Thanks jazzejeff1! I cant reply directly to your post - new account. Right now the license is a one-time purchase, not a subscription. The product is proprietary, so I don’t provide full source access, but I actively maintain and update it — if bugs appear, I’ll fix them. For customers who need long-term assurance, I’m open to providing source access under NDA or escrow if I ever stop maintaining the app, so you’re never left without a working version.
