6. Disclosure abroad
Disclosure abroad only takes place if the state concerned ensures adequate protection (list of states of the FDPIC; the EU/EEA are deemed adequate) or if appropriate safeguards exist (e.g. standard contractual clauses, Swiss-U.S. Data Privacy Framework for the USA).
7. Retention
We retain personal data only for as long as necessary for the purposes or as required by statutory retention periods (in particular Art. 958f CO – ten years for business records). Afterwards, the data is deleted or anonymised.
8. Your rights
You have in particular the right to information (Art. 25 revFADP), rectification, erasure/destruction, objection to certain processing operations as well as the right to the release/transfer of your data (Art. 28 revFADP). You can revoke consents granted at any time. Contact: office@shopperstars.com.
9. Supervisory authority
The competent supervisory authority is the Federal Data Protection and Information Commissioner (FDPIC), Feldeggweg 1, 3003 Bern, www.edoeb.admin.ch.
10. AI product advisor “Professor Nuno”
On the website we offer an AI chatbot (“Professor Nuno”) for product advice. When you use the chat, your inputs are transmitted to Anthropic, PBC (San Francisco, USA) to generate the response and are processed there. Use is voluntary; please do not enter any sensitive personal data in the chat. Disclosure to the USA is based on appropriate safeguards (standard contractual clauses).
11. Online appointment booking (consultation)
On our “Consultation” page you can choose a slot for a personal consultation yourself, using an embedded booking form. The form comes from our group’s appointment system (Odoo, operated on Odoo.sh in the EU) and is embedded in the page. In the process your IP address and cookies that are technically necessary for the booking (session, language selection) are processed.
When you book an appointment, we process your name, your e-mail address, your telephone number, the selected slot and any optional information you provide in the form. The purpose is to arrange, hold and follow up the consultation, including the confirmation and reminder e-mail.
The appointment is added to the work calendar of the person advising you, which is kept in Microsoft 365 (Outlook). The recipients in this respect are Microsoft Ireland Operations Ltd. and, if you book an appointment with a person from NUI – Genossenschaft für Gesundheit und Wohlbefinden eG, that cooperative in Austria. Austria has an adequate level of data protection; transfers to the USA are based on standard contractual clauses or on certification under the EU-U.S. Data Privacy Framework.
We delete the appointment data as soon as it is no longer required for the consultation and its follow-up and no statutory retention obligations apply. You can cancel a booked appointment at any time, informally, by e-mail or by telephone.
12. Data security
We take appropriate technical and organisational measures, including SSL/TLS encryption.
13. Advertising to existing customers
If you have purchased a product from us, we use the e-mail address you provided to inform you about our own similar products – for example with a reminder when your supply is calculated to be running low.
The basis is our overriding interest in informing existing customers about our own similar products (Art. 31(2) revFADP) within the framework of Art. 3(1)(o) of the Federal Act against Unfair Competition (UCA).
You can object to this use at any time – via the unsubscribe link in every e-mail or informally to hello@nui-vital.ch. This is free of charge for you. After an objection, we will no longer use your address for advertising; the processing of existing orders remains unaffected.
Storage period: We use the address for this purpose as long as the customer relationship exists, but no longer than three years after your last purchase.
Processor: The e-mails are sent via Klaviyo (Klaviyo Inc., Boston, USA); see section 5 for details.
14. WhatsApp newsletter and contact via WhatsApp
Our WhatsApp channel (+43 660 6536947) is operated by our partner company, NUI – Genossenschaft für Gesundheit und Wohlbefinden eG, Schulgasse 70, 6850 Dornbirn, Austria, also for customers in Switzerland. It is responsible for processing in this channel; contact: hello@nui-vital.com. Austria ensures adequate data protection.
You subscribe to the WhatsApp newsletter by sending a keyword (e.g. “START”) and then confirming your subscription (double opt-in). The basis is your consent; you can unsubscribe at any time with “STOPP”. If you write to us with a question or with “PARTNER”, we process your message in order to reply to you or to prepare a possible partnership.
We process your phone number, WhatsApp profile name, content and time of the messages, time and source of the subscription, country, subscription and unsubscription status, delivery and read receipts and any information provided voluntarily. For this we use Superchat (SuperX GmbH, Berlin; storage in Germany) and the WhatsApp Business Platform of Meta (Meta Platforms Ireland Limited). Meta retains messages for up to 30 days for delivery and may also process data in the USA; disclosure is based on the Swiss-U.S. Data Privacy Framework or standard contractual clauses.
We store newsletter data until you unsubscribe and keep proof of consent and unsubscription for a further three years. We delete conversation histories as soon as they are no longer needed and no retention obligations apply.
