Clear answers before you enable it.

What does PriceGlass share?

Product details, displayed price, identifiers, variant, availability, observation time and a canonical product path. It does not assign a persistent shopper ID. Product paths and times still reveal supported product pages visited; hosting providers process IP addresses and network metadata. See the privacy policy for the full explanation.

Does it search other websites for me?

No. Comparisons come from shared observations of matching products. If no recent cheaper matching offers have been contributed, the extension says so.

Does it guarantee the lowest price?

No. Observations may be sparse or inaccurate, and shipping, tax, seller, location, coupons and membership can change checkout prices. Confirm the offer with the retailer.

Can I stop contributing?

Yes. Turn PriceGlass off or uninstall it. Contributions cannot be switched off separately while using the enabled price feature.
