Entropy Zero Privacy Policy

Effective August 12, 2026

This policy explains how Entropy Zero handles information when you play the game.

We do not sell your information, and we do not use it for third-party advertising or cross-app tracking.

Information we process

• A randomly generated Firebase anonymous authentication identifier. The game does not require a username.
• Gameplay records such as wins, losses, matches played, selected skin, and owned skins.
• Lobby and multiplayer connection information needed to create and connect to a game server.
• Your IP address may be processed by Firebase, Google Cloud, Edgegap, Apple, and our backend when your device makes network requests. It may be used to select a nearby multiplayer server, establish a connection, maintain service logs, secure the service, prevent abuse or fraud, and investigate technical incidents.
• Apple in-app-purchase receipts and transaction identifiers used to verify, restore, refund, or revoke purchased skins. We do not receive your full payment-card details.
• Technical and diagnostic information that may be generated by the operating system, Firebase, Google Cloud, Edgegap, Apple, or our backend, such as device model, operating-system version, app version, request timestamps, IP address at the time of a request, server and connection events, error messages, and crash or service logs.

Entropy Zero does not currently integrate Firebase Analytics or Firebase Crashlytics. If analytics or crash-reporting tools are added in a future version, this policy and the App Store privacy disclosures will be updated as appropriate.

How information is used

We use this information to provide multiplayer matches, maintain player progress, verify purchases, prevent duplicate or fraudulent transactions, restore content, provide support, secure the service, and diagnose failures.

Legal bases for processing

Where applicable law requires a legal basis, we process information as necessary to perform our contract with you by providing the game and its multiplayer, account, progress, and purchase features. We also process limited information based on our legitimate interests in securing, maintaining, troubleshooting, and improving the service, preventing fraud and abuse, and complying with legal obligations.

Service providers

Entropy Zero uses Apple for distribution and in-app purchases, Google Firebase for authentication, database storage and backend functions, and Edgegap for multiplayer game-server hosting. These providers process information under their own terms and privacy policies.

International transfers

We and our service providers may process or store information in the United States and other countries where we or they operate. Those countries may have data-protection laws that differ from the laws where you live. Where required, appropriate safeguards are used for international transfers.

Retention

Player data is retained while needed to operate the account and meet security, fraud-prevention, accounting, or legal obligations. When you use the in-game deletion option, the game immediately requests deletion of the Firebase account, player profile, and gameplay statistics. Limited information may remain temporarily in service-provider backups or logs until those systems rotate or delete it. Purchase and transaction records may be retained when necessary to validate or restore Apple-owned purchases, prevent duplicate grants or fraud, process refunds, and meet accounting or legal obligations.

Your privacy rights and choices

Depending on where you live, you may have rights to access, correct, or delete your information, receive a copy of certain information, or object to or restrict certain processing. You can exercise deletion through the Skins screen by selecting Delete Account twice, or contact us at the email below for other requests. We may need to verify your request, and some information may be retained where required or permitted by law.

Deleting the current game account removes its Firebase player profile and gameplay statistics. Apple retains its own purchase history. A previously purchased non-consumable skin can be recovered later with Recover Owned Skins while using the purchasing Apple Account.

Data security

We use reasonable technical and organizational measures designed to protect information against unauthorized access, alteration, disclosure, or loss. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Children

Entropy Zero is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information, a parent or guardian may contact us so that we can investigate and delete it as appropriate. This statement should be read together with the age rating shown for the game in your local App Store.

Changes to this policy

We may update this policy as the game, service providers, or legal requirements change. We will post the revised policy with a new effective date. If a change materially affects how we use information, we will provide an additional notice where appropriate, such as an in-game notice.
