A new privacy-focused web browser called Psylo has launched on Apple’s App Store, promising enhanced protection against advanced tracking techniques such as browser fingerprinting. Developed by Canadian app company Mysk, Psylo offers full tab isolation on iOS and iPadOS, creating completely separate environments for each browsing session to prevent cross-site tracking.
Psylo arrives at a time when traditional privacy safeguards are under strain. Google’s most recent delay of its third-party cookie phase-out, announced in mid-2024, reflects the challenge of balancing privacy with web compatibility.
The browser’s main innovation is its tab siloing system, which applies distinct anti-fingerprinting protections to each tab. “Psylo stands out as it is the only WebKit-based iOS browser that truly isolates tabs,” said co-developer Tommy Mysk in an interview with The Register. “Two Psylo tabs opening the same website would appear as though they originated on two different devices to the opened website.”
Each tab can route traffic through a different IP address using Mysk’s Private Proxy Network, which supports more than 40 proxy locations. Additional techniques such as per-tab canvas randomization help block websites from creating unique digital fingerprints based on device traits.
After releasing its first beta in February 2025, Mysk applied for and in March received Apple’s “Default Browser Entitlement,” enabling users to set Psylo as their system browser and allowing integration with iOS features like password managers and passkeys.
Psylo is currently available on iOS and iPadOS. It offers a free seven-day trial followed by a subscription plan, with no account registration required. According to its privacy policy, the app does not collect identifying metadata and tracks only the user’s subscription status.
The developers say they may consider expanding to Android if the iOS version performs well. As privacy concerns surrounding digital tracking and fingerprinting grow, Psylo’s isolation-based approach marks a notable development in the browser space.
