This policy applies to the use of Metrixlab cookies on third party sites as explained below. MetrixLab takes your privacy very seriously and wants you to be familiar with how we collect, use and protect information.


Metrixlab is a Macromill group company and this policy covers the use of Metrixlab and its affiliates, including Macromill Inc., cookies on 3rd party panel sites. This policy does not apply to panelists or visitors to Metrixlab or Macromill’s own sites (refer to separate policies found on our website).


Our technology and cookies are used to understand what advertisements panelists have been exposed to so that we can measure the impact and effectiveness of those advertisements. We will invite certain panelists to take part in market research surveys to understand if exposure to advertisements has impacted such things as brand awareness and likelihood to purchase. The information we collect is aggregated and no personal identifiable information will ever be shared with a client.

This Privacy Policy can be stored or printed using the buttons at the top of the Privacy Policy.

Information we collect

By implementing Metrixlab’s cookie via a 3rd party panel site we will collect a unique panelists ID Number (Identification Number) that can be recognized by the panel site that you have registered with. Metrixlab does not collect or store any PII (Personal Identifiable Information). The unique panelist ID Number enables Metrixlab to contact the panel you have registered with to invite you to a survey. Metrixlab will collect and store your survey results as well as the unique panelists ID Number. Metrixlab can use the panelist ID Number to determine certain demographics groupings (age range, married or unmarried, male or female) but does not collect or store any personal information such as name, e mail address or date of birth.

Use of cookies on 3rd party panel sites

This policy covers the use of Metrixlab cookies on 3rd party panel sites. Metrixlab works with a number of professional panel companies to obtain market research surveys in addition to operating its own survey panel. Some of those 3rd party panel companies have agreed to implement the Metrixlab cookie to identify if panelists have been exposed to specific advertisements. This information allows Metrixlab to invite certain panelists to participate in surveys to measure the impact and effectiveness of those advertisements. Metrixlab will not have access to any personable identifiable information.
