Privacy Policy - Lock Alarm

This Privacy Policy applies to the mobile application Lock Alarm - Re: U ("the App") provided by the Lock Alarm - Re: U operator ("the Provider"). The App is provided on an "AS IS" basis.

1. Information Collection and Use

The App does not require user registration and does not directly collect any personally identifiable information. However, the following limited technical information may be automatically collected by the operating system or standard system features for the purpose of ensuring proper operation and quality improvement:

Device type
OS version
App stability information (crash logs, etc.)

The App does not collect location data (including precise location). The App does not access the camera, microphone, contacts, or photo library. Please note that third-party advertising services may collect technical information in connection with ad display.

2. Use of Screen Time API

The App uses the iOS Screen Time API (FamilyControls / ManagedSettings / DeviceActivityMonitor) to provide app usage restriction features.

Information about apps selected by the user is stored on the device only as opaque tokens (ApplicationToken). The Provider cannot view or obtain app names or usage data.
All data acquired and processed through the Screen Time API remains on the user's device and is never transmitted to external servers.
Use of this feature requires the user to grant Family Controls permission.
