Purpose and service line are Customer.io's own words, kept in the language they were published in — you could read them on their page, so we publish them here. Data types, transfer basis and usage are recorded, coded and filterable; those are ours, and they open with the watch. A relationship with nothing recorded shows no chips at all.
The day the list moves, this lands.
Not a digest of everything — the change, its classification, the path from Customer.io down to the entity that moved, and the source we read it from. The same alert covers a name added, a name removed, a jurisdiction shift and a change to the terms.
