If you're using Langwill Currency widget and have enabled auto currency switching, we will display prices in the visitor’s local currency based on Shopify's exchange rates and their location.
However, the currency used at checkout is controlled by your Shopify Markets settings.
If you'd like customers to pay in their local currency to improve conversion rates, follow the steps below:
✅ Option 1: Enable “Use local currencies”
1. Go to Shopify Admin > Settings > Markets
2. Select a market, then enable “Use local currencies”

⚙️ Option 2: Assign a Default Currency per Market
You can also assign a default currency for each market. After setup, customers from that market will check out using the currency you selected, regardless of their location.
