Privacy Policy
This Privacy Policy applies to the Rattle: Real Dice Cup iOS application and its official website https://rattle.cometseek.com, published by Hangzhou Duandian Xunji Technology Co., Ltd. (Cometseek, “we”). Our rule is simple: Rattle runs entirely on your device and collects zero personal data.
1. Zero Personal Data Collection
Rattle requires no user account, operates no backend servers, and embeds zero third-party analytics, crash-reporting, advertising, or cross-app tracking SDKs. We never collect, inspect, store, or sell your personal information or usage activity.
2. On-Device Processing Only
- Motion Sensors (CoreMotion): Accelerometer and gyroscope readings are processed in volatile memory solely while the app is open to drive 3D rigid-body dice physics and face-down lid locking. Motion data is never recorded or transmitted.
- Local Preferences (UserDefaults / App Group): Your chosen cup vessel, dice count, sound/haptic toggles, and widget state are stored locally inside your iPhone's app sandbox and shared App Group container. Uninstalling Rattle removes all stored preferences.
- Real-Time Audio & Haptics: All acoustic impacts are synthesized locally at 48 kHz on your iPhone CPU without network streaming or microphone access.
3. In-App Purchases (StoreKit 2)
The optional one-time “Rattle Pro” unlock is processed directly by Apple via StoreKit 2. We never receive or store your payment card details or billing address.
4. Official Website & Support Email
- This website consists of static HTML and CSS with zero cookies, scripts, or analytics trackers. Standard short-lived web server access logs (IP address, timestamp, requested path) are retained briefly solely for security and troubleshooting.
- If you email us at rattle@cometseek.com, we use your email address and message solely to reply to your inquiry.
5. Children's Privacy & Updates
Rattle is rated 4+ and collects no personal data from anyone, including children. Material updates to this policy will be posted on this page with a revised date.
