Three tiers. Each includes the record. The difference is how much of the household it covers, and for how long after.
All tiers renew automatically. Coverage continues whether or not you do. Downgrades take effect at the end of the ledger, which does not end.
Can we export the household record?
The record is viewable at any time, at the record.
What happens if we cancel?
Billing stops. The record continues, read only, out of courtesy.
Is there a free tier?
There was. The households on it are still there.
