Send.win’s Cloud Features Give Every Profile Its Own Identity

What Are Send.win’s Cloud Features?

Send.win’s cloud features are the set of tools that let you run isolated, persistent browser profiles from any device: unique fingerprints per profile, one-click session sharing without passwords, per-profile proxy routing, and always-on session persistence. Together they let you manage dozens of accounts side by side, without cookies or fingerprints bleeding between them, and without logging back into anything you already opened.

Feature 1: Isolated Browser Profiles

What It Is

Every Send.win profile is a fully isolated cloud browser environment. Each one keeps its own cookies and localStorage, its own canvas/WebGL/user-agent fingerprint, its own cache and history, and its own extension and site settings — completely separate from every other profile in your account.

Why It Matters

Without isolation, websites can link your activity across accounts through shared cookies, a shared fingerprint, or shared localStorage. Send.win’s unlimited virtual profiles make each account look like a genuinely different device to the sites you log into — because from the site’s perspective, it is.

Where Isolated Profiles Help Most

Use Case	How Isolated Profiles Help
Multiple social accounts	Each account lives in its own profile — platforms can’t connect them
E-commerce multi-store	Each store gets its own fingerprint and cookie jar
Agency client accounts	Every client’s logins stay isolated from every other client’s
Research and OSINT	Investigation profiles stay separate from your personal browsing
Ad account management	Each ad account runs in its own environment, reducing link risk

Feature 2: Session Persistence

What It Is

Close a Send.win profile and your session is saved. Reopen it tomorrow, next week, or next month, and everything is exactly where you left it — logged-in accounts stay logged in, tabs stay open, form data stays filled in.

How It Works

Session Lifecycle:
  1. Open profile -> Cloud browser launches with saved state
  2. Browse normally -> Changes save continuously
  3. Close profile -> A snapshot of the session is stored
  4. Reopen later -> Session restores to the exact same state

Saved State Includes:
  - Cookies (auth tokens, preferences)
  - localStorage and sessionStorage
  - Open tabs and their content
  - Browser history and autofill data
  - Extension state

Why It Matters

Without persistence, you’d re-authenticate every account on every visit. For someone running 20 accounts across five platforms, that’s roughly 100 logins per session — persistence removes that overhead entirely; open the profile and you’re already signed in.

Feature 3: One-Click Session Sharing

What It Is

Send.win’s session sharing hands a teammate a fully authenticated browser session in one click. They get working access to the logged-in account — the password never leaves your side.

How It Works

Session Sharing Flow:
  1. Log into a client's account inside a named profile
  2. Click Share -> generate a share link
  3. Send the link to a teammate
  4. They open it and land in the same logged-in session
  5. They work the account without ever seeing the password
  6. Revoke access anytime -> the link stops working immediately

What the recipient gets: full access to the live session, the
same fingerprint and cookies (no new-device security flags).

What the recipient does NOT get: the password, any saved
credentials, profile settings, or the ability to re-share
unless you explicitly allow it.

Session Sharing Use Cases

Scenario	Benefit
Agency team on client social accounts	Clients never hand passwords to staff they don’t fully trust
Freelancer producing content for a client	Client grants temporary access, revokes it when the project ends
Onboarding new team members	Supervised access without permanent credential exposure
Multi-timezone coverage	Day and night shifts work from the same account session
Emergency coverage	A manager can reach a teammate’s sessions while they’re out

Feature 4: Unique Browser Fingerprints

What Gets Fingerprinted

Fingerprint Element	What It Identifies	Send.win Isolation
Canvas fingerprint	GPU rendering behavior	Unique per profile
WebGL fingerprint	Graphics card details	Unique per profile
User-Agent string	Browser and OS version	Unique per profile
Screen resolution	Display characteristics	Unique per profile
Timezone	Approximate location	Configurable per profile
Language settings	Browser locale	Configurable per profile
Installed fonts	System font list	Unique per profile
Hardware concurrency	CPU core count	Unique per profile

Why Automatic Beats Manual

Desktop antidetect tools ask you to hand-configure every fingerprint parameter — screen size, WebGL vendor, canvas noise. Get one detail wrong (say, an iPhone resolution paired with a Windows user-agent) and you’ve created a detectable inconsistency. Send.win generates coherent, realistic fingerprints per profile automatically, so there’s no configuration to get wrong.

Feature 5: Cross-Device Access via Cloud Browser Sessions

Send.win’s cloud browser sessions run entirely on Send.win’s servers and stream to whatever device you open them on — nothing to install for this mode. That’s different from Sendwin Browser, the native desktop app most users run day-to-day for local automation; the cloud sessions are the no-install path when you’re on a machine you don’t control, or just want to check in from a phone.

Device	Access	Notes
Windows PC	Full access via any browser	No install needed for cloud sessions
macOS	Full access via any browser	No install needed for cloud sessions
Linux	Full access via any browser	No install needed for cloud sessions
Chromebook	Full access	Ideal for cloud-first devices
iPad/Tablet	Access via mobile browser	Responsive interface
Mobile phone	Basic access	Screen size limits complex workflows

Why Cross-Device Matters

• Remote work: reach your profiles from home, office, or on the road
• Device failure: if your laptop dies, log in from any other device and keep working
• Team distribution: teammates on different operating systems get an identical experience
• Locked-down machines: works on corporate computers where installing software isn’t an option

Feature 6: Per-Profile Proxy Management

Each profile can carry its own proxy, so the IP address matches where the account is supposed to be logging in from:

Profile Configuration:
  Profile "Facebook US"
    -> Proxy: US residential (Los Angeles)
  Profile "Facebook UK"
    -> Proxy: UK residential (London)
  Profile "Amazon DE"
    -> Proxy: DE residential (Berlin)
  Profile "Personal"
    -> Proxy: none (direct connection)

Social platforms and marketplaces flag logins that arrive from an unexpected country — a Facebook account registered in New York logging in from a German IP is a classic trigger for a security checkpoint. Per-profile proxy assignment keeps every account arriving from where it’s expected to.

