Strings and limits
I was under the impression that a 'string' was a single 'term' and that the 170 terms used in our app that included around 8 languages would be fine under the 'free' service so we could test this before uploading our common file. Can you confirm that I'm doing this right?

Terms and translations are considered “strings”.
A project’s total number of strings is the sum of its terms and translations. The total number of strings in your account is the sum of the strings in all the projects hosted on your account.
