Google AdWords and Google Conversion-Tracking


This website uses Google AdWords. AdWords is an online advertising program of Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States ("Google").

In the context of Google AdWords we use the so-called conversion tracking. When you click on an ad placed by Google, a cookie is set for conversion tracking. Cookies are small text files that the Internet browser stores on the user's computer. These cookies expire after 30 days and are not used to personally identify users. If the user visits certain pages of this website and the cookie has not expired, Google and we may recognise that the user has clicked on the ad and been redirected to that page.

Each Google AdWords customer receives a different cookie. Cookies cannot be tracked through the websites of AdWords customers. The information collected through the conversion cookie is used to compile conversion statistics for those AdWords customers who have opted-in to conversion tracking. The customers will know the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag. However, they do not receive any information that can be used to personally identify users. If you do not wish to participate in tracking, you can opt-out of such use by simply turning off the Google conversion tracking cookie on your web browser under User Preferences. You will then not be included in the conversion tracking statistics.

The website operator has a legitimate interest in the analysis of user behaviour in order to optimise both his website and his advertising.

You can find more information about Google AdWords and Google Conversion Tracking in the Google data protection regulations:

You can set your browser to inform you when cookies are set and to allow cookies only in individual cases, to exclude the acceptance of cookies for certain cases or in general, and to activate the automatic deletion of cookies when the browser is closed.

Processing of personal data by aleno


These terms and conditions apply to the rental of hotel rooms and all related services. The terms and conditions of Seehotel Kastanienbaum apply exclusively. The customer's terms and conditions shall not become part of the contract even if they have not been expressly contradicted. 

In order to accept and manage online reservation requests through our website, we use the restaurant management system aleno, offered by aleno AG based in Switzerland. The use of aleno allows us to electronically collect personal information about our guests ("Guest Data"). The guest data includes the following information:

First and last name
Telephone number and email address
Number of persons, time and date of desired visit
Home address (optional)
Company name (optional)

The collection of guest data allows us to process your reservation request and ensure that the table you requested is reserved in your name and that we can contact you if necessary. The legal basis for the use of aleno for electronic reservation is based on our legitimate interests according to Art. 6 Para. 1 lit. f GDPR. The guest data we collect will not be automatically deleted after the reservation is made but will be used to create a personal guest profile. For more information on the guest profile, please see section […] below. You have the right to request deletion of your guest data at any time. If the deletion occurs before the reservation date, the corresponding reservation will be automatically canceled.

The guest data collected for the acceptance and execution of an online reservation is used by us to create a personal profile for our guests in the restaurant management system aleno ("guest profile"). This enables us to use the guest data to personalise our services. After your visit to our restaurant, we reserve the right to add further personal data to the guest profile to enable us to personalise it further ("profile data"). This profile data is the following information: Personal Data to personalise Guests, including preferred language, allergies and special requests, birthday, customer category and status. Information about past restaurant visits, including time and date of visit, length of stay, number of guests, type and location of table, amount spent and any no-shows. Consolidated information on all restaurant visits to date, including total number of visits, total amount spent and total number of no-shows. 


Reservation requests are binding only after we have confirmed the table, date and original time by e-mail or telephone.

Collection of credit card information for reservations

Online reservation requests are only binding once we have confirmed the table, date, and time by email or phone. To ensure that we do not incur any damages in case of an unexcused no-show, we reserve the right to require a credit card as a payment guarantee. In doing so, we collect the following information ("Payment Information"):

Name of the credit card issuer
Name of the credit card holder
Expiration date of the credit card
Credit card number and verification code

If you provide your payment information when making an online reservation request, aleno automatically anonymizes the information. This means that the payment information does not constitute personal data within the meaning of the Swiss Data Protection Act (DSG) or the EU General Data Protection Regulation (GDPR). The payment information is also transmitted directly to the hosting provider of aleno AG. We therefore do not have access to the anonymized payment information and do not store it on our system.

Cancellation or No-show

Charges for cancellation or no-show may be incurred up to the amount of the agreed charges after the relevant time and will be charged in the agreed amount of the payment method specified at the time of booking.

Changes or Cancellations by Us

If it was agreed when booking the table that you can cancel the contract free of charge within a certain period of time without giving any reason, we are also entitled to cancel the contract within this period of time (e.g. if contractually agreed advance payments are not made). In the event of a justified cancellation on our part, you shall not be entitled to any compensation.

Force Majeure

We are not liable and will not pay any compensation if the fulfilment of our obligations is directly or indirectly prevented or impaired by or as a result of force majeure or other circumstances beyond our reasonable control, in particular in relation to flooding, earthquakes, extremely adverse weather conditions, natural disasters, pandemics, natural events, terrorist acts, fire or failure of electricity, gas, water or other supply services, facilities, machinery, computers, vehicles or building collapses, and provided that we have not acted negligently or recklessly in any way.


The creation of a guest profile and the collection of profile data enables us to tailor our services to you and thereby ensure that you feel at home with us and that we can cater to your individual needs. The legal basis for the use of aleno to create a guest profile is the protection of our legitimate interests pursuant to Art. 6 para. 1 lit. f DSGVO. The guest data and profile data contained in the guest profile are deleted or anonymised as soon as they are no longer used for their original purpose. You have the right to request deletion of your guest profile and the guest data and profile data contained therein at any time. 


When collecting and processing guest data, payment information and profile data in connection with the use of the restaurant management system aleno, we are deemed to be the controller within the meaning of Art. 4 No. 7 DSGVO, which decides on the purposes and means of processing the personal data collected and is responsible for ensuring and fulfilling the rights of the data subjects. The guest data, payment information and profile data are transmitted to and processed by aleno AG after they have been collected. aleno AG qualifies as a processor within the meaning of Art. 4 No. 8 DSGVO, which processes personal data on behalf of the controller. For this reason, we have concluded a contract with aleno AG for commissioned data processing and thus fully implement the requirements of the DSGVO when using aleno.
Further information on the collection and handling of your personal data in connection with the use of aleno can be found in the data protection declaration of aleno AG, which can be accessed via the following link:
