Hodohodo Shudo Terms of Service

Last updated: August 2, 2026

Article 1 (Application)


These Terms of Service (the “Terms”) govern the use of Hodohodo Shudo (the “App”). By using the App, you agree to these Terms.


Article 2 (Service Description)


The App provides the following features to support mindful drinking and moderation:


  • A personal moderation target for each party and logging for seven drink types, including water and non-alcoholic drinks
  • Points, collectible titles, and a pixel-art character based on your drink records
  • Settings for alternating alcohol with water or non-alcoholic drinks and recurring party reminders
  • Monthly calendars, charts, and statistics for reviewing your history
  • Custom messages and sharing of titles and party results
  • Japanese and English display options
  • An optional in-app purchase to support the developer

  • Article 3 (Important Information About Alcohol)


  • The App does not encourage alcohol consumption. It is intended to support mindful drinking and moderation.
  • The App is not a medical device or medical service. Consult a qualified healthcare professional if you have health concerns related to alcohol.
  • The App is intended only for people who are legally permitted to drink alcohol under the laws that apply where they live or use the App.
  • Driving under the influence is prohibited by law. Records and information in the App must not be used to determine whether it is safe or legal to drive, your level of intoxication, or your blood alcohol concentration.

  • Article 4 (Developer Support In-App Purchase)


  • The App offers “Buy the Developer a Drink” as an optional way to support the developer. It is a one-time consumable product, not a subscription.
  • A purchase does not unlock, add, or change any feature, content, right, or service in the App. You may choose to purchase the same product more than once.
  • The price is the amount shown in the App or App Store at the time of purchase and may vary according to your storefront and currency.
  • Payment is charged through the payment method registered to your Apple Account. Apple’s terms apply to purchase processing.
  • A confirmed purchase cannot be cancelled. Refund requests must be submitted to Apple under Apple’s refund policy through Report a Problem. We cannot issue refunds directly.
  • Family Sharing, purchase approval, payment methods, and other App Store features or restrictions are governed by Apple’s terms.

  • Article 5 (Data Handling)


  • Drink records, settings, achievements, and the in-app record of support purchases are generally stored on your device.
  • The App uses Firebase Analytics and Firebase Crashlytics to improve the service and its stability. Usage events, app and device information, crash information, and related data are sent to Google LLC.
  • If you use the in-app contact feature, your message, email address when you request a reply, anonymous user ID, and app and device information are sent to Google LLC through Firebase Authentication and Cloud Firestore.
  • The App uses Apple’s App Store and StoreKit to retrieve prices, verify transactions, and retrieve purchase history. Apple processes payment information; we do not receive credit card numbers or similar payment credentials.
  • The App uses Firebase Remote Config to retrieve settings such as support page URLs.
  • See the App’s Privacy Policy for details.

  • Article 6 (Notifications and Sharing)


  • Reminders require notification permission on your device. Notifications may not appear as scheduled due to operating-system conditions, device settings, or other circumstances.
  • When you use a sharing feature, an image and post text are passed to the destination you select. The destination service handles that information under its own terms and privacy policy.

  • Article 7 (Prohibited Conduct)


    You must not:


  • Violate applicable laws or public order;
  • Infringe the rights of the App or any third party;
  • Interfere with or misuse the App;
  • Decompile, reverse engineer, or modify the App except where permitted by law;
  • Redistribute or resell the App without permission; or
  • Engage in any other conduct that we reasonably consider inappropriate.

  • Article 8 (Disclaimers)


  • The App is provided “as is,” without warranties, express or implied, regarding completeness, accuracy, availability, continuity, or fitness for a particular purpose.
  • Points, titles, statistics, reminders, and other information in the App are for reference only and must not be used as the basis for medical or legal decisions.
  • To the extent permitted by law, we are not responsible for lost data or inability to use the App caused by device failure or loss, deletion of the App, operating-system changes, third-party services, or other circumstances.
  • We may change, suspend, or discontinue all or part of the App.

  • Article 9 (Intellectual Property)


    Copyrights, trademarks, and other intellectual property rights in the App, including its pixel art, animations, and design, belong to us or their respective lawful owners.


    Article 10 (Changes to These Terms)


  • We may update these Terms as necessary in accordance with applicable law.
  • Updated Terms take effect when posted in the App or on a website designated by us.

  • Article 11 (Governing Law and Jurisdiction)


  • These Terms are governed by and construed under the laws of Japan.
  • Unless otherwise required by applicable law, the Tokyo District Court has exclusive jurisdiction as the court of first instance over disputes relating to the App.
