Privacy Policy

Last updated: 10 November 2026

This policy explains how Prex ("Prex", "we", "us") handles personal data. Prex is an AI assistant that real estate agencies use to answer people who contact them on WhatsApp. Prex is based in Nepal and can be reached at contact@prexhq.com.

1. Who is responsible for your data

When you message a real estate agency that uses Prex, that agency decides why your data is collected, and Prex processes it on the agency's behalf to run the conversation. For our own website and for messages you send directly to Prex, we are responsible for your data.

2. What we collect

WhatsApp details: your WhatsApp profile name and phone number.
Your messages: the text of messages you exchange with the agency's WhatsApp number, and the time they were sent.
Property preferences you share: for example budget, area, number of bedrooms, whether you want to buy or rent, and your timeline.
Appointment details: the date and time of any site visit you book.
Technical data: message identifiers and delivery status that WhatsApp provides, and basic server logs (such as IP addresses of requests to our servers) kept for security.

We do not ask for payment card details, government ID numbers or passwords in the chat, and you should not send them.

3. How we use it

To reply to your messages and answer your questions about properties.
To understand what you are looking for and show you matching listings from the agency.
To book, confirm or change site visits.
To pass your enquiry to the agency's staff so a person can follow up.
To keep the service secure, fix problems and prevent misuse.

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

4. Automated replies

Replies in the chat are written by an AI system. They can sometimes be wrong. Prices, availability and other details are confirmed by the agency, and you can ask to speak to a person at any time.

5. Who we share it with

The real estate agency you contacted, so its staff can help you.
Meta Platforms (WhatsApp Business Platform), which delivers the messages.
An AI model provider, which processes message text to help write replies. It may not use your data for its own purposes.
Cloud service providers that host our servers and the agency's lead records and calendar (for example Google Workspace).
Authorities, only when the law requires it.

These providers may store data outside your country. We use providers that protect data with appropriate safeguards.

6. How long we keep it

We keep conversation and lead data for as long as the agency uses Prex and needs it for your enquiry, and no longer than 24 months after your last message. Security logs are kept for up to 90 days. When an agency stops using Prex, we delete its lead data within 30 days.

7. Your rights and how to delete your data

You can ask to see, correct or delete your data at any time. To delete it, email contact@prexhq.com with the subject "Delete my data" and include the WhatsApp number you used. We will confirm and delete your data within 30 days, and tell the agency to do the same with any copy it holds.

You can also stop messages at any time by telling us in the chat that you want no more messages, or by blocking the number in WhatsApp.

8. Security

Data is encrypted in transit, access is limited to people who need it, and secret keys are kept out of our code. No system is perfectly secure, but we work to protect your data and will act quickly if something goes wrong.

9. Children

Prex is meant for adults looking for property. We do not knowingly collect data from anyone under 18. If you believe a child has used Prex, contact us and we will delete the data.

10. Our website

This website does not use cookies or analytics. Our website host may log IP addresses for security.

11. Changes to this policy

If we change this policy, we will update the date at the top of this page. Important changes will be announced on this page before they take effect.
