Photograph a Dutch letter and read what it says and what you have to do, in your own language. The photo stays on your phone. Dutch letters are hard to read even if you speak Dutch. Photograph one and Letrin tells you, in your own language, what it says, what it wants from you and by when. It works on any letter you cannot read. A tax assessment or a fine, yes, but also a rent increase, a hospital bill, a notice from the housing association, a letter from a school, an insurer or a neighbour. If it is on paper, Letrin will read it. THE PHOTO NEVER LEAVES YOUR PHONE The text is read on the device itself, offline. Only the text you approve is sent, and only to write the explanation. No copy of your letter is kept. No account, no sign-in, no history. YOUR DETAILS ARE HIDDEN AUTOMATICALLY Name, address, BSN, IBAN, phone number and reference numbers are found and hidden before anything leaves. You see exactly what will be sent, and you can hide more yourself. WHAT YOU GET • What kind of letter it is and who sent it • What is being asked of you, in one sentence • Step by step what to do • Dates and amounts, with the deadline called out • What to watch for: penalties, objection windows, common mistakes • A reply in correct Dutch for you to check and send yourself • A reminder before the deadline, and the date in your calendar IN 19 LANGUAGES Dutch, English, Turkish, Arabic, Polish, Ukrainian, Russian, German, French, Spanish, Portuguese, Italian, Romanian, Bulgarian, Persian, Hindi, Chinese, Indonesian and Vietnamese. WHAT IT COSTS Every phone gets three explanations free. After that there are two ways to carry on. Letrin Plus is a subscription: 20 letters every 30 days, with reply drafts and calendar export. • A monthly plan, renewed every month • A yearly plan, renewed every 12 months There is no free trial; the three free explanations take its place. Payment is charged to your Apple Account when you confirm. A subscription renews automatically unless you cancel at least 24 hours before the period ends. Manage or cancel it in your Apple Account settings; deleting the app does not cancel it. The price of each plan is shown in the app, in your own currency, before you confirm, and differs by country. Letter packs are bought once and never expire: 1, 5 or 15 letters. Nothing renews. A pack is only used once a subscription allowance has run out. AN AI WRITES THE EXPLANATION, AND IT CAN BE WRONG Letrin reads your letter with an AI model. It can misread a blurry photo, miss a detail, or get an unusual letter wrong. Treat what it says as help with understanding, not as a final answer, and always check dates, amounts and deadlines against the letter itself. Letrin is not legal, tax, immigration or financial advice, and it is not a lawyer or an adviser. For anything with real consequences, contact the organisation that wrote to you, or free legal help at het Juridisch Loket.

Fixed a bug that stopped the letter explanation from opening on some phones. Deadline reminders are now more reliable. Small visual improvements.
