With other third-parties for our business purposes or as permitted or required by law:

7. How Do We Work with Other Services and Platforms?

A significant benefit and innovation of MKVS’s Services is that you can connect your Account with a third-party account or platform. For the purposes of this Privacy Statement, an “account connection” with such a third-party is a connection you authorise or enable between your Account and a non-MKVS account, payment instrument, or platform that you lawfully control or own.

When you authorise such a connection, MKVS and the third-party will exchange your Personal Data and other information directly. Examples of account connections include:

linking your Account to a social media account or social messaging service;
connecting your Account to a third-party data aggregation or financial services company, if you provide such company with your Account log-in credentials; or
using your Account to make payments to a merchant or allowing a merchant to charge your Account.

If you choose to create an account connection, we may receive information from the third-party about you and your use of the third-party’s service. For example, if you connect your Account to a social media account, we will receive Personal Data from the social media provider via the account connection.

We will use all such information that we receive from a third-party via an account connection in a manner consistent with this Privacy Statement.

Information that we share with a third-party based on an account connection will be used and disclosed in accordance with the third-party’s privacy practices. Before authorising an account connection, you should review the privacy notice of any third-party that you authorised to have an account connection that will gain access to your Personal Data as part of the account connection. For example, Personal Data that MKVS shares with a third-party account or platform such as a social media account may in turn be shared with certain other parties, including the general public, depending on the account’s or platform’s privacy practices.

8. How Do We Use Cookies and tracking technologies?

When you visit our Sites, use our Services, or visit a third-party website for which we provide online services, we and our business partners and vendors may use cookies and other tracking technologies (collectively, “Cookies”) to recognise you as a User and to customise your online experiences, the Services you use, and other online content and advertising;
