Privacy Policy

Nightfall - Undead Survivor

Last updated: August 3, 2026

This policy explains how Nightfall ("the App"), published by Eduard Bruch, handles information when you play, use cloud save or leaderboards, view ads, sign in with Apple or Google, or make a purchase.

2. Information the App Processes

• Game progress and cloud saves: inventory, currency, unlocks, settings, and progress are stored on your device and backed up using a randomly generated player ID. On iPhone and iPad, Apple iCloud key-value storage may also hold a copy, and the player ID is kept in the Keychain. On Android, the player ID is kept with Google Block Store and Android backup so a reinstall can find your save.
• Leaderboards: your chosen player name, score, title, and pseudonymous player ID are sent when you use leaderboard features.
• Optional Sign in with Apple or Google: if you choose account backup, the App receives the provider's stable user identifier. It does not request your name or email address.
• Purchases: Apple (App Store) or Google (Google Play) processes payment. RevenueCat receives purchase receipts, transaction information, product IDs, and a pseudonymous app-user ID to unlock and restore purchases. Our server stores transaction IDs with your player ID so a purchase is delivered exactly once across your devices.
• Advertising: Google AdMob may process device and advertising identifiers, IP address, approximate location derived from IP, ad interactions, and diagnostics. Tracking or personalized advertising is used only where you have given the required consent.

3. Purposes and Legal Bases

• Provide gameplay, saves, leaderboards, purchases, and restoration: performance of the service or contract (GDPR Art. 6(1)(b)).
• Prevent fraud, protect purchases, and secure online features: legitimate interests (GDPR Art. 6(1)(f)).
• Personalized advertising and tracking, where offered: consent (GDPR Art. 6(1)(a)). You can refuse tracking without losing access to the game.

4. Service Providers

The App uses the following processors:

• Apple for App Store payments, iCloud, and optional Sign in with Apple
• Google for Google Play payments, Android backup, and optional Sign in with Google
• RevenueCat for purchase management
• Google AdMob for advertising, with AppLovin and Unity Ads as additional ad networks through AdMob mediation
• Cloudflare for cloud saves and leaderboards

We do not sell your personal information. Providers may process data outside the EU/EEA using legally recognized transfer safeguards.

5. Advertising Choices

On iOS, the App asks for permission before allowing cross-app tracking. You can change this later in iOS Settings → Privacy & Security → Tracking. On Android, you can reset or delete your advertising ID in Settings → Privacy → Ads (or Settings → Google → Ads). Where required, the App also presents Google's consent choices and a way to revisit them. Refusing consent may result in non-personalized or limited ads.

6. Retention and Deletion

Local data remains until you delete the App or clear its data. Cloud save, leaderboard, account-link, and purchase records are retained while needed to operate and secure those features, meet legal obligations, and preserve purchased currency and entitlements. To request deletion of server-side data, email support with your Nightfall player name and, if available, your player ID. Some transaction records may need to be retained for legal or fraud-prevention purposes.

7. Your Rights

Depending on where you live, you may request access, correction, deletion, restriction, portability, or objection, and withdraw consent at any time. Contact support@eduardbruch.com. EU/EEA users may also complain to their local supervisory authority, including the Hamburg Commissioner for Data Protection and Freedom of Information.

8. Children

Nightfall is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided information, contact us so we can delete it.

9. Changes

We may update this policy when the App, its providers, or legal requirements change. The latest version will remain available here.
