Refund & Credit Policy

Effective September 1, 2026. Applies to the Tengsuan console, API and all compute services operated by Tengsuan ("we", "us").

Deposits and prepaid credits

Deposits are made in cryptocurrency and credited in USD at the rate at the time of payment. Unused purchased credits are refundable to a wallet you control on request to billing@tengsuan.cloud, at the USD rate on the day of the refund and less network fees, within one business day of approval. Deposits below the provider minimum, on the wrong network or in the wrong asset are held by the payment processor and are credited or recovered manually; they may not always be recoverable.

Invoices

Invoiced usage reflects metered runtime and is not refundable once the workload has run, including idle time during an active session. Disputed lines can be raised within 30 days of the invoice date.

Partial and over-payments

If a payment arrives short of the requested amount, we credit the value actually received. Over-payments are credited in full.

Promotional credits

Welcome, promotional and goodwill credits have no cash value and are not refundable or transferable.

Service issues

If a host or job fails to provision or is terminated because of a platform fault, the metered usage for that resource is credited back automatically or on request. Usage on hosts that ran normally, including idle time during an active lease, is not refundable.

Account closure

Request a refund of any remaining purchased credits before closing your account; balances under $10 are forfeited on closure. Open invoices remain payable.
