# Sync & Devices

**Q. How does sync work?** A. Encrypted blobs sync via **Oten Cloud** with conflict-aware versioning. Only ciphertext moves — keys and plaintext never leave your device.

**Q. Is anything readable during sync?** A. No. Sync traffic is ciphertext plus opaque metadata. Zero plaintext leaves the device.

**Q. How do I set up a second device?** A. Install the app, sign in with the same Oten account, import your **User Recovery Key**, and the vault list pulls automatically. Open each vault with its password. See [Add a new device](https://file+.vscode-resource.vscode-cdn.net/Users/mando/Silver%20Tiger/stealth-vault/product-docs/user-guide/playbooks/add-a-new-device.md).

**Q. Why aren't my changes showing on another device?** A. Check connectivity and that **sync is enabled** for the vault. Background pulls run silently; a manual pull shows a loading state. Give it a moment after reconnecting.

**Q. Can I turn sync off?** A. Yes, per vault. Note that **key rotation requires sync to be enabled**, and other devices won't update while sync is off.

**Q. What is "Transfer Drive"?** A. Moving or reassigning your Drive to another device or owner, while your Vault data stays isolated. See [Transfer a Drive](https://file+.vscode-resource.vscode-cdn.net/Users/mando/Silver%20Tiger/stealth-vault/product-docs/user-guide/playbooks/transfer-a-drive.md).

**Q. Can I share with people on other devices?** A. Yes — share files/folders (Drive) or a whole vault with up to 5 recipients, password-protected and expiration-controlled, as Viewer or Editor.
