Overview
Silent Zombie is a mobile game for Android and iOS. The game uses online services to provide player accounts, saved progress, gameplay economy features, friend and trade systems, in-app purchases, purchase validation, and optional analytics.
This policy is not legal advice. It is intended to describe the current data practices for Silent Zombie and will be updated if the game's features, services, or data practices change.
1. Information we collect
The game may collect or process the following categories of information:
- Gameplay content and progress, such as inventory, currency balances, missions, rewards, Battle Pass state, chests, trophies, loadouts, friend codes, trades, and other game state.
- User identifiers, such as a player ID, player name, platform account link identifiers, friend identifiers, or account-level IDs used to operate the game.
- Pending referral and anti-abuse data stored with the invited player's protected game data, such as the literal friend code, a server-issued claim token, opaque binding and credit identifiers, the applicable feature-launch cutoff, account-creation and platform-link evidence, relationship timestamps, and a temporary missing-relationship marker. This pending record does not contain the inviter's player ID and is not placed in an inviter lookup index.
- Qualified referral data, such as invited-player and inviter identifiers, opaque binding and credit identifiers, qualification and application timestamps, status, and qualification route. Only qualified or applied referrals are indexed by inviter; a closed record is scrubbed and unindexed.
- Player safety information and other user content, such as blocked player IDs and reports containing the reporter and reported player IDs, a reason, optional free-form details you submit, report status, and timestamps.
- Network and technical request data, such as IP address, app or browser and operating system information, requested URLs, timestamps, and security logs, processed by online, hosting, domain, and security services that operate the game and website. Approximate or coarse location may be inferred from network information for functionality or security. It is not used for tracking.
- Device or installation identifiers used by platform services, online services, analytics, security, or purchase systems.
- Purchase history and transaction identifiers for in-app purchases, subscriptions, purchase validation, entitlement checks, refunds, renewals, and fraud prevention.
- Product interaction data, such as app launches, gameplay interactions, economy events, purchases granted, feature use, and settings choices.
- Performance and technical diagnostic data collected by analytics where consent applies, such as app and operating system versions, battery level, CPU and GPU type, memory, screen characteristics, and device volume.
- Notification permission status and local notification scheduling information used to remind you about chest timers, where notifications are enabled by you or your device settings.
- Support information that you choose to send by email, such as your email address, device model, operating system version, player ID, screenshots, or a description of the issue.
The game does not require you to provide payment card numbers or bank account details to us. Payment details are handled by the relevant app store payment system.
2. How we use information
We use information for app functionality and analytics, including to:
- Authenticate players and maintain account-linked progress.
- Operate cloud-backed economy, inventory, missions, rewards, Battle Pass, friends, trades, and related gameplay systems.
- Attribute referrals and grant referral-mission progress only when friend-code attribution, a current FRIEND relationship, and qualifying server-verified gameplay activity are all present. Qualifying activity may predate friend acceptance, but no credit is granted before the relationship is current.
- Provide blocking and reporting tools, review alleged abuse, enforce the rules of conduct, and protect players and social features.
- Validate in-app purchases and subscriptions, grant purchased content, prevent duplicate grants, restore entitlements, and detect purchase abuse.
- Understand how players use the game, evaluate features, and improve balance, stability, and usability.
- Send local device notifications about gameplay timers when notification permission is granted.
- Respond to support, privacy, account, and purchase questions.
- Protect the game, online services, and economy systems from misuse, fraud, or technical failure.
Referral missions do not grant progress or rewards merely for downloading the game, registering an account, or leaving a rating or review. Ratings and reviews are never required or rewarded. Referral attribution applies only to qualifying events on or after the activation date configured for the released service and is never retroactive.
The literal friend code, server claim token, pending binding and credit identifiers, cutoff and authentication evidence, relationship timestamps, and missing-relationship marker are retained only while the referral is pending. They are scrubbed when the pending referral is released or closed and after it is promoted to a terminal referral record. A qualified or applied terminal record retains the inviter, invited-player, binding, and unique credit evidence needed for idempotency and fraud prevention. A closed terminal record retains only a minimal invited-player status and reason, without an inviter, binding, credit, or inviter index.
