_apartments) and overwritten on each new listing. No data is stored in chrome.storage.sync or sent to any cloud service.

The FMR data is bundled inside the extension package (fmr_index.json, ~2–3 MB). It is read locally — no network request is made to HUD or any other server at runtime.

Used for chrome.storage.local to pass the current listing data between the content script and the popup. Data is site-scoped and overwritten on each navigation. No personal data is ever stored.

Used to detect whether the active tab is a Zillow or Apartments.com listing page, so the popup can show the correct data for the current site. The extension does not read tab URLs beyond checking the hostname and path.

Required to inject the content script and track SPA navigation. Zillow is a single-page app — the extension must be present on search pages to detect when you navigate into a listing. No data is read or collected on non-listing pages.
