Terms of Service

Tsuikey lets users create reminders for themselves or paired users and review scheduled actions through notifications and screens.

The service is intended to reduce the burden of requests and reminders in close relationships such as families and couples.

Users create or access accounts through authentication methods provided by Tsuikey, such as Apple, Google, and LINE.

Notifications may be delayed or fail depending on device permissions, OS settings, network conditions, and external notification systems.

Do not rely only on Tsuikey notifications for important events that could affect life, body, or property.

Tsuikey offers the Family Plan as an auto-renewable subscription: 300 JPY/month or 2,200 JPY/year (tax included), with a 2-month free trial for first-time subscribers. After the trial, the subscription renews automatically at the selected plan's price.

Cancel anytime from your App Store / Google Play account settings; access continues until the end of the paid period. Refunds follow App Store / Google Play policies. Purchases can be restored on new devices.

Illegal acts, harassment, rights infringement, unauthorized access, and service interference are prohibited.

Tsuikey does not guarantee task completion, notification delivery, relationship improvement, or data completeness.

Except in cases of willful misconduct or gross negligence, the operator's liability is limited to the total fees you paid in the preceding 12 months.

These terms are governed by the laws of Japan. The Tokyo District Court has exclusive jurisdiction in the first instance. Tsuikey is operated by 株式会社SNOOTECH.

This is a summary translation. If there is any inconsistency, the Japanese version prevails.
