What Nunchuk is
Nunchuk is a Bitcoin wallet for mobile and desktop focused on multisig, made by Nunchuk Inc. A free plan covers self-managed single-signature and multisig wallets; paid plans add assisted wallets in which Nunchuk holds a platform key that co-signs, cloud backups and inheritance planning. The FAQ says Nunchuk never has enough keys to move funds on its own, that its plans are "unconditionally Non-KYC", and that it collects no personal information beyond email addresses. Whether the app can be used without an email address was not confirmed during this review. No built-in buy or swap feature is described. The apps are published under the GPL-3.0 licence.
