ZentryLock Screen Time Control

Parental control without the bloat. Block apps, set screen time limits, and lock your child's phone remotely — all from your own device or web dashboard.

ZentryLock is a focused parental-control app for Android that does one job exceptionally well: manage screen time. No GPS tracking, web filters, or bloat — just real control that works.


IMPORTANT POLICY DISCLOSURE & ACCESSIBILITY SERVICE USAGE
---------------------------------------------------------
To comply with Google Play Policies (Stalkerware & Accessibility Services), ZentryLock enforces strict transparency and user safety guidelines:

1. PARENTAL MONITORING TRANSPARENCY:
• ZentryLock is a dedicated parental control and screen time monitoring application designed exclusively for parents and guardians.
• When active on a managed child device, the app displays a persistent, non-dismissible notification in the system status bar. This ensures the device user is always aware that screen time control and application rules are active.

2. Android ACCESSIBILITYSERVICE API USAGE:
• ZentryLock requires the AccessibilityService API to function.
• Why we use it: The Accessibility Service intercepts window state changes to detect in real-time which app is currently open in the foreground on the child's device.
• What it does: It compares the foreground package name against parental blocking lists, daily usage limits, and screen-free schedules configured by the parent. If a rule is violated, it launches the secure lock screen overlay to block access. It is also used to prevent children from circumventing settings or disabling parental controls without authorization.
• What it DOES NOT do: The Accessibility Service is never used to read screen contents, capture keystrokes, monitor private messages, or collect any personal/sensitive information. No data accessed via this API is shared or transmitted outside the parent-paired connection.

By installing and enabling ZentryLock, you acknowledge and consent to the use of the AccessibilityService API for local app-blocking and parental control purposes.
