3. Types of Cookies We Use

Essential Cookies

Essential cookies are required for the operation of the website, ensuring security, enabling login functionality, managing memberships, processing payments, load balancing, and storing user preferences.

Because certain services you request cannot be provided without these cookies, they cannot be disabled.

Under Section 25(2) TDDDG, separate consent may not be required for the use of essential cookies. Personal data associated with these cookies is processed, depending on the nature of the processing, on the basis of Article 6(1)(b) or Article 6(1)(f) GDPR.

Functional Cookies

Functional cookies may help remember choices such as your language or display preferences and may enable additional website features.

To the extent that these cookies are not strictly necessary, they are activated only with your consent.

Analytics Cookies

Analytics cookies may help us understand visitor numbers, which pages are used, and how the website is used.

If non-essential analytics cookies are used on our website, they will only be activated with your prior consent.

Marketing Cookies

Marketing cookies may be used to measure the effectiveness of advertising, display content or advertisements based on interests, and associate visits across different websites.

If marketing or advertising cookies are used on our website, they will only be activated with your prior consent.

4. Our Current Cookie Configuration

The website is currently configured to use cookies that are necessary for the operation of the Wix infrastructure and the features requested by users.

If non-essential analytics, marketing, or tracking technologies are enabled in the future, they will not be activated without prior consent, and the cookie preference panel and this Policy will be updated accordingly.

Up-to-date information regarding the name, provider, purpose, and retention period of the cookies used is displayed in the cookie preference panel.

5. Changing Your Cookie Preferences

You may withdraw your consent to non-essential cookies or change your preferences at any time.

[Open cookie preferences]

Any change to your preferences will apply to future use. Withdrawal of consent does not affect the lawfulness of processing carried out before consent was withdrawn.

Essential cookies cannot be disabled through the cookie preference panel because they are necessary for the basic operation of the website.

6. Browser Settings

You may delete or block cookies through your browser settings or configure your browser to notify you when cookies are placed.

If all cookies are blocked, certain features of the website, including membership, login, payments, appointments, or other website functions, may not operate correctly.

Instructions on how to change cookie settings are available in the help and privacy sections of your browser.

7. Service Providers

Cookies and similar technologies may be used in particular by the following service providers:

Wix Online Platform Limited and Wix group companies: Website infrastructure, security, membership functionality, sessions, file storage, appointments, ticketing, and essential website functions.
Stripe and PayPal: Payment processing, security, and fraud prevention where the user selects one of these payment methods.
Other service providers: Only where the relevant service has been added to the website and, for non-essential processing, the required consent has been obtained.

Some of these service providers may act as independent data controllers in relation to their own services.

8. Retention Periods

Session cookies may be deleted when the browser session ends. Persistent cookies may remain on your device for a specified period where necessary for their intended purpose.

The current retention period for each cookie is displayed in the cookie preference panel. You may also delete cookies earlier through your browser settings.

9. Changes and Contact

This Policy may be updated if the services we use, the cookies placed, or applicable legal requirements change.
