Hodohodo Shudo Privacy Policy

Last updated: 2026-10-14

Introduction


Hodohodo Shudo (the “App”) respects your privacy and handles information in accordance with this Privacy Policy.


Information We Handle


1. Information Stored on Your Device


The App primarily processes and stores the following information on your device:


  • Drink records: drink type, time logged, party session, moderation target, and session status
  • Settings: moderation target, alternating-drink settings, reminder settings, display language, custom messages, and onboarding completion status
  • Achievements: points, collected titles, and the dates those titles were collected
  • Legacy developer-support purchase history: previously stored transaction ID, date, and quantity. The current App leaves this data on the device without reading, updating, or retrieving it again.

    • Apple processes credit card numbers, bank account details, and other payment information used for a purchase. The App and we do not receive or store that payment information.


    2. Information Collected Through Firebase Analytics


    The production version of the App uses Firebase Analytics to understand usage and improve the App. Information sent may include:


  • App usage and device information automatically collected by the Firebase SDK, such as app launches and screen activity
  • The type of drink logged; total drinks, alcoholic drinks, and moderation target for a party; points; and total party count
  • Events such as changing a target or reminder, resetting data, deleting history, and changing messages
  • Title ID, title name, total points, and whether a title or party result was shared
  • Pro paywall views and their source; monthly or annual plan IDs; purchase starts, completions, cancellations, pending approval, failures; and restore outcomes

    • These events do not include your name, email address, the date or time of an individual drink record, or an App Store transaction ID. The Firebase SDK may automatically handle an app-instance identifier, device information, operating-system version, app version, and related information.


    3. Information Collected Through Firebase Crashlytics


    The production version of the App uses Firebase Crashlytics to detect and fix problems. When a crash or error occurs, stack traces, the state of the App at the time of the crash, app, operating-system, and device information, and identifiers generated or obtained by Crashlytics may be sent to Google LLC.


    4. Information Sent When You Contact Us


    If you use the in-app contact feature, the App signs in anonymously through Firebase Authentication and sends the following information to Cloud Firestore:


  • Your message
  • Your email address if you request a reply
  • Your Firebase anonymous user ID
  • App version, build number, platform, and operating-system version
  • Time sent

    • Using the contact feature is optional. You do not need to provide an email address unless you request a reply.


    5. Information Handled by Remote Config


    The App uses Firebase Remote Config to retrieve settings such as support page URLs. Standard connection information and app or device information handled by the Firebase SDK may be sent to Google LLC when the App retrieves configuration data.


    6. Information Handled for Pro Purchases


    The App uses Apple's App Store and RevenueCat to retrieve prices, process purchases, verify subscription access, restore purchases, and manage subscriptions. RevenueCat processes anonymous purchase-management IDs, product IDs, transaction information, purchase, renewal, cancellation, expiration and refund status, and app and device information. Purchase-management data is processed and stored on RevenueCat's and Apple's servers. Drink records, drink names, and custom messages are not sent to RevenueCat.


    How We Use Information


    We handle information to:


  • Provide drink logging, moderation targets, points, titles, history, reminders, sharing, and other App features;
  • Store and restore your selected settings;
  • Process Pro purchases, verify access and subscription status, and restore purchases;
  • Respond to inquiries and understand requests and defects;
  • Analyze usage, improve quality, and detect and fix crashes; and
  • Deliver App settings such as support page URLs.

    • Third-Party Services and Disclosure


    The App uses the following third-party services:


  • Google LLC: Firebase Analytics, Firebase Crashlytics, Firebase Authentication, Cloud Firestore, and Firebase Remote Config
  • Apple Inc. and its affiliates: App Store, in-app purchases, purchase history, and refund processing
  • RevenueCat: Pro access verification, restoration, and purchase management using anonymous purchase IDs and transaction and subscription information

    • We do not sell your information or provide it to advertising networks. Information is sent to the services above only as needed to provide the App, process payments, respond to inquiries, analyze usage, and improve quality. Information may be processed and stored on servers outside your country or region.


    For details about these services, see:


  • Google Privacy Policy
  • Firebase Privacy and Security
  • RevenueCat Privacy Policy
  • Apple Privacy Policy

    • Sharing Features


    When you share a title or party result, the App passes an image and post text to the iOS share sheet. You select the destination. The destination service handles shared information under its own terms and privacy policy.


    Retention and Deletion


  • Drink records, moderation targets, alternating-drink settings, messages, points, and titles remain on your device until you use “Full Reset” in the App or delete the App.
  • “Full Reset” does not delete support-purchase history, display language, notification settings, or onboarding completion status.
  • Deleting the App normally removes the App’s local data from your device. It does not remove purchase history managed by Apple or information retained by the operating system or third-party services. Legacy support history is not retrieved again. Pro can be restored with the Apple Account used for purchase. Deleting or resetting the App does not cancel a subscription.
  • To request deletion of information submitted through the contact feature, email us at the address below. We may ask for information, such as the email address used when sending the message, to identify the relevant record.
  • Analytics, crash, and purchase-management data are retained and deleted according to our settings and Google's, RevenueCat's, and Apple's policies.

    • Security


    We use reasonable safeguards designed to prevent unauthorized access, disclosure, or alteration of information. Information stored on your device is protected according to your device's security settings. No method of transmission or storage can be guaranteed to be completely secure.


    Privacy of Underage Users


    Because the App contains alcohol-related content, it is not intended for anyone who is under the legal drinking age under the laws that apply where they live or use the App. If we learn that we have intentionally collected information from such a person, we will respond in accordance with applicable law.


    Changes to This Privacy Policy


    We may update this Privacy Policy in response to legal requirements or changes to the App. If a change is important, we will provide notice in the App or on a website designated by us.
