Privacy Policy

Last updated: April 29, 2026

This Privacy Policy describes how Study Hiragana (“we”, “our”, “the site”) collects, uses, and discloses information about you when you visit studyhiragana.com. The same policy applies to our companion site, the other of studyhiragana.com / studykatakana.com.

1. Information We Collect

You do not need to create an account or provide personal information to use this site. The following information is collected automatically:

• Usage data on your device: pages visited, characters practiced, and progress through lessons. This is stored locally in your browser using localStorage and stays on your device — we do not receive a copy.
• Anonymous analytics: aggregate usage information (page views, session duration, approximate country) collected via Google Analytics.
• Advertising data: when third-party advertising is enabled, anonymous identifiers used to serve and measure ads.

2. Cookies and Local Storage

The site uses browser localStorage to remember your progress, theme preference, and settings between visits. Clearing your browser storage will reset your progress.

Cookies are set by Google Analytics and (when enabled) Google AdSense for analytics and advertising purposes.

3. Third-Party Services

We use the following third-party services, which may set their own cookies and process information about you:

• Google Analytics — anonymous traffic analytics. See Google’s privacy policy.
• Google AdSense — third-party vendor that may use cookies (including the DoubleClick DART cookie) to serve ads based on your visits to this and other sites. You can opt out of personalized advertising at any time via Google Ads Settings or www.youradchoices.com.

4. How We Use Information

• To save your learning progress locally on your device.
• To understand how the site is used in aggregate, so we can improve it.
• To serve relevant advertising when ads are enabled.

5. Data Sharing

We do not sell, rent, or share personal information with third parties beyond the service providers listed above (Google Analytics, Google AdSense). Those services operate under their own privacy policies.

6. Your Choices

• Clear all locally stored progress by clearing your browser’s site data for this domain.
• Opt out of Google Analytics by installing the Google Analytics opt-out browser add-on.
• Opt out of personalized advertising via Google Ads Settings.

7. Children’s Privacy

This site is intended for general audiences and does not knowingly collect personal information from children under 13. We do not require account creation, and progress is saved only in the local browser.

8. Changes to This Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top of this page reflects the most recent revision.
