When you make a booking, we collect your name, email address, your preferred way to be contacted (WhatsApp, Instagram or email), date/time, and number of participants. That's all — we do not collect addresses, birth dates, or ID numbers.
Why email is required. Your booking confirmation, receipt, and a private link to view or cancel your booking are sent by email. That link is the only way to reach your booking without contacting us, so we need a working address to send it to. We do not send marketing email.
Card and payment details never touch our systems. When you pay, your card details go straight from PayPal's own payment window to PayPal — they are never sent to, seen by, or stored on our servers. We only ever receive a transaction reference and the amount. Messages sent through the Contact form are delivered directly to us and are not stored on this website.
Only to arrange and run your class: sending your confirmation and receipt, letting you cancel or change your booking, and contacting you about it. We do not send marketing messages, and we never sell or share your information with third parties.
Booking records are kept as required by Korean tax law, then deleted. If you'd like your information removed earlier, contact us and we'll delete it wherever the law allows.
We run this website on services provided by companies outside Korea, so some of your information is processed abroad. Korean privacy law lets us do this without asking for separate consent when the transfer is a processing arrangement we need in order to arrange and deliver the class you booked — as long as we disclose the details below. So here they are, in full.
| Who receives it (contact) | What is transferred | Country | When & how | Why | Kept for |
|---|---|---|---|---|---|
| PayPal (Europe) S.à r.l. et Cie, S.C.A. paypal.com/kr/smarthelp/contact-us |
Payment amount and the card/PayPal details you enter directly in PayPal's own window (we never receive them) | United States, Luxembourg | At the moment you pay, over an encrypted connection | To take payment for your class | Per PayPal's own policy (financial record-keeping) |
| Vercel Inc. privacy@vercel.com |
Your booking form contents, while being sent | United States | Each time you submit a form, over an encrypted connection | To run this website | Not stored — passed straight through |
| Supabase Inc. privacy@supabase.io |
Name, contact, class date/time, party size, payment record | Seoul, South Korea (stays in Korea) | When your booking is created, over an encrypted connection | To store your booking | As required by Korean tax law, then deleted |
| Google LLC support.google.com/policies |
Class photos; enquiry messages | United States | When a photo or enquiry is submitted | Photo board and message delivery | Until you ask us to delete it |
| Telegram FZ-LLC telegram.org |
Your booking details, as a notification to the owner | Outside Korea (UAE) | Immediately after you book | So we see your request straight away | Until the owner deletes the message |
You may refuse this transfer. If you do, we can't take your booking through this website — but you can still book by messaging us directly.
We also use Google Analytics (Google LLC, United States) to count page visits and see which pages are useful. This is not needed to run your booking, so we keep it separate: it never receives your name, contact details or booking — only anonymous usage statistics, with your IP address anonymised.
You can turn it off right here, and we'll respect it immediately. When it's off, the analytics script is never loaded at all — nothing is sent.
Checking…
Your choice is stored in this browser only. We also automatically honour your browser's "Do Not Track" and Global Privacy Control settings — if either is on, we don't load analytics even if you haven't used this button. You can also install Google's opt-out add-on to block it on every website.
You may ask us at any time what information we hold about you, ask us to correct it, or ask us to delete it — just use the contact form.
