Write a digital legacy letter to open on a chosen date

Updated

Write a personal letter for someone to read on a future date. Keep it hidden until then.

Postdate shares a message and files through one link that opens at the time you choose. With Basic, Postdate holds the key until then; with Timelock, the key needs a scheduled drand release.

Send it before it opens

A letter in a drawer or folder can be read by anyone who finds it. You may want it read at a particular time in their life.

Set the letter to open on that date. Anyone with the link must wait until then to read it.

Choose a lock

Timelock. Timelock protects access through the link until the scheduled drand release. Original copies you keep remain readable. Choose a date within one year.

Timelock costs $3 USD per Postdate. This covers opening dates within one year and 100 MB including encryption and file packaging. Opening depends on drand and Postdate being available, and on the encryption remaining secure. Senders can keep original copies. Postdates can still expire or be removed for abuse. You see the price before you create the link. Read about Timelock.

Common questions

Is this a substitute for a will?

No. Postdate sets when a personal letter can be read. Postdate does not create or validate a will. Seek legal advice for documents that need legal effect.

What if the person loses the link?

Without the link, the message cannot be recovered. Give it to more than one person, or store it where someone will find it.

What happens after a year?

The opening date must be within one year. Opening is based on that date, not on a death or missed check-in. The link then stays available for the period you chose, up to 30 days. You cannot renew or extend it. If your date is further away, wait until it is within a year.
