Refund Policy

Because the Service delivers generative AI output, paid fees and granted credits are non-refundable as a general rule.

1. Within 24 hours of payment and no credits used — full refund.
2. Partial refund for credit packs — within 24 hours of purchase with partial use, the unused remainder is refunded at the equivalent rate.
3. Service-side failure — when a generation job fails due to our system, the consumed credits are automatically returned to your account (no support contact required).
4. Other — when we determine the issue is clearly attributable to us, we may refund at our discretion.

• Unintended results due to user error (prompt mistakes, wrong settings).
• Results that disappoint due to model limitations (model behavior can be assessed beforehand).
• Voluntary mid-cycle cancellation (you retain plan features until the next billing date).
• Accounts suspended for Terms of Service violations.
• Credit packs purchased more than 24 hours ago (unused credits remain valid for 6 months).

1. Email info@stop.co.jp with:
   • Registered email address.
   • Payment date and amount.
   • Reason for refund.
2. We will reply within 1 business day after review.
3. If approved, we refund via Stripe to the original card. Settlement usually takes 5–10 business days.

Subscription credits roll over up to 50% of the monthly grant into the following month. Excess unused credits expire.

• Example: On the Nebula plan (2,000 cr/month), if your end-of-month balance is 1,500 cr, 1,000 cr roll over. Combined with the next month's 2,000 cr grant, your available balance becomes 3,000 cr.
• Credits from pay-as-you-go packs are valid for 6 months from purchase.
