API and Hub: Confidentiality

Microsoft Translator API:
Microsoft does not share the data you submit for translation with anybody. Any sampling taken will be used exclusively to improve Microsoft Translator, or deleted within 30 days. Microsoft Translator takes a sampling of at most 10% of unrelated, non-consecutive sentences. If you are concerned about the potential of samples being stored, and you are subscribed to the Microsoft Translator Text API in the Azure portal with a minimum monthly volume of 250M characters or more (i.e. S2 to S4 subscription tiers), you can opt out of any sampling. Just let us know the Resource ID of your Microsoft Translator Text API subscription by submitting a request using the process detailed at www.microsoft.com/translator/notrace.aspx , and we'll exclude the content of your requests from ever being written to non-volatile storage.

Microsoft Translator Hub:
The material you use for training on the Translator Hub is stored encrypted in your workspace. You may invite whoever you like into the workspace, identified by an email address and authenticated with a Microsoft Account. The people you designate as co-owner have access to your training material and training runs the same way you have. Microsoft will not share the data with anyone else. You can delete the data in your workspace at any time, as long as it is not used in any training. Microsoft will use the data that you include in a training to build the custom translation system for you. The custom translation system will be deployed on Microsoft's servers, and are then usable via the Microsoft Translator API. Anyone who knows the category ID of your custom system can use it using their own Microsoft Translator Text API subscription account. There is no method allowing you or anyone else to generate the original training material out of the trained system. Microsoft may use the data in your workspace to improve Microsoft Translator, unless you have a paid Microsoft Translator Text API subscription account, and check the "Keep data private" box in the Settings tab on the Translator Hub.

Copyright and Intellectual Property:
Translation, or use of a document for training on the Microsoft Translator Hub, does not alter the ownership of the intellectual property contained therein.
