This Privacy Policy explains how information is handled when you use HanziSeed on Apple platforms. By using the App, you agree to this Policy.
1. Summary
- We do not require an account.
- We do not use advertising or cross-app tracking.
- Learning progress is stored locally on your device (e.g., SwiftData / preferences).
- Photo library access is used only if you choose a profile photo, stored on device.
- We do not operate a backend that collects children’s learning profiles for this App.
- Optional online features may send text to a translation API or fetch public stroke-order data.
- Purchases are processed by Apple.
2. Who the App Is For
HanziSeed is an educational Chinese character / vocabulary learning app intended for students and families. Parents or guardians should supervise children’s use and manage purchases with their Apple ID.
We design the App to keep core learning data on device and to avoid collecting personal information from children for advertising or profiling.
3. Information We Process
3.1 Learning data (on device)
The App may store locally:
- Lesson progress, scores, unlock state
- Dictation / challenge results
- Mistake book items
- Preferences and premium entitlement flags
This data stays on the device unless you delete the App or clear App data. We do not sync it to our own cloud servers.
3.2 Profile photo (optional)
If you grant Photo Library access and choose a profile image, the image is used for the in-App profile display and remains on device. We do not upload profile photos to our servers.
3.3 Optional network features
Depending on the feature you use, the App may:
- Send a text string to a third-party translation service (currently MyMemory) for meaning lookup
- Fetch stroke-order / character drawing data from a public CDN (e.g., jsDelivr / hanzi-writer-data)
- Contact Apple for In-App Purchase product info, purchase, and restore
Do not enter names, addresses, phone numbers, school IDs, or other personal details into free-text fields that may be translated online.
3.4 Purchases (Apple)
Subscriptions (monthly / yearly) and lifetime unlocks are billed by Apple via StoreKit. We receive entitlement status through Apple. We do not receive your full payment card details.
3.5 Support communications
Emails to support@hanworks.online include your email address and message content so we can help you.
4. Information We Do Not Collect
We do not intentionally:
- Require registration with name, birthday, or school information
- Sell personal information
- Use advertising SDKs or cross-app tracking
- Upload children’s learning profiles to our servers
- Collect precise location for advertising
Our App Privacy Manifest declares that we do not track and do not collect the listed data types for this App.
5. How We Use Information
| Data | Purpose |
|---|---|
| Local learning data | Provide lessons, practice, reports, and progress |
| Profile photo | Optional avatar display |
| Text sent for translation | Show meanings when local data is insufficient |
| Stroke-order CDN requests | Show handwriting stroke animations |
| Apple purchase data | Unlock paid features / restore purchases |
| Support email | Customer support |
6. Sharing
We do not sell personal information.
We may share limited information only with:
- Apple — purchases and platform services
- Translation / CDN providers — only the technical request needed for a feature you use
- Legal recipients — when required by law or to protect rights and safety
7. Children’s Privacy (COPPA / similar laws)
We do not knowingly collect personal information from children under 13 (or the equivalent age in your region) for commercial profiling or advertising.
- Core learning data is stored on the device.
- We ask parents/guardians not to submit children’s personal identifiers via support email or into online translation inputs.
- If you believe we have received a child’s personal information, contact support@hanworks.online and we will delete it when appropriate.
Purchases should be made by a parent/guardian using their Apple ID, with appropriate Screen Time / Ask to Buy controls enabled.
8. Data Retention
- On-device learning data and profile photos remain until you delete them or uninstall the App.
- Third-party translation/CDN providers may retain request logs under their own policies.
- Support emails are retained only as needed to handle your request.
9. Security
We design the App around local storage for learning progress. No method of storage is 100% secure. Protect the device with a passcode and keep the Apple ID secure.
10. International Users
Optional translation/CDN requests and support email may be processed in other countries. Mandatory local privacy rights remain available as required by law (including, where applicable, rights of access, deletion, and objection).
11. Your Choices and Rights
You may:
- Delete the App to remove local App data from the device
- Revoke Photo Library permission in iOS Settings
- Manage or cancel subscriptions in Apple ID → Subscriptions
- Contact support@hanworks.online regarding personal data in support emails
Where applicable law grants additional rights, contact us and we will respond as required.
12. Changes
We may update this Policy and will revise the “Last updated” date. Continued use after changes means you accept the updated Policy, except where law requires otherwise.
