We do not intentionally collect sensitive personal data (such as NRIC numbers, financial account passwords or health information) through this website. Please do not upload such information unless we expressly ask for it through a secure channel.
3. How we collect personal data
- Directly from you when you submit a quote request, price-match / existing-quote form, site assessment or recce request, estimator enquiry, or email / WhatsApp message.
- Automatically when you browse our website (for example essential cookies, security logs and basic analytics necessary to operate the site).
- From service providers that host or process website content and files on our behalf (for example cloud hosting and secure file storage for uploaded quotations).
4. Purposes of collection, use and disclosure
We collect and use personal data for these purposes:
- Responding to enquiries and preparing quotations or price reviews.
- Arranging site assessments, recces and project discussions.
- Providing and improving our website, estimator and related tools.
- Communicating with you about your project, including via WhatsApp or email where you have contacted us through those channels.
- Complying with legal, regulatory and contractual obligations.
- Protecting our website and business against fraud, abuse and security threats (including rate-limiting of form submissions).
- Maintaining internal business records and administering our operations.
Where required under the PDPA, we will obtain your consent before collecting, using or disclosing your personal data, unless an exception applies (for example where the data is publicly available, or where use is necessary for a legal or business improvement purpose permitted by law).
5. Disclosure of personal data
We may disclose personal data to the following parties where reasonably necessary for the purposes above:

- Regulators, law enforcement or other parties where required or permitted by law.
We do not sell your personal data. Where we transfer personal data outside Singapore (for example to a cloud provider), we will take appropriate steps to ensure that the recipient provides a standard of protection comparable to the PDPA, as required by law.
6. Cookies and similar technologies
We use cookies and similar technologies to operate our website and remember your preferences.
- Essential cookies — required for security, session management (including administration access where applicable) and remembering your cookie consent choice.
- Functional / preference cookies — help the site remember choices that improve your experience.
- Third-party technologies — parts of the site may load content or services from providers such as font hosts, media delivery or messaging links. Those providers may process technical data under their own policies when you interact with their services.
When you first visit, you will see a cookie notice. You can accept cookies to continue with the full browsing experience, or manage preferences through your browser settings. Blocking some cookies may affect how certain features work.
7. Retention
We retain personal data only for as long as necessary to fulfil the purposes for which it was collected, or as required or permitted by Singapore law (for example accounting, dispute resolution or regulatory retention). When personal data is no longer needed, we will cease to retain it or anonymise it, so that individuals can no longer be identified.
8. Protection of personal data
We implement reasonable security arrangements to protect personal data against unauthorised access, collection, use, disclosure, copying, modification, disposal or similar risks. No method of transmission over the internet is completely secure; please take care when sharing information online.

- Withdraw consent to our collection, use or disclosure of your personal data (where consent is the basis for processing), subject to legal or contractual restrictions and reasonable notice.
To exercise these rights, contact us at build@cec.builders. We may need to verify your identity before responding. If withdrawing consent means we cannot provide a service you requested, we will explain the consequences.
If you have a complaint about how we handle personal data, please contact us first so we can try to resolve it. You may also contact the Personal Data Protection Commission (PDPC) of Singapore.
10. Third-party links and messaging apps
Our website may link to third-party sites or open third-party apps (including WhatsApp). Those services are governed by their own privacy policies. We are not responsible for their content or practices. Please review their policies before providing personal data through those channels.
