The Response  
 
MS Teams collects three types of data about the app: error reporting data, usage data and 
census data. Census data includes information like type of device, operating system, user 
language, and a generated specific user ID that is hashed twice in order to anonymise 
individuals. 
 
Highly authorised administrators are the only people who have access to this data. 
 
The time period the data is retained for is currently under review. 
 
Regarding privately owned devices and controls, the University exempts this information 
under Section 31 Law Enforcement of the Freedom of Information Act. 
 
For your information Section 31 says: 
 
31 Law enforcement. 
(1)Information which is not exempt information by virtue of section 30 is exempt 
information if its disclosure under this Act would, or would be likely to, prejudice— 
(a)the prevention or detection of crime, 
 
https://www.legislation.gov.uk/ukpga/2000/36/section/31 
 
The University believes that information relating to Bring Your Own Device Teams data 
download logs and controls are specific to the University and disclosing this information to 
the public would be likely to prejudice our security and crime prevention and detection 
measures.  
 
The University therefore exempts the disclosure of this information under Section 31 Law 
Enforcement.  
 
We hope this may be of use to you.
