Privacy Policy

Effective Date: September 9, 2026

This Privacy Policy describes how Shibashi ("we", "us", "our", or "Service") handles information in connection with your use of the Shibashi mobile application for iOS and the website located at shibashiapp.com. We are committed to protecting user privacy and operating under a strict data-minimization model.

1. Information We Process

Shibashi is engineered as a local-first mobile application designed to respect user privacy:

  • Local Study Progress Data: Your flashcard review history, SRS intervals, mastery stages, review queues, custom preferences, and study statistics are stored locally on your mobile device. We do not transmit or host your study deck progress on external tracking servers.
  • Purchase & Subscription Data: In-app purchases (such as Shibashi Pro subscriptions) are processed entirely by Apple via the iOS App Store. Subscription validation and receipt verification are handled securely through Apple App Store services and RevenueCat infrastructure. We do not collect, process, or store your credit card numbers, bank account details, or billing addresses.
  • Support Communications: If you voluntarily contact us via email at support@shibashiapp.com, we receive your email address, message content, and any attachments you provide solely for the purpose of answering your inquiry.
  • Anonymous Crash Diagnostics: Optional, aggregated, non-identifying crash and performance telemetry provided by Apple iOS may be collected to help us diagnose technical glitches and improve stability.

2. How We Use Information

We use the limited data described above exclusively for the following operational purposes:

  • To provide, maintain, and support the functionality of the Shibashi application.
  • To verify and unlock Shibashi Pro subscription access via the Apple App Store.
  • To respond to user customer support requests and technical inquiries.
  • To diagnose application crashes and publish software improvements.

3. Zero Third-Party Data Selling & Tracking

We state unambiguously that we do NOT sell, rent, trade, monetize, or share your personal data with third-party advertising networks, data brokers, or marketing firms. Shibashi contains zero third-party cross-app tracking scripts, behavioral analytics trackers, or target advertising SDKs.

4. Data Storage & Security

Because your flashcard progress is stored directly on your physical iOS device, you maintain full control over your data. You may back up or delete your data at any time via standard iOS backup or app management features. For network communications (such as App Store verification or email support), industry-standard Transport Layer Security (TLS/SSL) encryption is strictly enforced.

5. Children's Privacy (COPPA Compliance)

Shibashi does not knowingly collect or solicit personal information from children under the age of 13. The application contains no social networking feeds, public forums, or unvetted external links. If you believe a child has provided us with personal information, please contact us immediately at support@shibashiapp.com so we can delete it.

6. International Data Transfer & Compliance

Our operations comply with key international data privacy regulations, including the European Union General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). Users possess the right to access, rectify, or request deletion of any personal communications sent to our support team.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect app updates or regulatory adjustments. Any updates will be posted on this page with a revised "Effective Date". Continued use of the app constitutes acceptance of the updated policy.
