Cookie Policy

Last updated: 10 September 2026

This Cookie Policy explains how Zelia uses cookies and similar technologies when you visit our website or use web-based services associated with Zelia.

This Policy should be read together with our Privacy Policy, which provides further information about how we process personal data.

1. What Are Cookies?

Cookies are small text files that may be stored on your device when you visit a website.

They can be used for various purposes, such as keeping you logged in, remembering preferences, maintaining security, storing consent choices or understanding how a website is used.

In addition to traditional cookies, websites may use similar technologies, including:

Local Storage;
Session Storage;
browser-based identifiers;
pixels or similar tracking technologies; and
other technologies that store information on or access information from your device.

Where this Cookie Policy refers to "cookies", this generally includes comparable technologies where applicable.

2. How Zelia Uses Cookies

Zelia may use cookies and similar technologies to operate, secure and improve our website and related services.

Depending on the features currently available on the website, cookies may be used for purposes such as:

providing essential website functionality;
maintaining user sessions;
authenticating users;
protecting accounts and services against abuse;
remembering user preferences;
storing your cookie and privacy choices;
improving website performance; and
analysing website usage, where you have given the required consent.

We do not use optional cookies or similar technologies that require your consent before you have made an appropriate choice through our consent mechanism.

3. Strictly Necessary Cookies

Strictly necessary cookies are required for the website or a feature explicitly requested by you to function correctly.

These cookies may, for example, be used for:

authentication and login sessions;
account security;
fraud and abuse prevention;
load balancing;
essential technical functionality;
remembering privacy or cookie preferences; and
maintaining an active session.

Where the legal requirements are met, these technologies may be used without your prior consent because they are strictly necessary to provide a service you have expressly requested or to perform the transmission of communications.

Where personal data is processed through such technologies, the applicable legal basis depends on the specific processing activity and is described in our Privacy Policy.

Strictly necessary cookies cannot always be disabled through our cookie settings because doing so could prevent essential parts of the website from functioning.

You may still be able to block them through your browser settings, although this may cause parts of Zelia to stop working correctly.

4. Preference Cookies

Preference cookies allow a website to remember choices you have previously made.

These may include, for example:

language preferences;
interface settings;
display preferences; or
other personalised website settings.

Where such cookies are not strictly necessary for a service explicitly requested by you, they will only be used after the required consent has been obtained.

5. Analytics Cookies

Analytics technologies may be used to understand how visitors interact with our website.

Depending on the services used, this may include information such as:

pages visited;
approximate visit duration;
interactions with website elements;
browser and device information;
referring pages; and
technical performance information.

Where analytics technologies require access to or storage of information on your device, they are only activated after you have given the necessary consent.

If analytics services process personal data, such processing is based on the applicable legal basis described in our Privacy Policy.

You may withdraw your consent at any time.

6. Marketing and Advertising Cookies

If Zelia uses marketing, advertising or cross-service tracking technologies in the future, such technologies will only be activated where the required consent has been obtained.

These technologies may be used to:

measure advertising performance;
determine whether campaigns are successful;
personalise advertising; or
recognise users across websites or services.

Zelia will not activate consent-requiring marketing technologies before the user has made an appropriate consent choice.

7. Third-Party Services

Some website features may depend on services provided by third parties.

These providers may use cookies or similar technologies when their services are integrated into our website.

Depending on the services used, this may include, for example:

authentication providers;
payment providers;
content delivery services;
security providers;
analytics providers; or
embedded external content.

Where a third-party technology is not strictly necessary and requires consent, it will only be activated after the appropriate consent has been provided.

Third-party providers may process information under their own privacy policies and terms.

Further information about specific third-party providers and the processing of personal data can be found in our Privacy Policy.

8. Cookie Consent

When you first visit our website, you may be presented with a cookie consent interface where required.

You can use this interface to decide whether optional cookies and similar technologies may be used.

Where applicable, you can:

accept optional cookies;
reject optional cookies;
select individual cookie categories; or
change your choices later.

Strictly necessary technologies may remain active even where optional cookies are rejected, as they are required for essential website functionality.

Your consent must be voluntary and can be withdrawn at any time with effect for the future.

Withdrawing consent does not affect the lawfulness of processing carried out before the withdrawal.

9. Changing or Withdrawing Your Consent

You can change or withdraw your cookie choices at any time through the Cookie Settings available on our website, where such settings are provided.

You may also delete or block cookies through your browser.

Please note that browser settings affect cookies stored through your browser and may not necessarily control every type of storage technology used by websites.

Disabling strictly necessary storage may result in certain website features no longer functioning correctly.

10. Cookie Duration

Cookies may be either session cookies or persistent cookies.

Session cookies are generally deleted when you close your browser or when your session ends.

Persistent cookies may remain on your device for a defined period or until you delete them.

The exact storage duration depends on the purpose of the respective cookie.

Where applicable, information about specific cookie durations is provided through our cookie consent interface or associated settings.

We aim to retain cookies only for as long as reasonably necessary for their intended purpose.

11. Current Cookies and Technologies

The exact cookies and similar technologies used by Zelia may change as our website and services are developed.

Where required, our cookie consent interface provides information about the technologies currently in use, their purpose, category, provider and storage duration.

We do not intentionally classify optional tracking or analytics technologies as strictly necessary in order to bypass consent requirements.

12. Browser Controls

Most browsers allow you to control cookies through their settings.

Depending on your browser, you may be able to:

view stored cookies;
delete individual or all cookies;
block cookies;
block third-party cookies; or
configure how websites are allowed to use cookies.

Please consult the privacy or cookie settings of your respective browser for further information.

Blocking all cookies may negatively affect the functionality of Zelia and other websites.

13. Legal Basis

The storage of information on your device or access to information already stored on your device is carried out in accordance with the applicable provisions of the German Telecommunications Digital Services Data Protection Act (TDDDG).

Where consent is required, we request it in accordance with Section 25(1) TDDDG in conjunction with the requirements of the General Data Protection Regulation (GDPR).

Where storage or access is strictly necessary to provide a digital service expressly requested by you, the exception under Section 25(2) TDDDG may apply.

Where the use of cookies or similar technologies also involves the processing of personal data, the processing is carried out on an appropriate legal basis under Article 6 GDPR.

Where processing is based on your consent, the legal basis is generally Article 6(1)(a) GDPR.

Further details regarding the processing of personal data can be found in our Privacy Policy.

14. Your Data Protection Rights

Where cookies or similar technologies involve the processing of personal data, you may have rights under applicable data protection law.

Depending on the circumstances, these may include rights regarding:

access to your personal data;
rectification;
erasure;
restriction of processing;
data portability;
objection to certain processing activities;
withdrawal of consent; and
lodging a complaint with a competent supervisory authority.

Further information about these rights and how to exercise them can be found in our Privacy Policy.

15. Changes to This Cookie Policy

We may update this Cookie Policy where necessary, for example if:

we introduce new website features;
we change the technologies used on our website;
we add or remove third-party services; or
legal or regulatory requirements change.

The current version will always be published on our website.

The date of the most recent revision is shown at the beginning of this Policy.
