There are multiple ways to remove money from your account. From the dashboard, select “Withdraw” and enter the destination Bitcoin address. Funds can also be transferred on Lightning to another Lightning wallet through the Send flow. Additionally, if Lightspark services were to be seriously disrupted or become permanently unavailable, you could use the Funds Recovery Kit (which needs to be correctly set up in the account settings before it can be used). For more details, please see the Fund Recovery Kit page here https://www.lightspark.com/recovery-kit#important-notes.
