Privacy Policy

Last updated: December 21, 2025

At Langblocker ("we", "us", or "our"), we take your privacy seriously. This Privacy Policy explains how we collect, use, and protect your information when you use our mobile application (the "App").

1. Data Collection

We believe your data belongs to you. Langblocker is designed to operate primarily on your device.

• Usage Data: We use Apple's Screen Time API (DeviceActivity) to monitor your app usage locally. This data never leaves your device.
• Learning Progress: Your vocabulary progress is stored locally on your device or in your private iCloud container.

2. Data Usage

We do not sell your data. We do not use your usage habits for advertising.

3. Third-Party Services

We may use anonymous analytics to improve app stability (e.g., crash reporting), but this does not include personal identifiers or your specific app usage history.

4. Contact Us
