Great question. Here is an honest breakdown of the current state and what to expect:

Right now — No costs at all.

The app as it currently exists is purely a frontend UI. There is no payment system connected, no backend, and no database. The "Purchase & Download" buttons are display-only and do not process real transactions. You are not being charged anything.

If you add Stripe payments (which was discussed earlier), costs would be:

Stripe fees (per transaction):

• 2.9% + $0.30 per successful card charge (standard rate for most countries)
• For example, a $5.00 pattern sale → Stripe keeps ~$0.45 → you receive ~$4.55
• No monthly fee — you only pay when you make a sale

Hosting on Vercel:

• The free Hobby plan is sufficient for a small pattern shop
• No cost unless you need custom domains, team members, or high traffic

No other hidden costs — no database fees for this app size, no AI API costs, nothing else.

Summary: The app currently costs $0 to run. If you add Stripe, you only pay a small percentage per sale made — there are no upfront or monthly fees. You would like me to proceed with connecting Stripe so customers can actually pay before downloading?

Let me pick up where we left off and complete the full Stripe payment flow!
