IP address masking is a tag setting that allows you to specify how Yandex Metrica should process and store the IP addresses of your site users.

You might need this setting in order to meet requirements for personal data security, including confidentiality policies on third-party resources and federal laws.

By default, Yandex Metrica stores the entire depersonalized IP address of the user. The IP address is used to determine a site user's location more precisely, but it isn't shown in any of the service's reports.

  2. On the Tag tab, go to Additional data processing conditions and turn on the Do not store full IP addresses of site visitors option.

You can also enable IP address masking when creating a tag, in the Additional data processing conditions section.
