## What is Min Saga?
**Min Saga** (Norwegian for “My Saga”) is the customer app for [Saga Mobil AS](https://sagamobil.no). It lets you manage your mobile subscription without calling customer service — check data usage, buy extra datapacks, turn products on or off, and manage SIM cards, all from your phone.
The experience is built around an **aurora-themed** visual design: deep forest-green backgrounds with flowing northern-lights-style data visualizations, so usage information feels clear and engaging rather than like a dry utility bill.

## How it works — the big picture
When you open Min Saga on your phone, the app talks securely to Saga Mobil’s **API** — a Go service running in **Docker** on our servers. The API sits between you and Saga Mobil’s billing platform (**eRate**), handling login, security, and Vipps payments so your subscription data stays protected.
The iOS and Android apps are built with **Capacitor**, which packages the same interface into a native app for each platform while keeping one shared codebase.

The app itself is installed from the App Store or Google Play. All subscription actions go through the API, which reads and updates your account via eRate and handles payments through Vipps.
