A plain explanation of the information we collect and why. Last updated October 2026.
What we collect
We collect the details you choose to send us: email address, update preferences, preferred area, booking details (name, contact info, event date and place), and, if you make a Madru account, the profile details you add: name, phone, birthday month and day (never the year) and ZIP. For the ServSafe trainer, an email address and saved study progress if you create an account.
How we use it
Update preferences are used to send cart, event, booking, or soft-launch news. Booking details are used to respond to the inquiry and run your event. Account details are used to sign you in and, only if you tick the box for it, send you updates; we keep a record of when you said yes or no. ServSafe account details are used to sign you in and save progress. We do not use a ServSafe account email for Madru marketing unless you separately opt in. We never sell your information.
Where it lives
Email updates are managed through Klaviyo. Accounts, booking details and ServSafe progress are stored in our hosted database (Neon). Booking payments are handled by Square; we never see or store your card number. Service emails, like sign-in codes, are delivered through Resend. We use Vercel Analytics to understand general site activity, without cookies or personal details.
Your choices
Every marketing email includes an unsubscribe option. If you have an account, you can change your details, download everything it holds, or delete it yourself at madru.cafe/account. You can also ask what information we have, correct it, or ask us to delete it by emailing nelly@madru.cafe.
