Questions

What are open-when letters?

A stack of letters, each labelled with a moment: "open when you miss me", "open when you need a laugh". The person saves them and opens each one when that moment comes. They're a favourite for long-distance couples, friends moving away, and kids leaving for college.

Can they open all of them at once?

They can, the same as paper envelopes. Each envelope asks "Is it time?" first, which keeps the magic.

Is it private?

Yes. The letters are encrypted on your device before they're saved, and the key is only in the link you send. We can't read them.

Is it free?

Up to 3 letters is free, with no account or app. For up to 16 letters it's a one-time $3.99.
