Children from kindergarten through the upper years of primary school. Each story comes in L1 (grades 1–2), L2 (grades 3–4) and L3 (grades 5–6), and we recommend stories based on the grade and English level you shared at sign-up.

You can switch the level of any story when you choose it.

Everything is free for now. If we introduce paid plans, we'll tell you in advance, and you'll only be charged if you agree.

Yes. Add each child under Parent Zone › Manage children. Reading records, conversations and parent letters are kept separately for each child.

Set a child PIN if you'd like to keep siblings out of each other's space.

In weeks when your child uses Lento, we send a letter about your child's week every Friday evening (Korea time). No letter is sent in weeks without activity.

You can reread letters anytime in Parent Zone › Letter, and choose whether to get them by email in My Page › Notifications.

Lento doesn't push your child to use it more than your child wants to. If there's no activity in a week, we don't generate a report — we wait for more moments to gather instead. If there's a little activity, we write a short letter from what's actually there.

Yes. On iPhone, open lento.kids in Safari and tap Share › "Add to Home Screen". On Android, open the Chrome menu and tap "Install app" (or "Add to Home screen").

Once installed, Lento opens without the browser bar, and you can control audio from the lock screen.

Things your child shares while reading may be quoted in letters. Anything your child calls a secret is not shown.

But if your child seems to be in real distress or danger, we will always tell you, even if it was called a secret. Your child is told about this promise during onboarding.

If your child says something during a conversation that suggests your child may be in serious distress or danger, we alert you right away by email and push notification. These alerts protect your child, so they can't be turned off.

AI can be wrong. If you get an alert, talk with your child calmly, and seek professional help if needed.

On the PIN screen, tap "Forgot your PIN?" and confirm your account email and password to create a new PIN.

If you only sign in with Google or a passkey and don't have a password, email us at the address above.

Tap "Forgot password?" on the sign-in screen and enter your email to get a reset link.

If you signed up with Google, use the Google button instead of a password.

In the reader, open Settings › Reading language and choose Korean, British English or American English. For stories with narration, the audio switches too.

Some stories or languages don't have narration yet; in that case only the text changes.

In My Stories, tap Select, choose stories and save them as a PDF.

Stories moved to the trash can be restored for 15 days before they're permanently deleted. Parents are notified when a story is moved to the trash.

Delete a child under Parent Zone › Manage children. You can undo for 15 days; after that we send you a farewell letter about your time together and then delete the data.

To close your account, go to Parent Zone › Settings › Close account. You can cancel for 15 days; after that we send a final letter for each child and then delete everything.
