What to write to us about

• A figure looks wrong

  Tell us the address or project, the number you see, and what you believe it should be. Transaction data comes from URA and HDB, so a correction may need the official record behind it, and we will say so.

• Your account or haio+

  Sign-in problems, your haio+ plan, billing or cancelling: write from the email address on your account so we can find it.

• Partnerships and services

  Agencies, developers, banks and home-service providers who want to work with haio.

• Press and research

  Questions about haio Research, our market analysis, or how a number was produced. The methodology page answers most of them.

• Developers

  Questions about the free public API, or a use case it does not cover yet.

• Your personal data

  Access, correction or deletion requests under Singapore's PDPA. The privacy policy explains what we hold and why.
