We do not sell your personal information, and we never have. We do share one thing for advertising, in the specific sense California law gives that word: when you place an order, a scrambled (hashed) form of your email address is sent to Pinterest so it can tell whether one of our adverts led to the sale. Pinterest can match that against an account it already has; it cannot read your address from it.
We send no name, no delivery address and no payment details to any advertising network.
Your browser can ask for this automatically. If it sends a Global Privacy Control signal — some browsers do by default, and extensions add it — we treat that as an opt-out on every page, without you having to come here. You do not need to do anything else.
Your choice is remembered in this browser, so it will need making again on another device or after clearing your site data. The privacy policy sets out everything we hold and how to have it deleted.
