Privacy Policy

Last updated: April 2026

1. Who we are

HanTales is a Chinese language learning app available at hantales.com. If you have any questions about this policy, please contact us at harryjamesknott@gmail.com.

2. What data we collect

When you sign in with Google, we receive your name, email address, and profile picture. We store your email and name in our authentication system, powered by Supabase.

As you use HanTales, we also store the following:

  • Reading progress — which stories you have completed and when
  • Vocab bank — words you have saved, including the example sentence they came from and your spaced repetition learning data
  • Study sessions — dates and summary statistics of your flashcard review sessions
  • Settings — your app preferences such as display mode

3. How we use your data

We use your data solely to provide the HanTales service — to remember your progress, sync your vocab bank across sessions, and personalise your learning experience. We do not use your data for advertising and we do not sell it to third parties.

4. Cookies and consent

HanTales uses cookies to provide a functional and personalised experience. You can manage your preferences at any time using the cookie settings button (🍪) on our site.

  • Essential Cookies: Strictly necessary for the app to function. They handle secure login via Supabase and remember your light/dark mode preference. These cannot be disabled.
  • Analytics Cookies: If you opt in, we use Google Analytics to understand how HanTales is used — for example, which stories are most popular. Google Analytics may set cookies such as _ga and _ga_XXXXXXXX on your device. You can opt out or withdraw consent at any time.

For full details of every cookie we use, see our Cookie Policy.

5. Third parties

We use the following third-party services to operate HanTales:

  • Supabase — database and authentication (supabase.com)
  • Google OAuth — sign-in (google.com)
  • Google Analytics — usage analytics, only if you consent (analytics.google.com)
  • Google Cloud Text-to-Speech — generating audio for stories. This processes story text only, not any personal data.
  • Vercel — website hosting (vercel.com)

Each of these services has its own privacy policy.

6. Data retention

We retain your data for as long as your account is active. If you would like your data deleted, please contact us at harryjamesknott@gmail.com and we will remove it promptly.

7. Your rights

Under UK GDPR you have the right to access, correct, or delete the personal data we hold about you. To exercise any of these rights, please contact us at the email above.

8. Changes to this policy

We may update this policy from time to time. Any changes will be posted on this page with an updated date.
