2. The Public API is a set of software tools for working with Social Network data through HTTP-requests. Public API methods are understood as being methods listed at the URL https://vk.com/dev/methods.

If your application has many different links provided by users, use the method utils.checkLink to assess their safety.

2.1 Collect and store user data, including the User ID, for purposes not related to the Application’s operation. The requested data must only be used in the context of the application.
For example, you can cache a user’s friends’ IDs to quickly display the list on a mobile device. However, sending all user IDs to your own server to save them in a personal database just in case is prohibited.

2.2 Transmit any user data that is automatically received through the API (including User ID) to third-party services (such as advertising) either directly or through intermediaries.

2.3 Use custom data in any advertisement, such as referring to a user by name on an advertising banner.
