Privacy Policy

1. Introduction

Welcome to 999NFT. We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we collect, use, and safeguard your data when you use our decentralized NFT marketplace.

As a decentralized platform built on blockchain technology, 999NFT operates differently from traditional web applications. Most of your interactions occur directly on the Polygon blockchain through your connected wallet.

2. Information We Collect

2.1 On-Chain Data

When you interact with 999NFT smart contracts, the following information is recorded on the Polygon blockchain:

• Your wallet address
• Transaction history (minting, buying, selling, listing NFTs)
• NFT ownership and transfer records
• Smart contract interactions

This information is publicly available on the blockchain and cannot be deleted or modified due to the immutable nature of blockchain technology.

2.2 Off-Chain Data

We may collect the following information through our website:

• Browser type and version
• Device information
• IP address (anonymized)
• Pages visited and time spent on pages
• Referral sources

3. How We Use Your Information

We use the collected information to:

• Provide and maintain our marketplace services
• Display your NFTs, collections, and transaction history
• Facilitate NFT trading and transfers
• Improve user experience and platform functionality
• Detect and prevent fraudulent activities
• Comply with legal obligations
• Communicate important updates about the platform

4. Data Storage and Security

Your wallet and private keys are never stored on our servers. We do not have access to your funds or the ability to initiate transactions on your behalf. You maintain full custody of your assets through your self-custodial wallet.

We implement industry-standard security measures to protect any off-chain data we collect, including:

• Encryption of data in transit using HTTPS/TLS
• Regular security audits and updates
• Access controls and authentication
• Monitoring for suspicious activities

5. Third-Party Services

999NFT integrates with third-party services to provide functionality:

• Wallet Providers: MetaMask, WalletConnect, and other Web3 wallets for blockchain interactions
• IPFS/Arweave: Decentralized storage for NFT metadata and media
• Blockchain RPCs: Polygon network nodes for reading blockchain data

These services have their own privacy policies, and we encourage you to review them.

6. Cookies and Tracking

We use minimal cookies and local storage to:

• Remember your wallet connection preferences
• Store your theme preferences (dark/light mode)
• Analyze website traffic and usage patterns

You can disable cookies in your browser settings, though this may affect some functionality.

7. Your Rights

You have the right to:

• Access any off-chain personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your off-chain data (subject to legal requirements)
• Opt-out of marketing communications
• Withdraw consent for data processing

Note: On-chain data recorded on the blockchain cannot be deleted or modified.

8. Children's Privacy

999NFT is not intended for users under 18 years of age. We do not knowingly collect personal information from children. If you believe we have collected data from a minor, please contact us immediately.

9. International Data Transfers

As a decentralized platform, data may be processed and stored in various locations around the world. Blockchain data is distributed across global nodes. By using 999NFT, you consent to this international data transfer.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by posting the new Privacy Policy on this page and updating the "Last updated" date. Continued use of 999NFT after changes constitutes acceptance of the updated policy.
