Lay the page flat, use even light, and keep the whole page inside the frame. Shadows, folds and very faint print are what usually break recognition. The covering screen shows exactly what was read: if the text there is wrong, retake the photo before asking for an explanation.

Yes, up to six pages in one document. Photograph them one after another or pick them from your gallery, and they are read as a single letter, for one credit like any other.

An AI model writes it, and it can misread a blurry photo or an unusual letter. Always check dates, amounts and deadlines against the letter itself. If something is clearly wrong, tell us the type of letter and the sender, never the letter itself.

Scanning, text recognition and covering your details work fully offline. Only the explanation needs a connection, because it is written by an AI model. Reminders also fire offline, because your phone schedules them.

Letrin is tuned for Dutch official mail, but it reads any letter you can photograph: a hospital bill, a school letter, an insurer, a landlord.

Apple and Google handle the payment, and it sometimes arrives a minute late. Open Settings in the app and tap Restore purchases. If it still does not show up, send us the store receipt, never your card details.

In your store account, not in the app. On iPhone: Settings, your name, Subscriptions. On Android: Play Store, Payments and subscriptions. Deleting the app does not cancel a subscription.

Apple and Google are the sellers, so refunds run through them and follow their rules. On iPhone use reportaproblem.apple.com, on Android the Play Store order history. Write to us as well if something went wrong on our side.

No. A Plus period gives 20 credits per 30 days. Purchased credit packs are different: they never expire and are used only after the Plus allowance runs out.

No. The photo is read on your phone and never uploaded. Only the text you approve on the covering screen is sent, and no copy of it is kept: it exists for the seconds the request takes and is never written to a database or a log.

Settings, then Delete everything on this phone. Letters, explanations, settings and the encryption key are destroyed.

Settings, then Privacy, then turn off sending covered text to the AI. The rest of the app keeps working; only new explanations stop.

Write to our privacy address below. Almost everything about you is on your phone, where the settings above give you these rights directly. We answer within a month.

Check that notifications are allowed for Letrin in your phone settings, and that battery saving is not stopping the app. Reminders are scheduled by your phone, so a phone that is switched off will deliver them late.

Seven days before the deadline, two days before, and on the morning of the deadline itself. You can turn them off per letter or entirely in Settings.

Yes, one tap exports it to the calendar you already use. That copy lives in your calendar afterwards and is no longer managed by Letrin.
