Psylo, which bills itself as a new kind of private web browser, debuted last Tuesday in Apple’s App Store, one day ahead of a report warning about the widespread use of browser fingerprinting for ad tracking and targeting.

It was a fortuitous coincidence.

Psylo for iOS and iPadOS was created by Mysk, a Canada-based app biz run by software developers and security researchers Talal Haj Bakry and Tommy Mysk.

“Psylo stands out as it is the only WebKit-based iOS browser that truly isolates tabs,” Tommy Mysk told The Register. "It’s not only about separate storage and cookies. Psylo goes beyond that.

“This is why we call tabs ‘silos.’ It applies unique anti-fingerprinting measures per silo, such as canvas randomization. This way two Psylo tabs opening the same website would appear as though they originated on two different devices to the opened website.”
