Privacy Policy

Introduction

Hane (“we”, “our”, or “us”) is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the Hane mobile application.

Information We Collect

• Account Information: When you sign in with Apple or Google, we receive your name and email address (if you choose to share them). Apple Sign-In allows you to hide your email using a private relay address.
• Learning Progress: Your kanji study progress, quiz scores, game results, vocabulary mastery levels, and streak data are stored to personalize your learning experience.
• App Preferences: Settings such as theme preference, notification preferences, and display options.
• Usage Data: Anonymous analytics about which features you use to help us improve the app.

iCloud Sync

If you enable iCloud Sync, your learning progress and preferences are stored in your private iCloud account using Apple's CloudKit framework. This data is encrypted and only accessible by you through your Apple ID. We do not have access to your iCloud data.

In-App Purchases

Subscription and purchase data is handled entirely by Apple through the App Store. We receive confirmation of your subscription status but do not process or store payment information such as credit card numbers.

Third-Party Services

• Apple Sign-In: Authentication is handled by Apple. See Apple's privacy policy at apple.com/privacy.
• Google Sign-In: If you sign in with Google, authentication is handled by Google. See Google's privacy policy at policies.google.com/privacy.
• Apple App Store: Subscription billing and management is handled by Apple.

Website Analytics

On this website (hane-app.com), we use PostHog to measure page views and clicks on download links. Analytics data is processed exclusively in PostHog's EU cloud (Frankfurt, Germany). The analytics run in cookieless “memory mode”: no cookies are set and nothing is stored on or read from your device, so visitors are not recognized across visits and no consent banner is required. Processed data includes the page visited, referrer, browser and device type, and your IP address for approximate geographic attribution. The legal basis is our legitimate interest in improving the website (Art. 6(1)(f) GDPR). For details, see our cookie statement.

Launch Notification Emails

You can leave your email address on this website to be notified when Hane launches on the App Store. Signup uses double opt-in: we send a confirmation email first, and only confirmed addresses are added to the list. The legal basis for this processing is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time via the unsubscribe link in any email or by contacting us. We use this address only to send launch news and delete it after the launch notification or when you unsubscribe.

We use Brevo (Sendinblue SAS, 7 rue de Madrid, 75008 Paris, France) as our processor to store the list and send these emails. Your address is processed on servers in the EU. See Brevo’s privacy policy for details.

Data Storage & Security

Your learning data is stored locally on your device and, if iCloud Sync is enabled, in your private iCloud container. We use industry-standard security measures to protect your information. Local data is stored in an encrypted SQLite database.

Data Retention & Deletion

• You can reset your learning progress at any time from Settings.
• You can delete your account and all associated data by signing out and resetting all progress in Settings.
• If you delete the app, all locally stored data is removed. iCloud data can be managed through your device's iCloud settings.
• To request complete data deletion, contact us at hello@hane-app.com.

Children's Privacy

Hane is suitable for users of all ages. We do not knowingly collect personal information from children under 13 beyond what is necessary for the app's educational functionality. If you are a parent or guardian and believe your child has provided personal information, please contact us at hello@hane-app.com.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the “Last updated” date at the top of this policy. Continued use of the app after changes constitutes acceptance of the updated policy.
