About this app
Write a letter today — leave a gift. Choose the day it may be opened — next year, in ten years, on their 18th birthday. Until that day, no one can read it. Not the person holding it. Not us. No one.
daktilo is an encrypted typewriter. Your letter is encrypted on your phone and turned into a printable origami envelope: the words live as QR codes on paper you fold with your own hands. Our servers never see a single word — there is nothing to hack, nothing to subpoena, nothing to leak.
HOW IT WORKS
• Write your letter and pick the opening date
• It is sealed on your device: the key is locked to a future date using drand, a public randomness network run by independent organizations worldwide
• Print the envelope, fold it, hand it over — or share the capsule digitally
• On the chosen day, the lock simply falls. The letter opens with the code inside the envelope — even if we no longer exist
WHAT MAKES IT DIFFERENT
• Opening early is mathematically impossible — not a policy, mathematics
• No accounts, no tracking, no analytics, no ads
• Every letter carries a verified author stamp (Google sign-in), sealed inside the encryption — no one can write a letter in your name
• The capsule format is an open specification — your letter doesn't even need us
A letter to your newborn for their 18th birthday. A promise to your partner for your tenth wedding anniversary. A few lines for a student to open at graduation. A time capsule for your future self. Some words are worth the wait.
