Why Your App Needs Professional Localization
Users don’t download apps they don’t instantly connect with. Language barriers and poorly adapted interfaces push potential users away before they even give your app a chance. CCJK removes those barriers.
With more than two decades of experience in app translation and localization, we adapt your app’s content, design, and functionality to match what users in each target market actually expect. Not a rough translation. A version of your app that genuinely belongs in each market.

Our Mobile App Localization Services
Language Translations
We translate every user-facing element, including UI text, notifications, store descriptions, and onboarding flows, with context, not just word-for-word translation. The copy fits the interface and reads the way a native speaker would actually write it.
Cultural Localization
We adapt icons, symbols, colors, and imagery to match what users in each target market actually expect. The details that seem minor are often the ones that determine whether someone trusts your app or deletes it.
Functional Localization
Date formats, currencies, RTL layout support, measurement units, and regional compliance requirements all get handled before your app ships. It should work correctly in every market from day one, not after user complaints roll in.
UI and Metadata Adaptation
We adapt your layout alongside the language and apply the same attention to your store metadata, including the title, description, keywords, and screenshots. All of it affects how your app ranks and whether users click through.
App Store Optimization
We research the right search terms per locale and adapt your store copy around them. A keyword that drives downloads in the U.S. may have no traction in South Korea, and we account for it.
Testing and QA
We test every localized build for language accuracy, layout stability, and functional performance before delivery. Anything that doesn’t pass is fixed and retested, not flagged and forwarded.
How We Localize Your App
Preparation and Planning
We map out your target markets, timelines, and style guidelines before any translation begins. This ensures every linguist on the project works from the same reference point.
Project Execution
Our localization teams adapt your app’s text, visuals, and interface with each target market in mind. You receive a complete, review-ready version at the end of this phase.
Post-Localization Testing
We test the finished build for language accuracy, layout stability, and functional performance. Anything that falls short is fixed before the final version reaches you.

XiaomiFAQs
frequently asked questions
How is localization different from translation?
Translation converts text from one language to another. Localization goes further by adapting the entire app experience, including design, functionality, cultural references, and regional conventions, so it feels native to each market, not just understandable.
What languages do you support for localization?
We support 230+ languages across 800+ language pairs. That covers widely spoken languages like Spanish, Mandarin, Arabic, and French as well as niche dialects and regional variants that most providers don’t offer.
How much do localization services cost?
Pricing depends on the number of languages, content volume, platform type, and turnaround time. There is no fixed rate because no two projects are the same. Share your project details and we will put together an accurate quote.
What payment options do you accept?
We accept all major payment methods. Our team will walk you through the available options when your project is confirmed.
What measures do you take to ensure my documents’ security?
We operate under strict confidentiality agreements and secure file handling protocols. Your source files, app content, and project data are never shared outside the assigned project team.
Could you also help with proofreading or editing of translated materials?
Yes. If you have existing translations that need a second pass, our editors can review them for accuracy, tone, and consistency. This service is available independently of a full localization project.
Is desktop publishing or formatting included in your services?
Yes. We handle layout and formatting adjustments as part of the localization process, particularly where translated text affects the visual structure of your app or store materials.
Are your localization services certified?
Yes. CCJK is ISO certified, and our processes meet international standards for translation and localization quality. Certification details are available upon request.
