Frequently Asked Questions
What exactly gets translated in the screenshot?
All visible text is localized while the layout, branding, UI structure, and icons are preserved.
Do I need both a language and a country?
Yes. The language drives translation, and the country controls cultural details like currency and date formats.
Can I start from screenshots I already have?
Yes. Use `get_screenshots` to pull the originals, then pass each image into `localize_screenshot`.
What do I get back after localization?
You get a JPEG ready for App Store submission, already adapted to the target market.
