Inputs are processed in your browser. Our application does not transmit tool inputs, wallet addresses, quiz answers or progress to a server. Do not enter secret keys or recovery phrases; these tools never need them.
Progress lives on your device
Completed lessons use localStorage in this browser. You can erase that record below or clear this site’s browser storage. Private browsing or browser restrictions can prevent progress from being saved; the lessons remain usable.
