Privacy Policy

Last updated: June 1, 2026

CartoGenius is developed and operated by K2 Development ("we," "us," or "our"). This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data.

1. Information We Collect

Information You Provide

• Player name — the name you enter on the start screen. This is displayed on the global leaderboard.

Information Collected Automatically

Game data
Your scores, selected category, difficulty level, and game timestamps. This data is stored in our database and displayed on the global leaderboard.

Anonymous user identifier
When you first open CartoGenius, we automatically assign you an anonymous user ID via Firebase Authentication. This ID is used to associate your scores with your account without requiring you to register or log in. It is not linked to your name, email, or any other personal identifier unless you choose to Sign in with Apple.

Device and usage data
Firebase may collect basic device information (device type, operating system version) and app usage data to support app functionality and stability. This data is governed by Google's Privacy Policy.

Information Collected If You Sign in with Apple

• We receive your name and, optionally, your email address from Apple.
• Your Apple ID credential is used to link your anonymous account to a permanent account, preserving your game history and leaderboard scores across devices.
• Your email address (if provided) is stored by Firebase Authentication and is not shared with third parties or used for marketing.

Subscription Information

• Payment processing is handled entirely by Apple. We do not collect or store your payment card details.
• RevenueCat, our subscription management provider, receives a subscription receipt and anonymous user ID to verify and manage your entitlement.

2. How We Use Your Information

• Display your scores on the global leaderboard
• Track your game history and personal bests
• Verify your CartoGenius Pro subscription status
• Maintain your account across sessions and devices
• Improve app performance and fix bugs

We do not use your information for advertising, and we do not sell your data to third parties.

3. Data Sharing

We share data only with the following service providers, solely to operate the app:

Provider	Purpose	Privacy Policy
Google Firebase	Authentication, leaderboard database	firebase.google.com/support/privacy
RevenueCat	Subscription management	revenuecat.com/privacy
Apple	Payment processing, Sign in with Apple	apple.com/privacy

We do not share your data with advertisers, data brokers, or any other third parties.

4. Data Retention

• Leaderboard scores are retained indefinitely to maintain the integrity of the global leaderboard.
• Anonymous user accounts persist until you delete the app or request deletion.
• Sign in with Apple accounts persist until you request deletion.

To request deletion of your data, contact us at privacy@k2dev.xyz. We will delete your account and associated scores within 30 days.

5. Children's Privacy

CartoGenius is rated 4+ and is suitable for all ages. We do not knowingly collect personal information from children under 13. The only personal information we collect is a player name chosen by the user — we recommend parents choose an appropriate name for younger players. If you believe a child has provided personal information, please contact us at privacy@k2dev.xyz.

6. Your Choices

• Player name — you can change your player name at any time on the start screen.
• Leaderboard — if you wish to have your scores removed, contact us at privacy@k2dev.xyz.
• Sign in with Apple — signing in is optional. You can use CartoGenius fully with anonymous authentication.
• Subscription — you can cancel CartoGenius Pro at any time through Settings → Apple ID → Subscriptions.
• Data deletion — you may request full deletion of your account and data by contacting privacy@k2dev.xyz.

7. Security

We use Firebase's security infrastructure to store your data. Firestore security rules restrict access so that user data can only be read or written by authenticated sessions. We do not store payment information.

8. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
