Refund Policy

Last updated: July 29, 2026

  1. The Free Trial plan is available for users to try at no cost. Once a paid plan has been used (i.e., at least one AI itinerary generation has been recorded), fees for that billing period are 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. Once an annual Pro plan has been activated, it may not be switched to another plan mid-term, nor may a partial refund be requested. A full refund may only be requested under items 1–3 of this policy, either while the plan is unused or under the force majeure circumstances described in item 2.
