Privacy policy

Last updated: 15 October 2026

This policy explains how GREEN INFINITY LLP (UEN T06LL0372D), Singapore ("we"), handles data in Halycon, our advertising management service. It covers data we receive from Meta's platforms and from the online stores of the businesses we serve.

Data we use

How we use it

We use this data only to provide the service to the business it belongs to: to report results, match ads to orders, suggest tests and prepare changes for the business to approve. We do not use one business's data for another business, and we do not use it to build profiles of individual people.

Who we share it with

We never sell data. We share it only with service providers that help us run the service, such as hosting and secure backup providers, and the AI service providers that help us analyse results. They act on our instructions and may not use the data for their own purposes. When a business approves it, we send that business's own customer list to Meta or TikTok to build its ad audiences. The list is hashed before it is sent, as each platform requires, and is used only for that business's advertising. We disclose data if the law requires it.

Storage and security

Data is stored on servers we control, with encrypted off-site backups. Access is limited to people who need it to run the service and requires a login.

How long we keep it

We keep a business's data while it uses the service. When a business removes our access or asks us to delete its data, we delete it within 30 days, except where the law requires us to keep it longer.

Your choices

A business can remove our access at any time in its Meta Business or TikTok settings. To ask us to delete data, follow the data deletion instructions. To ask what data we hold, or to correct it, contact us.
