Write a letter
It stays on this device and is locked here, before you send it.
0 of 20,000 characters. Put names in the letter if you want them: the capsule has no “from” or “to”.
Photos (optional)
Up to 5. Each is made smaller on this device, and the hidden details a photo carries (such as where it was taken) are removed. A capsule with photos travels as a file, not a link.
Before you lock it
Once it’s locked, nobody can read it before the day, not even you. Keep your own copy of anything you want to remember.
Locking happens on this device. Nothing is sent to us.
What it does
Nobody can open the capsule before its date, not you, not the person you send it to and not us, and on the day anyone with the link or file can.
What it doesn’t do
- It does not keep a copy for you. If you lose the link or the file, nobody can open it, us included.
- It depends on a public time signal run by a group of independent organisations. If they stop running it before the date, the capsule may never open.
- It does not stop the person who wrote the letter telling anyone what it says.
Your letter is locked on your phone or computer before anything is sent. We never see it, and we never ask who you are.
