Curve Pay available as alternative to Google Pay on GrapheneOS in certain regions

Some quick feedback with Curve Pay here: I have tried sending multiple documents when signing up to their service (usual KYC), all legit. They refused to open an account on the basis that they “could not verify my real identity”. Since they now have at least my ID card and passport, all legit, I tried to press on. Customer service turned out to be grossly incompetent with pre-written email replies unrelated to my queries. I’ve also been trying to reach the DPO, but no one’s answering over there. They seem to be very sketchy. Typical of a random fintech startup, I suppose. Wouldn’t surprise me if they do not store their customer’s data in a secure way and if leaks happen down the line.
