## What String Manager does

String Manager is TotalCtrl's localization hub. It stores the user-facing text for your apps and platforms in one place, tracks translations into multiple languages, and runs quality checks so nothing ships broken or untranslated.
## Core concepts

- **String set** — a collection of strings, usually one per app, platform, or release. Each set has a primary (source) language and any number of target languages.
- **String** — a single entry with a unique `key` (for example `checkout.button.pay`) and a source value. Strings can carry context notes, placeholders, custom fields, and screenshots.
- **Translation** — the value of a string in one target language. Each translation can be marked **reviewed** once a translator or editor approves it.

## What you can do

- [Create string sets](create-a-string-set) and add target languages.
- [Import and export](import-and-export-strings) in 18 formats (Gettext, Android XML, Apple .strings, XLIFF, ARB, RESX, JSON, YAML, CSV and more).
- [Add strings and enter translations](manage-strings-and-translations), with reviewer sign-off.
- [Run quality checks](run-quality-checks) for missing translations, placeholder mismatches, length warnings, spelling, and grammar.
- [Sync with GitHub](sync-with-github) using ready-made Actions workflows and a webhook.

Because TotalCtrl apps share data, the same canonical contacts, audit log, and AI layer used elsewhere in the suite back String Manager too.
