See the price they show YOU vs the price they show an anonymous shopper. Catch personalized pricing in the act. Retailers show different people different prices. Price Parity catches them doing it. Online stores use your cookies, account history, and shopping behavior to decide what YOU should pay. It's called personalized (or "surveillance") pricing — and it usually costs the people who can least afford it. Price Parity fights back, right at the moment you shop: ⚖️ Price A/B Check — One click compares the price you're being shown against the price served to a cookie-less anonymous shopper. Same product, same second, side by side. If you're being charged more, you'll know — with advice on how to dodge it (incognito, clear cookies, log out). 🛡️ Tracking-Signal Shield — Blocks 36 data-broker and ad-tech identity networks, strips tracking parameters (utm, gclid, fbclid…) from links you click, removes third-party Referer headers, and sends the legally binding Global Privacy Control (GPC) opt-out signal. 📈 Price Hike Alerts — Remembers prices of products you've viewed (stored ONLY on your device). Come back to a product that quietly went up? A banner calls it out. Price dropped? You'll know it's a good time to buy. Privacy is the whole point: • No account. No sign-up. • Zero data collection — we never receive your data, so we couldn't sell it if we wanted to. • All price history stays in your browser's local storage. • Open source. Honest about limits: Price Parity detects cookie/account-based price personalization — the most common kind. Pricing based on your IP location can't be detected without a proxy (on the roadmap). Some sites block anonymous requests; we tell you when that happens instead of guessing. Built by one developer who believes people who make less money deserve a fair price at every turn.
