Privacy policy — Rightmove Companion

Effective date: May 2026

Summary

Rightmove Companion runs inside your browser. It stores your settings and saved data locally on your device. It reads property listing pages you open and may fetch public listing pages on other property sites to estimate rent comparables. It does not sell your data.

Data stored on your device

The extension uses chrome.storage.local to keep:

• default calculator inputs
• drafts for the listing page you are viewing
• saved properties and optional notes
• simple UI preferences (for example whether the panel was open)

This data stays on your computer unless you use export yourself (for example to save a JSON backup file).

Data the extension accesses

• Rightmove pages you visit that match the extension’s content script (for-sale property URLs). The extension reads the visible page to fill in price, address, and similar fields where the page exposes them.
• Zoopla and PrimeLocation (only as network requests from the extension’s background service worker) to gather public lettings search HTML used for rent comparable ranges. The extension does not read your accounts on those sites.

Optional developer builds

If you build the extension yourself with a local LLM proxy URL, that proxy is your server. The Chrome Web Store release build does not include localhost access or a baked-in proxy URL.

Contact

Questions about this policy: please use the contact option listed on the Rightmove Companion Chrome Web Store page or your publisher support email.

Changes

We will note material updates here when what the extension collects or sends changes.
