WHAT THE POLICIES SAY

Pinterest is an advertising-funded visual discovery platform whose privacy policy describes collecting device information including unique device identifiers, inferring approximate location from IP address even when the user has not chosen to share precise location, and using on-platform activity to build inferences about preferences. The policy states Pinterest discloses identifiers such as cookie IDs, IP addresses and hashed email addresses to third parties it names, including Facebook Ads and Google Marketing Platform, and shows ads both on and off Pinterest. In October 2024 the privacy organisation noyb filed a complaint with France's CNIL alleging Pinterest tracks European users for personalised advertising on a legitimate-interest basis without consent and failed to answer a data-access request completely; Pinterest states its approach is GDPR compliant, and the complaint was undecided as of this drafting.

These are allegations in a pending complaint, not findings, as of this drafting.
