PriceWatch

See when a store shows you a higher price than other shoppers get, and why. Works on product pages across shopping sites.

Are you being shown a higher price than other shoppers? Stores can change prices based on who they think you are: whether you're logged in, what device you're on, how you arrived at the page. You never see what anyone else is offered, so you never know. PriceWatch checks for you. When you open a product page on a shopping site, it quietly loads the same page a few more times as "strangers": clean copies with no cookies, no login and no history, one looking like a computer, one like a phone, and one arriving from a Google search. If you're shown meaningfully more than a stranger, PriceWatch warns you right on the page, tells you what likely caused it, and how to avoid it. • Works on product pages across shopping sites, not just a few big stores. • The strangers never touch your account, your cookies or your cart. They never click, add to cart, log in or buy. • Warns only when the difference is real: more than 5% and more than $5. When in doubt, it stays quiet. • Each product is checked at most once every 6 hours. • Honest about what it could check: it tells you how many of the strangers it compared, and when a store blocked one. YOUR DATA, YOUR CHOICE PriceWatch does nothing until you choose how much to share: • Full sharing: the prices you and the strangers saw, whether you appeared logged in, a rough region and device type, and a random ID for this install so you can wipe everything. • Local only: just the price you were shown, with rough region and device type, anonymously. PriceWatch never collects your name, email, address, payment details or passwords, nothing from non-shopping websites, and nothing from sensitive stores such as pharmacies, health or adult sites. It never sells your data or uses it for ads. One button in Settings permanently deletes everything PriceWatch has stored about you, on your computer and on our server, immediately. WHY SHARE? The more prices PriceWatch can compare, the better it can explain what raises prices, and the harder it becomes for stores to charge people more just for being who they are.
