Privacy & security

• Your messages, contacts, calendar, reminders, photos, and files are read on your device and never uploaded by Twinly, apart from the parts a task needs, as below.
• Your voice clone is built and stored on your Mac by Twinly Voice. Your voice is never sent anywhere, and no third-party voice service is used.
• Your learned memory, pathways, and failure history live on your device.
• Credentials you add (the Gmail app password, connector sign-ins, a beta build's provider key) are stored in your OS keychain.

To reason about a task, the twin sends the engine the relevant context: the request, the draft it is writing, the part of the screen or page it is reading. On the managed Twinly engine that content routes through Twinly's servers to the AI infrastructure providers running the engine's models, only to generate the response, never to train models. On a bring-your-own-key beta build it goes directly to the provider whose key you set.

If you sign in, Twinly also processes your account email, subscription and usage records for billing, and, while usage sharing is on, diagnostic telemetry that can include your task prompts; usage sharing switches off in Settings. The precise list is in the Privacy Policy.

Email goes directly to Google's servers over an encrypted connection; texts go out through your Messages app; calls go over your Google Voice line. The optional Chrome extension passes only the tab Twinly opened for your task to the Twinly app on the same computer.

That is your choice: Ask me every time, Ask before it ships, or Don't ask (the default, where each text or email shows for 5 seconds before it goes). In every mode, messages to family, payments over your limit, and the twin's questions wait for you. The modes, the send preview, and undo are explained in Approvals and control.

• Type a password, a card number, or an ID number like a Social Security number into a field.
• Solve a CAPTCHA or robot check.
• Permanently delete your files: anything it removes goes to the Trash.
• Act on a request from someone else who texts @twinly. Only your own requests make it act; others get a short reply that shares nothing private about you.
• Run an AI in the background watching you. Its suggestions come from reading your own calendar and mail locally.

• Stop a running task from the island or the app, instantly.
• End a call from the island at any moment.
• Decline an approval and nothing goes out.
• Undo a calendar, reminder or file change for 30 minutes from Already done.
• Turn off @twinly, learned pathways, or suggestions with their switches.
• Quit the app and the twin does nothing until you reopen it.
