I've just published Timelocked (https://github.com/Caltanjun/timelocked), a local app that encrypts any file or message but delays decryption.

One of the main goal is to help with cryptocurrency-related home invasions. The XKCD "$5 wrench attacks" became a reality in France where I live. So it's another way to delay the access of personal funds, but it doesn't need to rely on third parties or multisig. You can just timelock a BIP39 passphrase for a duration of your choice.

It can also help with self-managed inheritance, or digital addictions.
