Privacy Policy

Established: June 27, 2026  |  Last Updated: June 29, 2026

The developer of "World Weirdos: Flags & Laws" (hereinafter referred to as the "App") is committed to protecting the privacy of all our users. This Privacy Policy explains what information we collect, how we use it, and the choices you have regarding your information. Please read this policy carefully before using the App.

1. Information We Collect

During normal use of the App, we do not directly collect, store on our servers, or transmit personally identifiable information such as your name, phone number, or precise location to any external server operated by us.

However, for the purpose of responding to inquiries, we collect your email address and the content of your inquiry through the contact form. The collected information will be used solely for responding to and handling your inquiries, and will not be used for any other purpose.

The following data is stored exclusively on your device (via SwiftData local database and device UserDefaults / AppStorage) and is never transmitted to or stored on our servers:

  • Quiz clear status, scores, star ratings, and level progress
  • Favorited laws, manners, and trivia entries
  • Selected language preference (Japanese, English, Chinese, German)
  • Pro feature purchase state (stored in AppStorage)
  • In-App Review request completion flag

2. Third-Party Services & SDKs

The App integrates the following third-party services and SDKs for advertising, in-app purchase processing, and advertising attribution. Each of these third parties may automatically collect and process certain non-personally identifiable information (such as device identifiers, advertising identifiers, purchase data, and usage statistics) in accordance with their own privacy policies.

  • Google AdMob (Google LLC)
    Purpose: Displaying banner and inline advertisements to non-Pro users.
    Data Collected: Advertising identifiers (IDFA / GAID), IP address, device information (OS, device model, screen size), app usage data, ad impressions and clicks, diagnostic information.

    Privacy Policy: https://www.apple.com/legal/privacy/

3. Advertising Identifier (IDFA) & App Tracking Transparency (ATT)

The App may use Apple's Identifier for Advertisers (IDFA) for the purpose of delivering more relevant advertisements. Starting with iOS 14.5, accessing the IDFA requires your explicit permission under Apple's App Tracking Transparency (ATT) framework.

You may be shown a system dialog asking whether you want to allow tracking across apps and websites owned by other companies. If you decline, the App's core features remain fully available, and you will be served non-personalized ads instead.

You can change your tracking preference at any time by going to your device's Settings → Privacy & Security → Tracking.

4. Advertising Attribution (SKAdNetwork)

The App uses Apple's SKAdNetwork (Stock-Keeping Attribution Network) framework to measure the effectiveness of our advertising campaigns.

SKAdNetwork is a privacy-preserving attribution framework developed by Apple. It allows us to receive aggregated, anonymized data about app installs and in-app events resulting from our ad campaigns. This framework has the following privacy characteristics:

  • It does not collect or share any personally identifiable information.
  • All data is aggregated and anonymized by Apple before being reported to us.
  • It operates independently of your ATT consent status, and never includes individual user-level data.
  • It does not enable tracking of your activity across other apps or websites.

5. Cookies and Similar Technologies

The App itself does not use cookies. However, integrated third-party services (in particular, Google AdMob) may use device identifiers and similar technologies for the purposes of ad delivery and performance measurement. Please refer to each service provider's own privacy policy for more details.

6. Children's Privacy

The App is not directed to children under the age of 13 (under the U.S. COPPA standard) or 16 (under the EU GDPR standard). We do not knowingly collect personal information from children under 13. If a parent or guardian discovers that their child has provided personal information, please contact us via the Contact page, and we will promptly address the situation.

  • Right of Access: The right to request a copy of the personal data we hold about you.
  • Right to Rectification: The right to request correction of inaccurate data.

8. Data Retention

We do not retain any user personal data on our own servers. All local data stored on your device (quiz progress, favorites, etc.) is permanently erased when you uninstall the App. For data collected by third-party SDKs, please refer to each provider's respective privacy policy for their data retention practices.