4. Data security
We use reasonable technical and organizational measures designed to protect player data. Network requests to online and platform services use encrypted connections where supported. Access to systems that operate the game is limited to operational use, and purchase validation is checked by online services rather than relying only on the game client.
No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
5. Service providers
Silent Zombie may use service providers and platform services in the following categories:
- Cloud account and game-operation services used for player authentication, saved progress, social features, optional analytics, and online gameplay economy features.
- App store distribution, in-app purchase processing, subscription management, and purchase validation services.
- Analytics services used to understand product interaction and improve the game where analytics consent applies.
- Hosting, security, and infrastructure services used to operate the game, official website, domain, and related online systems.
- Email and support services used to send, receive, and respond to support and privacy messages.
When we share user data with a third party, we require that third party to provide the same or equal protection of user data as described in this Privacy Policy and as required by applicable privacy and platform rules. We share only the information reasonably necessary for the third party to provide its services.
6. Analytics
Silent Zombie includes analytics functionality used to understand product interaction, gameplay economy behavior, performance, and technical diagnostics. Analytics may include events such as feature use, currency changes, chest opening, purchase grants, app and operating system versions, battery level, CPU and GPU type, memory, screen characteristics, device volume, and other gameplay or product interactions.
The game includes an analytics consent control in settings. If analytics consent is not granted, analytics collection is not intentionally started by the game's analytics integration.
7. In-app purchases
Silent Zombie offers consumable diamond packs and a monthly Battle Pass subscription. Purchases are processed by the app store used on your device. We receive purchase-related identifiers and transaction information needed to validate purchases, grant content, prevent duplicate grants, manage subscription access, and handle refunds or revocations.
We do not receive your payment card number, bank account number, or full app store payment credentials.
8. Notifications
Silent Zombie may ask for permission to send device notifications. If you allow notifications, the game may schedule local notifications about chest timers or similar gameplay reminders. You can disable notifications in your device settings.
9. Advertising and tracking
Silent Zombie does not currently include third-party advertising services and does not use collected data for third-party advertising.
We do not use collected gameplay, user ID, device ID, purchase history, product interaction, coarse location, or other user content data for cross-app or third-party advertising tracking, and we do not share that data with data brokers.
10. Support emails
If you contact support or privacy email addresses, we collect the information you choose to include in your message. This may include your email address, player ID, device information, screenshots, videos, purchase details, or issue description.
This website does not currently collect support requests through a web form.
11. Children's privacy
Silent Zombie is not primarily directed to children under 13. Official age ratings vary by country or region and are displayed on the app store listing for your location. If you believe a child has provided personal information through the game or support channels, contact us at the privacy email address below.
12. Data retention and deletion
We retain game, account, purchase, and support information for as long as needed to operate the game, maintain progress and entitlements, provide support, protect against fraud or abuse, comply with platform or legal requirements, and resolve disputes.
Some purchase and entitlement records may need to be retained so that purchases can be validated, restored, or audited.
After account deletion, we retain a one-way suppression marker derived from the former player ID. It does not contain the player ID in readable form and is used only to prevent friend codes, reports, blocks, or other account references from being recreated for an account that no longer exists.
Operational service logs may retain the IP address used for online social features for up to 30 days.
You can delete your Silent Zombie account directly in the game under Settings > Delete account; no email or support request is required. If you no longer have access to the game, you can request deletion by contacting privacy@silentzombiegame.com and including your player ID if available. We may need to retain limited records where necessary for security, fraud prevention, purchase validation, dispute resolution, platform compliance, or legal obligations.
Account deletion instructions are available at https://silentzombiegame.com/account-deletion.html.
13. International processing
Silent Zombie may be available in multiple countries or regions. The services used by the game may process information in countries different from where you live.
14. Your choices
- You can use the in-game settings control for analytics consent where available.
- You can enable or disable notifications through your device settings.
- You can manage app store purchases and subscriptions through your app store account settings.
- You can delete your account directly under Settings > Delete account, or contact us for privacy questions and help with account or data issues.
Some requests may affect your ability to use online features, maintain progress, restore purchases, or access subscription entitlements.
15. Changes to this policy
We may update this policy when Silent Zombie changes, when new services are added, or when data practices change. The updated policy will show a new last updated date.
