FAQ

Frequently asked questions.

What is the Kai help chain?

The help chain is Kai's core feature. One silent trigger starts it: all your trusted contacts instantly receive an SMS with your exact location as an Apple Maps link, and Kai automatically calls your primary contact. Start it with a Siri voice command, the safety button, a check-in timer, the lock screen, or fall detection.

How does Kai share my location with my contacts?

The moment your help chain starts, Kai reads your current GPS position on your iPhone and adds it to the SMS as an Apple Maps link. Your contacts tap the link and see exactly where you are, on any phone. Your location goes only to the contacts you chose, never to our servers.

How does Kai work without an internet connection?

Kai runs entirely on your iPhone. SMS alerts, phone calls, location sharing, fall detection, and voice commands all use native iOS capabilities that work offline. Your safety never depends on Wi-Fi or cellular data.

Do my contacts need to install an app?

No. When you trigger an alert, Kai sends a standard SMS with your current location and places a regular phone call. Your contacts receive help requests on any phone. No app required.

Is Kai available outside the Apple ecosystem?

Kai is available for iPhone and iPad, and works with Apple Watch for fall detection and vital signs monitoring. It is deeply integrated with iOS features like Siri, Dynamic Island, Live Activities, and HealthKit. There are no plans for Android at this time.

How is my data kept private?

All your data stays exclusively on your device. Contacts, vital signs, and location history never leave your iPhone. Kai has no cloud backend, no servers, no accounts, and no data collection.

What happens if I accidentally trigger an alert?

Kai includes a short countdown before sending alerts, giving you time to cancel if it was a false alarm.
