DealView Privacy Policy

Last updated: April 2026

Overview

DealView is a Chrome extension that adds real estate investor analysis directly to Zillow listing pages. This policy explains how DealView handles your data.

Data We Do Not Collect

DealView does not collect, transmit, sell, or share any personal data. There are no accounts, no servers, and no databases associated with this extension. Your information never leaves your device.

Data Stored Locally

DealView stores the following data exclusively in your browser’s local storage using the Chrome Extension Storage API (chrome.storage.local):

Saved analyses — property addresses, list prices, and investor metrics you have chosen to save
User preferences — your input defaults (down payment %, expense ratio, etc.)
API response caches — market data from public APIs (HUD FMR, Census ACS, FRED mortgage rates), cached locally to reduce redundant network requests

This data is stored only on your device and is never transmitted to any third party.

External API Requests

DealView makes requests to the following public APIs to fetch market data. These requests do not include any personally identifiable information:

API	Purpose	Data Sent
HUD Fair Market Rent API	Fetch area-level fair market rents	State code, ZIP code
U.S. Census Bureau ACS API	Fetch median household income and gross rent by ZIP	ZIP code
FRED (Federal Reserve Bank of St. Louis)	Fetch current 30-year and 15-year mortgage rates	None (public series request)

Zillow

DealView reads publicly visible listing data directly from Zillow web pages you are already viewing. It does not scrape, store, or transmit Zillow data to any server.

Permissions

DealView requests the following Chrome permissions:

storage — to save your analyses and preferences locally
sidePanel — to display the analysis panel alongside Zillow listing pages
Host permission for zillow.com — to read listing data from pages you visit
