Privacy policy

ADMAX is a programmatic mediation platform that helps serve digital ads on websites and / or mobile applications intended to their users.

In the course of its business, ADMAX is likely to process your personal data in order to serve you the best-suited ads for your profile and report on those ads to our publisher partners.

ADMAX takes very seriously the protection of your personal data, processes and uses your personal data in accordance with the provisions of both the General Data Protection Regulation (EU Regulation 2016/679) and the French law No. 78-17 of January 6, 1978.

Data security and storage

The data processed by ADMAX is processed within the European Union.

Security is at the core of ADMAX concerns which implements the appropriate technical and organizational measures to ensure the security and confidentiality of this data and to protect it from any access, modification, disclosure or deletion by unauthorized persons. Access to your personal data is strictly restricted to certain employees of ADMAX specifically appointed for such purposes in connection with their duties, and to technical partners of ADMAX who contribute to the delivery of its services.

ADMAX stores the data for a maximum of 13 months following the date of their reception. Shorter durations are also implemented to make sure data is not kept for longer than necessary in a form that identifies a person. Location data is stored for 3 months, after which only pseudonymized data (without indirect identifiers such as advertising identifiers) is kept for statistical analysis.


A “cookie” is an IT file intended for the collection of information from your browser. We use cookies or similar technologies to identify browsers or devices across sessions. The lifetime of such advertising cookies does not exceed 12 months.

You may access all of the information contained in the files related to the cookies used by ADMAX in compliance with the provisions of French law No. 78-17 of January 6, 1978. You may, if you wish, oppose the use of cookies by ADMAX by selecting the relevant settings of your browser in order to disable them (the help section of the browser used indicates how to do so).

Device IDs

A “Device ID” is a unique identifier allocated by the operating system of your terminal in order to allow your identification through various applications. You may access all of the information contained in the files related to the device IDs used by ADMAX in compliance with the provisions of law No. 78-17 known as informatique et libertés of January 6, 1978.

You may, if you wish, oppose the use of device IDs by ADMAX by following the instructions of the manufacturer of your terminal. As an example, the instructions for Android and iOS are as follows:

– for Android: open the Google Settings (or go to “settings” and then “Google”) and select the “Advertising” section
– for iOS: open the “Settings” and go into the “Privacy” section, then select “Advertising” and activate the “Limit Ad Tracking” function
