• You are responsible for activity in your account unless it is caused by our systems.
• You must provide accurate account information (for example, a valid email address).

5. Subscriptions, Billing, and Refunds

Subscription prices, billing periods, and payment methods are described on the pricing page. If a refund policy is offered (for example a “money-back guarantee”), it will be described on the pricing page or at checkout and may include eligibility conditions.

6. 許容される利用

You agree to follow our 利用許諾ポリシー. If your use violates that policy, we may suspend or terminate your access.
