1. Introduction
This cookie policy explains which cookies and similar technologies ("cookies") we use on the RU21 GmbH website and online shop, and for what purposes. Cookies help us ensure the technical operation of the website, enable the ordering process, and—only with your consent—analyze our offerings and manage marketing activities. Consent is given exclusively through our consent tool. You can individually consent or decline for each cookie category. There are no default settings. Cookies that are not technically necessary are only set after you actively select the appropriate option.
Data processing is carried out in accordance with the General Data Protection Regulation (GDPR) and – where applicable – Section 25 of the Telecommunications and Digital Services Data Protection Act (TDDDG). We only set cookies that are not technically necessary if you have given your prior consent.
2. What are cookies?
Cookies are small text files that are transferred from our server or a third-party server to your browser and stored on your device. They allow us, for example, to save your shopping cart or to recognize that you have already visited our site.
A distinction is made between session cookies (which are deleted after the browser is closed) and persistent cookies (which remain stored for a defined period of time).
3. Which cookies we use
(a) Technically necessary cookies
These cookies are necessary for our website and especially the online shop to function properly. Without them, we cannot offer essential functions such as shopping cart, checkout, login, or security.
Typical examples (Shopify):
_shopify_s, _shopify_y, _secure_session_id, cart, checkout_token, cart_sig,
as well as cookies to store your cookie settings (cookie_consent, cookie_preferences).
Legal basis: Art. 6 para. 1 lit. f GDPR (legitimate interest in a functioning online shop) or § 25 para. 2 TDDDG (technically necessary).
(b) Functional cookies
These cookies remember your chosen settings (e.g. language, currency, displayed region) and make it easier for you to use our webshop.
Legal basis: Your consent pursuant to Art. 6 para. 1 lit. a GDPR in conjunction with § 25 para. 1 TDDDG.
You can revoke this consent at any time via our cookie/consent tool.
(c) Analytics and statistics cookies
We use these cookies to understand how visitors use our website (e.g., which pages are accessed, how long a visit lasts). This allows us to improve our services. When integrating services from third countries (especially the USA), personal data is only transferred with your explicit consent. There is a risk of a lower level of data protection. If the provider is certified under the EU-US Data Privacy Framework, this will be indicated.
Example: Google Analytics 4 (if activated)
Provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.
The following data, among others, may be processed: pages visited, click paths, approximate location data, browser and device data, referrer URL.
IP addresses can be shortened/anonymized.
Cookies: e.g. E.g. _ga, _gid, _gat.
Legal basis: Your consent pursuant to Art. 6 para. 1 lit. a GDPR in conjunction with § 25 para. 1 TDDDG.
When using Google services, data may be transferred to the USA; Google relies on recognized safeguards for this. When integrating services from third countries (especially the USA), personal data is only transferred with explicit consent. There is a risk of a lower level of data protection. If the provider is certified under the EU-US Data Privacy Framework, this will be indicated.
If Google Analytics is not integrated, these cookies will not be set.
(d) Marketing and tracking cookies
We use these cookies to show you content and advertising tailored to your interests or to measure the success of campaigns (e.g., whether an ad led to a purchase). When services from third countries (especially the USA) are integrated, personal data is only transferred with your explicit consent. There is a risk of a lower level of data protection. If the provider is certified under the EU-US Data Privacy Framework, this will be indicated.
Possible examples (depending on the shop setup):
• Meta Pixel (Facebook/Instagram), Meta Platforms Ireland Ltd., 4 Grand Canal Square, Dublin 2, Ireland
• Google Ads Conversion/Remarketing, Google Ireland Limited
• TikTok Pixel, TikTok Technology Limited
• Pinterest Tag
These services may exchange data with providers in third countries (especially the USA). When integrating services from third countries (especially the USA), personal data is only transferred with explicit consent. There is a risk of a lower level of data protection. If the provider is certified under the EU-US Data Privacy Framework, this will be indicated.
Legal basis: exclusively your consent pursuant to Art. 6 para. 1 lit. a GDPR in conjunction with § 25 para. 1 TDDDG.
These cookies will not be set without your consent.
(e) Third-party cookies / embedded content
When you use third-party features (e.g., embedded videos, payment providers, social media links), these providers may set their own cookies. The privacy policies of the respective providers apply to these cookies. Where possible, we integrate such content in such a way that it is only loaded after your consent. When integrating services from third countries (especially the USA), personal data is only transferred with your explicit consent.
Consent is required. There is a risk of a lower level of data protection. If the provider is certified under the EU-US Data Privacy Framework, this will be indicated.
