BTCapsule is a Bitcoin Time Capsule for your private keys. Enter a year and your private keys, and when the year arrives, your private keys will be available to whoever you give the program to. This is perfect for inheritance of Bitcoin, very easy to use, and allows you full access to your Bitcoin.
Good project, but the only way for me to use something like this, is to give a certain type of hint
[as opposed to entering my private key] that could "only" mean something to a specific person, and judging by the screenshots on your website, looks like it can be used for such a thing.
