Terms of Service

By registering for and using Sontis Management, you agree to these terms. If you do not agree, please do not use the service. These terms apply to all individual and organizational accounts.

• Each company registers one organizational account. • Accounts may not be transferred to third parties. • You are responsible for maintaining the security of your login credentials. • Notify us immediately if you discover unauthorized access.

You may use Sontis Management for lawful business purposes only. The following are prohibited: • Using the service for illegal activities. • Creating fake accounts or fictitious data. • Attempting unauthorized access to the system or other companies' data. • Reverse engineering, copying, or redistributing the software. • Using the service to directly compete with Sontis.

• Free plan: Permanently free with defined feature limits. • Paid plans: Prepaid per period (monthly/yearly). Prices shown on the pricing page exclude 10% consumption tax. • Paid plans AUTO-RENEW on the expiry date, charged to your registered card. You can stop auto-renewal at any time by downgrading to the Free plan before the renewal date. • Storage overage fees (¥20/GB/month, excl. tax) are automatically charged to your card on the 25th of each month. • We may change pricing with 30 days' advance notice. • All fees paid are non-refundable, except as otherwise specified.

Business data you enter into the system (customers, quotes, orders) is your property. Sontis has no right to use this data beyond providing the service. You may export your data at any time.

• You may cancel a paid plan (downgrade to Free) or stop using the service at any time. • After payment stops or cancellation, the account is suspended but YOUR DATA IS RETAINED FOR 12 MONTHS from the date of termination — you can reactivate and continue at any time during this period. • We will notify your registered email before deletion. After 12 months without reactivation, all data is permanently deleted and cannot be recovered. • You may request a full data export or early deletion at any time via support@sontis.app — processed within 30 days. • Statutory bookkeeping retention obligations (typically 7–10 years in Japan) remain your responsibility — please export and keep the records you need before deletion. • We may suspend accounts that violate these terms without prior notice.

We aim for 99.9% uptime but do not guarantee uninterrupted service. Scheduled maintenance is announced at least 24 hours in advance. We are not liable for damages caused by service interruptions beyond our control.

To the maximum extent permitted by law, Sontis is not liable for indirect, special, incidental, or consequential damages arising from the use or inability to use the service. Our total liability shall not exceed the service fees you paid in the most recent 3 months.

These terms are governed by the laws of Japan. Any disputes will be resolved in the Tokyo District Court.
