Write it now.Open it later.
Some thoughts are meant to travel through time. Set down where your life stands today, choose the day it should surface again, and hand it to the person you will be by then.

Today
You put it down and close it
Say what you are hoping for, what has you worried, what you are quietly proud of. Attach a photograph so the feeling has something to hold onto. Pick the day it should come back — a birthday, a graduation, an anniversary, or an ordinary Tuesday twelve months out — and shut it.

Every day in between
It stays shut
No preview, no side door, no talking your way in early. What you get instead is the countdown to whichever letter surfaces next, and a shelf that fills up year by year with the ones you have written and the few you have starred.
-
On the date you chose
It comes back to you
A quiet reminder arrives to say one is ready. Reading it turns into a small ceremony: an introduction to the person you were, a measure of the ground covered since, and a grin at whatever you swore you would do. Two versions of you finally get a word with each other.
Letters can go to someone else, too — sealed today, waiting for a day that matters to them.
Nobody reads it before you do
In force from 26 July 2026 · Novaline Core for iPhone and iPad
The promise this app makes is that a sealed letter stays sealed. That promise would be worthless if the letter were sitting on somebody's server in the meantime, so it isn't. Everything you write lives on your own phone, there is no account attached to it, and the app gathers nothing about you whatsoever.
Nothing is asked of you
Novaline Core opens straight into use. It has no sign-up, no profile and no password. It will not request your name, your email address, your birthday or your whereabouts, and it does not look at device or advertising identifiers.
Where the letters live
The words you type, the pictures you attach, the unlock dates, the starred ones and the ones already opened are all written into the app's own storage on your device. There is no matching copy anywhere else. The developer cannot open your letters early or late, because the developer has never had them.
How the reminder finds you
The nudge on unlock day is a notification your own phone schedules and delivers, using iOS's built-in timer. No push service is involved, no device token is registered with anyone, and the reminder works with the phone in airplane mode from the day you seal the letter to the day it opens.
Photographs
Adding an image goes through the standard iOS picker, so the app only ever sees the one picture you hand it and never the rest of your library. That copy is stored beside the letter and travels no further.
If you pass a letter on
Should you decide to send an opened letter to somebody, the iOS share sheet does it, at the moment you ask and not before. Once it lands in Messages, Mail or anywhere else, it lives by that app's rules from then on.
No outside code
The build carries no analytics package, no advertising network, no crash-reporting service and no tracking beacon. Nothing counts your taps and nothing is sold, because nothing is recorded in the first place.
Younger writers
No information leaves any user's device, so none leaves a child's either. There is no record on our side that COPPA, the UK Children's code or comparable rules elsewhere could apply to.
Erasing what you wrote
A letter can be deleted from inside the app at any point, sealed or opened. Removing Novaline Core from the device takes the whole collection with it, permanently, with nothing held elsewhere to bring back.
One thing worth knowing: if your phone backs up to iCloud or to a computer, your letters may sit inside that encrypted backup. Those backups are yours and Apple's, governed by Apple's terms rather than by this page.
Revisions
If a future release does anything not described here, this page is corrected before that release goes out and the date at the top moves accordingly.

Trouble with the app, an idea for it, a date format it handles badly, or a story about a letter that landed well — all of it is read by one person.
