3. The App provides an encrypted backup feature (using an industry-standard symmetric-key cipher) and an encrypted ZIP export feature for academic society-standard forms and other formats. Files exported in this way leave the device, and the User is responsible for managing where they are sent (e.g., cloud storage, email) and how they are shared.
4. If On-Device Data contains personal information as defined under Japan's Act on the Protection of Personal Information (such as name, date of birth, address, patient number, or any other information that can directly or indirectly identify a specific individual), the User shall handle such information appropriately at their own responsibility, in accordance with their employer's rules and applicable laws (the Act on the Protection of Personal Information, the Medical Care Act, the Medical Practitioners' Act, etc.).

1. Results of calculation tools (eGFR, Cockcroft–Gault, infusion rate, BSA, BMI, etc.) are reference values and may contain errors arising from the choice of formula, coefficients, rounding, or user-entered input. The User must verify results by other means (validated medical devices, package inserts, guidelines, etc.) before applying them to medical care.
2. The App's automatic generation of specialist-application forms (e.g., Excel/Word templates for various medical societies) is based on official forms confirmed by the Developer at the time of authoring. Medical societies may change, update, or discontinue forms without notice. The User must verify the latest forms and instructions and check and correct generated content before submission. The Developer assumes no liability for any inconvenience arising from form mismatches, content errors, or post-submission rejection.
3. Notification features such as the in-App notice feed, reminders, and monthly recap dialogs do not guarantee reliable delivery or display. Users are advised not to rely solely on the App for mission-critical medical reminders.

§17 Governing Law & Jurisdiction

1. These Terms are governed by the laws of Japan.
2. The Kurume Branch of the Fukuoka District Court shall have exclusive jurisdiction as the court of first instance over any dispute arising out of or relating to these Terms.

ZeroMiss Lab (the "Developer") complies with the Act on the Protection of Personal Information of Japan and other applicable laws regarding the handling of user information collected through the App.

§1 Information Collected

Information handled by the App falls into the following categories. On-device data (including any patient information) is not accessible to the Developer.

Patient information, notes, tasks, procedure records, calculation results, specialist-training progress, profile data (name, specialty, graduation year, photo, etc.) and all other data entered by the User are stored only within a secure area on the User's device and are not automatically transmitted to the Developer's servers or to any external party.

In addition, for the purpose of quality improvement, defect identification, and understanding usage trends, the App collects anonymous statistical information and usage information (feature-usage frequency, screen transitions, error logs, etc.) that cannot identify any individual, through an external cloud database and an app-analytics platform. Such information does not include any patient information, name, photo, user-entered text or other personal information.

The App also connects to an external cloud database operated by the Developer in order to retrieve in-App notices. These requests do not include any personal information of the User.

Installation, updates, and purchases of the App (if paid features are introduced in the future) are processed through the App Store operated by Apple Inc. Apple's handling of information is governed by Apple's privacy policy.

§2 Purpose of Use

Collected information is used solely for the following purposes:

1. Providing the App's functionality (patient information management, task reminders, calculation tools, specialist-progress tracking, exports, etc.).
2. Improving the quality of the App, fixing defects, and developing new features.
3. Statistical understanding of the App's user population (e.g., distribution by specialty or years since graduation).
4. Delivering important notices regarding the App.
5. Responding to violations of these Terms or this Policy.
6. Other operational activities required to run the App.

§3 Device Permissions

With the User's explicit permission, the App accesses the device's camera and photo library (to take or select profile photos), microphone (for voice input in notes and similar features), notifications (for task reminders, alerts for missing discharge summaries, and notifications of new notices), and biometric authentication (Face ID / Touch ID, for App lock and identity verification on exports). Information obtained or used through these features is retained on the device, and voice data or other input is not transmitted to the Developer's servers. For biometric authentication, the biometric data itself remains within the device and the App receives only the authentication result. The App does not collect location information. Each permission can be granted or revoked at any time in the device settings.

