From LN.Tips:

🏛 Terms

We are not custodian of your funds. We will act in your best interest but we're also aware that the situation without KYC is tricky until we figure something out. Any amount you load onto your wallet will be considered a donation. Do not give us all your money. Be aware that this bot is in beta development. Use at your own risk.

I wouldn’t keep a substantial amount on it but all the self custodial options are not great for smol zaps.
