A Smarter Way to Manage Browser Profiles and Team Workflows.

Organize separate browser profiles for multiple accounts, configure dedicated proxies, collaborate seamlessly with team members, and customize interfaces with Hide Element controls. Optimized for Android smartphones and PC emulators (LDPlayer, Nox, BlueStacks).

On Android devices and tablets, UCloak partitions storage and credentials per profile. Sessions delegated through Workplaces on PC emulators synchronize cookies and settings seamlessly.

Working with your profiles

Android app & PC emulators

Isolated profile containers

Every profile runs in an independent sandbox with isolated cookies, localStorage, IndexedDB and cache. Run concurrent profiles across advertising networks without cross-account contamination.

Profile management

// Profile Container Descriptor
{
"profile_id": "prof_meta_042",
"sandbox": true,
"storage": {
  "cookies": 34,
  "cache_partition": "isolated_042"
},
"fingerprint": { "canvas": "NOISE", "webrtc": "BLOCK_UDP" }
}

Proxy engine and pre-flight checks

Connect via HTTP, HTTPS or SOCKS5 with IP whitelist or user/pass authentication. Pre-flight checks test latency, verify IP geolocation and detect proxy failures before launching the browser.

Proxy setup

# Pre-flight proxy audit log
✓ SOCKS5 Handshake: 38ms (socks5://us-res.proxy.net:1080)
→ Egress IP: 198.51.100.24 [United States / Comcast Cable]
→ WebRTC Shield: STUN requests blocked (Zero-Leak)
→ Timezone auto-sync: America/New_York (UTC-05:00)

Hide Element engine

Redact sensitive financial balances, credit card numbers and merchant revenues directly in the DOM. Team members and virtual assistants can manage campaigns without viewing billing credentials.

Hide Element documentation

/* Injected DOM Redaction Rules */
.billing-balance, [data-testid="ad-spend"], .card-number {
filter: blur(8px);
pointer-events: none;
user-select: none;
}

Workplace sharing and permissions

Organize profiles into Workplaces and delegate access with four roles: Owner, Admin, Member, and Viewer. Share active authenticated sessions without exposing account passwords or 2FA seeds.

Cloud sync and emulator concurrency

Work on an Android smartphone or run dozens of instances simultaneously inside LDPlayer, Nox or BlueStacks. Bookmarks, proxy bindings and session tokens synchronize encrypted in real time.

Emulator setup

# Active Emulator Instances
Instance 01 [LDPlayer-9]: Running (Profile: ad_us_01)
Instance 02 [LDPlayer-9]: Running (Profile: ad_us_02)
Instance 03 [NoxPlayer-64]: Running (Profile: ad_uk_01)
→ Cloud Checkpoint: Encrypted AES-256 (0 sync conflicts)

Shield Levels

Set a Shield Level for each profile. Standard isolates storage. Deep Masking injects sub-pixel noise into Canvas and WebGL. Strict Zero-Leak halts traffic if the proxy drops.

Standard Shield
E-Commerce & Storefronts

Cookie, IndexedDB and persistent cache isolation. Automatic timezone alignment to proxy IP. Ideal for high-speed multi-store storefront management.

Deep Masking
Meta, Google & TikTok Campaigns

Sub-pixel noise on Canvas 2D/3D and AudioContext. Dynamic WebGL vendor spoofing, font query interception, and Client Hints header synchronization.

Strict Zero-Leak
Compliance & Anti-Leak

Hardware-level proxy kill-switch. Blocks all non-proxy fallback network traffic. Disables WebRTC UDP queries entirely to prevent IP exposure.

Shield levels can be configured per profile or enforced across an entire Workplace group.

Platforms and automation

UCloak for Android & PC Emulators

The native client, optimized for ARM64 and x86_64. Native Android runtime with lower memory footprint than Electron desktop wrappers. Runs smoothly on physical devices and emulators.

Download builds

REST API and OpenAPI 3.0

Automate profile lifecycles, residential proxy rotation and cookie ingestion from your custom scripts through standardized OpenAPI 3.0 endpoints.

API Reference

Bring your proxies

Importing proxies and cookies is built into the client.
Batch proxy import

Import proxy lists from raw text, CSV or clipboard supporting ip:port:user:pass and socks5:// URIs from any residential provider.

Cookie session transfer

Import cookies in JSON or Netscape format exported from desktop anti-detect suites to resume authenticated sessions without re-authenticating.

Technical questions

How does UCloak differ from standard browser Incognito mode?
Incognito mode only clears cookies upon closing but exposes your real IP, WebGL GPU, canvas hash, system fonts and audio latency. UCloak operates at the engine level to mask and isolate digital hardware identifiers.
What devices and emulators are supported?
UCloak supports physical Android devices running Android 8.0 up to Android 15 (Samsung, Xiaomi, Pixel) and desktop PC emulators including LDPlayer 9, NoxPlayer, BlueStacks 5, and Genymotion.
How does the Hide Element engine work?
Hide Element selectively overrides visibility rules on targeted DOM elements (balances, credit cards) without interrupting page scripts or form workflows. Team members manage campaigns without viewing financial data.
How does UCloak prevent IP leaks when proxy connections fail?
UCloak blocks WebRTC STUN/TURN queries and resolves DNS strictly via the proxy tunnel. Under Strict Zero-Leak, a network kill-switch halts outgoing traffic if proxy connectivity drops.
Can I share profiles without exposing master passwords?
Yes. Delegating profile access through a Workplace allows teammates to launch pre-authenticated sessions with persistent cookies without exposing plain-text credentials or 2FA codes.
