One purchasing business may use this exact version perpetually on its controlled devices, including by its officers, employees and contractors. Affiliates and clients do not receive product access. Later versions, updates, maintenance, custom work and live consulting are not included.

After verified payment, the private completion page automatically provides the ZIP. Save that private page URL for re-downloads. An automatic delivery email is not promised. If access fails or the link is lost, contact support@signalandship.com. Do not send PCB files, card details or secrets.

Japanese and English email support is handled manually, with an initial-response target of 48 hours.

After the purchased file first becomes available to download, refunds for a change of mind or mistaken purchase are generally unavailable. Refunds remain available for non-delivery, duplicate charges, material defects in the supported environment that cannot be resolved by reasonable correction or re-provision, and cases required by applicable law or the payment service.

Include the order reference, enough information to verify the purchaser, and a description of the issue. Please contact us promptly, preferably within 14 calendar days after provision starts. This is a contact target, not an unconditional refund guarantee or a deadline that ends legal or payment-service rights. If the product has not been provided, that target has not begun. Once a valid refund has been determined, BoardPort initiates or submits it within two business days, excluding Saturdays, Sundays and Japanese public holidays. Refunds use the original payment method and currency. A full refund includes collected tax; BoardPort charges no cancellation fee.

Earlier purchases keep the refund terms accepted at purchase, including the 14-day no-reason full-refund promise where it applied. Previous purchase terms

The offline executable was tested with known-match, known-difference and unsupported fixtures in the recorded environment. JSON and HTML reports were saved offline. The sale ZIP preserves the tested executable bytes; this is inherited runtime evidence, not coverage of every device or browser.

Stripe test-mode payment, delivery, re-download, full refund and same-link revocation were verified under the previous license. For this refund-policy revision, simulated payments rechecked delivery, re-download and download revocation after refunds for both old and new purchases. Production real-money end-to-end testing has not been run.

The initial 21-day sales window ends 2026-09-24 14:16:44 JST (UTC+09:00). The internal three-buyer continuation target never delays delivery or cancels an existing license.
