Privacy Policy

Last updated: 2025-09-25

Overview

This game is a Progressive Web App (PWA) that runs entirely in your browser/device. We do not operate any backend servers for the game and we do not collect, store, or process any personal information on our servers.

No Personal Data Collection

We do not collect or require any of the following:

• Account creation or sign-in
• Names, email addresses, phone numbers, or contact details
• Analytics, telemetry, or usage tracking
• Advertising IDs or user profiling
• Precise location data
• Tracking cookies

On-Device Storage Only

To enable gameplay features (e.g., remembering your settings or progress, enabling offline play), the game may store small amounts of data locally on your device using technologies such as localStorage, IndexedDB, or Cache Storage. Examples include:

• Audio, language, or control preferences
• Game progress and last played level
• Cached images, audio, or other static assets for offline use

This data never leaves your device and is not transmitted to our servers because we do not have any. You can delete this data at any time via your browser’s site data settings (for example: clear “Site data” or “Cookies and other site data” for this site).

Network Requests and Caching

The app may request static game assets (such as images, audio, or fonts) from the hosting domain to load or update content. These requests do not include personal data.

If a service worker is used for offline support, it only caches assets and data necessary for gameplay. Clearing your browser cache or site data will remove this cached content.

No Cookies, Tracking, or Ads

• No tracking cookies
• No analytics or telemetry
• No third-party advertising
• No push notifications or background sync

Third-Party Services and Hosting Logs

We do not integrate third-party SDKs or analytics. The game may be hosted by a third-party static hosting provider. Such providers may collect standard server logs (e.g., IP address, browser type) for security and operational purposes. We do not access, control, or combine any such logs with other information.

The game may contain optional links to external websites (for example, documentation or source code). Those sites are governed by their own privacy policies.

Children’s Privacy

This game is suitable for a general audience and is designed without personal data collection. We do not knowingly collect personal information from children. If you believe we have inadvertently collected such information, please contact us and we will delete it promptly.

Security

Because gameplay data remains on your device and we do not store any user data on servers, privacy risks are minimized. We recommend keeping your device, operating system, and browser up to date and protected.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date.
