How a digital time capsule works.
Eonro does one thing, carefully: it holds what you give it sealed and hidden until a date you choose, then opens it on its own and lets the people you picked know. No reminders, no early peeks, nothing to keep checking. Here is exactly what happens, start to finish.
- 01
Write your message and add files
Start a capsule with a written message — a letter to your future self, a note for someone you love, a record of where things stand today. Then attach files: photographs at full resolution, scans of handwritten letters, voice memos with the room noise still in them. Everything is stored exactly as you leave it and comes back in the same form.
- 02
Choose the unlock date
Pick any future moment — from a few hours away to a hundred years from now. The date is the whole contract: it is when, and the only when, the capsule opens. On the free plan you can seal up to five years ahead; paid tiers extend that to thirty or a hundred years.
- 03
Seal it — and it is sealed for good
Sealing is the point of no return. The moment you seal, nothing can be changed, added, or removed, and the contents disappear from view. There is no early peek and no way to rush it — not for you, not for anyone. That permanence is exactly what makes a capsule worth trusting.
- 04
We hold it sealed while the clock runs
Once sealed, the capsule sits locked with a live countdown. The message and files stay hidden the entire time. You do not have to set a reminder, check in, or keep an account active — the date does the remembering for you.
- 05
It opens automatically and everyone is notified
On the unlock date the capsule opens by itself — no action needed. Everyone you listed as a recipient receives a plain email with a link to view it. No marketing, no spoilers, no reminders to set. From that moment the contents are visible again and every file can be downloaded in its original form.
What you can put inside
Proof it is genuinely from now
Every capsule is timestamped on the day it is sealed. Years later, whoever opens it can see it was created when it claims to be — that the letter, the photograph, the promise really did come from the moment you sealed it, not from some edit made along the way. Because sealing is irreversible, that timestamp is something you can trust.
