1. When you buy something on Pinterest, you’ll need to share some payment and contact info with us so that we can complete your order. We’ll save this info so you don’t have to type it in next time you make a purchase. We’ll also share this info with the seller, and they’ll treat it as if you bought from their website directly.
2. We also hope to make Promoted Pins even more relevant and useful to Pinners like you. For example, if you purchased a camping tent on Pinterest, we may show you Promoted Pins for other outdoorsy products.
If you don’t want your purchases to be used to customize Pinterest, just go to “Order history” from your account settings and swipe to hide your purchases.
