Thank you! Great question. Every wallet is self-custody — keys are generated and stored on the device, never on our servers. Parents have full control over their child's account. You can set it to earn-only mode where kids can only receive sats from you and send them back to you, or give them full self-custody wallet access to manage their own keys when you feel they're ready. You're always in the loop — every chore completion needs your approval before sats move. Would love for you to try it out and give us feedback on how to improve or if there are any features missing that we can add to help make the experience even better — btcbitbybit.com has the iOS/TestFlight and Google/Play Store links. Make sure to use promo code BETA2026B with a Standard subscription to get 100% of your sub value back in sats + get Premium access to Family Corner, which gives you a second parent account plus 5 kids' accounts.
