Step 01
Write and seal
Choose a recipient, add a title, write your message, and protect it with a password shared outside the app.
Private by design
A quiet place to send messages into the future.
Create a sealed capsule, choose exactly when it should unlock, and give the recipient a message that arrives with intention instead of noise.

How it works
Clear, deliberate, minimal.
The product stays out of the way and keeps the flow easy to follow from start to reveal.
Step 02
Set a release moment
Pick the exact future date and time when the capsule should become available.
Step 03
Reveal with intent
At release, the recipient opens the capsule and decrypts it with the password you already shared.
No password storage
The app never stores the decryption password, so sharing it stays fully in your control.
Time aware delivery
Capsules remain unavailable until the scheduled release moment has passed. Even you cannot read it early.
Clean dashboard
Available, pending, and sent capsules are separated so every state is immediately understandable.
Multiple recipients
Send the same capsule to a group — great for team farewells, family letters, and milestone announcements.
Open receipts
Get notified by email the moment a recipient decrypts your capsule. Close the loop without having to ask.
Encrypted files
Attach photos, PDFs, or any file. Everything is encrypted with the same password before upload — nothing leaves unprotected.
Use cases
Made for moments that matter.
People use When You Open Me for the messages they can't send today but need to send eventually.
Proposals and anniversaries
Write a letter to your partner that opens on your first anniversary, a proposal date, or the day they finish something hard.
Graduation messages
Seal advice or a memory for a student and schedule it to open on graduation day — even if you can't be there in person.
Team goodbyes
Leaving a job? Write a farewell to the team and schedule it to arrive on your last day. No awkward "reply all" required.
Letters to your kids
Capture something true about this moment and schedule it to open when they turn 18, graduate, or start a family of their own.
Goals and commitments
Write a letter to yourself at the start of a challenge. Schedule it to open when the deadline arrives and check whether you did it.
Long-distance relationships
Schedule daily or weekly messages during a long separation. Each one arrives at the right moment, not as a batch download.
Create your first capsule in a minute.
