How we use your details.
Who we are
South London Saunas Ltd, trading as HOTDROP, registered in England and Wales, company no. 16276748. We run the sauna and cold plunge at Arch 66, Queen's Circus, Nine Elms, London SW8 4NE. We decide how your details are used, so we are the controller under UK data protection law.
What we collect
- Your name and email and, if you add them, your phone number and birthday.
- Your visits, credits, membership, gifts and the guests you invite.
- That you agreed to the waiver and confirmed you are 18 or over, and when.
- Payments: we see what you paid and when. Card details go to our payment provider, never to us.
- Messages you send us in chat or by email.
- Visits to our site: we count page views with Vercel Web Analytics, which sets no cookies and stores no personal information.
- If you continue with Apple or Google: your name, your email (or Apple's private relay address) and an account id from them. No password, no contacts.
Why
- To run your account and bookings, and email you codes, confirmations and receipts (our contract with you).
- To have everyone confirm they are 18 or over and agree to the waiver (safety, our legitimate interest).
- To keep accounts and payment records (legal obligation).
- To send offers and news, only if you said yes. You can stop them any time from your profile.
