Privacy Policy

Last updated: 9 November 2026

MTChat (chat.mt-labs.net) is run by Mind Theory & MTLabs in Singapore ("we", "us"). MTChat is meant for users in Singapore. This policy explains what personal data we collect, why, and your rights under Singapore's Personal Data Protection Act 2012 (PDPA).

1. What we collect

• Account details: name, email address, password (stored only as a secure hash), school, gender and year of birth.
• Your content: chats, prompts, files you upload, images you create, and code projects made with MTCode.
• Guest use: if you chat without an account, we record your IP address, a browser identifier, your browser type and language, your messages and the AI's replies. We use these to apply the daily chat limit and to look into abuse if it is reported.
• Enquiries: name, email and message when you use the Enterprise form.
• Technical data: IP address, browser type and server logs, used to keep the service running and secure.

2. Why we use it

• To create and manage your account, and approve access for your school or group.
• To give you answers, images, file edits and code, and to save your chat history for you.
• To apply daily usage limits and content filters.
• To send account emails such as approval and password reset.
• To reply to enquiries.
• To fix problems, prevent abuse and keep the service secure.

We do not use your chats to train AI models, show ads, or sell or rent your data.

3. Where your data is kept

Your account data and chats are stored, and every AI model runs, on our own servers in Singapore. Your chats are not sent to any outside AI provider.

A few services help us run MTChat:

• Cloudflare carries encrypted traffic between your browser and our servers.
• Our email hosting provider sends account emails and forwards enquiries.
• Web search: when a chat searches the web, only the search words are sent to public search engines to fetch results. Your account details are not sent.

4. Cookies and local storage

We use only cookies and browser storage needed to run the service: a sign-in cookie to keep you logged in, a "trusted device" cookie for admin two-factor login, and browser storage for your settings. We use no advertising or tracking cookies, and no third-party analytics.

5. Children and students

You must be at least 13 to create your own MTChat account. If you are 13 to 17, a parent or guardian must agree before you sign up. Children under 13 may use MTChat only through an account set up by their school, and the school is responsible for getting a parent's consent first. Parents can contact us at any time to see or delete their child's data.

6. Who can see your data

Only you, and a small number of our administrators when issues arise. If your account is part of a school group, that school's administrators may be able to manage your account. We share data with authorities only when the law requires it.

7. How long we keep it

We keep your account and chats until you delete them or your account is closed. You can delete individual chats at any time. Guest messages and usage records are deleted after 90 days. Server logs and enquiry emails are deleted after 6 months.

8. Security

All traffic is encrypted (HTTPS). Passwords are hashed. Admin accounts use two-factor login. No system is completely secure. If a data breach is likely to cause you significant harm, we will notify you and the PDPC as the PDPA requires.

9. Your rights

Your account details and chats are stored in MTChat itself, and you can see them there at any time. In MTChat you can:

• see and change your profile details in Settings;
• see all your saved chats, and delete any of them;
• ask us to close your account and delete what MTChat has stored for you.

For anything you cannot do yourself in MTChat, contact us below and we will reply within 30 days. If you ask us to delete your account, we can no longer provide the service to you.

10. Contact

Data Protection Officer: email [email protected] with the subject "MTChat Privacy Enquiry".

11. Changes

If we change this policy, we will update the date at the top. We will tell signed-in users about important changes.
