Translate your App Store listing into Czech
Czech (Čeština) — ≈10.7 million native speakers, serving the App Store in Czechia. Here’s what a Czech localization is worth and how to ship one in minutes.
Why localize for Czech?
Czechia has solid iPhone penetration and very little localized competition outside major publishers.
App Store search is per-locale: queries typed on the Czechia storefront match against the cs localization of your metadata. Without one, your app doesn’t rank for Czech searches at all — no matter how strong your English keywords are.
Czech-specific translation tip
Czech users search with and without diacritics ("čeština" and "cestina"). Cover both spellings across keywords.
StoreTranslate bakes language-specific guidance like this into its prompts, along with each field’s character limit and any custom instructions you add — brand terms to preserve, tone to match.
What gets translated
| Field | Limit (Czech included) |
|---|---|
| App name | 30 characters |
| Subtitle | 30 characters |
| Promotional text | 170 characters |
| Description | 4,000 characters |
| Keywords | 100 characters |
| What's New (release notes) | 4,000 characters |
Field-level strategy lives in our guides on translating the description and translating keywords.
How it works
- Connect your App Store Connect API key — credentials are never stored.
- Pick your app, a version in an editable state, and Czech (plus any other targets).
- Run the job. AI translates each selected field within its limit and uploads the cs localization via the App Store Connect API.
- Review in App Store Connect and submit with your next version.

Czech localization FAQ
Which App Store locale code is Czech? ＋
Czech metadata uses the cs localization in App Store Connect, covering the storefronts for Czechia.
Do character limits change for Czech? ＋
No — the App Store’s limits (30 characters for name and subtitle, 100 for keywords, 170 for promotional text, 4,000 for the description) apply to every language, including Czech. StoreTranslate validates each field against these limits before uploading.
Can I translate only some fields into Czech? ＋
Yes. Pick exactly which fields to translate — most developers start with keywords and the description, keeping the app name unchanged. Existing translations are only overwritten if you choose to.
How do I add a Czech localization in App Store Connect? ＋
Open your app in App Store Connect, select a version in an editable state, and add Czech from the language menu — or let StoreTranslate create and fill the localization for you through the App Store Connect API.
