Pinterest SampleIf you visit Pinterest today, you’ll find a notification banner at the top of the page.

“Hey there! On October 19, 2014, we’ll update our privacy policy to help make Promoted Pins more relevant. Here’s what’s new.

The link takes you to the updated policy and if you scroll up you’ll see the original policy but Pinterest doesn’t call out what’s different from one to the other. That’s not nice.

I compared the two docs and here’s what I found.

The first section of the privacy document is called “What information do we collect?”. Right now, all information is lumped together under two headings. In the new document, Pinterest gives partners and advertisers their own section.

3. Our partners and advertisers may share information with us

Sometimes our partners may let us collect information when you use their services, or may share with us the information they collect. For example:


— Some websites or apps use Pinterest features like our “Pin it” button. If so, we may collect log information (described above) from those sites or apps.

— Online advertisers typically share information with the websites or apps where they run ads to measure and/or improve those ads. We also receive this information, which may include information like whether clicks on ads led to purchases or a list of criteria to use in targeting ads. To learn more about the types of information advertisers may share with us, please see our Help Center.

Another change appears in the “How we share” data section.


Online advertisers typically use third party companies to audit the delivery and performance of their ads on websites and apps. We also allow these companies to collect this information on Pinterest. To learn more, please see our Help Center.


Neither of these are huge changes but it’s interesting that Pinterest is calling them out in a bigger way. Maybe because they’re getting ready to do an even bigger push into audience tracking land.

AdAge notes a few more changes in the Pinterest Help Center:

An advertiser may add a pixel to their website to help us understand who’s bought something on their site. This pixel lets us measure purchases that come from Pinners viewing or clicking on the advertiser’s Promoted Pins. We may use that data to report to the advertiser how effective their Promoted Pins are. We may also use that data to customize your Pinterest experience. If you don’t want us to use this info to personalize the Promoted Pins you see, go to your account settings and turn off Personalization.

An advertiser may share a “hash” (basically an anonymized scramble) of some identifiers (for example, email addresses). We can then match that with Pinterest users, and use the match to show targeted Promoted Pins to that group of people. If you don’t want us to target Promoted Pins to you this way, go to your account settings and turn off Personalization.

We may allow an advertiser, or company working for an advertiser, to place a pixel or similar technology on its Promoted Pins. This pixel lets the advertiser collect info on how well the Promoted Pin is doing.

A spokesman told AdAge that Pinterest doesn’t currently have a conversion tracking or audience targeting program but once everyone signs off on the new privacy policy.  . . well. . let’s just say they didn’t take the time to write all of those new documents for nothing.

Pinterest may be the baby of the social media family, but she’s learned her lessons well from her older “more experienced” siblings.
