Login & Subscription

Login methods

You can sign in with Google, Apple, or email/password — or skip signing in entirely and use Flash Translate as a guest. Guest mode gives you full access to all three translation features, with up to 2 saved LLM configurations and no cross-device sync.

Subscription & cloud sync

Signing in doesn’t require a subscription — a signed-in free account still has the same 2-configuration limit as guest mode. Subscribing (see Pricing) removes that cap and turns on real-time cloud sync: your LLM configurations, including API keys (end-to-end encrypted in transit), sync automatically across every device where you’re signed in.

If your subscription lapses

Your cloud data isn’t deleted when a subscription ends or is cancelled. You get a short grace period during which the extension can still fetch your existing cloud-stored configuration down to a device — after that grace period is used up, you’ll need to re-enter your API key manually on any device that hasn’t already synced it locally. When this happens, a dialog prompts you to choose whether to keep or clear your locally stored configurations.

Signing out

Signing out always clears your login session. You’re asked whether to also clear your locally stored LLM configurations, or keep them (re-encrypted locally) for continued use in guest mode. Your app settings (language, feature toggles, etc.) and local translation logs are never affected by signing out — they’re device-local and not tied to your account.

See the Refund Policy for what happens to billing when you cancel.
