Privacy Policy

GuideWatch collects no data. None. This page explains what that means in practice.

Last updated: 18 July 2026 · Applies to GuideWatch for Apple Watch

The short version

GuideWatch only ever talks to one thing: the NINA instance you point it at, over your own local Wi-Fi network. It has no accounts, no analytics, no telemetry, no advertising, and no server of its own. There is nothing for us to collect, because GuideWatch has no way to send anything anywhere except to the IP address and port you enter.

Data we collect

None. GuideWatch does not collect, transmit, store remotely, sell or share any personal data or usage data. There is nothing to opt in or out of, and no data ever leaves your local network.

The app contains no analytics or crash-reporting frameworks and no third-party SDKs. Its only network activity is the connection you configure to your own NINA instance's Advanced API.

The NINA connection

GuideWatch is a read-only guiding monitor. It requests guiding data from the NINA instance whose address you enter, and displays it - it never sends commands back to NINA, your mount, or any other equipment. This connection happens directly between your Apple Watch and your NINA machine over your local network; it does not pass through any server we operate, because we don't operate one.

Data stored on your Watch

GuideWatch remembers a small amount of configuration locally on-device, using standard iOS/watchOS app storage: the host address and port you connect to, and whether Simulation mode is enabled. That's all it stores. Nothing here is synced to iCloud or anywhere else, and it's deleted if you delete the app.

The iPhone companion app

GuideWatch includes a minimal iPhone app that exists only because Apple requires an installable iPhone component for App Store distribution. It has no functionality beyond a single screen, collects no data, and makes no network connections of its own.

Children's privacy

GuideWatch collects no data from anyone, including children.

Changes to this policy

If a future version of GuideWatch ever changes any of the above, this policy will be updated before that version ships, with the change noted prominently here.
