Privacy Policy

Personal information on this site is whatever you send us when you write in — usually just a name and an email, sometimes a phone or shipping address if you're placing an order. We keep it private and we keep it minimal. We never share it with advertising networks, social platforms, analytics services, or data brokers. Internally only people who need to see it to answer your message can access it. We hold inquiry data for about a year and order data for the legal accounting period (six years in most jurisdictions). You're entitled to ask us what we have, get it in a portable format, correct it, or have it deleted; just email and we'll act within thirty days. If you ever have a concern about how we've handled your information, you can also contact your local data protection authority.

Your information

You're entitled to see, change, or delete any personal data we hold about you. You can also ask us to export it in a portable format (typically a CSV or JSON file), or to restrict how we process it. Send us a note and we will respond within thirty days. We do not charge a fee for this. If you believe we have mishandled your data, you may also complain to the data-protection authority in your country.

Cookies

This site relies on essential cookies for basic functionality: keeping you logged in, remembering cart contents, storing your language and consent preferences. We do not load analytics platforms, advertising tags, or social-media tracking pixels. We do not share browsing data with any third party. Cookies expire either at session end or after a year for the preference store. You can disable cookies in your browser and the site will still load — though features like remember-me, cart persistence, and language selection won't survive across visits.
