Privacy Policy
Effective date: 2026-05-25 · Last updated: 2026-10-20
Yuuki Hyodo provides the apps 1人玉入れ 世界選手権 (Tamaire Alone), BubbleHeading, コレスタ (Collecting Stardust), and related app or website features (collectively, the "Services"). This Privacy Policy explains how information is collected, used, shared, and protected when you use the Services.
By using the Services, you agree to the collection and use of information in accordance with this Privacy Policy and the Terms and Conditions. I do not sell your personal information.
I do not directly collect personal information unless you choose to provide it, such as when you contact me by email or use an app feature that requires information. Depending on the app, platform, and feature you use, the following information may be processed by me or by third-party service providers:
This information is used to provide and improve the Services, operate rankings and purchases, respond to inquiries, prevent fraud or abuse, analyze performance, fix defects, deliver ads where applicable, and comply with legal or platform requirements.
Google account linking in Collecting Stardust is optional. You can play the standard game modes without it. If you choose to link Google in Settings, Google Sign-In requests the basic identity permissions openid, email and profile. These permissions cover your Google account identifier and basic profile information, such as your name and email address. The linking flow does not request access to Gmail messages, Drive files or contacts.
Google handles sign-in, and the game sends the resulting one-time authorization code to Microsoft Azure PlayFab to associate that Google account with the game account you are currently using. The game checks the link status returned by PlayFab. The account association is managed with your game account by PlayFab; it is not a public ranking entry. This linking feature currently does not restore progress on a new device.
The retention and deletion section below also applies to game-account information. You may request deletion through hyodo.app.contact@gmail.com.
コレスタのGoogleアカウント連携は任意で、通常のゲームモードは連携せずに遊べます。 設定から連携を選ぶと、Googleのアカウント識別子、名前、メールアドレスなどに関わる基本的な本人識別の権限 （openid・email・profile）を使用します。Gmailのメール、Google Driveのファイル、連絡先へのアクセスは求めません。 Googleによる認証後、ゲームは一度限りの認証コードをMicrosoft Azure PlayFabへ送り、現在使っているゲームアカウントと Googleアカウントを関連付け、連携状態を確認します。この関連付けはPlayFabでゲームアカウントとともに管理され、 ランキングへの公開情報としては使用しません。現在、この連携による新しい端末への進行状況の復元には対応していません。 保持・削除については以下のData Retention and Deletionをご確認ください。
iOS purchases are processed by Apple. To operate purchases, confirm purchase entitlements, prevent fraud, and analyze purchase performance, Unity In-App Purchasing may send product and transaction information (including price, currency, purchase status, transaction identifiers and store receipts or signed transaction data), together with device, installation and session identifiers and technical device information, to Unity. This purchase processing is separate from the game's disabled custom gameplay analytics. The game does not collect your payment card or bank account details.
For information about Unity's processing, please see the Unity Game Player and App User Privacy Policy. You may send questions and deletion requests concerning the game to hyodo.app.contact@gmail.com. Transaction information may be retained where required for legal obligations, financial records or fraud prevention.
iOSの購入代金の決済はAppleが行います。購入機能の提供、購入権利の確認、不正防止、購入状況の分析のため、 Unity In-App Purchasingは商品・取引情報（価格、通貨、購入状態、取引識別子、ストアのレシートまたは署名付き取引データ）を、 端末・インストール・セッションの識別子や技術的な端末情報とともにUnityへ送信する場合があります。 この購入処理は、ゲームで無効にしている独自のプレイ分析とは別のものです。 ゲームはクレジットカードや銀行口座の情報を取得しません。問い合わせ・削除依頼は上記メールアドレスへご連絡ください。 取引情報は、法的義務、会計記録、不正防止のために保持される場合があります。
The Services may use third-party services that collect information used to identify you or your device. Please review the privacy policies of the third-party service providers that may be used by the Services:
If an error occurs or the Services are used, third-party products may collect log data. Log data may include your IP address, device name, operating system version, app configuration, time and date of use, crash details, and other statistics.
The apps do not explicitly use browser cookies. However, third-party code and libraries may use cookies or similar technologies to collect information and improve their services. This website may also use cookies or similar technologies for basic functionality and analytics.
Information is retained only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law, platform rules, fraud prevention, or dispute resolution. You may request deletion of information associated with the Services by contacting me at the email address below. Some information may remain where deletion is technically impossible, legally restricted, or limited to aggregated or anonymized data.
I value your trust and use commercially reasonable means to protect information. However, no method of transmission over the internet or method of electronic storage is 100% secure, and I cannot guarantee absolute security.
The Services may contain links to external sites or services that are not operated by me. I have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services.
The Services are not directed to children under the age of 13. I do not knowingly collect personally identifiable information from children under 13. If I discover that a child under 13 has provided personal information, I will take reasonable steps to delete it. If you are a parent or guardian and believe your child has provided personal information, please contact me.
I may update this Privacy Policy from time to time. Changes will be posted on this page, and the effective date will be updated when appropriate. You are advised to review this page periodically.
