RelayKit Privacy Policy

Effective 2026-04-25. Publisher: Schalliol Automation LLC.

The short version. RelayKit does not collect, transmit, sell, or share any personal data. All communication is direct between your iPhone and your paired Mac over your local network, or a VPN you control. No analytics, no third-party trackers, no servers operated by us. Keys stay in your Keychain.

What RelayKit stores on your devices

Pairing keys. A private key on your iPhone and its public counterpart on your Mac, in each device's Keychain, so your phone can re-authenticate without rescanning the QR code.
Last-known Mac endpoints. Host names and IPs from the pairing QR, stored in the iPhone Keychain so reconnects work when Bonjour is unavailable (e.g. over a VPN).
Preferences. UI choices (push toggles, last-selected tab) in standard iOS UserDefaults.

All of the above stays on your device. None of it is transmitted to us.

Network behavior

RelayKit only communicates with the RelayKit helper running on your own Mac. Every payload is encrypted end-to-end with Apple CryptoKit — X25519 pairing, HKDF-SHA256 session-key derivation, ChaCha20-Poly1305 framing — before it leaves the phone. There is no relay server, no cloud sync, and no telemetry.

One embedded web view (the Chat tab) loads claude.ai in a standard WKWebView component. When you use that tab, Anthropic's privacy policy governs that activity. We do not inject scripts, proxy, or observe that traffic. The Cowork tab is a fully native session list and does not load any web content.

Permissions RelayKit requests

Camera. Scanning the pairing QR displayed by your Mac. Images are never saved or transmitted.
Local network. Discovering and talking to your Mac over Bonjour / direct IP.
Push notifications. Optional. Used only to alert you when a Claude Code turn completes while the app is backgrounded. The push payload contains a short summary — no source code, prompts, or personally identifiable content ever leaves your Mac.

Children

RelayKit is a developer tool, not directed at children under 13, and we do not knowingly collect information from anyone.

Third parties and trackers

None. No analytics SDKs, no advertising networks, no crash reporters beyond Apple's opt-in TestFlight / App Store Connect diagnostics that you control in iOS Settings → Privacy & Security → Analytics & Improvements.

Data retention and deletion

Because no data leaves your device, there is nothing for us to retain. To remove every trace of RelayKit from your iPhone: delete the app. Pairing keys are wiped from the iOS Keychain automatically at uninstall. On your Mac: quit and delete RelayKit.app, then open Keychain Access and delete any items named "RelayKit" if you want to clear stored pairings as well.

Your rights

We do not hold any personal data about you, so typical data-subject requests under GDPR, the UK GDPR, CCPA/CPRA, and similar laws (access, rectification, erasure, portability, opt-out of "sale" or "sharing") are self-service — delete the app. We do not sell or share personal information for cross-context behavioral advertising. If you believe we've overlooked something, email us and we'll respond.

Changes to this policy

If this policy changes, we'll update the effective date at the top. Material changes will be noted on the RelayKit marketing page and in the next app update's release notes.
