A private time capsule for your child

A lifetime of little moments,
beautifully kept.

Give your child their own phone number and email address. Family text it photos and voice notes, email it letters, or simply call it and leave a voicemail. It all waits in one private vault until their 18th birthday. No app. If Grandma can send a text, she can add to it.

The gift is the time you take to keep it.

From: MomOctober 7, 2026
Dear Julius,

Today you asked me why the sky is blue. I didn't know, so we looked it up together on the kitchen floor. You were six, and you wanted to know everything.

I hope you never stop asking.

All my love,
Mom

What you can save

The moments they'll treasure.

The stories, voices and small details that are too meaningful to leave scattered across everyone's camera rolls. Each one can be sent the way your family already shares.

Photos
Moments big and small, with the story of the day attached.
Text or email it, full quality, dated automatically
Letters
Hopes, advice and love, written to the adult they'll become.
Email or text it. Start with SEAL to keep it private
Voice notes
So they can hear your voice, always. Laughs included.
Send a voice memo, or call his number and leave a voicemail
Milestones
First steps, first words, first day. Dated and kept in order.
Text "Milestone: first tooth", kept with the date and time
No app required

If Grandma can send a text, she can add to it.

Julius gets his own phone number and email address. Anyone you invite sends to it the same way they already share with family. Grandpa can call it on a birthday and just talk. Each memory lands in his vault, dated and in order.

01
Call, text or email. Call (236) 233-2718 to leave a birthday message, or text it photos, voice notes and videos. Letters go to julius@dear18.com.
02
We reply to confirm it's in Julius's vault, transcribed and stamped with the date and time. Parents get a weekly digest.
03
Start with SEAL and it stays sealed. Not even Mom and Dad can read it before Julius does.

How dear18 works
01
Set up your child's vault

Add your child and their birthday. They get their own number and email address.

02
Invite your family

Add family by phone or email, or share a link. We text each of them a contact card to save. From then on they just call, text or email it.

03
Gift it at 18

On their birthday they get the key by email, and a keepsake card for you to hand over in person.

The reveal

On September 2, 2038, it all opens at once.

Julius gets an email with his key, and you get a keepsake card to put in his hands. He opens eighteen years of voices, letters and photos, sealed ones included, in the order they happened.

Private by design

Only for them. Until they're 18.

Your family's memories are not a product. We never sell, share, analyse or train on them. Not for ads, not for AI, not for anyone. That is the whole point of not being a social network.

Never monetised
Your photos, voices and letters are never sold, shared with partners, used for advertising, or fed to machine learning. Ever.
Never public
No profiles, no followers, nothing shared. One vault, one family.
You approve senders
Texts from an unknown number wait for you to approve them first.
Sealed means sealed
Whoever sends a note decides whether parents can read it before Julius does.
Yours to download
Every memory, original quality, at any time. Leave whenever you like and take it all with you.
From early families
"My mother has never downloaded an app in her life. She's sent forty photos this month."
Priya, mom of two
"I write to her once a month by email. It's the most important thing I do."
Marcus, dad of one
"Grandpa left a voicemail for his 18th birthday. I haven't heard it. That's the point."
Elena, mom of three
Questions

Asked by parents, answered plainly.

No. She texts photos, notes or voice memos to Julius's number, the same way she texts you. Email works too. We reply to confirm each one arrived.
