Privacy Policy

Last updated: April 1, 2026

1. Introduction

CoD Zombies Solver ("we," "our," or "the Service") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data when you use our website and progressive web app at codzombiessolver.com.

2. Information We Collect

2.1 Information You Provide

  • Push notification subscriptions: If you opt in to receive push notifications (e.g., when new maps release), we store your push subscription data (endpoint URL and encryption keys) on our servers. This data is used solely to send you notifications and is not linked to your identity.
  • Feedback: If you submit feedback through our feedback form, we may receive the content you provide. Feedback submission may be disabled at times.

2.2 Automatically Collected Information

  • Analytics: We use Vercel Analytics to understand how visitors use our site (e.g., page views, referrers). This may include anonymized or pseudonymized data such as approximate location (country/region) and device type.
  • Feature flags: We use cookies or similar mechanisms to deliver feature experiments (e.g., different navigation layouts). This helps us improve the user experience.
  • Log data: Our hosting provider (Vercel) may collect standard server logs (IP address, request timestamps, user agent) for security and operational purposes.

3. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve the Service
  • Send push notifications you have opted in to receive
  • Analyze usage patterns to improve content and design
  • Respond to feedback and support requests
  • Comply with legal obligations

4. Third-Party Services

We use the following third-party services that may process data:

  • Vercel: Hosting, analytics, and serverless functions. See Vercel's Privacy Policy.
  • Upstash Redis: Storage of push notification subscriptions. Data is stored in a secure database.
  • Google Fonts: Font delivery. Google may collect usage data per their Privacy Policy.

5. Cookies and Local Storage

We may use cookies or similar technologies for feature flags and to remember your preferences. The Service may also use local storage (e.g., for saving solver state on specific map pages). You can control cookies through your browser settings.

6. Data Retention

Push subscription data is retained until you unsubscribe (e.g., by revoking notification permission in your browser). We remove invalid or expired subscriptions when we detect them. Analytics and log data are retained according to our providers' policies.

7. Your Rights and Choices

  • Push notifications: You can disable notifications at any time through your browser or device settings.
  • Cookies: Adjust your browser settings to block or delete cookies.
  • Analytics: You may use browser extensions or settings to limit tracking.

Depending on your location, you may have additional rights (e.g., access, deletion, portability) under applicable privacy laws. Contact us to exercise these rights.

8. Security

We implement reasonable measures to protect your data. However, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security.

9. Children

The Service is not directed at children under 13. We do not knowingly collect personal information from children. If you believe we have collected such information, please contact us.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top will reflect any changes. We encourage you to review this policy periodically.
