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 Android parental-control app that does one job well: manage screen time. No GPS tracking, no web filters, no bloat. -------------------- 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 notification in the system status bar, re-shown if swiped away. 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 full-screen lock Activity 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 capture keystrokes, monitor private messages, read user input, or collect personal/sensitive information from within apps. On-screen text is inspected solely within system Settings and launcher uninstall screens to prevent parental control circumvention. 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. -------------------- WHY PARENTS CHOOSE ZENTRYLOCK • Child Transparency: App block screens show WHY access is restricted and remaining time. No mystery freezes. • One-Tap Extensions: Child requests more minutes; parent approves instantly from their phone. • Offline-First: Rules, caps, and schedules run on the child's device, even without internet. • Built by a Parent: A solo developer creating the tool he needed for his own kids.
