So Google is starting to charge for translations, and MS future fee structure is unknown (how long will they offer a free service?)

If I purchase your product, is there any assurance that I will have translation service in the future without having to pay an additional per-word charge?

That is to say, if in the future, MS stops their free service, and/or you are unable to find any free APIs, will I be able to get a refund on your software?

Thank you.
