PRIVACY POLICY

Effective Date: January 2026

At MAISON RARE WINES, operated by Da Costa Strategic Partner, we recognize that absolute privacy, discretion, and confidentiality are paramount for our global clientele. This Privacy Policy outlines how we collect, protect, and handle your information within our off-market fine wine and spirits intermediation ecosystem. 

1. Data Collection & Purpose

• Identification Data: Name, professional contact details, jurisdiction, and corporate background.

• Verification Documents: Identity verification and Proof of Funds (POF), as required by Swiss Anti-Money Laundering (AML) standards and "Know Your Customer" (KYC) compliance frameworks.

• Acquisition/Divestment Criteria: Specific requirements regarding fine wine allocations, preferred terroirs, vintage profiles, target budgets, and cellar specifications.

2. Absolute Confidentiality & Data Sharing

Under no circumstances do we sell, rent, trade, or publicly expose your personal or portfolio data. Your information is shared strictly under the following conditions:

• Explicit Consent: When introducing your verified buying criteria or off-market cellar assets to a pre-qualified counterparty (Buyer/Seller) within the scope of a formal Bespoke Mandate.

• Legal Compliance: When strictly required by Swiss federal legislation or Swiss judicial authorities.

• Third-Party Advisors: With trusted legal, logistical, or professional authentication experts (e.g., bonded warehouse managers, temperature-controlled transit specialists, oenological appraisers) necessary for the execution of a transaction—always bound by strict Non-Disclosure Agreements (NDA).

3. Secure Communication & Storage

Due to the highly sensitive nature of high-value liquid asset transactions and off-market portfolio transfers:

• We utilize encrypted channels for the exchange of sensitive documentation, cellar manifests, and compliance records.

• All digital data is hosted on secure servers benefiting from the robust legal protections and regulatory oversight of the Swiss Jurisdiction.

• We enforce zero public indexing: your assets or identity will never leave a digital footprint on open web portals or social media channels.

4. Data Retention

We retain your personal information and portfolio documentation only for as long as necessary to fulfill the operational requirements of your mandate, or as mandated by Swiss statutory record-keeping obligations. If a transaction inquiry does not materialize into a formal mandate, your sensitive data is permanently and securely purged from our active files. 

5. Your Rights

Under Swiss privacy frameworks, you maintain full authority over your data. You have the right to request access to the personal data we hold, request rectifications, or demand the deletion of your records, subject to binding contractual and legal retention duties. 

6. Cookies & Analytics

Our web platform operates with a minimal digital footprint. We utilize essential, non-intrusive cookies strictly necessary for technical site functionality and anonymous traffic analytics. We do not use third-party advertising trackers, remarketing pixels, or public marketplace scripts. 

7. Contact for Data Privacy

For any inquiries regarding your data or to exercise your privacy rights, please contact the management of Da Costa Strategic Partner directly through our secure inquiry forms.

Formal mandates are initiated following a preliminary compliance review . 

Maison Rare Wines is a discreet oenological bridge. We do not maintain a public inventory. We manage mandates.
