Copybook Club is a Chinese handwriting worksheet generator for iPad and iPhone.
This Privacy Policy explains what information is processed locally, what information may
be received if you contact us, and how Apple services such as App Store purchases or reviews
may be involved.
1. Overview
Copybook Club is designed to work locally on your device. You can create Chinese handwriting
worksheets, preview them, export clean A4 PDFs, and practice with Apple Pencil on iPad without
creating a user account.
We do not operate a Copybook Club account system, user profile system, cloud sync service,
or user worksheet database.
2. Information processed locally on your device
The following information is processed locally on your device as part of normal app use:
- Chinese text that you enter or paste into the app;
- worksheet settings, such as grid, font, character size, repeat count, and trace/fade style;
- generated worksheets and saved worksheet items inside the app;
- clean PDF worksheets that you choose to export;
- local app preferences and settings.
This information is not sent to Copybook Club servers. Copybook Club does not provide device-to-device
sync in the current version.
3. Apple Pencil practice
Apple Pencil practice is temporary and local. When you write on a worksheet with Apple Pencil,
the handwriting is used only for on-device practice during that session.
Apple Pencil handwriting is not sent to Copybook Club servers and is not saved into exported PDFs.
If you close and reopen the worksheet, it opens as a clean worksheet again.
You may use your device’s built-in screenshot or screen recording features if you want to save
your practice manually. Those features are controlled by your device and operating system, not by
Copybook Club.
4. Information we do not collect
In the current version, Copybook Club does not collect the following through its own app systems:
- user accounts, usernames, or passwords;
- your name, age, or profile information;
- your custom Chinese text;
- your generated worksheets;
- your Apple Pencil handwriting;
- advertising identifiers for tracking;
- third-party analytics data from SDKs such as Firebase, Amplitude, Mixpanel, or similar tools;
- third-party crash-reporting data from SDKs such as Sentry or similar tools.
5. Bug reports and support emails
If you contact us by email or use the app’s “Report a Bug” option, we receive only the information
you choose to send.
This may include your email address, message, screenshots, screen recordings, device model,
iOS or iPadOS version, app version, and a description of the issue.
We use this information to understand your request, troubleshoot the issue, and respond to you.
6. App Store purchases and reviews
If Copybook Club offers paid features, subscriptions, or one-time purchases, payments are processed
by Apple through the App Store and Apple In-App Purchase system.
Copybook Club does not receive or store your payment card number or banking details.
If the app asks you to leave a review, the review flow is handled through Apple’s system according
to Apple’s rules. Reviews are submitted to the App Store, not directly to Copybook Club.
7. Data sharing
We do not sell your personal data. We do not share your custom Chinese text, generated worksheets,
or Apple Pencil handwriting with third parties, because this content is not sent to Copybook Club
servers.
If you contact us by email, your message may be processed by our email provider for the purpose of
delivering and managing support correspondence.
8. Data retention
Local app data remains on your device until you delete it in the app, if deletion controls are available,
or until you delete the app from your device.
Support emails and bug reports may be kept for as long as reasonably needed to respond to your request,
maintain support records, troubleshoot issues, and protect the integrity of the service.
9. Your choices
You can choose not to contact support or not to send a bug report. If you do send a report or email,
please avoid including information that is not needed to understand the issue.
You can delete local app data by deleting saved worksheets where available, or by deleting the app from
your device. You control where exported PDFs are saved or shared after export.
10. Children’s privacy
Copybook Club is not specifically directed to children. The app does not require user accounts and does
not knowingly collect personal information from children through its own account or server systems.
If you believe a child has sent personal information to us through a support email or bug report,
please contact us so we can review and delete it where appropriate.
11. Changes to this policy
We may update this Privacy Policy from time to time. If we make changes, we will update the “Last updated”
date at the top of this page.
