Privacy Policy
TL;DR -- Anvil Wallet collects nothing. No accounts, no analytics, no telemetry. Your keys and data stay on your device.
What We Don't Collect
Anvil Wallet does not collect, store, or transmit any personal information. Specifically, we do not collect:
- Names, email addresses, or account identifiers
- IP addresses or device identifiers
- Usage analytics or crash reports
- Private keys, seed phrases, or wallet balances
- Transaction history or blockchain addresses
What Stays on Your Device
All sensitive data is generated, stored, and processed entirely on your device:
- Your seed phrase (BIP-39 mnemonic) -- generated locally, encrypted with AES-256-GCM + Secure Enclave
- Your private keys -- derived from the seed, zeroized from memory after use
- Your wallet configuration and token lists
- Your WalletConnect sessions
None of this data ever leaves your device. There are no servers. There is no "cloud sync."
Network Requests
Anvil Wallet makes network requests solely to interact with public blockchain infrastructure:
- RPC nodes (Ethereum, Solana, Bitcoin, Zcash) -- to fetch balances, broadcast transactions, and query on-chain data
- Price APIs -- to display fiat-equivalent token prices
- Block explorers -- to fetch transaction history
These requests contain only the blockchain addresses and data necessary for the specific operation. No identifying information is attached.
WalletConnect
When you connect to a dApp via WalletConnect, a peer-to-peer encrypted session is established between your device and the dApp. Anvil Wallet facilitates this connection using the Reown (formerly WalletConnect) relay network. Session data is encrypted end-to-end; the relay cannot read your messages.
Third-Party Services
Anvil Wallet does not integrate any third-party analytics, advertising, or tracking SDKs. The only external dependencies are:
- Public blockchain RPC endpoints
- Reown SDK for WalletConnect
- TrustKit for certificate pinning verification
Data Retention
Since we collect no data, there is nothing to retain or delete. If you uninstall Anvil Wallet, all local data (encrypted seed, keys, settings) is removed with it.
Children
Anvil Wallet is not directed at children under 13. We do not knowingly collect information from children.
Changes to This Policy
If we update this policy, we will post the revised version here with an updated date. Given our zero-collection approach, material changes are unlikely.
