How we handle data

Plain English, five parts.

What we collect, what we never store or show, where our market numbers come from and how old they can be, what a card is, and how to get your data deleted.

01What we collect

02What we never store or show

03Where comps and market data come from, and how old they can be

Market context (metro and zip medians, homes sold, days on market) comes from Redfin's free public data, published monthly. Redfin publishes with a lag, so these figures are usually a few months behind.

Sold and rental comps come from RentCast. A sold comp only counts toward a score if it sold within the last 90 days. When there are not enough recent sales in a zip, the score falls back to market context, or to the listing alone, and the card says which.

04A card is HouseRadar's read, never a copy of an ad

A card shows the ad's title, asking price and a photo, and links back to the original post. Everything else on it is ours: the score, the line saying what the score stands on, any cap, and the written read.

A model does the reading. Its score is capped by evidence it cannot invent: a missing address, no photos, no recent sales nearby, or a price that doesn't fit the market all hold a score down no matter how good the ad sounds. Every card shows what it had to go on, and when a cap held it down, the card says so.

05How to get your data deleted
