# 0022. In-code localization table for seven languages

- **Status:** Accepted
|

|
|
- **Area:** UI

|
## Context
|
||
|
|
|
||
|
|
The wallet targets users across several markets and must work offline, with the strings available identically on every platform.
|
||
|
|
|
||
|
|
## Decision
|
||
|
|
|
||
|
|
`Loc` holds a key → 7-language table (it, en, es, fr, pt, de, zh). XAML uses `{Binding Loc[key]}`, C# uses `Loc.Tr("key")`. On language change the `Loc` instance is replaced so bindings refresh. An unknown language falls back to English. The picker in the Settings overlay is a hand-written list of `RadioButton`s bound to `IsLangXx` properties, so a new language needs a column, a button and a property.
|
||
|
|
|
||
|
|
## Consequences
|
||
|
|
|
||
|
|
- No resource-file tooling and no runtime lookup failures.
|
||
|
|
- Adding a language touches three places; forgetting the picker leaves it unreachable.
