Start with a separate workspace, minimal permissions and a clear map of where data goes. Self-hosting the agent is only one part of privacy. Test access controls and recovery before connecting personal accounts or allowing unattended work.
1. Draw the data path before signing in
List the client device, rented host, model endpoint, chat service, tools and backup destinations. For each step, record what it receives and how access can be revoked. Treat conversations, stored memory, browser sessions and generated files as potentially sensitive.
An agent hosted in Singapore does not mean every provider it calls processes data in Singapore. If your goal is inference on the rented machine, check model fallbacks and auxiliary services as well as the main endpoint. External search and chat integrations remain external even with a local model.

2. Keep access specific to one person and machine
Use a private access path with an MFA-capable identity layer. Keep admin interfaces off public internet ports and retain application authentication. For chat access, restrict who can invoke the agent. Do not use one gateway and shared credentials for unrelated customers.
OpenClaw’s security documentation describes a trusted operator boundary, not hostile multi-tenant isolation. A private network also needs access rules: merely joining devices to the same network does not restrict them to their assigned machine.

3. Restrict tools and prove that the limits work
Begin without valuable credentials. Use a dedicated operating-system account and a disposable working folder; select and verify an isolated execution backend where supported. Limit writable mounts and network destinations. Do not pass the host’s administrator credentials or container-management socket to the agent.
Review installed skills and plugins as software with access to your environment. Keep human approval for consequential actions, and deny those actions when unattended approval is unavailable. Untrusted webpages, messages and documents can try to redirect an agent; a friendly persona or an instruction to be careful is not an access control.
- Confirm that an unknown sender cannot start a task.
- Use dummy files to test that the agent cannot read outside its allowed workspace.
- Verify that a blocked send, delete or purchase stays blocked during scheduled execution.
- Test that revoking an account or key also prevents further access.

4. Make the workspace replaceable
Keep an independent, protected backup of necessary agent state and project files. Exclude secrets from repositories and support screenshots. Test a restore into a clean environment with dummy credentials, then document who patches software and who can stop a runaway task.
Before cancellation, export and verify your files, disconnect integrations and revoke provider keys. Deleting a local chat is not proof that copies were removed from model providers or messaging services. Confirm their retention controls separately.
This is a proposed pilot checklist, not a security certification or an installed HelloMiniPC feature. Hosted hardware remains subject to operator administration. Agree on support access and data handling before placing sensitive material on it.
