Terms of Service

App: MIO — Campus Life Organizer / Effective date: July 26, 2026 / Last updated: August 9, 2026

These Terms of Service (the “Terms”) set out the conditions for using the app “MIO” (the “App”) provided by misoclub (“we”, “us”). By using the App, you agree to these Terms. When you first launch the App, we ask you to agree to these Terms and the Privacy Policy. If you do not agree, you may not use the App.

1. Accounts

The App uses an anonymous identifier (a random ID) to enable sharing with friends and syncing across devices. No registration of your name or email is required. You may optionally link a Google or Apple account for backup and device migration. Data is handled in accordance with our Privacy Policy.

2. Fees and in-app purchases

The App is free to use and displays ads. It offers a paid plan, “MIO Premium” (in-app purchase), which removes ads, expands your storage allowance from 1,000 to 5,000 blocks, and adds circle, home-screen widget, and CSV export features. Purchases, payments, and refunds are handled by the App Store (Apple) or Google Play (Google) and are subject to their respective terms. For the transaction terms of purchases, please see the Act on Specified Commercial Transactions notice.

MIO Premium is an auto-renewing subscription, available as a monthly plan (1 month) or a yearly plan (1 year). When you confirm the purchase, your store account is charged. Unless you cancel at least 24 hours before the end of the current period, the subscription renews automatically for the same period and price, and you are charged on each renewal date. A free trial may be offered for your first subscription; unless you cancel at least 24 hours before the trial ends, it converts automatically to a paid subscription. Whether you are eligible for a trial is determined by the store and shown on the purchase screen.

You can cancel at any time in your store’s subscription settings (iOS: Settings > Apple Account > Subscriptions; Android: Google Play Store > Payments & subscriptions > Subscriptions). Cancellation is not possible within the App. If you cancel, you keep access until the end of the period you have already paid for. After that, your account returns to the free tier and ads are shown again. Data saved beyond the free storage allowance is never deleted, but you cannot save new data while you are over that allowance.

Your purchase is tied to your MIO account, so you can use it on any device signed in to the same MIO account, on either iOS or Android. A single purchase cannot be used by more than one MIO account at the same time; to move it to another account, use “Restore purchase” in the App and confirm the transfer.

Subscribing through both Apple and Google Play for the same MIO account does not provide duplicate or additional benefits. To avoid duplicate charges, check both stores and cancel any unneeded subscription in the store where it was purchased. If the App cannot temporarily verify your purchase status, it does not start a new purchase and keeps Premium features available while verification is pending.

The previously offered one-time purchase for removing banner ads is no longer available to new customers. Existing purchasers keep all MIO Premium benefits without an expiration date.

3. Prohibited conduct

When using the App, you must not:

4. User content

You are solely responsible for the content you enter, post, or share — such as circle board posts, event details and participants, bill-splitting information, and shared timetables or classes (“User Content”). We are not responsible for the content of User Content.

We maintain a zero-tolerance policy toward objectionable content and abusive behavior. The App provides a feature to report inappropriate content to us and to block specific users. We may review reports and, without prior notice, take necessary action, including removing content that violates these Terms and suspending or ejecting users who violate them.

If you issue and share a circle join request link, you are responsible for managing how widely it is distributed. Anyone with the link can only send a join request; membership takes effect only when a circle admin approves it. If a link spreads beyond what you intended, you can stop it and issue a new one from the App at any time.

5. Intellectual property

Intellectual property rights in the App and its materials (program, design, text, logo, etc.) belong to us or the rightful owners. You may not reproduce, modify, or redistribute them without our permission. Rights in User Content belong to each user; however, you grant us the right to use it to the extent necessary to provide the App’s features (sharing, display, backup, etc.).

6. Disclaimer (no warranty)

The App is provided “as is”. We make no warranty that the App is fit for your particular purpose, or as to its accuracy, completeness, usefulness, availability, freedom from errors or interruptions, or the truthfulness of information shared by other users. Displays such as classes, attendance, credits, purchases, and pay are estimates; please make final checks and decisions yourself.

7. Limitation of liability

Except in cases of our willful misconduct or gross negligence, we are not liable for any damage arising from your use of, or inability to use, the App. Disputes between users (regarding sharing, events, bill-splitting, etc.) shall be resolved between the parties, and we are not involved. Where applicable law does not permit a full disclaimer, our liability is limited to the extent permitted by law.

8. Changes, suspension, and termination of the service

We may change, suspend, or terminate the App without prior notice to users. We are not liable for any damage to users resulting from this.

9. Suspension and account deletion

If you violate these Terms, we may suspend your use of the App, or delete your account or content. You may also stop using the App and delete your data at any time via “Delete all data” in Settings.

10. Governing law and jurisdiction

These Terms and your use of the App are governed by the laws of Japan. In the event of a dispute regarding the App, the court having jurisdiction over our location shall be the exclusive agreed jurisdictional court.

11. Changes to these Terms

We may revise these Terms as necessary. If there are material changes, we will notify you by appropriate means, such as posting on this page or asking for renewed consent within the App. If you continue to use the App after a change, you are deemed to have agreed to the revised Terms.
