A New Kind of Private Browser
Psylo isolates every tab into its own silo with separate storage, cookies, and its own IP address from our global proxy network. Advanced anti-tracking techniques stop trackers from connecting your sessions.

VPNs are not enough
You open a private tab and turn on a VPN. You browse a news site, close the tab, and visit a different site later. Ad networks can still link both visits to you, even without cookies or an account.
Trackers use "browser fingerprinting." They look at your timezone, screen resolution, operating system, and the unique way your device renders graphics (canvas hashing). When they combine these signals, they create a unique profile for your device. Because nothing is stored on your device, you can't delete it. It persists across incognito mode, browser restarts, and VPNs.
See It For Yourself
Your browser exposes your timezone and system language to every site you visit. Trackers use these signals to infer your country—or wherever you happen to be travelling. No special permissions required.
Try it: open this page in a private window with your VPN on. Your timezone and locale still give you away. Psylo spoofs both to match your proxy.
Every Tab Is a Silo
Imagine you're buying a gift in one tab, reading the news in another, and checking work email in a third. Normally, trackers embedded across these sites share your data to build a single profile of you.
In Psylo, every tab is a silo. Each silo gets a distinct IP address, isolated cookies, and a unique browser fingerprint. Trackers on different tabs see completely different users connecting from different countries. There is no shared identity.
Isolated Storage
Signing into a site in one silo does not sign you in anywhere else. Cookies, cache, and local storage remain locked within that silo.
Per-Silo Proxy
Each silo connects through a different proxy server. You can route one tab through Canada and another through Japan simultaneously.
Private by Default
There is no VPN toggle or incognito mode to enable. Psylo isolates every session automatically.
Block Tracking at the Source
Hiding your IP address is only the first step. Psylo also spoofs your timezone, locale, and user agent to match your proxy's exact location. Trackers see a consistent profile from that region—not yours.
40+ Servers. Zero Logs.
We wrote and maintain the software running our proxy servers. We keep no logs and create no user accounts. The only check our system performs is verifying whether your Apple subscription is active using an anonymous identifier.
Ditch Native Apps
Native apps embed third-party tracking SDKs that log your activity. Accessing the web versions of platforms like X, Instagram, YouTube, LinkedIn, and Amazon keeps their tracking sandboxed. Run each one in an isolated silo with its own IP address, and sign into multiple accounts side by side.
Clean Browsing
No extensions needed. Psylo handles ads, cookie banners, and tracking parameters natively.
Ad Blocker
Blocks ads, pop-ups, and auto-play videos across every tab and silo.
Cookie Banner Blocker
Dismisses cookie consent banners and "accept all" dialogs automatically.
URL Tracker Cleaner
Strips utm_source, fbclid, gclid, and other tracking parameters from every link.
More Built In
Content Filtering
Integrated ad blocking, cookie banner blocking, and URL parameter cleaning.
Zero Analytics
Psylo collects no analytics data. We improve the app from direct user feedback, not usage statistics.
No Account Required
Pay through App Store subscriptions. We never ask for your personal information.
No Profiles Installed
Psylo doesn’t install any configuration profiles on your device. Unlike VPNs, everything stays inside the app.
Ephemeral Silos
Enable auto-purge to automatically delete all session data when you close the tab.
Custom Proxies
Add your own SOCKS5 or HTTP/HTTPS proxies to use alongside the built-in Mysk network, or use proxy servers from third-party providers like Mullvad and IVPN.
Custom Search Engines
Select Brave, DuckDuckGo, Google, or Ecosia, or add custom engines like Kagi.
Multi-Line Address Bar
Psylo’s address bar spans multiple lines, making long search queries and AI prompts easy to type and edit.
TLS Certificate Viewer
Inspect the technical details of the TLS certificates for the websites you visit.
Built by Privacy Researchers
Since 2020, the two of us behind Mysk have researched how apps track and fingerprint users. We never set out to build a browser; we just wanted a way to escape the tracking SDKs in native apps. But nine months later, we had built everything we knew about tracking into a single browser.
Psylo is the tool we built for ourselves to stop cross-site tracking.

What is a silo?
A silo is an isolated browsing environment. Each one maintains its own cookies, cache, local storage, and IP address. Because nothing is shared between silos, cross-site tracking has no path between them.
How is Psylo different from a VPN?
VPNs assign one IP to your entire device—every app and browser shares it. Psylo gives each silo a separate IP and goes further: it spoofs your timezone, locale, and user agent to match the proxy’s location, and randomizes your canvas fingerprint each session. A VPN cannot prevent browser fingerprinting.
How can I use Psylo with Progressive Web Apps?
Open the same PWA—X, Instagram, TikTok—in multiple silos to log into different accounts at the same time. Each silo keeps its own cookies and browsing data, so the service cannot link the accounts. Unlike native apps, PWAs give tracking SDKs no access to your device.
How many silos can I create?
There’s no limit. Each silo connects through one of the 40+ servers on the Mysk Private Proxy Network, giving it a distinct IP address.
Does Psylo log my browsing data?
No. We log neither IP addresses nor visited websites. Bandwidth usage is tracked with randomized identifiers solely to prevent abuse.
Do I need to create an account?
No. Psylo uses Apple’s App Store subscriptions. We never collect personally identifiable information, and there are no user accounts. Our backend only checks an anonymous identifier to verify an active subscription.
Is Psylo free?
No. Psylo is available by subscription through Apple’s in-app purchase system.
Is there a free trial?
Yes. The annual plan includes a 7-day free trial; the monthly plan includes a 3-day trial. Both give full access to all features and the proxy network.
How much bandwidth do I get?
Each subscription includes 200 GB of bandwidth per month, resetting at the start of each calendar month.
Can I use my own proxy servers?
Yes. You can configure your own SOCKS5 or HTTP/HTTPS proxies and assign them to individual silos alongside the built-in Mysk network. You can also use the proxy servers from third-party providers like Mullvad and IVPN.
What platforms is Psylo available on?
Psylo is available for iPhone and iPad. We are evaluating an Android version.
