How it works

Three steps. One small ritual.

Write something worth keeping. Choose when it should be read. Decide who, if anyone, gets to read it.

STEP 01

Create

Write a private note — a letter, a secret, account details, a memory — and choose when it unlocks.

STEP 02

Lock

Set an unlock date or choose an inactivity period (30 days to 5 years). Your content is encrypted and hidden until the condition is met.

STEP 03

Share (optional)

Keep it private, or share with a trusted group. Recipients see your custom message while they wait, and get notified the moment it opens.

Two unlock modes

Choose when it opens.
Or what makes it open.

Two ways to seal a TimeCapsule, for two different kinds of patience.

Date-based unlock

A specific moment
on the calendar.

365d 12h 42m 07s
UNLOCKS · MAY 2, 2027 · 09:00
  • Pick a specific date and time
  • Live countdown — down to seconds in the final 24 hours
Perfect for: birthdays, anniversaries, future-self messages, scheduled reveals.
Inactivity-based unlock

Opens if you
fall silent.

IF NO ACTIVITY FOR
30d 90d 6mo 1y 2y 5y
  • Capsule opens if you stop using the app for the chosen period
  • Activity is tracked automatically — nothing extra to remember
Perfect for: digital legacy, emergency information for family, "if something happens to me" scenarios.
Sharing & safety

Built for peace of mind.

Whatever you write stays unreadable to everyone — including us — until the moment you chose.

End-to-end encrypted

Only you and your chosen recipients can ever read the content. We don't have the key. We can't make one.

Recipient message

Show a personal note while the capsule waits — "You'll understand when the time comes." A small kindness for the wait.

Local backup for recipients

Recipients automatically get a sealed local copy that survives even if the shared group is removed or the owner's account is terminated.

Notification alerts

Recipients get a gentle notification the moment a capsule unlocks — wherever they are, on whichever Apple device is closest.

The unlock

The moment arrives.
The capsule opens.
The message is yours.

A small celebration when a TimeCapsule comes due — for the writer, the reader, or both.

Ideas to start with

What will you
seal away?

A few things people are putting in their first TimeCapsule.

Future self

Write a letter to yourself one year from now. Predictions, hopes, the questions you're sitting with.

Family safety

Store important account details that unlock if you're inactive for six months. Your family will know what to do.

If inactive · 6 months

Celebrations

Schedule a birthday or anniversary message for someone special — and forget you ever wrote it.

Legacy

Leave messages for the people you love, protected until the right time. They'll hear from you when it matters.
