What They Say
Pinterest describes itself as a platform for inspiration and ideas. Their policy explains they use pin and search data to show you more relevant content, and that they serve ads based on your interests. They have a relatively accessible privacy explanation and allow users to download their data.
What They Mean
Pinterest is the most intimate advertising product the Bureau has reviewed. Users explicitly declare their life intentions — wedding planning, pregnancy preparation, home renovation, diet changes, mental health approaches, parenting philosophies — by creating boards and saving pins. This declared intent is extraordinarily valuable to advertisers because it bypasses inference. Pinterest doesn't need to guess that you're planning a wedding: you named a board 'my wedding.' This explicit life-stage data is sold to advertisers with a precision that behavioural inference cannot match. Pinterest's revenue model is built on the fact that its users willingly document their deepest aspirations in searchable, categorisable visual form.
Worst Clause — Exhibit A
"We use your information to serve you better, more relevant ads on Pinterest. We also use it to measure whether ads are working and to show you ads about things we think you might like based on what you save, search, click on and your age and location."
Bureau Translation:
'Things we think you might like based on what you save' is the business description of advertising informed by declared life intentions. Your wedding board, your baby names board, your grief and loss board, and your weight loss board are all advertising categories. The Bureau notes that users who save pins about mental health, pregnancy, or financial difficulty are receiving targeted advertising based on moments of personal vulnerability. This is disclosed but the implications are not featured prominently.

Bureau Verdict
"Pinterest's business model is selling access to people's declared hopes and dreams to advertisers. The platform is designed specifically to encourage users to document their aspirations in explicit, searchable categories, and then monetises this documentation at scale. Grade D-: the data collection matches other social platforms but the declared-intent nature of Pinterest's content makes the privacy implications significantly more intimate."
