- Other features we may specify

Article 5 (Paid Plan)
- We offer a Paid Plan (DAYS Premium) in the App. Its contents and prices are shown on the purchase screen in the App.
- Purchases are made through in-app purchase on the App Store or Google Play. Payment is processed by Apple or Google, and payments and refunds are governed by the terms and procedures of the respective store.
- The Paid Plan is an auto-renewing subscription. Unless you cancel before the end of the current period using the method specified by the store, the period renews automatically and the renewal fee is charged.
- For plans that include a free trial, unless you cancel before the end of the trial, the subscription automatically converts to a paid period and the fee is charged.
- Cancel through the subscription management screen of the App Store or Google Play. Running "Delete all data" in the App or uninstalling the App does not cancel the subscription.
- After cancellation you can continue to use the Paid Plan until the end of the period already paid for. We do not provide pro-rated or other refunds for cancellation during a period, except where required by law or by the store's policies.
- We may revise the price of the Paid Plan. We will give advance notice through the method specified by the store and by notice in the App.
- When you change devices, you can restore your purchase from "Restore purchases" in the App by using the same store account you purchased with.
- Minors must obtain the consent of a parent or guardian before purchasing the Paid Plan.

- The App is not a medical device.
- The forecasts, condition displays, and tips provided by the App are general information intended to support your daily life and planning. They are not medical advice, diagnosis, or treatment.

- We may interrupt all or part of the App or the external services it uses without prior notice in the following cases:

- Any other case in which we judge provision of the App to be difficult
- We may terminate provision of the App with prior notice to you.
- We accept no liability for any damage you incur from changes to, interruption of, or termination of the App.

- The accuracy of calendar events and health data read by the App depends on the apps and operating system that manage them, and we do not warrant it.
- We accept no liability for any damage you incur arising from the App. This does not apply in cases of our willful misconduct or gross negligence, or where exclusion of liability is not permitted under consumer protection or other applicable law; in such cases our liability is limited to the amount of the Paid Plan fee you paid to us for the month in which the damage occurred.

Article 17 (Language)
- The Terms are provided in Japanese and English. In case of any discrepancy between the language versions, the Japanese version prevails.
