A slow post office for one

How it works

Write. Open the editor and write freely, answer one guided question at a time, or start from a template such as Gratitude, Goals or Worries I hope are gone. On your own device, drafts save as you type.

Choose a date. Pick six months, one, two, three, five or ten years, or a custom date from one month to 25 years away.

Seal it. Enter your email, check it in large type, and agree to the terms. We seal the letter and send you a receipt right away with the delivery date and a link to cancel.

Receive it. On the day, your letter arrives looking like a letter: your words, the date you wrote them, and a postmark line saying when it was written and delivered. Then you can write back to your next future self.

At events

You might find us at a booth with a tablet, or a QR code you scan with your own phone. You don't need an account. When you're done, the booth screen wipes itself so the next person can't see what you wrote.

How we protect your letters

• Encrypted before it's stored. Letters are encrypted with AES-256-GCM. The key is kept separately from the database.
• Nobody browses letters. Our admin tools only show dates, counts and delivery errors. Event staff see how many letters were written, never what's in them or who wrote them.
• Your account is walled off. The database itself makes sure an account can only reach its own letters.
• Nothing left behind at booths. Booth devices never save drafts. After you submit, or after 90 seconds of inactivity, the screen wipes everything, including the back button's history.
• You stay in control. Every email has a link to cancel the letter or stop all mail from us. If someone used your address, “This wasn't me” cancels the letter and blocks your address from future letters.
• No trackers, no ads. We don't use analytics cookies, and your email is only ever used to deliver your letter.

To be honest about the limits: this isn't end-to-end encryption. To email you the letter, our sending service decrypts it at that moment, and email isn't private once it reaches your inbox. Details are in the Privacy Policy.
