LAVNI FTC — Future Time Capsule
TILL THEN.

Some things are worth waiting for.

A letter to the person you will become in ten years.
A photo your child will open on their eighteenth birthday.
A hundred voices gathered for one occasion, sealed until the day they are
meant to be found again.

Lavni sends something forward in time.

Write a message. Add photos, videos or a voice recording. Choose the exact
moment it opens — months, years or decades from now.

Until then, the capsule stays closed.

Not today.
Not by accident.
Not before its time.


HOW IT WORKS

1. Create your capsule
Write what you want the future to read.

2. Add your memories
Photos, videos, voice recordings.

3. Choose the opening date
The exact day and hour it unlocks.

4. Keep it private, or invite others
Share it with the people it belongs to.

5. Seal it, then wait
When the countdown ends, the capsule opens itself.

Till then.


PRIVATE CAPSULES

Something for yourself, or for one person.

A letter to your future self. A message for someone you love. A moment kept
exactly as it is today.

You decide when it opens. Nobody reads it before — not even you, unless you
set a secret code for early access.


COLLABORATIVE CAPSULES

Some moments are better built together.

Invite friends, family, classmates or colleagues with a private link or a QR
code. Each of them adds their own message, photo or video, without creating
an account.

When the contribution window closes, the capsule seals itself. Everyone then
waits for the same morning.

Made for weddings, births and first years, birthdays and graduations, family
archives, class projects, team milestones, and letters to your future self.


DESIGNED TO STAY SEALED

A memory deserves more than a reminder.

Message text, titles and email addresses are encrypted with AES-256 before
they reach our database.

Photos, videos and audio are held in private storage, reachable only through
short-lived signed links.

Every capsule has its own private link, long enough that it cannot be guessed.

Private capsules can carry a secret code for early access. Attempts are
limited, and repeated failures lock it.

Opening dates are enforced on our servers, not on your phone. Changing the
date on a device opens nothing.

Sealed with Lavni means sealed until the day it was meant to come back.


TWO DOCUMENTS, TWO MOMENTS

The invitation card, while a collaborative capsule is still gathering. It
carries the QR code and the short code your guests need, the closing date, and
how many people have already contributed. The day the capsule seals, the card
stops working. Its purpose is complete.

The certificate of sealing, once the capsule is closed. It records the title,
the real date it was sealed, the date it will open, and a reference anyone can
verify at lavni.fr.

The certificate gives no way into the capsule. That is deliberate. It proves
that something exists, that it is sealed, and that its time has not yet come.

Both are A4 PDFs, set in real typography with an engraved frame and a struck
seal. Made to be printed, kept, framed or handed out.


WHAT IS FREE

Simple capsules are free. One message, one recipient, sealed until your date.
No account needed.

Everything else is a one-off purchase. You buy a capsule, not a subscription.
Nothing renews and nothing is charged again.


AVAILABLE IN
English, Français, Español

Today becomes a memory.

Create something now. Leave it untouched. Let time do the rest.

LAVNI F.T.C
TILL THEN.
