Test the flow.
No live purchase.

Sandbox only / 僅供測試

Use a PayPal Sandbox buyer account. Any price shown in Sandbox is test data, not an approved retail price. Sandbox transactions do not provide paid features or create a real payment obligation.

請使用 PayPal Sandbox 買家帳號。測試顯示的金額不是核定售價；測試交易不會開通正式付費功能，也不產生實際付款義務。

Plan terms / 方案

A prepaid plan is paid once for the displayed number of days; it does not renew automatically. A lifetime offer, if displayed, is paid once. Device allowances are shown before checkout. Automatic subscriptions are not enabled in this version.

固定期間方案一次付費，不自動續訂；若提供買斷方案，則一次付費。結帳前顯示可啟用裝置數，本版尚未啟用自動訂閱。

Existing policies / 既有條款

Existing refund terms are unchanged. Product-specific commercial terms, including the scope of any lifetime offer, must be finalized before live checkout opens. This test page does not add a seven-day refund promise.

維持既有退款條款，不新增七天退款承諾。正式商品條款與買斷授權範圍仍待定案，完成前不開放正式收款。
