プライバシーポリシー

Last updated: April 2026

Data We Collect

KotobaaNavi uses Google Analytics 4 (GA4) to understand how visitors use this site. GA4 collects anonymized usage data such as pages visited, session duration, and general location (country or region level). This data helps us improve the site's content and features. We do not collect personally identifiable information such as your name, email address, or precise location.

Cookies and localStorage

We use two types of client-side storage on this site:

Google Analytics cookies — These are set by Google Analytics 4 to track anonymous usage patterns across sessions. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.
localStorage — We save your learning progress, quiz state, bookmarks, XP, and theme preference in your browser's localStorage. This data never leaves your device and is never transmitted to any server. You can delete it at any time by clearing your browser's site data for kotobanavi.com.

Google AdSense Advertising

KotobaaNavi displays advertisements served by Google AdSense. Google and its partners may use cookies to show you ads that are relevant to your interests, based on your browsing activity across websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and other sites on the internet.

You can opt out of personalized advertising at any time by visiting Google Ad Settings. You can also opt out of third-party vendor cookies for personalized advertising via the Network Advertising Initiative opt-out page.

Third-Party Links

Some pages on KotobaaNavi may contain links to external Japanese language resources, dictionaries, or reference materials. These links are provided for educational purposes only. We are not responsible for the content or privacy practices of any third-party websites. We encourage you to read the privacy policy of any external site you visit.

Your Rights and Data Control

Because we do not collect or store personal data on our servers, there is no account to delete. To remove all locally stored learning data (progress, bookmarks, quiz history), open your browser settings and clear site data for kotobanavi.com. This will permanently erase all localStorage data stored on your device.

If you have any questions about this privacy policy or how your data is handled, please contact us at formyrahul@yahoo.com. We will respond to all genuine enquiries promptly.

Changes to This Policy

We may update this privacy policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. The date at the top of this page indicates when the policy was last revised. Continued use of KotobaaNavi after any changes constitutes your acceptance of the updated policy.
