# Open-source dictionaries bundled with this app

This app is a **reader**: it ships with open-licensed dictionary data only, and
loads further dictionaries only from files the user provides. Attribution below
covers everything bundled in the `samples/` folder of a public deployment.

If you add another open dictionary (e.g. GCIDE, a full Wiktionary build), add a
row here **and** to the "Dictionaries & licenses" section in the About panel
(`index.html`) before deploying. CC BY-SA content requires visible attribution.

Commercial dictionaries (OALD, LDOCE, …) are **never** bundled or distributed by
the public deployment — users load their own files locally via ⚙ Advanced.
