iDNES and Partner Sites Offer Targeted Advertising with User Consent The Czech news portal iDNES.cz, along with its sister sites Lidovky.cz, Expres.cz and Antiyoutuber.cz, allows visitors to opt in to targeted advertising by consenting to the use of cookies and other network identifiers. If a user grants this consent, the sites will display both targeted and non‑targeted ads. Targeting is based on profiling of users’ online habits and interests, derived from data collected about their internet activity. The aim is to show advertisements that are relevant to each visitor. Targeted advertising is carried out by MAFRA, a.s. and a network of 125 advertising partners. A list of these partners and additional information is available on the sites’ privacy pages. Users can withdraw their consent for targeted advertising at any time. If they do so, they will be prompted to switch to iDNES Premium, a subscription service that removes all ads. Consent for other purposes—such as displaying content tailored to a user’s interests—can be changed or withdrawn without requiring a subscription. The sites process certain data on the basis of “legitimate interest.” Users who wish to object to this processing or who want to adjust their privacy settings can do so in the “Detailed Settings” section. Settings applied here affect all four sites. Data processing activities include: Using limited data to select advertisements Employing profiles to choose personalized content Creating profiles for personalized content Measuring ad performance Understanding audience through statistics or data combinations from various sources Using profiles to select personalized advertising Developing and improving services Measuring content performance * Technical site operation If a user chooses the free version of iDNES and consents to targeted advertising, the consent applies to the purposes listed above. Due to technical constraints on the advertising providers’ side, users must explicitly indicate their disagreement with certain processing activities—such as using profiles for personalized content, measuring content performance, and technical site operation—within the “Processing by Publisher and Other Partners” section. If a user does not consent to these specific activities, the sites will not carry out that processing. There are a few exceptions. Certain advertising formats, such as commercial messages or self‑promotion by the company and its subsidiaries, are difficult to remove from the content. Details are provided in the sites’ terms of service. Users can set preferences separately for other sites operated by the same company. However, if a user consents to targeted advertising on those sites, the sites will assume that the user has also consented for iDNES.cz, Lidovky.cz, Expres.cz and Antiyoutuber.cz.
