Refund Policy ​

Last updated: October 2026

This Refund Policy explains how refunds are handled for the prepaid balance of ServerlessInsight. It forms part of the Terms of Service.

1. Prepaid Balance Model ​

The Service runs on a prepaid balance: you top up in advance, and monthly plan charges plus pay-as-you-go usage are deducted from that balance. Because charges are drawn only from funds you have already deposited, there is no subscription lock-in and nothing is ever charged to your payment method automatically.

2. What Is Refundable ​

Your refundable amount equals the part of your balance that is:

• unconsumed — not yet deducted as plan charges or usage; and
• un-invoiced — not covered by an invoice already issued (China line);

minus any refund requests currently in progress. The exact refundable amount is shown in the console before you submit a refund request. Already-consumed usage and invoiced top-ups are non-refundable.

2a. Plan Fees Are Non-Refundable; Cancellation ​

The Team plan fee is deducted from your balance per billing period and covers that period. Once deducted, a period's plan fee is non-refundable. Downgrading to Developer takes effect from the first day of the next billing period — your Team benefits remain intact until the end of the current period, and the unconsumed part of your balance remains refundable under this policy. Annual coverage needs no cancellation: there is no automatic renewal, benefits simply run until the coverage end date, and unused covered months are not refundable (see the clause below).

2c. Annual Plan ​

The annual fee covers 12 months of the plan base fee and the base-fee portion is non-refundable (this is the consideration for the "billed as 10 months" discount); overage usage still bills from your balance, and the unconsumed, un-invoiced part of that balance remains refundable under this policy. Billing errors are corrected unconditionally.

Cancelling an auto-renewed period: after a successful auto-renewal and before the current coverage ends, you may cancel the renewed period — the annual fee is returned in full to your prepaid balance and coverage rolls back to the previous end date. The unconsumed part of the balance can then be refunded through the ordinary flow. Once the renewed year has begun, whole-period cancellation no longer applies.

3. Arrears Come First ​

If your account is in arrears (a monthly bill exceeded the available balance), the arrears are settled — or deducted from the refund — before any refund is paid out.

4. How Refunds Are Processed ​

1. Submit a refund request from the console (Billing section); the console shows the refundable amount.
2. We review the request — typically within one to three (1–3) business days.
3. Approved refunds are returned to the original payment method: processed by Creem (Armitage Labs OÜ, Estonia) or Waffo (Waffo.com Limited, Hong Kong) as Merchant of Record for USD payments, or via Alipay for CNY on the China line. Bank processing times apply.

5. Refund Exceptions ​

Refunds may be declined where:

• the amount was already invoiced;
• the balance was consumed by usage or plan charges;
• a refund request for the same funds is already in progress;
• there are reasonable indications of fraud, abuse, or violation of the Terms of Service.

6. Billing Errors ​

If you are charged in error (for example, a duplicated billing run or an incorrect amount), we will correct the ledger and return the excess unconditionally — this is not subject to the exceptions above.

7. Payment Disputes and Chargebacks ​

Please contact us first at support@wentsen.com before opening a card dispute — we can resolve billing issues directly and faster than a chargeback process. Chargebacks initiated without contacting us may result in suspension of the account until resolved.

8. Changes to This Policy ​

Changes to this policy apply prospectively and never affect refund requests already submitted.
