PRIVACY POLICY

Ground Control · Last updated July 16, 2026

THE SHORT VERSION

Ground Control has no accounts, collects no personal data, and stores no content on any server. Your conversations are end to end encrypted between your Mac and your phone. We cannot read them, and we keep nothing to breach.

WHAT THE APP DOES

Ground Control shows the Claude Code sessions running on your own computer and lets you send them messages from your phone. A small program (the daemon) runs on your Mac, encrypts session information with a key generated on your Mac, and sends it through a relay server to your phone.

WHAT WE CAN AND CANNOT SEE

• The pairing key is created on your Mac and is shared with your phone only through the QR code you scan. It is never sent to us.
• All session content (names, statuses, messages, prompts) is encrypted with ChaCha20 Poly1305 before it leaves your Mac and is decrypted only on your phone.
• The relay server routes encrypted messages by an anonymous channel identifier. It does not store messages, does not log message content, and holds no decryption keys.
• Standard connection metadata (IP addresses, timestamps) is processed transiently by our hosting provider, Cloudflare, to deliver the service.

WHAT WE COLLECT

Nothing. No accounts, no analytics, no advertising identifiers, no crash reporting tied to your identity. The App Store privacy label for Ground Control is "Data Not Collected".

WHAT STAYS ON YOUR DEVICES

• On your Mac: the pairing key (in your home folder) and the daemon itself.
• On your phone: the pairing key and the app. Deleting the app deletes the key.

THIRD PARTIES

The relay runs on Cloudflare Workers. Cloudflare's processing is limited to routing encrypted traffic. No other third parties receive any data.

CHILDREN

Ground Control is a developer tool and is not directed at children under 13.

CHANGES

If this policy changes, the updated version will be posted at this address with a new date.
