3. How We Store Your Data
3.1 Local Storage (Your Browser)
Much of your data is stored locally in your browser using localStorage. This includes:
- Encrypted wallet data (if using WorldBridger One Wallet)
- Progress and XP (synced to server when connected)
- Preferences and settings
- Draft content (beats, recordings)
3.2 Server Storage
Our servers (hosted on Vercel/Neon) store:
- User profiles linked to wallet addresses
- Published content (tracks, battle submissions)
- Achievement records and XP totals
- Notification preferences
Encryption: All data in transit uses TLS 1.3. Sensitive data at rest is encrypted using AES-256.
3.3 Decentralized Storage
NFT metadata and permanent content may be stored on:
- Arweave: Permanent, immutable storage
- IPFS: Distributed content-addressed storage
- Solana Blockchain: On-chain NFT data
Note: Data stored on blockchain or Arweave is permanent and cannot be deleted.
4. Blockchain & On-Chain Data
When you interact with blockchain features (minting NFTs, claiming airdrops, voting), some data becomes permanently public:
- Your wallet address and transaction history
- NFT ownership records
- Voting participation in governance
- Smart contract interactions
Important
Blockchain transactions are irreversible and public. Once recorded, this data cannot be deleted or modified by anyone, including WorldBridger One.
5. Third-Party Services
We use the following third-party services:
| Service | Purpose | Data Shared |
|---|---|---|
| Vercel | Hosting & Serverless Functions | Request logs, IP addresses |
| Neon (PostgreSQL) | Database | User profiles, content |
| Solana RPC | Blockchain Interaction | Wallet addresses, transactions |

We do not sell or share your data with advertising networks or data brokers.
