This policy explains what the PropertyPredator browser extension (the "Extension") does with data. It is deliberately short because the Extension is built to collect as little as possible.
On supported Rightmove, Zoopla and OnTheMarket property-detail routes, the Extension activates automatically and reads the page in your browser to identify the property's location and basic attributes, and shows you our free market intelligence (sold-price comparables, area price context, planning/risk flags, registered owner and covenant information from public records).
Choosing Read this listing from the extension toolbar asks the Extension to read the current HTTP(S) page, including on other websites. Extraction may not work where readable property details are unavailable.
Only the minimal facts needed to run the analysis are sent to our server (propertypredator.com): the available property address and postcode, asking price, bedrooms, property type, floor area, listing site's hostname, detected days on market and description-derived signal labels. These are extracted facts and labels, not the raw listing description or photos.
We do not receive, store, or republish the listing's photos, description, agent details or any other page content. We are augmenting your own view of a page you chose to open — not copying the site.
If you sign in through the Extension to use paid features (e.g. a live valuation), your email and password are sent over HTTPS to our authentication service solely to log you in. We store access and refresh tokens locally in your browser's extension storage so you stay signed in. We never sell or share your credentials.
The Extension also stores your area-unit and Light/Dark/System appearance preferences locally in your browser's extension storage.
To produce the analysis we query public and licensed data services (including HM Land Registry open data and postcode lookup services). Only the property's location and attributes are sent to these lookups — never your identity.
Requests are processed to return your result and are not used to build a profile of you. Account data is retained for as long as you have a PropertyPredator account; delete your account to remove it.
