Please can I refer you to the End User Licence Agreement and the NBS Chorus Terms and Conditions which already include confidentiality provisions and terms on use of personal data.
You may also wish to review the NBS Privacy Policy.
Together these terms apply to the provision of NBS Products and Services. Having reviewed the NDA you kindly provided there is already similar provision in the NBS terms you have entered into.
If you have any further queries or wish to discuss this further please contact my colleague, Sascia Elliot, In House Legal Associate.
