Cookie Policy
Version 1.0 · Last updated: March 1, 2026
1. What Are Cookies
Cookies are small text files that a website places on your device (computer, smartphone, or tablet) when you visit it. They are widely used to make websites work more efficiently, to provide information to the owners of the site, and to deliver a better user experience. Cookies typically contain a unique identifier and may store information such as your preferences, login status, or session data.
In addition to cookies, we and our service providers may use related technologies that serve similar purposes:
- Local storage — A mechanism that allows websites to store larger amounts of data (e.g., game preferences, theme settings) persistently in your browser. Unlike cookies, local storage data is not automatically sent with every HTTP request and remains until explicitly deleted or until the user clears site data.
- Session storage — Similar to local storage but scoped to a single browser tab or window. Session storage is cleared when the tab or window is closed and is used for temporary data such as in-game state during a session.
- Web beacons (also known as tracking pixels or clear GIFs) — Small, typically transparent images or scripts embedded in web pages or emails that allow us to record when content has been accessed, measure the effectiveness of our communications, and gather usage statistics. Web beacons may be used in conjunction with cookies.
Throughout this Cookie Policy, we use the term "cookies" to refer to cookies and these related technologies collectively, unless otherwise specified.
2. Categories of Cookies We Use

5. Cookies and Mobile Apps
If you access our Service through a dedicated mobile application (rather than a browser), traditional HTTP cookies do not apply in the same way. Mobile apps use different mechanisms for storing data and tracking:
- Device identifiers: Mobile operating systems assign persistent identifiers (e.g., advertising IDs such as IDFA on iOS and GAID on Android) that may be used for analytics and advertising, subject to your device and app permissions.
- Local storage: Apps may store preferences and session data locally on your device using platform-specific storage APIs.
- Firebase Analytics: We may use Firebase (or similar services) for app analytics. Data collection is subject to our Privacy Policy and your consent where required.
- Mobile measurement partners (MMP): We may work with MMPs to measure app installs and attribution from advertising campaigns.
You can typically limit ad tracking in your device settings: on iOS, go to Settings → Privacy → Tracking; on Android, go to Settings → Google → Ads. Please refer to our Privacy Policy for details on how we process data in our mobile applications.
6. Changes to Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in our practices, technologies, legal requirements, or the cookies we use. When we make material changes, we will update the "Last updated" date at the top of this policy and may notify you through the Service or by other reasonable means. We encourage you to periodically review this Cookie Policy.
If we introduce new categories of cookies or materially change how we use existing cookies, we will seek your consent where required by applicable law before applying such changes to your use of the Service. Your continued use of the Service after the effective date of any changes constitutes your acceptance of the revised Cookie Policy, except where additional consent is required by law.