How These Features Compare to Other Platforms

Feature	Send.win	Desktop Antidetect Browser	Basic Cloud Browser
Cloud-native sessions	Yes	No (local app)	Yes
Session persistence	Yes, always	Yes	Usually ephemeral
Unique fingerprints	Automatic	Manual configuration	No
Session sharing	One click	Whole-profile sharing only	No
Cross-device access	Any browser, for cloud sessions	Desktop only	Yes
Local resource use	None for cloud sessions	High, per profile	None

The gap that matters most in practice is the middle column: desktop antidetect tools give you fingerprint control, but only if you’re willing to configure each parameter by hand and keep your local machine running every profile you open. A basic cloud browser solves the local-resource problem but usually treats every session as disposable and identical, which defeats the point if the reason you need multiple browsers is to keep multiple accounts from looking related. Send.win is built to close both gaps at once — automatic fingerprints with none of the manual setup, and persistence with none of the local footprint.

Getting Started With Send.win

Quick Start

1. Start your trial: sign up for Send.win’s 30-day free trial — no credit card required
2. Create a profile: name it after the account it will manage
3. Assign a proxy (optional): match it to the account’s expected location
4. Open the profile: a cloud browser session starts right in your tab
5. Log in: sign into the platform you’re managing — this session now persists
6. Close and reopen anytime: your login is saved, so you can pick up exactly where you left off

Naming Profiles Well

Naming Convention:
  [Platform]-[Client/Purpose]-[Account Type]

  Facebook-ClientA-MainPage
  Facebook-ClientA-AdsManager
  Instagram-ClientB-Business
  Amazon-StoreUS-Seller
  Amazon-StoreUK-Seller
  Twitter-PersonalBrand
  LinkedIn-RecruitingTeam

Consistent naming matters more than it sounds like it should once you’re past 10-15 profiles — it’s the difference between finding the right session in two seconds and scrolling through a list guessing. This discipline pays off most for anyone managing multiple accounts for clients rather than themselves.

Security Features Built Into Every Profile

None of the six features above work as a security layer on their own — they compound. A leaked cookie in one profile can’t touch any other profile’s session; a shared link can be revoked the instant you no longer trust the person holding it; and because fingerprints stay stable per profile, you don’t generate the kind of fingerprint churn that trips extra verification checks on the accounts you’re managing.

Security Layer	What It Protects Against
Profile isolation	Cross-profile data leakage between accounts
Cloud execution	Malicious sites reaching your local device
Session sharing without passwords	Credential exposure to team members
Consistent fingerprint per profile	Security flags triggered by fingerprint drift
Persistent sessions	Repeated logins that can trip extra 2FA checks

Frequently Asked Questions

Is Send.win free to use?

Send.win offers a 30-day free trial with no credit card required, so you can try the cloud features above before committing. After the trial, Pro is $6.99/month billed annually and Team is $20.99/month billed annually for larger teams.

Do I need to install anything to use Send.win’s cloud features?

Cloud browser sessions need no local install at all — open the browser tab and you’re in a profile. Sendwin Browser, the native desktop app, is a separate option for anyone who wants local automation via the Automation API; it’s optional, not required for the cloud features covered here.

Is my data safe in Send.win’s cloud?

Each profile is isolated from every other profile and every other user’s account. Session data such as cookies and login tokens is encrypted and tied to your account only, and any shared session can be revoked instantly.

How many profiles can I create?

Profile limits scale with your plan — Pro and Team both raise the ceiling well past what a solo user typically needs. For unlimited virtual profiles, choose the plan tier that matches how many accounts you’re actually running.

Can I use Send.win for ad account management?

Yes — this is one of the most common uses. Create one profile per ad account (Facebook Ads, Google Ads, TikTok Ads), attach a location-matched proxy to each, and every ad account operates in its own isolated environment.

Does Send.win offer an API for automation?

Yes. The Automation API supports Selenium, Puppeteer, and Playwright against Sendwin Browser profiles, and it’s available starting on the Pro plan rather than being restricted to Team.

Can I share a session with someone who doesn’t have a Send.win account?

Session sharing is designed for teammates inside your workspace. External collaborators typically need to be added to your team first, at which point you can share a specific profile’s session with them directly.

What happens to my sessions if I cancel my subscription?

Your profiles and their saved sessions remain associated with your account; access to open and use them depends on staying on an active plan, the same way most subscription cloud tools work.

Conclusion

Send.win’s cloud features work together rather than as a pile of separate options: isolated profiles with automatic fingerprints stop accounts from being linked, session persistence removes repeat logins, one-click sharing lets teams collaborate without passwords changing hands, and per-profile proxies keep every account arriving from where it’s expected to. Add cross-device access for the cloud sessions and per-profile security, and you get infrastructure built specifically for running more than one account at a time — safely, and from whatever device is in front of you.
