Support — One Little Line

Getting started

You don’t need an account to begin — open the app and write your first little line. A single sentence a day is the whole idea: a thing they said, a face they made, a first.

Writing a memory

Write or dictate — type it, or tap the mic and just say it.
Add a photo when it helps. Portrait and landscape photos keep their natural shape.
A sentence is enough — save a small moment and return to your day. You can choose an earlier date for an older memory.

Reminders & notifications

Set a gentle reminder at a time that fits your day from Settings in the app. Reminders only arrive if you’ve allowed notifications for One Little Line on your device — you can turn this on or off any time in your device settings.

Finding your memories

Memories: browse the archive, search for a word, and choose Preview or Full to change how much of each memory you see.
Calendar: return to a particular day or month. Each memory keeps your child’s age with it.
Sky: where enabled, explore your memories as stars and open a moment from its month.

Monthly letters

Find your keepsakes in Letters. AI helps gather the memories you keep into a monthly letter or snapshot. You can read them, edit where the feature is enabled, and export a PDF. Read a fictional sample letter.

Care Circle — writing together

You can keep a child’s memories together with the people who love them. Invite your partner, a grandparent, or a co-parent to a child’s Care Circle — or join one you’re invited to.

Owner & co-writers — the person who created a child’s profile is the owner and manages the circle, including who can write and removing co-writers.
Everyone sees the child’s archive — all the memories, photos, and monthly letters for that child are shared with the circle.
Your words are yours — each memory shows who wrote it (your signature, like Mom or Dad). You can edit or delete only the memories you wrote.
Leaving or being removed — memories you wrote stay with the circle, still attributed to you.
If you delete your account — you choose whether your memories stay (without your name) or are deleted. Ownership of a shared child passes to a remaining member so the archive is never lost.

We can’t mediate family disputes — the owner controls the profile and the circle. You’re responsible for whom you invite and what you add to a shared child.

More than one child

Keep all your children in one app. Switch between them from the top of the home screen, and write for each — or share only the child you choose with a Care Circle.

Your account & sign-in

You can start as a guest. Sign in to sync your memories and take part in a child’s circle. Choose Google or Facebook, or Apple on iPhone. Your guest memories carry over when you sign in.

Subscription & billing

One Little Line is free to start. Some features may require a subscription. Any available trial, current pricing, and subscription terms are shown in the app before you subscribe. Subscriptions are billed through the App Store or Google Play.

Manage or cancel any time — on iPhone: Settings → your name → Subscriptions. On Android: Google Play → Subscriptions. Cancelling stops future charges.
Restore purchases: use the same store account that purchased the subscription, then choose Restore Purchases in the app. Contact us if your paid access still does not appear.
If your subscription ends: some features may no longer be available. Access and retention follow the current product rules described in our Terms. Export a copy of important memories for your own records.

Export & delete

Export your memories and letters from the app to keep an independent copy. You can delete individual memories or your account from Settings. Our Privacy Policy explains retention and what happens when you delete data.

Something not working?

Reminders not arriving? Check that notifications are allowed for One Little Line in your device settings, and that a reminder time is set in the app.
Sign-in or purchase trouble? Tell us which sign-in method you use and what error appears. For a missing subscription, try Restore Purchases. Never send us your password.
Anything else — email hello@onelittleline.com with what happened (and your device model if it’s a bug), and we’ll help.

Privacy & terms

Read our Privacy Policy and Terms of Service. One Little Line is made in the EU, and your memories are private by default.
