Privacy Policy

Last updated: 29 September 2026

1. Introduction

HomeMaster ("we", "us", "our") operates the website homemaster.co and provides home cleaning and aircon servicing in Singapore. This Privacy Policy explains how we collect, use, and protect your personal information.

2. Information We Collect

  • Contact details: Name, phone number, email address
  • Address: Service address and postal code for booking
  • Payment information: Processed securely via Airwallex; we do not store card details
  • Communication preferences: WhatsApp opt-in status
  • Messages: What you write to Helen, our WhatsApp assistant, and the photos or files you send her
  • Booking requests from AI assistants: If an AI assistant (such as ChatGPT or Claude) asks us to book for you, the WhatsApp number, service address, visit and, if given, name it sends us
  • Usage data: Pages visited, booking history, device information
  • Website analytics: Which page you arrived on, how far you got in the booking form, the site that linked you here, and any campaign or referral code in the link

2a. Website Analytics

We measure how our own website is used, using our own systems. We do not use Google Analytics or any other third-party tracking service, we set no advertising cookies, and nothing about your visit is shared with another company for tracking.

What this records is the pages you view on homemaster.co, how far you get in the booking form, the website that linked you to us, and any campaign or referral code that was in the link you followed. It does not record your name, phone number, address or payment details, and it does not follow you to other websites. Your browser remembers which link first brought you here for up to 30 days, so we can tell which of our own pages and partners actually help people. Clearing your browser data removes it.

3. How We Use Your Information

  • Process and manage your cleaning bookings
  • Send booking confirmations, reminders, and updates via SMS or WhatsApp
  • Send one-time verification codes (OTP) for authentication
  • Process payments through our payment provider
  • Improve our services and customer experience
  • Understand which of our pages and referral partners bring us customers

4. WhatsApp & Messaging

If you opt in to WhatsApp notifications, we will send you cleaning reminders and booking updates via WhatsApp. You can opt out at any time by replying "STOP" to any WhatsApp message or toggling the setting in your booking page. We use Meta's WhatsApp Business API to deliver these messages.

4a. AI Assistants and Helen

AI assistants can check our prices and open times, and ask us to book a clean for you. When one does, we send one booking card to the WhatsApp number it gave us. Nothing is booked or charged unless you tap "Yes" and then pay. Your name is saved to your details only if you confirm. We keep a record of the request (the number, address and visit asked for) so the assistant can check its status and so we do not message you twice. When an assistant checks a request, we never give it your personal details.

Helen, our WhatsApp assistant, is an AI. To write her replies, the text of your messages and the booking details needed to answer are processed by AI model providers. Photos and files you send her are read the same way. Questions that AI assistants send us are answered the same way too. These providers do not receive your payment details.

5. Data Sharing

We do not sell your personal data. We share information only with:

  • Service providers: Assigned cleaning professionals (name, address, booking details)
  • Payment processors: Airwallex for secure payment processing
  • Communication platforms: Twilio (SMS), Meta (WhatsApp) for notifications
  • AI model providers: DeepSeek and Moonshot AI (Kimi), to write Helen's replies and read the photos and files you send
  • Infrastructure: Supabase (database), Vercel (hosting), Sentry (error tracking)

6. Data Security

We implement appropriate security measures to protect your data, including encryption in transit (HTTPS/TLS), secure authentication, and role-based access controls. Payment data is handled by PCI-compliant processors.

6a. How Long We Keep Data

We keep your details, bookings, payments and messages while you use HomeMaster, and after that for as long as we need them for accounting, tax and legal reasons. You can ask us to delete your data at any time, as our data deletion page explains. We then delete it, or anonymise it where we can, except for records the law requires us to keep.

7. Your Rights

You may request to access, update, or delete your personal data at any time by contacting us. You can opt out of marketing communications and WhatsApp notifications at any time.
