Frequently asked questions

Does Lumi Letters Lite work without an internet connection?

Yes. The App Store listing for Lumi Letters Lite states that its core processing happens on your device, so it keeps working in airplane mode or with no signal. Downloading the app itself and making a purchase still need a connection, because those go through the App Store.

Is this a subscription?

No. The listing describes a one-time purchase rather than a recurring subscription. You can always confirm what you are being charged for on the App Store product page before you buy, and review anything active under Settings → your name → Subscriptions.

Where do my exported files go?

Exports go through the iOS share sheet, so the destination is whatever you pick — Files (On My iPhone or iCloud Drive), Mail, Messages, or another app. If you can't find a file afterwards, open the Files app and check Recents.

I paid but the app still shows the locked version

One-time purchases are tied to the Apple Account that bought them. Sign in with that same account (Settings → your name → Media & Purchases), then use the app's restore option if it offers one, or reinstall the app from the App Store's Purchased list. Purchases made with a different Apple Account, including a family member's, will not appear.

I switched to a new iPhone — do I have to pay again?

No. Sign in to the new device with the same Apple Account and re-download the app; the purchase belongs to the account, not the handset.

How do I request a refund?

Refunds for anything bought on the App Store are handled by Apple, not by the developer. Go to reportaproblem.apple.com, sign in, find the purchase and choose "Request a refund". We can't issue, speed up or overturn an App Store refund decision, but do tell us what went wrong so we can fix it.

How do I delete the app and everything it stored?

Touch and hold the app icon → Remove App → Delete App. Deleting an iOS app removes its sandbox — the documents and settings it kept on the device go with it, so export anything you want to keep first. What the app stores and where is described in our privacy policy.

How do I make sure I'm on the latest version?

Open the App Store, tap your profile picture, and pull down to refresh the pending-updates list. If the app appears there, tap Update. Turning on Settings → App Store → App Updates keeps it automatic.

How do I stop my child making purchases by accident?

iOS can block them at the system level, which is stronger than anything an app can do: Settings → Screen Time → Content & Privacy Restrictions → iTunes & App Store Purchases → In-app Purchases → Don't Allow. Set a Screen Time passcode that is different from the device passcode so it can't be undone by the child.

How do I keep my child inside one app?

Use Guided Access: Settings → Accessibility → Guided Access, turn it on and set a passcode. Then open the app and triple-click the side button to lock the device into it. Triple-click again and enter the passcode to leave.

Which devices and iOS version does Lumi Letters Lite need?

See the App Store product page — the Information section there is always the authoritative, up-to-date answer for compatibility, size and languages.

Troubleshooting

The app won't open, or closes straight away

Force quit it first: swipe up from the bottom of the screen and pause, then swipe the app's card away. Reopen it. If it still closes, restart the device — that clears the majority of one-off launch failures.

It feels slow, or freezes on a big job

Check free storage in Settings → General → iPhone Storage. iOS gets unpredictable below roughly 1 GB free, and anything that writes files (exports, scans, image processing) is the first thing to suffer. Also close other apps that are working in the background.

Something looks broken after an update

Update iOS itself (Settings → General → Software Update), then update the app. A mismatch between an old iOS and a new build is a common cause of layout or feature glitches.

Last resort: reinstall

Export anything you want to keep, delete the app, then reinstall it from the App Store's Purchased list. Paid unlocks belong to your Apple Account and survive a reinstall; data stored only on the device does not.
