Posthumous Letters: Could They Uncover Truths in Cases Like Madeleine McCann?

Based on what the homepage says, it seems you're handling this by allowing the recipient to get the decryption keys right away, and then also your system will handle the 3-day period. Is that correct?

If so, your entire promise about it being inaccessible to law enforcement falls apart. Law enforcement will demand the encrypted data, and then the person who received the message will likely hand over the decryption key, and that's all they need. Something to keep in mind when making these promises to customers.

I think you should also lean way more into the "final farewell" aspect of it — not necessarily a love letter, but a nice "Goodbye, everybody" message, and focus on how a platform like this can be useful to send personal information, like passwords, to recipients who may need them after you're gone. Everybody is going to die, so you have a huge market, here.

In contrast, focusing on "this is great for serial killers" is very grim, and I don't think any serial killer is going to want to hand over their credit card information and associate that to correspondence they send to the victim of the family. It's also a bit tasteless to use an active missing person case (Madeleine McCann) when promoting your project to potential other criminals.

Hey guys I developed Cronos! A website where you can send encrypted messages and then they only can be opened if you let or if you die! If someone tries to open your message you receive a warning and you have 3 days to destroy it! In this way serial killers can tell their story after dead and become a netflix documentary! Or your lover can let you a letter for eternity!

Maybe you the next netflix documentary!
