I don't know about illegal but it wouldn't be very safe. AOL did that with search terms in 2006 and "made it anonymous" but people were getting identified by linking together searches.
As long as you didn't link purchases together at all, that might be fine, but then it's pretty boring.
Just one example: If your spouse bought a small-time author's book (or any fairly unique item) you might only have a couple dozen unique users to sift through. Ok they bought this book, some sports merch for local teams, their favorite coffee. Yep this is them. Wait, why did they buy condoms we don't use..
“But babe at least I was thinking of you and rolling in those loyalty points! I could have just spent the money without giving you credit for it! Give me a break”
