Haven is an Android application designed to enhance personal safety through sensor-based monitoring. It leverages the smartphone's built-in sensors – including accelerometer, camera, microphone, light sensor, and power status – to detect events like motion, sound, and environmental changes. The app records these events locally and sends notifications to the user, providing a proactive security solution.
Haven differentiates itself with its focus on physical security using readily available smartphone hardware. It emphasizes local data storage and encrypted communication for user privacy. The app's design prioritizes a simple, user-friendly interface for configuring sensor monitoring and setting up notification channels. The architecture prioritizes minimal reliance on cloud services, facilitating enhanced security and resilience.
- Sensor Monitoring: Tracks accelerometer, camera, microphone, light, and power events for comprehensive environmental awareness.
- Local Data Storage: Records event logs and media securely on the device, minimizing reliance on external servers.
- Notification Channels: Supports SMS and Signal notifications, allowing users to receive alerts about potential intrusions.
- Remote Access: Enables secure remote access to event logs and captured media through Tor Onion Service.
- Configuration & Sensitivity: Allows users to configure sensor thresholds and notification settings for customized monitoring.
- Background Service: Uses a dedicated background service to handle event monitoring and notifications.
- Privacy Focused: Prioritizes user privacy through local storage, encryption, and minimal data sharing.
Haven is an active open-source project with ongoing development and maintenance. It has a substantial number of stars and forks on GitHub, indicating community interest. Recent commits and issue activity suggest continued improvement. The project documentation is partially complete, with the app's README providing key information. The consistent development indicates a committed active community.
Haven benefits individuals concerned about physical security, investigative journalists, and human rights defenders who need a discreet and privacy-focused way to monitor their surroundings. It provides a valuable alternative to traditional security systems, leveraging existing smartphone technology to offer a cost-effective and easily accessible solution for detecting and responding to potential threats. It enables a new level of security without relying on cloud-based services.
