The unlock is a single non-consumable purchase tied to your Apple ID, not a subscription. On a new or reset iPhone, open Settings in the app and tap Restore Purchases while signed in with the same Apple ID.
No account and no Panda Taps server. Your leases and readings stay on your iPhone and, if you use iCloud, in your own private iCloud. No analytics, no advertising, no tracking.
