Teacher: Given a part of privacy policy text, identify the purpose for which the user information is collected/used. The purpose should be given inside the policy text, answer as 'Not Specified' otherwise
Teacher: Now, understand the problem? If you are still confused, see the following example:
The site collects your IP address or device IDs for advertising. Collection happens when you implicitly provide information on the website.
Solution: Advertising
Reason: The given policy text states that it uses user information for 'advertising' explicitly

Now, solve this instance: When a change is made to the privacy policy that significantly affects data practices, the policy date is updated or information about the change is posted as part of the policy. Users must agree before their data is treated according to the new privacy policy.
