Shopify rejected my app over a field I never asked permission for, now it's live with 8 installs and I'm looking for brutal feedback
Solo founder, data engineer background. Spent about two months building Margeny, profit margin analytics for Shopify stores. Submitted to App Store review, got rejected.
The official reason was "error importing data, blocks the review." Took me a whole afternoon to find the real one. My queries were requesting customer email, which is Protected Customer Data on Shopify and needs explicit approval I hadn't asked for. The annoying part is dev stores are exempt from that restriction, so every single test I ran passed fine. It only broke the moment a real store touched it, which for a reviewer is the first time that happens.
Fixed it, resubmitted, got approved. It's live now.
Where I'm at: 8 installs, 0 reviews yet. Early enough that I'm still figuring out if the onboarding actually makes sense to someone who isn't me. It calculates real margin per order, COGS, payment fees, shipping, refunds, and cross references ad spend so you get profit after ads instead of just gross revenue.
If anyone here has a few minutes to poke at it and tell me what's confusing, missing, or just not worth paying for, I'd genuinely rather hear that now than after 50 installs. Not fishing for a nice review, actual criticism is more useful to me right now.
