Support and privacy information for Caiyun Handwriter on iPhone and iPad.
Caiyun Handwriter is a handwriting notebook for iPhone and iPad, developed by Ling Shen. Write notes in your own handwriting, customize your pen, and share notes as images.
For help, bug reports, or purchase questions, email forrest.lingshen@gmail.com. Include your app version, device model, iOS/iPadOS version, and the steps that led to the problem. Screenshots are helpful, but please remove private information first. Never send passwords or payment-card details.
You can keep up to five notes for free. Deleting a note frees a slot. Unlimited Notes removes this limit with a one-time in-app purchase; it is not a subscription. The price shown in Apple’s purchase confirmation applies.
To purchase or restore the unlock, open More → Unlimited Notes. Use Restore Purchases with the Apple Account used for the original purchase. An internet connection may be needed. Restore Purchases restores the unlock, not your notes.
Existing notes remain available to read, edit, share, and delete without purchasing. Purchase availability may vary by App Store region.
Notes are stored locally on your device. This version has no app-provided cloud synchronization. Do not delete the app if it contains your only copy of important notes. You can share important notes as images, but these exported images are not an editable-note backup or an import format.
Your device’s backup settings may affect whether app data is included in an Apple device backup. We do not operate a server that can recover your notes.
Open the note, tap its share button, and choose an option in the system share sheet. Check the exported image before sending it. Saving to Photos may require permission from iOS.
If the unlock does not appear, check that the purchase completed, connect to the internet, and try Restore Purchases. For billing or refund requests, use Apple’s purchase support. Please do not purchase again just to troubleshoot.
