Cookie Policy

Effective: September 27, 2026  |  Version: 1.1

1. What Is a Cookie?

A cookie is a small text file that the website you visit places on your device (computer, mobile phone, tablet) through your browser. Cookies allow the website to recognize returning visitors, remember user preferences, and collect statistical data on how the site is used.

Cookies do not contain executable program code, do not spread viruses, and cannot by themselves collect personal data; they only come into contact with personal data if the user provides it directly through one of the website's own interfaces. In the European Union, the placing of cookies is regulated under the ePrivacy Directive and the GDPR.

2. What Cookies Do We Use?

a) Necessary and functional cookies
These cookies are essential to the basic operation of the website. Without them, certain features of the site, such as session handling and the correct functioning of forms, would not be available. These cookies do not require prior consent, since under the Electronic Communications Act they are strictly necessary in order to provide the service.

  • Session cookie: Active for the duration of your visit to the site; it is automatically deleted when you close your browser. Its purpose is to ensure a consistent browsing experience.
  • CSRF token: A security token used to protect form submissions against forgery. It lasts until the end of the session.
  • Campaign Detective login (adverr_nyomozo): Identifies the user logged in to Campaign Detective, so they do not have to log in again on every page. It lasts 7 days and is deleted on logout.

b) Analytics cookies
Analytics cookies collect anonymous statistical data on how visitors use our website, which pages they visit, how much time they spend there, and what source they arrive from. The data is processed in aggregated form, in a manner unsuitable for identifying individuals. Placing analytics cookies requires your prior consent.

  • Google Analytics (_ga, _gid, _gat): A web analytics service operated by Google LLC. IP anonymization is enabled; the data may also be transferred outside the European Economic Area, but Google ensures an adequate level of protection under the Google Standard Contractual Clauses.

c) Marketing and remarketing cookies
Marketing cookies are used to track visitors' interests and online behavior, so that we can show them relevant advertisements on other websites and platforms. Placing these cookies requires your explicit, prior consent.

  • Meta Pixel (_fbp, _fbc): A conversion-tracking and remarketing tool of Meta Platforms Ireland Ltd. It records visitor activity on the website and enables the display of targeted advertisements on the Facebook and Instagram platforms.
  • Google Ads remarketing (IDE, _gcl_au): A remarketing cookie of Google's advertising platform, which lets us show targeted advertisements to our previous visitors on the Google Display Network and on YouTube.

3. Managing Cookies

Most browsers accept cookies by default, but you can change this at any time in your browser's settings. You will find instructions for the most popular browsers at the links below:

  • Google Chrome
  • Mozilla Firefox
  • Apple Safari
  • Microsoft Edge

Please note that disabling cookies may affect the availability of certain features of the website and the quality of the user experience.

4. Managing Consent

The first time you visit our website, a cookie notice banner appears, where you can freely decide whether you consent to the placing of analytics and marketing cookies. Necessary/functional cookies remain active regardless of consent, since they are essential to the operation of the site.

You may withdraw your consent at any time through your browser's cookie management settings, or by sending a request to info@adverr.hu. Withdrawal does not affect the lawfulness of processing based on consent given before the withdrawal.

5. Third-Party Cookies

The analytics and marketing providers listed above (Google, Meta) also process certain data as independent data controllers, under their own privacy policies. adverr™ has no direct influence over that processing. The privacy notices of these third-party data controllers:

  • Google: policies.google.com/privacy
  • Meta: facebook.com/privacy/policy
