MDAC One-Click is a Chrome extension that fills the Malaysia Digital Arrival Card (MDAC) form on imigresen-online.imi.gov.my with traveller details you save in the extension.
The travellers you add (name, passport number, date of birth, nationality, place of birth, sex, passport expiry, email, mobile number) and the trip presets you add (travel mode, transport number, port of embarkation, accommodation address). Travel dates are never stored.
All of it is kept in chrome.storage.local in your own browser profile. It is not synced to your Google account and it is never sent to the developer or any third party.
Only into the MDAC register form on https://imigresen-online.imi.gov.my/mdac/, and only when you press Fill. Submitting that form to the Immigration Department of Malaysia is your action: the extension never submits it for you, and never interacts with the form’s verification slider.
The extension has no server, no analytics, no tracking and no remote code. Its only host permission is https://imigresen-online.imi.gov.my/mdac/*.
If you use Scan a confirmation email, the screenshots you choose are read by an OCR engine (Tesseract, shipped inside the extension as WebAssembly) on your own device. The images and the text read from them are kept only in memory while you review them and are discarded afterwards; only the traveller and trip-preset fields you choose to save are stored, locally, like any other entry. Nothing is uploaded.
This is a local text-recognition engine, not an AI service or large language model: no image, text or result is sent to Anthropic, OpenAI, Google or anyone else, and no account or API key is involved. Every value it reads is shown to you for review — marked as read, unsure, missing, kept from your saved traveller, or edited by you — and nothing is saved until you press Save.
MDAC One-Click is an independent open-source project. It is not made, endorsed or operated by the Immigration Department of Malaysia or any government. The official MDAC service is free at imigresen-online.imi.gov.my.
