From "monitoring" to "AI-powered monitoring." KIZUNA Guard is a next-generation family security app that utilizes the latest AI technology to prevent smartphone troubles before they happen.

[KIZUNA Guard's Three Core Features]

✅ 1. AI Screenshot Analysis (Purpose of Image and Video Permissions) AI automatically analyzes screenshots saved by children as evidence of bullying or signs of potential trouble in the background. ・The content of "disappearing messages" and "in-game chats," which do not remain as text data, is inspected the moment they are saved as images. ・Parents will only be notified if the image contains signs of "bullying," "invitations to commit crimes," or "financial trouble."
*This is a core feature of this app. Photo permissions are used to automatically detect images in the background.

✅ 2. Context-Aware AI Message Detection: Rather than simply matching keywords, AI (Gemini Pro) performs advanced context analysis. It accurately detects warning signs such as "bullying," "suicide/SOS," and "phishing scams." ・For children: Gently warn them on the screen and encourage self-control. ・For parents: Notify them only when the risk is high. Privacy of everyday conversations is protected.

✅ 3. Measures to combat children's smartphone addiction and troubles: ・Harmful site blocking: Automatically blocks dangerous adult and criminal sites. ・App usage restrictions: Set time limits to prevent overuse and block the launch of dangerous apps.

[Other Safety Features] ・Location Tracking: Check your child's location in real time. ・SOS Notification: Send location and messages to all family members in an emergency. ・Uninstall Prevention: Prevent children from unauthorized app deletion. ・Cross-Platform Support: Parents can remotely change settings from their device.

[Privacy and Security] We employ the highest level of security technology to protect your precious family's data. ・Communication encryption: All data is encrypted before transmission using SSL/TLS. ・Log encryption: Detected dangerous messages are encrypted and stored so only family members can view them. ・Unnecessary data is not stored: Daily conversations and image logs deemed "safe" by AI are not stored on the server.

[About the use of accessibility features (Accessibility Service API)] KIZUNA Guard uses the Accessibility Service API to provide the following functions:

To read text displayed on the screen (social media messages and website content) and use AI to detect dangerous content (bullying, scams, invitations to commit crimes, etc.).

To detect the use of dangerous websites and apps and activate the blocking function.

To prevent accidental app operation and unauthorized uninstallation. *The acquired data is used only to determine danger detection. Data deemed safe by AI is not stored on the server or provided to third parties.

Protecting family ties with technology.
