H2 Kiosk Lock App

H2 Kiosk Lock ("we", "our", or "the app") is developed by H2-AI GmbH. This privacy policy explains how we handle your data.

Data Collection

We do not collect any personal data.

H2 Kiosk Lock operates entirely on your device. All settings, including your PIN and app preferences, are stored locally on your device and are never transmitted to any server.

Data Storage

• PIN: Stored locally on your device in encrypted form (SHA-256 hash)
• Settings: Stored locally using Android DataStore
• Selected Apps: Stored locally on your device

No data leaves your device.

In-App Purchases

Premium purchases are processed through Google Play. We do not have access to your payment information. Please refer to Google's Privacy Policy for information about how Google handles payment data.

Permissions

H2 Kiosk Lock requires certain permissions to function:

• Accessibility Service: Required to detect and block system navigation when kiosk mode is active
• Display Over Other Apps: Required to show the kiosk overlay
• Boot Completed: Optional, to auto-start kiosk mode after device restart

These permissions are used solely for kiosk functionality and not for data collection.

Third-Party Services

The app uses Google Play Billing for in-app purchases. No other third-party services are integrated.

Children's Privacy

H2 Kiosk Lock is not directed at children under 13. We do not knowingly collect data from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date.
