**The integration provides:**
* Over-The-Air Content Delivery – the localized files are sent directly to the application from Crowdin project within a few minutes
* Real-time Preview – all the translations that are done via Editor can be shown in the application in real-time
* Screenshots – all screenshots that are made in the application can be automatically sent to your Crowdin project with tagged source strings. So translators will have the additional context for the source string.
## Key Features
### Affordability
If you have up to 1M requests and 10GB of data transfer, it's free. The higher tiers are priced fairly on a usage basis.
### High speed
Crowdin sends translations via Amazon CloudFront. Users instantly receive translations from the closest server.
### Security
User data is stored exclusively on Amazon Servers, never compromising on data security.
