Sale Armor uses Apple's Screen Time to shut apps, and iOS can withdraw that permission after a restore, a device transfer, or a major update. Reopen the app and tap Protect my wallet. If the prompt doesn't appear, check Settings → Screen Time → App & Website Activity is on.
Open Sale Armor. It checks the clock on every launch and drops a shield that has outlived its window. If they're still shut, tap Disarm — that clears the shield immediately, with no confirmation step.
Tap Restore on the paywall. Make sure you're signed into the same Apple Account you paid with — Settings → tap your name → Media & Purchases.
Settings → tap your name → Subscriptions → Sale Armor → Cancel. Deleting the app does not cancel it. The app keeps working until the period you've paid for runs out.
Yes. Nothing is stored anywhere but the device, which is the trade for having no account. Your subscription survives, though — reinstall and tap Restore.
Please say which iPhone and which iOS version. There are no logs to send — the app doesn't collect any.
