Privacy Policy
Last updated: March 1, 2026
1. Overview
ShadowWallet ("we", "our", "us") exists to protect your privacy — not just as a promise, but as an architectural guarantee. This Privacy Policy explains how we handle information when you use ShadowWallet. Because ShadowWallet is a fully client-side, non-custodial wallet, we collect and store no user data whatsoever.
2. Information We Do Not Collect
ShadowWallet does not collect, store, or have access to:
- Your biometric key or private keys
- Your wallet address or balance
- Your transaction history
- Personal identification information (name, email, phone number)
- IP addresses or browser fingerprints
- Cookies or tracking identifiers
3. How ShadowWallet Works
All cryptographic operations, key generation, and transaction signing occur locally in your browser. Your biometric key is generated on your device and is never transmitted to our servers. We have no ability to access, recover, or view your wallet credentials.
4. Blockchain Interactions
When you submit a transaction, it is broadcast directly to the Solana blockchain network. Blockchain transactions are public by nature. ShadowWallet does not operate or control the Solana network and is not responsible for any information publicly visible on the blockchain.
5. Third-Party Services
ShadowWallet may connect to third-party services such as Solana RPC nodes to broadcast transactions and retrieve network data. These services may have their own privacy policies. We recommend reviewing the privacy practices of any third-party services you interact with.
6. Data Security
Because we do not collect or store user data, there is no centralized database of user information that could be breached, subpoenaed, or sold. Your security depends entirely on safeguarding your biometric key. We strongly recommend storing it offline in a secure location.
7. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date. Continued use of ShadowWallet after changes constitutes acceptance of the revised policy.
