Privacy Policy

Last updated 16 October 2026. Applies to Agent Deck for Mac, the Agent Deck iPhone app and the Agent Deck relay, operated by Hyphen Plus Company Limited ("we").

In short

Your Claude Code session data stays on your own devices. When your iPhone connects through our relay, that data is end-to-end encrypted: we can't read it. We don't use analytics, ads or tracking, and we don't sell or share data.

Data on your Mac

Agent Deck for Mac receives events from Claude Code on your Mac (project folder, status, last prompt and tool, model, context use, cost and plan usage). It keeps them on your Mac only, in ~/Library/Application Support/Agent Deck. Connecting to Claude Code adds a hook to Claude Code's settings file; a backup is made first.

Data on the relay

If you sign in on the iPhone app and pair a Mac, our relay at relay.hyphen-plus.com passes data between them. It stores only:

Your account: the anonymous user identifier Sign in with Apple gives us. We don't receive or store your name or email address.
Sign-in tokens for the iPhone app, stored as one-way hashes.
Each paired Mac: a random identifier, the computer's name, and when it was last connected.
Your iPhone's push tokens, so it can update the Live Activity and send alerts.
The latest session summary from each Mac, encrypted with a key that only your Mac and your iPhone have. The relay can't decrypt it.

Push notifications go through Apple's push service. Their visible text is generic (for example "A session needs you"); the session details inside them are encrypted the same way.

Like any web server, the relay and this website keep short-lived technical logs (time, request, IP address) to keep the service running and secure. We don't use them for anything else.

Without an account

If you pair your iPhone with your Mac on the same Wi-Fi without signing in, the two talk directly and nothing goes through our relay.

Deleting your data

In the iPhone app, Delete account removes your relay account, its sign-in tokens and your iPhone's push tokens, and unlinks your Macs. To remove everything on your Mac, disconnect Claude Code in Agent Deck's settings and delete the app and ~/Library/Application Support/Agent Deck.

Children

Agent Deck is a developer tool and isn't directed at children.
