One Browser.Isolated Sessions.Absolute Privacy.
Create your first profile to get started. Each profile keeps its own cookies, sessions, and logins completely separate.

Built for those who can't afford leaks.
Each profile is fully isolated — cookies, sessions, and logins never mix. BlackSession enforces separation at the browser engine level.
Profile Isolation
Every profile runs in a sandboxed container. Cookies, localStorage, IndexedDB, and cache never bleed between identities — by design, not policy.
Secure Sessions
Sessions are cryptographically scoped. Each profile generates its own storage partition key, ensuring authentication tokens cannot be accessed cross-profile.
Multi-Identity Browsing
Maintain simultaneous logged-in sessions across any number of accounts on the same site. Work Gmail, personal Gmail, and client Gmail — all side by side.
Proxy Per Profile
Assign a distinct proxy — SOCKS5, HTTP, or HTTPS — to each profile. Traffic from one identity never shares an IP with another. Network-level isolation included.
All isolation is enforced at the Chromium storage partition level.
One browser. Infinite identities.
BlackSession lets you create isolated browser profiles where cookies, sessions, and logins never mix. Each identity is sealed at the storage-partition level — enforced by the engine, not by trust.
Create a profile
Give it a name and a color. BlackSession provisions a completely fresh Chromium storage partition — no shared state with any other profile.
Assign a proxy
Optionally bind a SOCKS5, HTTP, or HTTPS proxy to the profile. All traffic from that identity routes through its assigned exit — nothing bleeds to the others.
Browse in isolation
Log into any site. Cookies, sessions, tokens, and cached assets are scoped exclusively to this profile. Switch profiles instantly — zero cross-contamination.
