How data processing takes place in Datahash Signals?

Sub-domains are mapped to create an alternate route for first party data to be picked up from the client server. This data is SHA-256 encrypted (one-way hash) by the dhpixel code. Once this encrypted data is received by Datahash server, it is just passed onto FBM via conversion API.

No data retention at any stage.
