Privacy Policy

Hi! We are Yibai Online (Yunhe Qu Yibai Wangluo Bianlidian). We care about your privacy and want to be as clear as possible about how our apps (like Hanzi Writer) handle your data.

1. Your Data

We like to keep things simple: we don't want your personal data unless it's absolutely necessary.

• Offline first: Most of your learning progress and settings stay right on your phone. We don't see it and we don't track it.
• Accounts: If you create an account to sync your data, we'll save your email address and basic profile info to keep your account secure.

2. Services we use

To make the app work smoothly, we use a few trusted partners:

• Login: We use Supabase to handle accounts and keep your login safe.
• Payments: All purchases go through the Apple App Store or Google Play Store. We use RevenueCat to manage subscriptions, but we never see your credit card info.
• Ads: In the free version, we might show ads using Google AdMob. They might use a unique ID from your phone to show ads that are relevant to you.

3. Security

We do our best to keep your information safe. While no app is 100% unhackable, we use modern tools and industry standards to protect your account.

4. For Parents and Kids

We welcome learners of all ages! Because we don't collect personal information from our users (most data stays on your device), our apps are safe for children. If you are a parent and have any questions about how we keep things safe, please feel free to reach out.

5. Contact us

If you have any questions, just email us at [email protected].
