Privacy Notice

Last updated: August 2026

This notice explains what Makan Split and Rumah Split collect about you, why, who sees it, and what you can ask us to do with it. It is issued under the Personal Data Protection Act 2010.

Makan Split splits a restaurant bill among the people at the table. Rumah Split settles rent and utilities among the people in a house. They share one account and one set of practices, and where something applies to only one of them, this notice says so.

1. What we collect

Only what the product needs to work.

  • Your mobile number. It is how you sign in and how we know which chair in a house is yours. We never see a password because there is not one.
  • Your name, as you or your housemate typed it. It is shown to the other people in your split or your house so they know who is who.
  • Receipt photographs, in Makan Split. They are read to pull out the items and prices, and are not kept afterwards.
  • Your DuitNow ID, if you give us one, so people can pay you.
  • In Rumah Split: the name of your house, the room you are in if the leader recorded one, the bills the house pays, and the amount you owe on each.
  • In Rumah Split, if you choose to send one: an export of your house group chat. It is read once to find the bills. Sender names are replaced with labels before it leaves us, but names written inside messages are not, and roughly three quarters of the messages in a house group are sent for reading.
  • Basic usage records: when you signed in, what you did in the app, and the device and network you did it from.

2. When somebody else gives us your number

In Rumah Split, whoever runs a house adds housemates by typing their mobile number, so we may hold your number before you have heard of us. Three things follow, and they are commitments rather than descriptions.

  • A number on its own does nothing. It sits on an empty chair until the person who can receive a code on it signs in and agrees to this notice themselves. Nobody consents on your behalf.
  • Until you sign in we send you nothing, and the person who added you cannot see anything about you that they did not type in.
  • If you never sign in, tell us and we will delete the number. You do not need an account to ask.

3. Who can see what

This is enforced by the database, not by the screens. A request for something you are not allowed to see returns nothing at all.

  • In a house you see every bill the house pays and your own amount on each one. You do not see what anybody else pays, and nobody sees yours.
  • Whoever runs the house sees every amount in it, because they are the one who sets them.
  • People outside your house see nothing about it, including its name.
  • Our own staff see counts and timings across houses, with no names attached. Reading anyone in particular takes a deliberate lookup, and we do that for support and for fraud, not out of interest.

4. Who we share it with

We do not sell your personal data, and we do not share it so anyone else can advertise to you. We use these providers to run the service, and they process your data on our instructions:

  • Supabase, for the database and sign-in. Data is held on servers in Singapore.
  • Twilio and WhatsApp, to deliver your one-time code and reminders.
  • Google, for reading receipt photographs in Makan Split, and for reading house group chat exports in Rumah Split. A chat you send is processed by Google Gemini, not by us.
  • Vercel, for serving the website.

We also disclose data where the law requires it, or to investigate fraud or abuse of the service.

5. Sending data outside Malaysia

Our servers are in Singapore and some of our providers operate elsewhere, so your data leaves Malaysia. We use providers who are contractually bound to protect it to the standard this notice describes.

6. How long we keep it

Receipt photographs go as soon as the items have been read. A house group chat you send is never stored at all; what the reader found from it, which includes the housemates it saw and when each bill was mentioned, is deleted within 24 hours. Everything else stays while your account exists, and afterwards for as long as we need it to settle money that was still owed or to meet a legal obligation. When you delete your account we remove your personal data; a record of what a house owed can remain in that house without your name on it, because it is the other housemates’ record too.

7. Your rights

Under the PDPA you may ask us to:

  • show you the personal data we hold about you
  • correct it if it is wrong
  • stop processing it, or stop sending you messages
  • delete your account, which you can also do yourself in the app

Write to the address below and we will answer. We may ask you to prove the number is yours before we act, because that is the only way we can tell it is you.

8. Keeping it safe

Data is encrypted in transit and at rest. Who may read which row is decided in the database itself rather than by the app, so a mistake in a screen cannot expose somebody else’s amounts. Staff access is limited to the people who need it. No system is perfect, and if a breach happens that puts you at risk we will tell you.

9. Children

This service is not for people under 18. If you believe a child has given us personal data, tell us and we will remove it.

10. Changes, and how to reach us

If we change this notice in a way that matters, we will say so in the app before it takes effect. For anything here, including a request about your data, write to makan-split@shardlab.com.
