Your booking
We collect the date, time, party size, first and last name, telephone number, email, the postal address provided and your optional message. The team uses these details to prepare your visit, contact you and handle changes and cancellations. Contact details entered in the form or in the private part of the conversation are not sent to the AI service.
Who receives the information?
Only authorised team members and service providers needed to operate the website have access for their respective tasks. Hosting: Infomaniak, CH. Actual providers and processing locations must be specified below.
Booking emails are sent through Infomaniak. Recipients include the guest and, for alerts, the team. Details of this processing: To be completed by the operator.
How long we keep your data
You can request deletion of your data by contacting our team by email at info@hconcept.ch or by phone on +41 78 308 74 96.
Hosting backups follow this policy: To be completed by the operator. After a restoration, expired data must be removed before service resumes. Deleting data on the website does not recall messages already received in email inboxes.
The AI personal assistant is optional
To choose your evening, your messages, recent conversation history and booking criteria are sent to Google Gemini. Do not enter contact details or sensitive information during this stage. Once the evening is selected, the website collects your contact details in a private part of the conversation: these replies are not sent to the AI service. You then check the summary and personally confirm submission to the booking server. You can also book without AI using the calendar. Email addresses and phone numbers detected in these messages are masked before transmission; this filter does not make the conversation anonymous.
The conversation stays in our server’s memory and expires after 30 minutes of inactivity; it is deleted on restart. The Gemini API is used through a Google project with active billing. Under the paid service terms, Google does not use messages and responses to improve its products, but may log them for a limited period for security. The Google project’s terms apply; OpenAI retention periods are not assumed.
Google is an international service provider; processing outside Switzerland, including in the United States, is possible. The transfer safeguards actually adopted for the Google project are: To be completed by the operator.

Chat with the team
If you ask to speak with the team, your visible chat history and chosen date, time and group size are shared with them. These conversations are stored on this server for 30 days, then deleted automatically. They are not sent to the AI service by default.
Translation is optional. If enabled in the chat, selected messages are sent to the configured AI service, currently Google Gemini. Email addresses and telephone numbers are masked before sending; other information you write, including allergy details, may be shared. You can disable this option at any time. The team reviews replies before sending them.
Cookies and website functions
The website remembers your language and uses a temporary session for your personal assistant and team access. Your IP address is used to limit abusive attempts; expired counters are periodically deleted. This version includes no advertising or audience analytics tools. Technical hosting logs follow the hosting provider’s stated policy. Changes to team accounts are logged for 90 days with the account identifiers involved, the date and the type of change, without passwords.
On-site items
The team records items on a tab linked to your booking. The Cristal QR and your table’s four-digit code open access without entering a name. A technical cookie keeps access for up to 12 hours, limited to the evening. After checking the displayed items, you can finish ordering and pay the tab directly. This blocks additions for the whole group. You can also request a check by the team and receive an invoice after review. For online payments, Stripe handles card or TWINT payment. The site keeps the amount, date and payment reference without storing card details. Invoice requests are sent to the team, which handles them in Bexio. Items and operations are recorded to check the tab. This service sends no data to AI.
Invoicing with Bexio
When Bexio is connected, the team can transfer a closed tab to prepare your invoice. The billing contact selected in Bexio, served items, quantities and amounts are used for this purpose. The team checks and sends the invoice from Bexio.
Your rights
For access, correction or deletion of your information, contact info@hconcept.ch. We may verify your identity and take applicable retention obligations into account. A booking does not subscribe you to a newsletter.