§4 Third-Party Disclosure

The Developer will not provide personal information to third parties without obtaining the User's consent in advance, except in the following cases:

1. When required by law.
2. When necessary to protect the life, body, or property of any person and obtaining the consent of the data subject is difficult.
3. When specifically necessary for improving public health or promoting the sound upbringing of children and obtaining the consent of the data subject is difficult.
4. When cooperating with a national or local government, or a person commissioned thereby, in performing duties prescribed by law, and obtaining the consent of the data subject may impede the performance of such duties.
5. When personal information is transferred as part of a business succession resulting from a merger, corporate split, or similar transaction.

§5 External Services & International Transfer

To operate the App, the Developer uses an external cloud database (for storing anonymous analytics data and for retrieving in-App notices), an external app-analytics platform (for usage analysis and crash reporting), and the App Store operated by Apple Inc. (for distribution and purchase processing). Cloud-infrastructure providers used by the App may be located outside Japan, and the User's anonymous analytics data and usage data may be transmitted to and stored at the data centers of those providers. Information required under Article 28 of Japan's Act on the Protection of Personal Information regarding cross-border transfer of personal data (including provider names, an overview of the personal-information-protection framework in the receiving country, and the measures taken by such providers) will be disclosed upon request to the contact in §13. Apple's handling of information is governed by Apple's privacy policy (https://www.apple.com/legal/privacy/).

§6 Tracking (ATT)

1. The App does not perform cross-site/cross-app tracking that would fall within Apple's App Tracking Transparency (ATT) framework.
2. The App is configured not to use the advertising identifier (IDFA); aggregation is based on a resettable, vendor-scoped identifier (effective only across apps from the same developer) only.
3. The App does not display advertisements.

§7 Security Measures

1. On-Device Data remains, in principle, on the device. The only export path is the encrypted backup feature, which uses an industry-standard symmetric-key cipher and always requires a user-set password.
2. All communication with external services is encrypted over HTTPS. Only anonymized information is transmitted as anonymous analytics data.
3. The App provides biometric authentication (Face ID / Touch ID) for App lock. Because the App handles data that may include patient information, enabling this feature is strongly recommended.
4. The Developer takes technical and organizational measures reasonably necessary to prevent the leakage, loss, or damage of user information.

§8 User Rights and Disclosure Requests

1. The User may request, under Japan's Act on the Protection of Personal Information, that the Developer (a) notify the User of the purpose of use; (b) disclose, correct, add to, or delete the User's personal data; or (c) stop the use, deletion, or third-party provision of such data.
2. After verifying identity, the Developer will respond without undue delay in accordance with applicable law. Note that, given the App's offline-first design, the personal data held by the Developer is very limited.
3. To delete On-Device Data, the User may use the App's "Delete All Data" function or uninstall the App.
4. To stop collection of usage data, the User may uninstall the App. Individual opt-out is not currently provided.
5. Contact information for requests is listed in §13.

§9 Children's Privacy

The App is intended for medical professionals and is not directed at children under the age of 13 ("Child" under the U.S. Children's Online Privacy Protection Act). The Developer does not knowingly collect personal information from children under 13. If the Developer learns that the App has collected personal information from a child under 13, the Developer will promptly delete such information.

§10 Retention & Deletion

1. On-Device Data is retained until the User uninstalls the App or uses the "Delete All Data" function within the App.
2. Anonymous analytics data is, in principle, retained by the Developer for the duration of App provision.
3. Usage data is retained according to the default retention period set by the relevant service provider (typically around 14 months).

§11 GDPR / CCPA

1. Users residing in the European Economic Area, the United Kingdom, or Switzerland ("EEA Users") may be entitled to the rights of the General Data Protection Regulation (GDPR), including the rights of access, rectification, erasure, restriction of processing, data portability, and objection.
2. Users residing in California, USA may be entitled to rights under the California Consumer Privacy Act (CCPA), including the right to know, the right to delete, and the right to opt out of sale. The Developer does not sell users' personal information.
3. Users wishing to exercise such rights may contact the Developer using the information in §13.

§12 Amendments

1. The Developer may amend this Policy from time to time. Where applicable law requires user consent, the amended Policy shall apply only to Users who have consented through the prescribed method.
2. The Developer will notify Users of the timing and content of amendments through this page, the in-App notice feature, or other appropriate means.

§13 Contact & Complaints
