This Privacy Policy explains how Nurhaini (“Nurhaini,” “we,” “us,” or “our”) handles information when you use the Android game Powder Rush, package name com.powderrush.snowbrawl (the “Game”).
Privacy contact: nurhainiloteng@proton.me
Country of legal jurisdiction: Indonesia
1. Summary
Powder Rush uses a compatible Solana wallet to authenticate you before gameplay. The current version has no Nurhaini-operated user-account server, advertising SDK, analytics service, cloud-save service, or developer-operated transaction service. Wallet verification occurs on your device, and the Game does not request your private key or seed phrase.
2. Information We Process
A. Wallet authentication information
When you choose to connect a wallet, the Game processes:
- your public Solana wallet address;
- the Sign-In With Solana message, including the Game domain, statement, one-time nonce, issue time, and expiration time;
- the signature returned by your wallet; and
- a temporary wallet authorization token and connection status.
This information is used to verify on your device that you control the presented public address and to unlock gameplay. The signature verification result is not a financial transaction. The Game does not request or receive your seed phrase, private key, wallet password, token balance, financial-account credentials, government identification, biometric data, precise location, contacts, photographs, microphone recordings, or camera data.
The Game keeps the wallet authorization token in process memory only. It is not intentionally written by the Game to persistent storage and is discarded when the Game process closes. The Mobile Wallet Adapter SDK or Android may locally remember the package name of the wallet you selected so that the same wallet can be offered on a later connection.
B. Gameplay and technical information
The Game processes gameplay state in device memory, such as health, scores, course progress, selected items, control input, and computer-controlled opponent state. The current version does not upload this gameplay state to a Nurhaini-operated server or provide cloud saves.
The Unity runtime and Android may create local technical logs or diagnostic information, such as device model, operating-system version, shortened wallet-address output, wallet connection status, or error messages. Nurhaini does not integrate Unity Analytics, Unity Ads, Unity Cloud Diagnostics, Firebase Analytics, or another remote analytics or crash-reporting service in the current version.
C. Information you voluntarily send
If you email us, we receive the information you include, such as your email address, message, and attachments. Please do not send a seed phrase, private key, wallet password, government identification, payment-card data, health information, or other sensitive information.
3. Android Permissions
The current APK requests only these user-facing system capabilities:
- Internet: used for compatible wallet and Solana connectivity.
- Vibration: used for gameplay haptic feedback.
The Game does not request camera, microphone, contacts, precise location, SMS, phone, storage-library, or advertising-ID permission.
4. How We Use Information
We use information only as reasonably necessary to:
- authenticate your wallet connection and unlock the Game;
- operate gameplay and local controls;
- maintain security, prevent abuse, and diagnose errors;
- respond to support, privacy, or legal requests;
- comply with applicable law and enforce the Terms of Use; and
- improve the Game using feedback you voluntarily provide.
Depending on the law that applies, the legal basis may be your consent, performance of our agreement with you, our legitimate interests in operating and securing the Game, or compliance with legal obligations. You may decline the wallet request, but the current version cannot enter gameplay without successful wallet verification.
We do not sell personal information. We do not use wallet information for targeted advertising, credit decisions, biometric identification, or unrelated marketing.
5. When Information May Be Shared
We do not transmit wallet authentication data to a Nurhaini-operated backend. Information may nevertheless be processed by or disclosed to:
- Your chosen wallet provider and Mobile Wallet Adapter components, which handle the wallet authorization interface and are governed by the wallet provider’s own terms and privacy policy.
- Android, your device manufacturer, and operating-system services, which operate app launching, local communication, permissions, storage, and diagnostic logs.
- Solana Mobile and the Solana dApp Store, which distribute the Game and process store-related information under their own privacy practices. Solana Mobile’s dApp Store privacy policy is available at docs.solanamobile.com/dapp-store/privacy-policy.
- Professional advisers, authorities, or other recipients required by law, where reasonably necessary to comply with legal process, protect rights or safety, investigate fraud or security incidents, or complete a lawful transfer of the Game.
We require any service provider engaged directly by us to protect applicable user information and use it only for authorized purposes. Third-party wallet providers and store or operating-system providers act under their own policies where they independently determine their processing.
6. Public Blockchains
A Solana public address and its existing on-chain activity may be publicly visible and may be copied or analyzed by anyone independently of Powder Rush. The current version uses a wallet signature for authentication only and does not initiate an on-chain transaction or publish the sign-in message to the Solana blockchain.
We cannot delete or change information that was independently written to a public blockchain by you, your wallet, or another party.
7. Storage and Retention
- Wallet address, signed message, signature, and authorization token are processed in memory for the active Game process and are not intentionally retained by Nurhaini after the process closes.
- A selected-wallet preference may remain locally on your device until you clear the Game’s storage or uninstall it.
- Gameplay session data remains local and may be reset when the Game closes, is updated, has its storage cleared, or is uninstalled.
- Support emails are retained only as long as reasonably necessary to answer the request, maintain a support record, protect legal rights, or comply with law, and are then deleted or anonymized where reasonably practicable.
8. Your Choices and Rights
You may:
- decline or cancel a wallet request;
- revoke Powder Rush authorization in your wallet, if supported by that wallet;
- clear the Game’s local data through Android Settings → Apps → Powder Rush → Storage → Clear storage;
- uninstall the Game; and
- email nurhainiloteng@proton.me to request access, correction, deletion, restriction, objection, withdrawal of consent, or a copy of personal information that Nurhaini controls.
Powder Rush does not create a server-side user account. Clearing app storage/uninstalling deletes Game-controlled local data; revoking authorization addresses wallet-side authorization. If you request deletion by email and we hold no server-side data about you, we will tell you. We may ask for information reasonably necessary to verify and complete a request and may retain information where required by law, security, fraud prevention, or legal claims.
You may also have the right to complain to a competent data-protection or consumer authority under applicable law.
9. Security
The Game verifies Sign-In With Solana signatures locally, uses a short-lived nonce and expiration time, and keeps its wallet authorization token in memory rather than Android plaintext preferences. No method of electronic processing is completely secure, and we cannot guarantee absolute security of your device, wallet, Android, network, or third-party services.
Never provide your seed phrase or private key to Nurhaini. A legitimate Powder Rush support response will not ask for it.
10. International Processing
Your wallet provider, Android services, Solana Mobile, email provider, or other third-party services may process information in countries outside your own. Their processing is governed by their respective policies and applicable law. Where Nurhaini transfers personal information internationally, we will use safeguards required by applicable law.
11. Children
The Game is intended only for people aged 18 or older. We do not knowingly collect personal information from anyone under 18. If you believe a person under 18 has provided information to Nurhaini, contact nurhainiloteng@proton.me so we can investigate and delete it where required.
12. Changes to This Policy
We may update this Privacy Policy to reflect changes to the Game, law, or data practices. We will update the effective date and provide additional notice or obtain consent where applicable law requires it. Material new data collection will be disclosed before or when it begins.
