Hello Adam,
Thanks for the list of links! We are particularly concerned by this paragraph under the Terms of Service (under section 'Your Content in our Services'):
"When you upload, submit, store, send or receive content to or through
our Services, you give Google (and those we work with) a worldwide
license to use, host, store, reproduce, modify, create derivative works
(such as those resulting from translations, adaptations or other changes
we make so that your content works better with our Services),
communicate, publish, publicly perform, publicly display and distribute
such content. The rights you grant in this license are for the limited
purpose of operating, promoting, and improving our Services, and to
develop new ones. This license continues even if you stop using our
Services (for example, for a business listing you have added to Google
Maps)."
(this paragraph is in the current ToS and also in the new ones, which will be in force starting from 22nd Jan 2019)
What does this mean for a person or company using Google Translate? Is there any difference between the free web service and the API, or do the ToS apply to both? How can I know that the information I'm typing into GT won't be reused and/or publicly available to anyone? Many people from the localization industry tend to advise not to use the free web translation service for confidential documents, so I think your suggested solution (developing an internal web interface) can be more reassuring.
Thank you!
