Frequently Asked Questions

Everything you need to know about the Postcodewise Property Report browser extension.

Is the browser extension free to use?
Yes. The extension is completely free for all Postcodewise users. Free personal accounts receive monthly complimentary report credits, while Pro and Business subscribers enjoy unlimited lookups.
Which property portals work with the extension?
The extension automatically detects listings on Rightmove (rightmove.co.uk), Zoopla (zoopla.co.uk), OnTheMarket (onthemarket.com), PrimeLocation (primelocation.com), and OpenRent (openrent.co.uk).
How does the extension work without slowing down my browser?
The extension uses a lightweight content script that only runs when navigating supported property portals. It inspects the page metadata in the background to detect the address and postcode, badging the icon without consuming CPU or memory on other tabs.
Does the extension track my browsing history or collect my data?
No. Postcodewise is built with a strict privacy-first model. The extension runs locally in your browser, only activates on property portal domains, stores your auth token in your private browser storage, and communicates solely with the official Postcodewise API. We never sell, track or share your browsing activity.
How do I connect my Postcodewise account?
Click the "Connect Account" button inside the extension side panel. It will open our secure connect page on postcodewise.co.uk, link your authenticated session with a single click, and immediately unlock full reports in your browser.
How do I update the extension after new releases?
If loaded unpacked in developer mode, download the updated ZIP, replace the folder contents, and click "Update" or "Reload" in your browser's extension manager. When installed from the Chrome Web Store, Edge Add-ons, or Firefox AMO, updates are applied automatically by your browser.
