Nunchuk does not collect any personal information beyond email addresses. You can delete your account data at any time by navigating to ‘Account Settings > Delete Account’ inside the app. We have also gone out of our way to build many privacy-enhancing tools, such as end-to-end-encrypted messaging, Primary Key accounts, and an inheritance plan that does not rely on proof of identity.

Nunchuk is Bitcoin-only. Our singular focus on Bitcoin is the reason we are able to set the highest of standards for Bitcoin custody.

You can create hot keys on your phone with the Free plan. However, there are no hot keys on your phone if you use an assisted personal multisig wallet via one of our paid plans. With an assisted personal multisig wallet, all of your keys are cold, while your phone functions as a watch-only interface and does not have any signing privileges. This design makes your wallet much safer and allows you to change phone without ever worrying about losing access to your funds.
