Detect Price Discrimination Online

Overview

$heriff is an experimental desktop application designed to investigate potential price discrimination on the internet. The software enables users to examine whether e-retailers adjust prices based on user-specific data such as geographic location, browser type, operating system, referral source, or browsing history. By collecting and comparing product prices from multiple users within the same country, $heriff aims to reveal patterns of dynamic pricing that may not be visible to individual users.

The tool is primarily intended for privacy-conscious individuals and researchers interested in digital market transparency. It supports Windows, Mac, and Linux platforms, making it accessible to a broad user base. While the software does not collect personal data, users can opt into sharing cookies from specific websites and third-party domains when the donation feature is enabled. This data is used solely to support the research objective of identifying pricing disparities.

Real-world usage scenarios include comparing prices for the same product across different regions or devices, helping users determine if they are being charged more due to inferred user profiles. The software operates as a utility for informed online shopping and contributes to broader discussions about fair pricing practices in digital commerce.

Key Features & Capabilities

• Dynamic Price Comparison – Compares product prices across users in the same country using webRTC to securely exchange pricing data.
• Privacy-First Design – Does not collect session cookies or personal information by default; only cookies from selected websites are shared when donation is enabled.
• Browser Data Donation – Users can opt-in to share cookies and browsing history from specific domains to improve data accuracy and research insights.
• Experimental Research Focus – Designed to study behavioral pricing trends in e-commerce, helping identify potential algorithmic price discrimination.
• Cross-Platform Support – Available for Windows, Mac, and Linux, ensuring accessibility across major operating systems.

These features allow users to actively participate in a decentralized effort to monitor pricing fairness. For example, a user in Berlin can compare their price for a laptop with others in Germany, potentially revealing whether certain users consistently pay more. The tool is particularly useful for consumers who suspect they are being charged differently based on their digital footprint. It also supports academic and civic research into digital market transparency.
