What does setting a default language in my store truly imply?

Topic summary

Main issue: Whether setting English as the store’s default will automatically show other languages to visitors based on location or system preferences.

Key points and clarifications:

  • Default language = the primary/fallback language shown when no translation or detection is applied. With English as default, all visitors see English unless another mechanism intervenes.
  • Shopify supports localization via the Translate & Adapt app, CSV export/import of translations, or compatible third‑party translation apps. If a translation is missing, content falls back to the default language. Product URLs remain in their original language.
  • Shopify does not auto-detect a visitor’s language by default. Automatic language selection based on browser/language or location requires a third‑party language detection app plus provided translations.

Updates/outcomes:

  • Confirmation that auto language switching is not built-in; a detection app is needed.
  • A video resource was shared to further explain default language behavior.
  • The original poster notes they can set different default languages per country while keeping English as the base language (not detailed by staff in-thread).

Open item:

  • A request for recommended third‑party automatic language detection apps remains unanswered. The discussion is ongoing.

Thank you for the message, Moira.

I think your answer is in your last sentence. When I set English as default, a user in germany will see website the first time in English unless I use a language detaction app. Is my understanding correct?

Thank you
