About this extension

FunData shows you how a neighbourhood measures up according to CheckJePlek.nl right on a Funda
listing page

Automatically fetches neighbourhood data when you activate the extension on a
property detail page on Funda (for sale and for rent)
Displays RIVM scores for things like noise, air quality and hazardous
substances, using the same smiley icons as the official "Check je
Plek" tool
Interactive map (Leaflet) centred on the address, with an optional
cadastral boundary overlay (PDOK/Kadaster)
Light/dark theme, auto-detected from your browser or system
preference, with a manual override switch
Configurable: icon or text-label scores, static or dynamic map

Architecture and privacy

Works entirely through direct calls to open Dutch government APIs
(PDOK for geocoding, RIVM/Sogelink for neighbourhood data) — no
scraping and no hidden iframe of Funda or any third party
The address of the page you're viewing is sent to these Dutch
government APIs to perform the lookup; that's the only data
transmission the extension does
No tracking, no analytics, no telemetry
Nothing is stored beyond your own settings, kept locally in the
browser
