Crowdin Android SDK pricing

Does Andorid SDK cost something? Like I’ve seen few apps, like Intecrom, Contentful, that has 2 weeks free and then some additional payments for usage. So just wondering whether SDK for Android is paid option or not?

Also, what’s the security structure of it? Where data is proceeding?

Should be free if you keep your limits low.

The redirect link says it has additional pricing:

Requests $3 / 1M
Data transfer $2 / 10GB

If you have up to 1M requests and 10GB of data transfer, it’s free.

So in otherwords, it’s free while you keep requests up to 1 M and data transfer up to 10 GB
