Why crypto only?

No email, no card, no personal details — the same reason sign-in is a wallet signature rather than an account. It does mean a wallet is required even for a small purchase, which is a real trade-off and not one we are pretending away.

What happens when a plan expires?

It reverts to Free. There is no recurring charge and nothing to cancel, because there is no stored payment method to charge again. Renewing early extends your existing expiry rather than replacing it.

What if I send the wrong amount?

Underpay and no plan is granted — we will not part-activate a subscription. Overpay and the difference is added to your credit balance rather than returned, because refunding to an address inferred from an inbound transfer is how funds get lost for good.

Do credits expire?

No. A credit balance is an append-only ledger entry, and it stays until it is spent.
