# Privacy Policy for Proptima Chrome Extension

**Last Updated:** January 2025

## Overview

Proptima is a Chrome browser extension designed to help property buyers and investors organize and track properties from Zillow search results. This privacy policy explains how the extension processes and stores information locally on your device.

**We do not collect user data.** All information is processed and stored locally on your computer for your personal use only.

**Important Disclaimer:** This extension is not affiliated with or endorsed by Zillow and is independently developed solely to help users organize and track properties for their personal use.

## Information Processing and Local Storage

**Important: We do not collect or transmit any user data. All information is processed and stored locally on your computer.**

### 1. Property Data Processing

When you use Proptima on Zillow.com, the extension processes publicly available property information displayed on the webpage and stores it locally in your browser:

The extension stores the following information locally on your device when you voluntarily provide it:

- Personal comments about properties

- Property status flags (Interested, Not Interested, etc.)

- Timestamps of when you last updated property information

### 3. Technical Processing

The extension processes minimal technical information necessary for functionality, but does not collect or store personal data:

- Reads current active tab URL (only when on Zillow.com) to determine functionality
