Dear Anna,
for the day you turn 18

The morning you were born, the whole world went quiet. I want you to remember where you came from — and how loved you are, from the very first second…

— Mum
SEALED · 30 MAY 2026
You'll forget what they said yesterday.
We won't.

The first words. The first laugh. The first time they fell asleep on your chest. You promise yourself you'll remember — and you will, for a few years. Then the years stack up, and the early ones blur. Nestori is the place where you write it down before it fades.

Everything that matters, kept forever

From the first movements in the womb to the first steps — every moment safe.

From the first letter to the 18th birthday

Four steps — with letters for any birthday along the way. Then it just runs in the background of life.

STEP 01
Write the first letter
Today, in two minutes. The first letter your child opens at 18. You'll come back to it — starting is what matters.
STEP 02
Add memories along the way
Photos, videos, voice notes from a normal Tuesday. The small things you swear you'll remember and won't.
STEP 03
Invite the people who love them
Grandparents leave stories. The other parent adds their voice. The capsule fills with the family they came from.
STEP 04
Letters unlock on the birthdays you choose
Each letter arrives on the birthday you set — any age up to 18. The 18-year capsule opens last — everything you ever saved, in their hands.

Why Nestori exists

I go through my parents' photo albums more often than I admit. Every time, I'm looking for the same thing: to turn a photo over and find something written on the back. The place. The year. One sentence.

A few have it. Most have nothing.

There are landscapes without people and people without context. A long table, faces I can't all name any more. I don't know what they were celebrating. I don't know who took the picture.

I ask my parents and they usually remember — roughly. "That was the summer when…" They look at each other, correct each other, settle on a version. And that version is what stays. Not because they're lying, but because that's what memory does after thirty years: it rounds off, it gets negotiated, it thins out until only the outline is left.

The small details are gone. What I used to say. What made me cry. What an ordinary Tuesday looked like.

My childhood exists, but as their story, not as my memory. And I'm lucky — I still have someone to ask. Not everyone does.

Someone close to me once told me they'd set up an email address in their child's name. They sent photos there, little videos, things they wanted the child to see later. I thought it was a good idea.

I asked them about it a while afterwards. They'd stopped. Not because they'd stopped caring — it had simply faded, the way things fade when they take effort and have nowhere to live.

So I started asking other parents. The same pattern everywhere. Either they dump the whole camera roll into a folder nobody opens again, or they start well and stop after two or three years.

And the ones with more than one child all said the same thing: for the first, they did everything. When the second arrived, there wasn't time. And at some point, not for the first either.

Nobody misses this for lack of love. They miss it for lack of anywhere to put it.

I'm not a parent yet.

When I am, I want to be able to write two lines about what happened today and know they won't be lost. I want my child, twenty years from now, not to depend on how well I remember.

I built Nestori for myself — for the parent I'll be. That other parents are already using it is the part I didn't expect.

You can start today too. The first letter takes two minutes.

Frequently asked

Everything you need to know before you start.

What if Nestori doesn't exist when my child turns 18?
We commit to 180 days notice and a full ZIP export of everything you saved — photos, videos, letters, everything. You also have a one-click export any time from your profile. Your memories are never locked in.
Can the child see their capsule before 18?
No — capsule content stays sealed until the age you set (any age up to 18). You decide which memories go in the time capsule vs. the regular timeline that family can enjoy together now.
Who can see my memories?
Only you and the family members you invite. Data is encrypted at rest. We never train AI on your content.
What devices are supported?
Web, iOS and Android (Android coming soon). Auto-sync across all. Start on your phone during a coffee break, continue on the laptop in the evening.
Can I change my plan later?
Yes, any time. Upgrade or downgrade from your profile. The difference is prorated.
How do subscriptions work?
Free — 1 child, up to 20 memories and 5 GB. Good for trying us out.

Nestori 18 — 1 child, unlimited memories, 100 GB storage, video, sealed letters for the 18th birthday, plus 2 family members you can invite (e.g. both parents).

Nestori Family — unlimited children, unlimited storage, unlimited family members (grandparents, aunts, godparents…). For households with more than one kid or a larger circle.

All plans start with 1 free month. Cancel anytime from your profile.
How do family invitations work?
You invite someone (grandparents, aunts, partner) by email. They get a link, create a free account, and gain access to your child's capsule.

They can be a contributor (adds memories and reactions) or a viewer (read only). You control the role at any time and can revoke access.

Invited people can have their own subscription and their own children — accounts are independent. An invitation grants access; it doesn't transfer your plan.

Memories added by family members count toward your storage, not theirs. Sealed messages (letters for 18) stay invisible to them until delivery.
Can I leave a family I've been invited to?
Yes — Profile → "Families I belong to" → "Leave family". You lose access to that family's children, but any memories you contributed stay in their capsule.
Where is my data stored?
AWS in the EU (Frankfurt). GDPR compliant. Cold storage on AWS S3 Glacier with 99.999999999% durability — that's a one-in-a-hundred-billion chance of losing a file.
Can I download my memories — and put them back?
Yes, both ways. Request an export from your profile: you get a ZIP with photos and videos in their original format (JPG, MP4 — they open on any computer, no Nestori needed), letters as text files, and an HTML page that displays them nicely. The archive can also be restored back into your account — if you delete something by mistake or want to rebuild your archive, you upload it and the memories return. Nothing is locked in a proprietary format.
How do I find one memory among thousands?
Search by words in the description, by period (between two dates), by content type (photos, video, voice) and by your own tags. Memories are always ordered chronologically per child, and the app surfaces ready-made collections on its own — “On this day”, a few years ago, or the year in review.
Can I import photos from Google Photos or iCloud?
Not yet — for now you add them manually, which has an upside: you choose what deserves to be kept for 18 years instead of dumping thousands of photos. Google Photos import is on our list. What already happens automatically: each photo's date, time and place are read from the file, and the “On this day” collections and yearly recaps build themselves.

Two minutes today. Everything in 18 years.
