Tatsuo Nakano Privacy Policy

Your privacy is important to us. It is Tatsuo Nakano's policy to respect your privacy and comply with any applicable law and regulation regarding any personal information we may collect about you, including via our app (“This App”) and its associated services.

Personal information is any information about you which can be used to identify you. This includes information about you as a person (such as name, address, and date of birth), your devices, payment details, and information about how you use an app or online service.

If our app contains links to third-party sites and services, please be aware those sites and services have their own privacy policies. After following a link to any third-party content, you should read their posted privacy policy. This Privacy Policy does not apply to your activities after you leave our app.

Information We Collect

Information we collect falls into one of two categories: voluntarily provided and automatically collected.

Voluntarily Provided

Any information you knowingly and actively provide us when using our app and services.

Automatically Collected

Information automatically sent by your device in the course of accessing our app and services.

Log Data

When you access our servers via our app, we may automatically log standard data provided by your device. This may include your IP address, device type and OS version, app version, language, time zone, your activity within the app, and time/date stamps. When errors occur, we may collect crash and performance data (e.g., stack traces, device state, network status).

  • Email address
  • In-app purchase status (from Google Play / Apple App Store, no card numbers)
  • Advertising IDs (Google AAID, Apple IDFA) – used for serving personalized and non-personalized ads through Google AdMob
  • Analytics identifiers (Firebase Installation ID)
  • RevenueCat identifiers (App User ID, Entitlement Status) – used for managing subscriptions and purchases
  • Usage metrics (sessions, screens viewed, features used)
  • Approximate location (region-level, from IP)

Third-Party SDKs and Services

  • Google AdMob / AdSense – ads and monetization (uses Advertising IDs for personalized and non-personalized ads)

  • Google Firebase Crashlytics – crash reporting
  • RevenueCat – subscription management, purchase validation, entitlement tracking

Children’s Privacy

Our app is not directed to children under 13, and this app does not target individuals under the age of 13. We do not knowingly collect personal information from children under 13. If such information is discovered, we will delete it promptly.

Security & Data Retention

We use commercially reasonable measures to protect your data. Retention lasts only as long as necessary for service provision and legal obligations. Afterwards, data is deleted or anonymized.

Your Rights & Controls

  • Opt-out of personalized ads (via device settings on iOS/Android)
  • Control analytics tracking (via device or in-app settings)
  • Request access, correction, or deletion of your personal information

Disclosure of Personal Information

We may disclose personal information to service providers, employees, regulators, or in connection with business transfers. We do not sell personal information for money. Some U.S. state laws consider ad/analytics sharing a “sale” or “sharing,” and you may have the right to opt out.

Analytics (GA4) & Google Search Console

Google Analytics (GA4)

We use Google Analytics (GA4) to understand how visitors use our website and to improve content and performance. GA4 may collect device information, pages viewed, events, session statistics, approximate location (city/region-level), and technical identifiers (e.g., Client ID). IP addresses are processed with IP anonymization enabled. Data is aggregated and does not identify individuals.

  • Cookies / Storage: GA4 uses cookies or storage technologies to distinguish users and sessions.
  • Retention: We retain GA4 event-level data for the minimum period necessary (e.g., 2–14 months) and rely on aggregated reports thereafter.
  • Opt-out: You can disable Analytics via your browser settings, ad settings, or by using the Google Analytics Opt-out Add-on. Where available, our site also honors consent preferences surfaced by your browser or our consent banner.

Google Search Console

We use Google Search Console to monitor website indexing status, search performance (e.g., queries, impressions, click-through rates), and technical coverage issues. Data provided by Search Console is aggregated by Google and used to diagnose and improve our site’s discoverability. Site ownership may be verified via DNS, HTML tag, or other non-identifying methods. We do not combine Search Console data with personal information for user profiling.

For more information, please see Google’s policies and documentation regarding how Google uses information from sites or apps.

Changes to This Policy

We may update this policy from time to time. Updates will be posted at this same link. Where legally required, we will obtain your consent.
