Antidetect tools ask for the most sensitive thing you own: live sessions for accounts you can't afford to lose. Here is precisely where that data sits, what crosses the network, and what happens if we go away.
Profiles are directories on your own disk, launched by a browser binary installed on your own machine. That's the default path, and it's also the free one - there is no tier where using the product requires uploading a session.
| Data | Where it lives | Does it leave your machine? |
|---|---|---|
| Browser profiles: cookies, localStorage, IndexedDB, history, bookmarks | Your disk | Only if you turn on cloud sync for that specific profile |
| Passkeys / WebAuthn credentials | Your disk, in the profile | Only inside a synced profile archive, same rule as above |
| The fingerprint itself | Generated locally on first launch, stored with the profile | No |
| Page content, form input, screenshots | Your machine | No. We never see what you browse |
| Account email and plan | Our database | Held by us so you can log in and be billed |
| Proxy credentials for managed proxies | Our servers only | Deliberately never sent to your browser - you get an opaque handle |
| Live View frames | Streamed while you have the viewer open | Relayed to your dashboard, not stored |
Marking a profile as synced is a deliberate action on that one profile. It uploads that profile's archive so the identity can roam between your own machines. Every other profile stays where it was created. Delete a synced profile and the cloud copy goes with it.
When you bind one of our residential proxies, the browser is handed an opaque reference, not a host, username and password. The upstream credentials are resolved server-side. A compromised profile or a curious extension has nothing to read.
Every profile exports to a portable archive containing the fingerprint, cookies, storage and passkeys. Local profiles keep launching whether or not you have a subscription, and whether or not our servers answer. There is no phone-home check that turns your identities off.
Page content, keystrokes and screenshots never transit our infrastructure. Live View exists to show you your own session while you watch it, and those frames are relayed, not stored.
Found something this page doesn't describe accurately? That's a bug and we want it reported, not diplomatically hinted at. Write to support@antibrow.com - security reports go to the same inbox and get answered first. For how we handle account data specifically, see the privacy policy.
Unlimited local profiles, no card, nothing uploaded. Turn sync on later if you ever want it.
