ClosedHand is built on a simple principle: your data is yours. We don't sell it, we don't harvest it, and we don't monetise you. ClosedHand is a free, independent project with no investors, no ads, and no hidden agenda.
ClosedHand is an AI assistant that connects to your services, runs background agents on your behalf, and can optionally access your local computer. It works across chat platforms (WhatsApp, Telegram, Discord, Slack, LINE) and via the web at closedhand.ai. It is operated as a purpose-driven, independent project. We are not affiliated with any big tech company.
Account information: Your name and email address when you connect via Google or Microsoft. This is used to identify your account and nothing else.
Service connections: When you connect services like Gmail, Google Calendar, Slack, Shopify, or others, we store the authentication tokens needed to access those services on your behalf. These tokens allow ClosedHand to read and act on your data only when you ask, or when you have enabled proactive features like Pulse.
Conversation history: Your messages with ClosedHand are stored so the assistant can maintain context across conversations. This history is encrypted at rest and in transit.
Context Brain: Things ClosedHand learns about you (preferences, key contacts, important dates, project notes) are stored in your personal Context Brain. You can view, edit, and delete any of this at any time from your dashboard.
Location data: If you share your location, it is stored to help with location-based requests. Location data is used only for the specific request and retained only to avoid asking you repeatedly.
Worker and agent data: When you create scheduled workers or team projects, the task descriptions, results, and status are stored in your account. These are visible on your dashboard and deletable at any time.
If you install the ClosedHand Bridge app on your Mac or PC, ClosedHand can access your local files, terminal, and applications. This is entirely optional and requires explicit setup on your part.
What Bridge can access: Files and folders you have given permission to, terminal/shell commands, Apple Mail, Calendar, Reminders, Contacts, Notes, and screen content. Each category has its own permission toggle that you control.
How it works: Bridge connects your computer to ClosedHand via a secure WebSocket connection. Data flows directly between your machine and our servers. We do not store your local files on our servers. File contents are read in real-time when requested and are not persisted beyond the immediate processing of your request.
You are in control: You can disconnect Bridge at any time. You can toggle individual permissions (Mail, Files, Terminal, etc.) on or off from your dashboard. When Bridge is not running, ClosedHand has zero access to your computer.
ClosedHand provides a cloud-based sandbox environment for running code, processing data, and browsing the web. This environment is isolated and temporary. Code execution happens in a sandboxed container that is destroyed after use. No persistent data is retained from sandbox sessions unless you explicitly save results to your Context Brain.
You can extend ClosedHand by installing skills (instruction files) and MCP connections (external tool servers). All skills and MCP connections are scanned for security risks before activation. MCP servers are third-party services that you choose to connect. Their own privacy policies apply to data they process.
We do not track your browsing outside of ClosedHand. We do not collect analytics or behavioural data. We do not build advertising profiles. We do not share your data with third parties for any commercial purpose. We do not use your data to train AI models.
Your data is used for exactly one purpose: to make ClosedHand useful to you. When you ask ClosedHand to check your email, it reads your email. When you ask about your calendar, it looks at your calendar. When you enable Pulse, ClosedHand periodically checks your connected services to alert you about things that need your attention. When you run a team project, ClosedHand coordinates multiple workers on your behalf and stores the results.
ClosedHand uses Anthropic's Claude AI models to understand your requests and generate responses. Your messages and relevant service data are sent to Anthropic's API for processing. Anthropic does not use API inputs to train their models. Your conversations are not used to improve AI systems. ClosedHand automatically selects the most appropriate model for each request.
All data is encrypted in transit (TLS) and at rest. Authentication tokens for connected services are stored securely. Bridge connections use secure WebSocket with token-based authentication. We use industry-standard security practices for all data handling. Destructive actions (sending emails, deleting events, running shell commands) require your explicit confirmation before execution.
You can view everything ClosedHand holds about you at any time from your dashboard. You can wipe all your data at any moment from Settings. If your account is inactive for an extended period, we will delete your data automatically. When you delete your data, it is gone. We do not keep backups of deleted data.
ClosedHand connects to third-party services (Google, Microsoft, Slack, Shopify, Meta, GitHub, and others) using their official APIs and OAuth flows. When you connect a service, you authorise ClosedHand through that service's own consent screen. You can revoke access at any time from your dashboard or from the third-party service directly.
ClosedHand uses AI models from Anthropic (Claude) to process your messages. Anthropic's API terms state that they do not train on data sent through their API. Your conversations are processed, not stored or learned from. You can read Anthropic's data policy at anthropic.com/policies. We are exploring options for users to bring their own API keys or use local models so your data never leaves your machine.
ClosedHand is a free, independent project. There are no investors, no shareholders, and no advertising. We will never sell user data or introduce hidden monetisation. If ClosedHand ever charges for anything, it will be transparent and optional.
You have the right to access all data we hold about you. You have the right to delete all your data at any time. You have the right to disconnect any service at any time. You have the right to export your data. If you are in the UK or EU, you have additional rights under GDPR, and we respect all of them.
If we make meaningful changes to this policy, we will notify you through ClosedHand directly. We will never quietly weaken your privacy protections.
If you have questions about your privacy or your data, send a message to ClosedHand using /feedback, or email [email protected].
