- Smart Contract interactions
- Timestamps of transactions
IMPORTANT: Blockchain transactions are permanent, public, and immutable. Anyone can view your transaction history associated with your wallet address. We have no control over blockchain data and cannot delete, modify, or hide this information.
2.4 Information We Do NOT Collect
As a self-custody platform committed to user privacy, we explicitly DO NOT collect:
- Private Keys or Seed Phrases: These are generated and stored only on your device
- Government-Issued IDs: No passports, driver's licenses, or national ID cards

2.5 Public Financial Information on Blockchain
While we do NOT collect traditional detailed financial information (employment, salary, etc.), certain financial data is inherently public and visible on blockchain networks:
2.5.1 Wallet Balances and Net Worth. Your Digital Asset holdings and net worth are publicly visible to anyone who knows your wallet address. Blockchain explorers and analytics tools can calculate and display your total holdings in real-time.
2.5.2 Transaction History and Revenue. All incoming and outgoing transactions are public, allowing anyone to infer your income, spending patterns, and financial activities. This information is permanent and immutable.
2.5.3 Smart Contract Interactions. Your interactions with DeFi protocols, including loans, trades, liquidity provision, and yields earned, are publicly visible.
IMPORTANT: This public financial data exists on the blockchain itself, not in our systems. We do not collect, store, or control this information—it is inherent to how blockchain technology operates. Anyone, including governments, researchers, and analytics firms, can access this data without our involvement or permission.
