## Notice

1. Surf does **NOT** store any of your third-party login information.
2. Surf is a non-custodial wallet and does **NOT** in any way store or retrieve mnemonics/private keys. This is because Surf Wallet uses [zkLogin](/security/about-zklogin.md), where mnemonics and private keys do not exist. [learn more](/security/about-zklogin.md)
3. Logging in with the same third-party account on a different platform will result in different blockchain addresses (For example, using the same Google account to log in to Surf Wallet on iOS and Surf Wallet on Android will yield different addresses, which means different wallet treasuries).
