HelloShark is a marketing tool created by DH Systems for the use of our clients.

All marketing data is gathered independently by our clients, and is held securely on our server. This data is not sold, passed on, or otherwise manipulated. This data is usually collated from past sale records, email subscriptions, website registrations, and similar data sources provided by our clients.

Unsubscribing from a newsletter from one of our clients delivered through the HelloShark system will remove you from all future newsletters from that client delivered through HelloShark. We do not control the original data, and cannot remove you from our clients' databases.
