## What is AI GUARD & BRAKE?

Close selected apps on this iPhone while you are not using them.

GUARD keeps important apps closed, including banking, securities, payment, and IoT appliance apps. BRAKE keeps selected AI apps, such as ChatGPT or Claude, closed. A GUARDed app cannot be opened or operated until you UNLOCK. UNLOCK confirms it is you, then releases the selected GUARD and BRAKE apps together.

This app is not a cloud service that registers your name, address, or phone number. It does not stop an attack that never opens a GUARDed app, an attack that breaks iOS itself, the appliance, the provider's system, another phone, the web, or an action already sent. GUARD / BRAKE remains after the iPhone restarts.

There is a 7-day free trial. After that, the subscription continues and is billed by the App Store. You do not enter a card number in this app. You can review or cancel the subscription in the App Store.
