1. Information Collection and Use
ZERO is an offline-first polar puzzle game. We **do not** require you to create an account, register, or provide personal identity details (such as your name, email, or physical address) to play the game.
However, the Game utilizes third-party services that may collect information used to identify your device for advertising, analytics, and payment processing.
Third-Party Service Providers:
* Google AdMob & Google User Messaging Platform (UMP):
Used to display personalized and non-personalized advertisements, track ad performance, and handle privacy consent in accordance with GDPR and Apple App Tracking Transparency (ATT).
AdMob may collect:
- Device identifiers (such as IDFA or Android Advertising ID)
- IP address and coarse location
- Interaction and diagnostic data (ad impressions, clicks, crash logs)
[Google Privacy Policy](https://policies.google.com/privacy)
* Apple App Store & StoreKit:
Used to process in-app purchases (such as the "Remove Ads" package) and securely verify transaction entitlements via StoreKit 2. We do not store or process your credit card or billing information; all financial transactions are handled directly by Apple.

2. Local Device Storage & Keychain
Game progress, unlocked levels, and consumable hints are stored locally on your device. Critical monetization attributes (such as the ad-free entitlement) are securely hashed and stored in your device's hardware-backed **iOS Keychain** to prevent unauthorized tampering. None of this data is transmitted to external servers operated by us.

3. Children’s Privacy
ZERO does not knowingly collect personally identifiable information from children under the age of 13. In the case we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers.

4. Security
We value your trust in using our Game. While no method of transmission over the internet or electronic storage is 100% secure, we utilize industry-standard practices, including Apple's Secure Enclave and cryptographic verification, to safeguard the application.
