Privacy Policy 

 

Last updated: 08.12.2025 

 

This Privacy Policy explains how Xenona (“we”, “our”, “the platform”) collects, uses, and protects information when you access or interact with our Web3 giveaway platform. Because Xenona is built around decentralization, transparency, and minimal data retention, we collect only what is necessary to operate secure, verifiable giveaways. 

 

By using Xenona, you agree to the practices described below. 

 

 

1. What Information We Collect 

 

Xenona is a Web3-native application and does not require email addresses, passwords, or traditional account creation. We only collect information essential for authentication, giveaway interactions, and platform functionality. 

 

1.1 Wallet Information 

 

When you connect your wallet, we process: 

  • Public wallet address
  • Connected network and chain ID
  • Signature used for authentication 

 

This allows us to verify ownership of the wallet and authorize on-chain actions. 

We never access your private keys. 

 

1.2 On-Chain Activity 

 

Because Xenona operates through smart contracts, some information becomes public by default, including: 

  • Giveaway creation actions
  • Prize deposits
  • Participation entries
  • Winner results
  • Transaction details (amounts, sender address, timestamps) 

 

This information is immutable and permanently stored on the relevant blockchain network. 

 

1.3 Optional Profile Data 

 

If you customize your profile, we may store: 

  • Display name
  • Avatar
  • Interface or preference settings 

 

This information is kept off-chain and can be modified or removed by the user. 

 

1.4 Minimal Usage Data 

 

To ensure platform stability, we may collect anonymous technical data such as: 

  • Request logs
  • Error events
  • Device type and browser version
  • Performance metrics 

 

This information is used solely for debugging and improving platform reliability. 

 

 

2. How We Use Your Information 

 

We use collected information only to support essential platform operations. 

 

2.1 Authentication 

 

Your wallet signature verifies that you own the address interacting with Xenona. 

This allows passwordless, decentralized accounts. 

 

2.2 Giveaway Operations 

 

We use your wallet address and on-chain actions to: 

  • Deploy giveaways
  • Validate participation
  • Verify creator-defined rules
  • Determine winners and handle prizes 

 

2.3 Security and Compliance 

 

Some giveaway rules may involve light wallet analysis (e.g., balance checks, address age, simple transactional history) to prevent abuse and enforce eligibility criteria. 

 

2.4 Platform Stability 

 

Anonymous analytics and error logs help us diagnose issues, prevent attacks, and maintain smooth operation. 

 

 

3. What We Do Not Collect 

 

Xenona is designed with strict data minimization in mind. We do not collect: 

  • Emails
  • Phone numbers
  • Passwords
  • Private keys
  • Personal identification documents
  • Off-chain financial information
  • Behavioral tracking across sites
  • Marketing profiles 

 

We do not sell, trade, or share user data with advertisers or third parties for marketing purposes. 

 

 

4. How We Store and Protect Your Data 

 

4.1 Off-Chain Data 

Optional profile information and system logs are stored on secure servers. 

We apply: 

  • Encrypted storage
  • Strict access control
  • Automatic cleanup where applicable 

 

4.2 On-Chain Data 

 

Any data written to a blockchain: 

  • Cannot be altered
  • Cannot be deleted
  • Is publicly visible
  • Is outside our control 

 

This behavior is inherent to blockchain technology. 

 

 

5. Third-Party Services 

 

Xenona interacts with several external systems, including: 

  • Wallet providers (e.g., MetaMask, Trust Wallet, Coinbase Wallet)
  • Blockchain networks (e.g., Ethereum, BNB Chain, Polygon)
  • Third party APIs (e.g., Debank API, Etherscan API) 

 

These systems may process data according to their own privacy policies. 

Xenona does not control or manage data processed by decentralized networks or wallet providers. 

 

 

6. Data Retention 

 

We retain only the minimum off-chain data required for: 

  • Maintaining user profiles
  • Ensuring platform security
  • Diagnosing system issues 

 

Users may request removal of optional profile data. 

On-chain data cannot be removed or modified due to blockchain immutability. 

 

 

7. Your Rights 

 

Depending on your jurisdiction, you may have the right to: 

  • Access off-chain data stored about you
  • Request correction or deletion of off-chain profile information
  • Limit the collection of optional analytics data 

 

These rights apply only to off-chain data. 

On-chain data is permanent and cannot be changed. 

 

 

8. Children’s Privacy 

 

Xenona is not intended for individuals under 18 years of age. 

Users must have the legal capacity to interact with blockchain networks and digital assets. 

 

 

9. Updates to This Policy 

 

We may update this Privacy Policy from time to time to reflect platform improvements or regulatory changes. The “Last updated” date will always indicate the most recent revision. 

 

 

By using Xenona, you acknowledge the decentralized nature of blockchain systems and consent to the handling of information as described in this policy.
