Twoyi TWINPrivacy policy
In short: Twoyi runs no model servers of its own and does not collect usage data. When your Twin works on a task, screen content goes to the model provider you choose and set up. Everything else stays on your phone.
1. Data that stays on your phone
- Model connections: endpoint, model name and API key. The key is encrypted on the device and never uploaded to Twoyi.
- The Twin phone: apps you install there, accounts you sign in to and the data they create live in Twoyi's app storage, and are deleted when you uninstall Twoyi.
- Chats, memory and task steps: stored on the device. You can view and delete memory in Settings → Memory; task steps are kept only for the last few tasks.
2. Data sent to your model provider
Your Twin needs a large language model to understand you and decide what to do next. The provider you connect (for example OpenAI, DeepSeek, or your own endpoint) receives:
- your messages to the Twin, the conversation so far and your memory;
- during a task, the text and layout of the Twin phone's current screen and the steps already taken;
- with “See the screen” on, screenshots when needed;
- in “use this phone” mode (root or Shizuku), the same screen content, taken from the real apps on your phone that the Twin works in.
The app sends this straight to the endpoint you set up, not through Twoyi's servers. How the provider stores and uses it is governed by that provider's own privacy policy and terms; please read them before you choose one.
For logins, passwords, verification codes and payment PINs, your Twin stops and asks you to handle them, and password fields are usually masked in the screen layout. Please note that the Twin cannot recognise every kind of sensitive information: anything else on screen during a task, such as chats, orders or addresses, may be sent to the model. If you do not want something seen, do not ask the Twin to work there.
3. Logs you choose to send
Only when you tap “Send logs” in settings does Twoyi pack its run logs and the steps of recent tasks, and hand the package to an app you pick in the system share sheet (for example Telegram or email). These records may contain text seen on screen during tasks. You decide whether and to whom to send them.
4. Other network use
- Apps inside the Twin phone go online directly, as on any phone; their own privacy policies apply.
- If you choose to install add-ons such as Google services in settings, Twoyi reads a download configuration from twoyi.app and downloads the package.
- When you open Twoyi, and when you tap “Check for updates” in About, the app reads a version file from twoyi.ai to see whether a new version is out. The request carries no account or device identifier, only what any web request carries, such as your IP address.
- Twoyi contains no advertising SDKs and no third-party analytics or crash-reporting SDKs.
5. System permissions
Twoyi asks for camera, microphone, location, Bluetooth, notification and similar permissions when needed, so that apps inside the Twin phone can use those features (for example scanning a code or sending a voice message). You can turn them off in system settings at any time; the matching features inside the Twin phone then stop working. For “use this phone” mode, Twoyi needs root or Shizuku access to create the background screen and operate apps on it.
6. Your choices
- Change or delete model connections at any time.
- Turn off options such as “See the screen” or “Ask before risky actions” in settings.
- Delete memory, or clear Twoyi's data or uninstall it to remove all local data.
7. Children
Twoyi is not directed at children under 14.
8. Changes and contact
When this policy changes, we update the date at the top of this page and post a note in the Telegram channel. For questions, write to twsxtd@gmail.com.
