1) About Zebestof’s services
Zebestof specializes in creating personalized advertisements through “Zebestof Bestofbidder”. We work with online partners to build advertisements for users who visit their websites and with publishers to display personalized advertisements.
Our aim is to deliver advertisements that you might be interested in, based on your recent browsing behavior.
Example of a “Zebestof Bestofbidder” ad: if you visit and browse on Website A, on a subsequent online visit to Website B, you will see ads personalized by your browsing history on Website A.
With our service, you should receive personalized ads that are more relevant for you than the standard advertising you would receive without Zebestof. Click here for more information on Interest Based Advertising.
2) Our Technology
Thanks to these technologies, Zebestof “tags” visitors to its partners’ websites. Users tagged by Zebestof are given a technical identifier. At no point does Zebestof collect identifying personal data such as your name or address. Zebestof only analyses pages viewed made by the visitor and pages visited of the partner for whom Zebestof is delivering ads.
Our partners’ advertisements are displayed on many websites, also known as “publishers.” These publishers may also place cookies on your browser. These cookies are there so that the publishers recognize that Zebestof has a personalized advertisement available for your browser. Their use is governed by the specific privacy policies of the publishers which can be accessed directly from their websites.
3) Data Collection and Use
We do not know who you are. We only collect and use technical data relating to your browsing navigation to display personalized advertisements.
We collect browsing information
Data collected on Zebestof network
To serve relevant ads, we have to be able to single out patterns but we never willingly store data that would allow identification of a person (such as name, surname, phone number, address, etc.). We collect data related to your browsing activity through cookies that record:
- events related to your activity on our advertising partner’s website (such as the number of pages viewed, the products you viewed on the partner website)
- information related to your device (device type, operating system, version)
- non-precise information related to your geography and derived from the truncated IP address of your connection (in order to serve you ads only for products and services available in your country, region or city)
- and events related to the Zebestof ad serving activity such as the number of ads displayed to you.
We also gather certain information automatically. This information may include browser type, referring/exit pages, the files viewed on our site (e.g., HTML pages, graphics, etc.), operating system, date/time stamp, and/or clickstream data to analyze trends and optimize our services.
We do not use or store full IP address for targeting purposes. Your full IP addresses may only be used by Zebestof for the following purposes:
- Fraud detection purposes to help alert us to situations which could not have been caused by human behavior, such as a massive amount of clicking in a limited period of time;
- Sales attribution
- Marketing reports with aggregated data.
We also collect technical user identifiers from our advertising partners for serve you relevant ads based on your behaviour across environments (“ID syncing”). For that purpose we may process and store:
- Zebestof Bestofbidder :
- Technical IDs of our advertising partners, and/or a of your CRM ID or of your email address – we use a double hashing method based on state-of-the art technologies to ensure the non-reversibility of your information. A hash of your email corresponds to a series of characters that does not permit your identification. For example, a hash of firstname.lastname@example.org would be 98307a5ba02fa1072b8792f743bd8b5151360556b8e5a6120fa9a04ae02c88c0.
Data collected from trusted partners
We can collect technical identifiers from third parties for the purpose of improving our ID syncing and offering you a seamless online experience. These trusted partners commit to only sharing ID syncing information that allows us to link users’ cookies and to provide an efficient choice mechanism to end-users (opt-out).
For example, the linking information sourced from our partners could be Cookie ID ABC = MD5 hashed value. Our partners may use probabilistic or deterministic methods but in all cases please note that besides the ID syncing information, no other data (whether personally identifying information or non-personal identifying information) that could be collected by our partners in the course of their services are shared with us. Moreover, we require that all our partners provide users with a simple way to opt out from the collection and use of their data.
We do not collect any identifying information
We do not know who you are. We do not know your address, your place of work, your date of birth, your email address, your phone number.
We do not collect hardware-based identifiers such as UDID or MAC Address.

Aggregated data does not permit identification of a partner and does not permit you to be directly identified. We share non-aggregated data only upon approval of our partners and in compliance with our commercial agreements.

These companies are authorized to use the information we provide only as necessary to provide these services to us.
