**Great Harmony Food Service Limited** ("we", "us") operates the school lunch ordering service at hkjslunch.com for Hong Kong Japanese School, and the WhatsApp customer service line +852 9862 0726. This policy explains what personal data we collect, why, how long we keep it, and how to ask us to delete it.

 

Last updated: 14 October 2026

 

## What we collect

 

When a parent or guardian registers and orders, we collect:

 

- **Account details:** name, email address and phone number.

- **Student details:** each child's name and class, provided by you so meals can be prepared and delivered to the right classroom.

- **Order details:** the dates ordered, the menu chosen for each date, rice portion and the order total.

- **Payment records:** the payment reference and any receipt image you upload as proof of transfer. We do not collect or store card numbers or bank login details.

- **Customer service messages:** if you contact us on WhatsApp or by email, the content of those messages, your WhatsApp display name and phone number, so our customer service team can answer you and keep a record of what was agreed.

- **Usage records:** a log of key actions on the ordering pages (for example order submitted, payment proof uploaded, errors), used to fix problems and to settle questions about whether an order was placed before the deadline.

 

## Why we collect it

 

- To take, prepare, deliver and bill school lunch orders.

- To confirm payments and resolve payment differences.

- To answer customer service enquiries.

- To meet our record-keeping obligations.

 

We do not sell your personal data and we do not use it for advertising.

 

## Who we share it with

 

- **Our meal preparation and delivery partners:** only what is needed to prepare and deliver the right meals (student name, class, date, menu and rice portion).

- **The school:** where needed to coordinate delivery or resolve an issue about a specific student.

- **Service providers that run our systems:** Wix (website), Supabase (database), Meta Platforms (WhatsApp Business messaging) and Microsoft (email). They process data on our behalf under their own terms.

 

We do not otherwise disclose personal data to third parties, except where required by law.

 

## Children's data

 

Student names and classes are provided by the parent or guardian and are used only to prepare, label and deliver meals. Children do not have accounts and we do not collect data directly from children.

 

## How long we keep it

 

We keep personal data for **2 years** after the last order or message it relates to, and then delete it. Where Hong Kong law requires us to keep accounting records for longer, we keep only those records, only for as long as the law requires.

 

## Your rights

 

Under the Hong Kong Personal Data (Privacy) Ordinance you may ask us to:

 

- tell you what personal data we hold about you;

- correct anything that is inaccurate;

- delete personal data we no longer need to keep.

 

We will reply within 40 days, as the Ordinance requires.

 

## How to ask us to delete your data

 

Email **info@ghfoodservice.com** with the subject "Data deletion request", from the email address on your account (or tell us the phone number you contacted us from on WhatsApp), and say what you would like deleted. We will confirm your identity, delete the data, including your WhatsApp conversation history with us, and confirm by email when it is done. Records we must keep by law are kept only as long as required and then deleted.

 

## Security

 

Access to order, payment and customer service records is limited to authorised staff, who sign in with their own accounts. Our systems are access-controlled and changes are recorded.

 

## Changes to this policy

 

Any change will be posted on this page with a new "Last updated" date.
