Refund Policy

Last updated: September 20, 2026

  1. The Free Trial plan is available for users to try at no cost. Paid plans renew automatically; once a billing period has been charged and the plan has been used in that period (i.e., at least one AI itinerary generation has been recorded), the fee for that period is non-refundable in principle.
  2. "Use" as referred to above does not include cases where, due to force majeure or circumstances attributable to the Company (e.g., system failure, service interruption), the user was unable to actually obtain an AI-generated itinerary result. Once verified via the Company's backend records, such cases are not counted as usage, and the user may apply for a refund under this policy.
  3. Refund requests must be submitted via our support email (yentechstudio@gmail.com). We will respond with a decision within 7 days of receiving the request; for requests confirmed as eligible, the refund process will be initiated within 7 days.
  4. The actual time for a refund to reach your account depends on the processing procedures of our third-party payment provider (NewebPay). We cannot guarantee an exact arrival time, but will make reasonable efforts to help you track progress once the refund has been initiated.
  5. You may cancel your subscription at any time from the Subscription page of this Service. Cancelling stops all future charges, but the period that has already been charged is not automatically refunded — its benefits remain available until that period ends. To request a refund for the current period, the conditions in items 1–3 of this policy still apply: the period must be unused, or the force majeure circumstances described in item 2 must apply.
