What personal details have to be stored to use NFT Butler?

To place offer requests on your behalf, it's necessary to configure at least one ETH Wallet along with its private key. We highly recommend setting up a new wallet specifically for this use case, containing only a limited amount of WETH to ensure that 1-2 bids can be accepted. Please be assured that the private key will always remain encrypted and securely stored on your client device; it will never be transmitted or stored elsewhere. We strongly emphasize the importance of never sharing your private key outside of the NFT Butler application.
