This Cookies Notice is an integral part of the Data Privacy Policy for KS-TF AG (hereinafter referred to as “KS-TF” or “we”). In this notice, we provide you with information about how we use cookies and similar tracking technologies on our websites and their subdomains (hereinafter referred to as “Website” or “Websites”) and how you can manage your preferences.

What are cookies?

Cookies are small text files that are placed on your device (computer, tablet, smartphone) when you visit a website. They are widely used to make websites function more efficiently and to provide information to website owners. Cookies can be temporary (session cookies) or remain on your device for a set period (persistent cookies).

How do we use cookies?

We use cookies for two purposes: some are strictly necessary for our Websites to operate, and others help us understand how visitors use our Websites so that we can improve them. Performance cookies are only set with your consent.

What are your cookie preferences?

When you first visit our Websites, a cookie banner allows you to accept or decline non-essential cookies. You can change your choice at any time through the cookie settings on our Websites. Most web browsers also allow you to control cookies through their settings. You can:

Accept all cookies.
Decline all cookies.
Delete cookies stored on your device.

What type of cookies do we use?

Strictly necessary: Strictly necessary cookies allow core website functionality such as user login and account management. The website cannot be used properly without strictly necessary cookies.
Performance: Performance cookies are used to see how visitors use the website, e.g. analytics cookies. They use randomly generated identifiers rather than your name or contact details, and are only set with your consent.

The table below describes all the cookies used on our Websites, including the name, type, expiry and purpose of each cookie.

What are third-party cookies?

Cookies placed by the operator of this website are referred to as “first-party cookies”. Cookies placed by parties other than the operator of this website are referred to as “third-party cookies”.

We use a trusted payment service provider, Stripe, to process payments. Where you initiate a subscription, Stripe loads payment components into our website from domains under its control. In doing so, Stripe may place third-party cookies on your device or use similar technologies for the purposes of processing your payment securely and of detecting and preventing fraud. Such cookies are strictly necessary for the provision of the payment service you have expressly requested. The processing of personal data by means of these cookies is governed by Stripe’s Cookie Policy and Privacy Policy, which we recommend you review.

How to manage your cookies

When you first visit our Websites, a cookie banner allows you to accept all cookies, decline all non-essential cookies, or click ‘Show details’ to choose which categories to allow. To change your preferences at any time, reopen the cookie settings via the settings icon, click ‘Show details’, switch each category on or off, and click ‘Save & Close’.

Most browsers also allow you to manage whether and how cookies are set, to block cookies on a site-by-site basis, and to clear cookies and browsing data.

We reserve the right to apply any amendments to this notice. Any amendments will be effective immediately upon us posting the updated Cookie Notice on our Websites. Users of our Websites waive the right to receive specific notice about such amendments.
