Sentra is a modern behavioral monitoring platform designed to protect children in the age of AI. Unlike traditional parental controls that rely on invasive content scanning, Sentra uses Zero-Knowledge Behavioral Signals to identify risks in AI chatbot interactions and app usage patterns without ever reading private messages.
Sentra fills the "AI Safety Gap" by monitoring how children interact with LLMs (Claude, ChatGPT, Character.AI). It detects:
- Romantic Roleplay Patterns: Guarding against emotional dependency on AI.
- Jailbreak Attempts: Monitoring for bypasses of safety filters.
- Harmful Advice: Identifying when AI provides potentially dangerous guidance.
- Privacy Leaks: Preventing children from sharing PII with chatbots.
The Sentra Dashboard provides a high-level overview of family activity, risk trends, and real-time alerts.
- Multi-Child Support: Manage monitoring for the whole family from one interface.
- Activity Logs: Review behavioral signals across 7-day or 30-day windows.
- Weekly Digests: Get automated reports on screen time and risk categories.
- Real-time Alerts: Critical notifications via email and push when high-risk patterns are detected.
Sentra is built for privacy, performance, and scalability.

To test the dashboard with realistic data without a physical device:
node src/simulator.jsSentra follows a Privacy-by-Design approach:
- Metadata Only: We never store or transmit the body of children's messages.
- Local Analysis: Future versions aim to move AI analysis entirely on-device.
- COPPA Compliant: Built-in parental consent workflows and data purge cycles.
