Alkemics attaches great importance to privacy compliance. The purpose of this policy is to keep you informed about the way Alkemics uses the data collected via its services in order to facilitate users’ path to purchase.

1 – About Alkemics’ services

Alkemics provides tools to retailers and consumer brands (hereinafter referred to as “Partners”) enabling them to better understand their customers, to address them more relevant messages and to facilitate their path to purchase.

Thanks to this:

>Customers showing certain consumption characteristics at a “retail” Partner (that is to say a retailer which is an Alkemics partner) will be sent better targeted advertisements, in connection with such customers’ purchases;

>When faced with an advertisement, customer behavior (click, visualization…) is compared to the purchases it makes at a “retail” Partner (purchase of advertised products, competing products…) in order to determine whether the advertisement is effective;

>Advertisements addressed to customers can offer direct purchase in one of the stores of the retail Partner where customers shop;$

Such information may directly stem from customer interactions on said Websites, or from information obtained by our Partners directly from customer, for example via their loyalty programs.

2 – Our technology


Alkemics “tags” visitors to its Partners’ Websites with browser cookies. A technical identifier is given to users tagged by Alkemics and stored in a browser cookie.

Pixel tags are used by Alkemics in order to transfer the data submitted by our Partners’ Websites to Alkemics’ servers. The information thus collected is stored in our data bases. However, at no time does Alkemics collect personally identifiable information such as names or addresses, meaning that data thus collected does not enable Alkemics to connect such data to your identity.

Alkemics’ opt-out page enables the cookies located on the internet user’s browser to be removed and replaced by an opt-out cookie displaying your wish not to benefit from Alkemics’ services (see below for more information).

What is a cookie?

A cookie is a small text file stored in a user’s computer for recording purposes. There are two types of cookies:

>Session cookies are used to make it easier for you to navigate on websites. Session cookies have a limited lifetime and expire when you close your browser.

>Persistent cookies allow us to record and identify the interests of customers who benefit from Alkemics’ services in order to enhance their experience on our Partners’ Websites. For example, when you place an online order for food on our Partners’ Websites, cookies are archived in your terminal, if you give your consent. Such cookies are used to recognize you when you connect to ours Partners’ Websites. This enables us to personalize the content we offer you and store your preferences in the computer’s memory (for example, your favorite retailer). For example, they enable Alkemics to display on websites you consult purchasing interfaces allowing you to purchase the products described therein, at your habitual retailer, and without having to visit such retailer’s website. Your path to purchase is therefore facilitated and allows you to save time.

Persistent cookies are stored for a longer period of time and remain archived on your computer after you have visited our Partners’ Websites. You can remove them by following the instructions provided in the “Help” section of your browser.

What is a pixel?

A pixel (also known as a web beacon) is an often-transparent graphic image; usually it is no larger than a 1×1 pixel and is placed in a Website.


In environments that do not support cookies, such as mobile applications, we can use technologies for the same purpose of cookies.

To display our advertisements in mobile applications, we collect identifiers, such as Android Id or IDFA according to the operating system of your mobile. Such identifiers consist in a string of anonymous and random characters enabling the simple authentication of your phone, which Alkemics has recorded by means of a hash function (a non-reversible encryption method).

3 – Data collection and use


We only collect data relating to your browsing or purchasing behavior via cookies or equivalent identifiers that record

>events related to your activity on our Partners’ Websites (such as products and pages viewed, key words entered in search engines, purchased goods, consulted stores, hashed or salted versions of customer numbers…);

>events related to your purchases in the framework of your loyalty program, such as they were submitted by our Partners;

>information related to your device (computer, tablet or smartphone) including the model, version of the operating system, the device’s unique identifiers, information relating to the mobile network, the browser type and language, the time and date of visit to our Partners’ Websites, the url source;

> and events related to the interaction with the advertising banners (postings, clicks, adding items to a basket) such as the number of advertisements that were displayed. We collect such information in order to improve the pertinence of the products offered (availability, format, quality, price, promotion);


We do not know who you are. We do not know your address, place of work, date of birth, email address, telephone number or any other information that could help us identify you. We do not use or store your IP address for targeting purposes.

We do not collect any hardware-based identifiers such as UDID, Mac address (physical identifier stored on a network or interface card). We do not collect any sensitive information (religion, political views, etc…).

We do not create segments designed to specifically target children under the age of 13.

We do not process any information which could be used by Alkemics to determine the personal identity of users.

4 – French Data Protection Act compliance

Within the framework of our relations with our Partners, we ensure that they strictly comply with the French Data Protection Act of January 6, 1978, as amended in 2004, and undertake to implement appropriate information-related measures and measures relating to the obtaining of your consent to place cookies on your terminal.
