The directory is built so downgrading never destroys work you've done. If your Pro subscription lapses (Stripe drops the status), the listing flips back to the basic tier on qrrx.net, but every premium field you configured stays in the database, dormant.
You can still save the listing for free-tier edits. The save merges your free-tier changes with the existing premium config in storage — nothing in your Pro setup gets nuked. Your brand color, testimonials, gallery toggles, and treatment-guide opt-ins are still there. When you re-upgrade, every Pro field snaps back exactly as you left it.
This is intentional. Earlier versions of the editor stripped premium keys on save when the clinic was on the basic tier; that meant a Pro operator whose subscription expired would lose months of customization the next time they updated their phone number. We fixed that — saves on basic tier are non-destructive to Pro storage.
Aftercare and Pro are separate entitlements. Canceling one doesn't cancel the other. The QR Rx Aftercare badge hides when verified aftercare flips to inactive; Pro chrome stays as long as Pro is paid. Re-activating either is a single Stripe webhook away from restored.
