1. Information Collection and Use

A. Personal Data

We do **not** collect, store, or share any personally identifiable information (such as your name, email address, phone number, or physical location). The Game does not require any account creation or profile setup to play.

B. Local Data Storage (Shared Preferences)

The Game stores your progress (such as completed level counts, unlocked skins, and settings preferences) locally on your device using Flutter's `shared_preferences` API. This data stays on your device and is not uploaded to our servers.

2. Third-Party Service Providers

To support the free availability of the Game, we integrate third-party advertising services. These third parties may collect and process information about your device in accordance with their privacy policies.

A. Google AdMob (Google Mobile Ads SDK)

The Game uses Google AdMob to display banner, interstitial, and rewarded video advertisements. AdMob may collect and use:

* IP addresses.

* Device identifiers (such as Android Advertising ID / AAID).

* Mobile carrier details.

* Data related to ad views and clicks.

For more information on how Google uses your data, please read the [Google Partner Privacy Policy](https://policies.google.com/technologies/partner-sites) and the [Google AdMob Privacy Policy](https://policies.google.com/privacy).

3. Children's Privacy

Our Game is designed to be family-friendly. We do not knowingly collect personal information from children under the age of 13. Since we do not collect personal data directly from any user, we rely on Google AdMob's standard child-directed settings where applicable.

4. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. You are advised to review this policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
