Who from Waise can enter my store?
Only staff who need access to help you, and every entry is logged and shown to you with a reason.
Waise's data processing terms say that only staff who need access to help you may access your store's data, and that they are bound by confidentiality. Every entry of a Waise staff member into your store is logged and shown to you.
You see it on the subscription screen (Settings, then Subscription) in the panel "Waise team access log": the date, who, and why. If nobody entered, it says "Nobody from the Waise team has signed in to your shop."
When you use "Talk to a person" in Pulse, the request carries a snapshot of your store's state. See How do I talk to a person on the Waise team?.
