1. Access to our website
When you visit our landing page, information is automatically transmitted from your browser to our server. This data is technically necessary to display the website correctly and to ensure stability and security.

The following data is processed:

• IP address (anonymized where technically possible)
• Date and time of access
• Name and URL of the file accessed
• Website from which access is made (referrer URL)
• Browser type, browser version, and operating system

This data is used solely to ensure operation and for error analysis.
Legal basis: Art. 6 para. 1 lit. f GDPR (legitimate interest in a secure and functioning website).

2. Cookies and consent management
We use cookies and similar technologies. Some are technically necessary to operate the site. Others – such as analytics or marketing cookies – are only used with your consent.

On your first visit, a consent banner appears where you can make your choice.

3. Necessary technologies
To ensure the site works and displays properly, we use among others:

• Tailwind CSS (served locally)
• Font Awesome (served locally)
• Google Fonts (served locally, no connection to Google servers)

These assets are loaded only from our server, so no personal data is transferred to third parties.
Legal basis: Art. 6 para. 1 lit. f GDPR (legitimate interest in a user-friendly website).

4. Contact form
When you send us inquiries via the contact form, the information you provide (name, email address, subject, message) is stored for the purpose of processing the request and in case of follow-up questions.

The processing of this data takes place solely on the basis of your explicit and voluntary consent (Art. 6 para. 1 lit. a GDPR), which you give by clicking the checkbox and submitting the form.

You can withdraw this consent at any time. A simple email to us is sufficient. The legality of the data processing carried out until the withdrawal remains unaffected.

We store the data you enter in the contact form until you ask us to delete it, revoke your consent, or the purpose for data storage ceases to apply (e.g., after your request has been processed). Mandatory statutory provisions – in particular retention periods – remain unaffected.

5. Analytics tools
Google Analytics
With your consent we use Google Analytics, a web analytics service provided by Google Ireland Limited.

Google Analytics uses cookies that allow us to analyze the use of our website. The data may be transferred to servers in the USA. We use Analytics exclusively with IP anonymization so that your IP address is shortened within the EU/EEA.
Legal basis: Art. 6 para. 1 lit. a GDPR (consent).

6. Marketing
Meta Ads (Meta Pixel)
With your consent we use the Meta Pixel (Facebook/Instagram Ads), provided by Meta Platforms Ireland Limited.

The pixel helps us measure the success of our ads and build audiences for future campaigns. Data may be transferred to the USA. Meta is certified under the EU-U.S. Data Privacy Framework.
Legal basis: Art. 6 para. 1 lit. a GDPR (consent).

Conversion tracking on purchase pages (current technical implementation: Google Analytics, Google Ads and Meta Pixel)
On pages with a purchase option (e.g. the city pass), with your consent to “Analytics” we record the start of checkout as a begin_checkout event and, after server-side confirmation of payment, a purchase event in Google Analytics. With your consent to “Advertising”, clicking “Book Now” sends a checkout conversion to Google Ads as well as the Meta standard event InitiateCheckout. After confirmed payment, we also send a separate purchase conversion to Google Ads and the Meta standard event Purchase.

Google Ads receives a random, non-secret transaction ID generated in the browser to prevent duplicate counting, as well as purchase value and currency; Google Analytics and Meta additionally receive product ID and product name. The Stripe session ID and voucher code are not sent to Google or Meta. To associate the purchase after returning from the payment provider, we store this tracking context for up to seven days in session storage, local storage and a first-party cookie where consent has been given. Without the respective consent, the relevant tags are not loaded, no tracking context is created and no events or cookieless pings are sent to Google or Meta.
Legal basis: Art. 6 para. 1 lit. a GDPR (consent).

• Correction of inaccurate data (Art. 16 GDPR)
• Deletion (Art. 17 GDPR)
