Mottak SMS Console
Privacy-First SMS System for Norwegian Asylum Centers
Project Overview
A 100% offline, GDPR-compliant SMS mass messaging system for Norwegian asylum reception centers (asylmottak). Enables multilingual communication with residents via Bluetooth, supporting 9 languages with complete privacy protection.
The Challenge
Norwegian asylum reception centers needed a way to send personalized SMS messages to residents in multiple languages, but strict GDPR requirements meant no cloud services, no data uploads, and complete privacy for vulnerable populations.
Our Solution
Built a dual-component system: a Next.js web console running on Windows for campaign management, connected via Bluetooth Low Energy to a Kotlin/Compose Android app that sends SMS messages. All data stays local, phone numbers are never stored, and messages are automatically personalized in each recipient's preferred language.
Key Results

- 9 languages supported with auto-translation
