You decide. We carry it out. The information your visitors leave with Caretta is yours to answer for. You choose whether to ask for it, which details to ask for, how long it is kept, and what you do with it afterwards. We only handle it to run the service for you, and only in the ways described here or in your written instructions.
Your settings in the dashboard are instructions. Switching contact collection on, choosing the fields, or changing the retention period all count as telling us what to do, and we act on them.
In the language of data protection law, you are the controller and WAPI Solutions LLC is the processor. That is the only pair of legal terms in this document, and it matters because every other clause follows from it.
