Privacy Policy

Last updated: 3 November 2026

This policy describes the current website at gorosjapaneselab.com, operated by Goro’s Japanese Lab. Contact: gorosjapaneselab@gmail.com.

Learning data stored on your device

The app uses browser local storage, session storage, IndexedDB and caches to remember preferences, recent quiz results, saved mistakes, downloaded resources and unfinished mock tests, including answers and timing information. These records belong to that browser and website address; they do not automatically sync across devices or between the old and new website addresses.

You can remove them through your browser’s site-data settings. Doing so can erase your progress, preferences and unfinished tests. Some features also provide their own history or mistake-clearing controls.

Usage statistics

Our own analytics sends activity information to our Cloudflare-hosted service: pages or activities opened, quiz starts and completions, score percentages, time spent, device platform, visit time, referring website hostname, campaign labels and a random session identifier. Browser storage remembers whether you have visited before and queues up to 100 events when delivery fails; queued events are retried when connectivity returns.

Cloudflare supplies an approximate country code. The application stores daily aggregate counts and score/time totals for understanding usage and improving activities. It does not save individual answer choices in those aggregate statistics, or store the random session identifier in the aggregate database. No automatic expiry is currently configured for the daily aggregates.

Hosting and external services

Cloudflare hosts and delivers the website and learning resources. Network requests necessarily expose connection information such as your IP address and browser information to the service provider. Our application’s aggregate analytics database does not store raw IP addresses.

The app requests optional fonts from Google Fonts. Your browser connects to Google when loading those fonts. See Cloudflare’s Privacy Policy and Google’s Privacy Policy for their processing practices.

Email enquiries

If you email us, we receive your email address, message and any attachments through Gmail. We use these to handle your enquiry and corrections. Do not include sensitive information. Enquiries do not have an automatic deletion schedule; you may contact us to request deletion, subject to records we need to retain.

Advertising and cookies

The current website does not load Google AdSense or Google Analytics. The app uses browser storage for the purposes described above and does not set advertising cookies itself. Infrastructure providers may process requests under their own policies.

If advertising is introduced, we will update this policy and configure the applicable advertising disclosures and consent controls before enabling it.

Your choices and requests

You can manage site storage and external resources in your browser and contact us about access, correction or deletion of information you have provided. Device-local learning data must be managed on your device; aggregate statistics generally cannot be linked back to a particular visitor.

Updates will be published on this page with a revised date.
