Privacy Policy

Last updated: October 2, 2026

Cohalume Technologies Limited (“Cohalume,” “we,” “us,” or “our”) respects your privacy and is committed to handling personal data responsibly.

This Privacy Policy explains how we collect, use, retain and protect personal data when you visit cohalume.com, contact us by email, or otherwise interact with our corporate website.

This Privacy Policy applies to the Cohalume corporate website. Individual products operated by Cohalume may have their own privacy policies where appropriate.

Information We Collect

Information Collected Automatically

When you visit our website, certain technical information is transmitted as part of the normal operation of the Internet and web server infrastructure.

Depending on the request and our security configuration, this information may include:

  • IP address;
  • requested page or URL;
  • date and time of the request;
  • HTTP response status;
  • browser or device-related request information; and
  • information used to classify traffic for security purposes, such as whether a request appears to come from a person, automated system or other service.

We use this information primarily to operate, secure, maintain and troubleshoot the website.

Information You Choose to Provide

You may choose to contact us by email at contact@cohalume.com.

If you send us an email, we may receive information such as your name, email address, organisation, the contents of your message, and any other information you choose to provide.

Clicking an email link on our website does not itself submit your message or personal data to the Cohalume website. Your information is transmitted when you choose to send an email through your email service.

Search Information

If you use search functionality made available through the website, your search terms may be included in the requested URL and may consequently appear in website or security logs.

Please avoid entering sensitive personal information into search fields.

How We Use Personal Data

We may use personal data and technical information collected through the website to:

  • provide and operate the website;
  • maintain website functionality and performance;
  • protect the website, our systems and users from misuse, abuse or security threats;
  • detect, investigate and troubleshoot technical issues;
  • respond to company, product, business and partnership inquiries;
  • maintain appropriate business correspondence and records;
  • comply with applicable legal and regulatory requirements; and
  • establish, exercise or defend legal rights where necessary.

We do not use information collected through the corporate website for unrelated purposes without an appropriate basis.

Analytics, Advertising and Tracking

At the time of this Privacy Policy, the Cohalume corporate website does not use advertising pixels, behavioural advertising systems, session-recording tools or similar visitor-tracking technologies on its primary public pages.

We also do not currently use third-party analytics services on those pages.

If we introduce analytics, advertising or similar technologies in the future, we will update this Privacy Policy and our Cookie Policy as appropriate.

Cookies and Similar Technologies

The public Cohalume website is currently designed to operate without analytics, advertising or personalisation cookies for ordinary visitors.

WordPress and related website systems may use strictly necessary cookies in administrative or authenticated contexts, such as when an authorised administrator signs in to manage the website.

Additional information about our use of cookies and similar technologies is available in our Cookie Policy.

Service Providers

We may use third-party service providers to support the operation of our business and website, including providers of:

  • website hosting and infrastructure;
  • website security and technical services;
  • email and communications services;
  • backup and data-storage services; and
  • other services reasonably necessary to operate and protect the website.

These providers may process personal data on our behalf or as otherwise permitted by applicable law.

We seek to use service providers appropriate to the nature of the services they provide and the information they process.

International Processing and Transfers

Some of the service providers we use may operate infrastructure or process information in jurisdictions outside Hong Kong.

Where personal data is transferred or processed across jurisdictions, we take reasonable steps appropriate to the circumstances to protect the information and to use service providers that maintain appropriate safeguards.

Data Retention

We retain personal data only for as long as reasonably necessary for the purposes for which it was collected, including website operation, security, responding to communications, maintaining appropriate business records and meeting legal or regulatory requirements.

Retention periods may vary depending on the nature of the information, the purpose for which it is processed, security requirements and applicable legal obligations.

When personal data is no longer reasonably required, we take appropriate steps to delete, anonymise or otherwise dispose of it, subject to applicable legal and operational requirements.

Data Security

We take reasonable technical and organisational measures designed to protect personal data against unauthorised or accidental access, processing, alteration, disclosure, loss or destruction.

These measures may include access controls, website security tools, software maintenance, security monitoring, backups and other measures appropriate to the nature of the website and information involved.

No method of Internet transmission or electronic storage can be guaranteed to be completely secure, and we cannot guarantee absolute security.

Your Privacy Rights

Depending on your location and applicable law, you may have rights in relation to your personal data.

Under Hong Kong’s Personal Data (Privacy) Ordinance, individuals may have rights to request access to personal data held about them and to request correction of inaccurate personal data.

Other applicable laws may provide additional rights in appropriate circumstances.

If you wish to make a privacy-related request, please contact us at:

We may need to verify your identity before responding to certain requests where permitted or required by law.

Children’s Privacy

The Cohalume corporate website is not designed for the purpose of collecting personal data from children.

If you believe that a child has provided personal data to us through the corporate website, you may contact us at contact@cohalume.com so that we can review the matter and take appropriate action.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our website, business practices, service providers, legal requirements or privacy practices.
