Every account gets
its own browser.

Sendwin is a multi-account browser: a desktop app for Windows, macOS and Linux, plus a cloud browser you open from any browser. Every account you manage gets its own isolated profile — separate cookies, storage, fingerprint settings and proxy — so client, brand and test accounts stay organised, private and apart, and you can hand teammates access without sharing passwords.

Yes. Creating and launching profiles in the desktop app needs Pro ($19/mo, or $6.99/mo billed annually) or Team ($49/mo, or $20.99/mo billed annually). There is no free trial. You can try the cloud browser first with the free cloud demo — 10 minutes a day, nothing to install, no card — and your first card purchase of a paid plan is covered by a 7-day money-back guarantee.

No. Sendwin does not offer a trial of the desktop app. Two things take the risk out of buying instead: the free cloud demo, which gives you 10 minutes a day in the cloud browser with no card, and the 7-day money-back guarantee on your first card purchase of a paid plan — email support@send.win within 7 days and we refund it, once per customer.

Yes — for accounts you own or are authorised to manage, where that site's own rules allow it: an agency running the ad or social accounts of several clients, a seller with storefronts on more than one marketplace, a support team with test accounts. Each account lives in its own profile, so logins never mix. Using Sendwin to break a website's terms, run fake or bulk-created accounts, evade an enforcement action, scrape, spam, manipulate engagement or commit fraud is prohibited by our Acceptable Use Policy and leads to termination without refund.

Each profile is a separate browser environment with its own cookies, local storage, cache and sessions. The Sendwin engine, a patched Chromium build, gives every profile its own consistent browser fingerprint — canvas, WebGL, audio, fonts and hardware values that stay the same each time that profile opens — and each profile can have its own proxy: its timezone, language and location are set from the proxy's country, and the desktop app updates timezone and location from an HTTP proxy's exit IP at each launch. Nothing carries over from one profile to another.

No. Pro includes 20 residential proxies with 5 GB of bandwidth a month, and Team includes 20 with 20 GB. Extra bandwidth is $6 per GB, and you can bring your own HTTP or SOCKS5 proxies on either plan at no extra charge.

Local-first: a desktop profile's cookies, history and logins live on your own machine. Cloud backups are AES-256-encrypted on your device with a key that never leaves it. Logins you sync or share and per-profile 2FA secrets are stored encrypted on our servers, and proxy settings, including your own proxies' passwords, are stored there too. Cloud browser sessions run on our server in Helsinki, Finland (EU), and keep their cookies there. Sharing a profile with a teammate never reveals the underlying password, and you can set an expiry or revoke access at any time.

Yes — cancel anytime from the portal. Your plan stays active until the end of the billing period, your local profiles stay on your machine, and your first card purchase is covered by a 7-day money-back guarantee.

The desktop app runs on Windows 10 and 11 (64-bit), macOS 12 or newer on Apple Silicon and Intel, and 64-bit Linux. The cloud browser runs in any modern browser with nothing to install.

Not yet. Sendwin runs desktop browser profiles — in the app on Windows, macOS and Linux, and in the cloud browser. There are no Android profiles or cloud phones today. We're deciding whether to build cloud Android profiles: if you'd use them, leave your email and we'll write to you if they launch.

Sendwin is for accounts you own or are authorised to manage. Our Acceptable Use Policy prohibits using it to break a website's terms, run fake or bulk-created accounts, evade an enforcement action, scrape, spam, manipulate engagement or commit fraud. The limits are built in: a fixed number of saved profiles (150 on Pro, 500 on Team), a server-enforced cap of 50 profiles open at once and no bulk account creation, and we do not offer or support an automation API, SDK or headless mode on any plan. Accounts that break the policy are terminated without refund. To report abuse, email support@send.win.
