Visiting Subway’s website on a personal computer might not seem to have anything to do with checking the NFL’s app on a phone. But these discrete activities are the foundation for a new service to help marketers follow you around.

Adobe, a company better known for Photoshop and PDF files, says the new initiative announced Wednesday will help companies offer more personalized experiences and make ads less annoying by filtering out products and services you have already bought or will never buy.

But it comes amid heightened privacy sensitivities after reports that Facebook allowed a political consulting firm to harvest data on millions of Facebook users to influence elections.

And Adobe’s initiative underscores the role data plays in helping companies make money. Many of the initial uses are for better ad targeting.

Adobe says no personal data is being exchanged among the 60 or so companies that have joined its Device Co-op initiative already. These include such well-known brands as Allstate, Lenovo, Intel, Barnes & Noble, Subaru, Subway, Sprint, the NFL and the Food Network. Adobe says the program links about 300 million consumers across nearly 2 billion devices in the U.S. and Canada.

Under the initiative, Adobe can tell you’re the same person on a home PC, a work laptop, a phone and a tablet by analyzing past sign-ins with member companies. With that knowledge, Sprint would know Bob is already a customer when he visits from a new device. Bob wouldn’t get a promotion to switch from another carrier, but might get instead a phone upgrade offer. Or if Mary has declared herself a Giants fan on the NFL’s app, she might see ads with Giants banners when visiting NFL.com from a laptop for the first time.

All this might feel creepy, but such cross-device tracking is already commonly done by matching attributes such as devices that from the same internet location, or IP address. Consumers typically have little control over it.

Adobe says it will give consumers a chance to opt out of such tracking. And it’s breaking industry practices in a few ways. Adobe says it will honor opt-out requests for all participating companies and for all devices at once. It’s more typical for such setups to require people do so one by one. All companies in the initiative are listed on Adobe’s website, a break from some companies’ practice of referring only to unspecified partners.

“We’re doing everything we can not letting brands hide themselves,” Adobe executive Amit Ahuja said.

But in taking an opt-out approach, which is common in the industry, Adobe assumes that users consent. And it places the burden on consumers to learn about this initiative and to figure out how they can opt out of it.
