For parents and guardians

WonderCanvas Support

For help with the iPad app, contact developer fangjie hu at 360524430@qq.com. A parent or guardian should contact us; please do not attach children's recordings or personal identifiers.

Restore an existing subscription

Open Parent Settings, complete the parental gate, then choose View Membership Plans → Restore Purchases. Use the Apple Account that made the purchase. Check Apple's subscription record before attempting another purchase.

Manage renewal or a trial

Use Manage Subscriptions in Parent Settings, or iPad Settings → Apple Account → Subscriptions. Uninstalling the app or withdrawing cloud consent does not cancel renewal. Apple's purchase sheet and subscription settings govern regional pricing, trial eligibility and billing dates.

Start voice creation

A parent must first confirm the cloud notice and allow microphone access. If you release during first-time setup, press and hold again afterwards; speak once recording is active. Release to transcribe, review the text, then confirm generation. Recordings are limited to approximately 60 seconds. Typing is also available.

Generation failures and weekly usage

Keep your current artwork, check the network and retry without repeated taps. Basic allows 10 successful generations per week; Plus allows 30. Quotas replenish on Monday according to the device's calendar week, without rollover. The app counts an accepted successful image, not a failed request, timeout or safety refusal. A transmitted request may still consume provider usage if interrupted.

Back up and print artwork

Export finished artwork as PNG from its detail page to Files. In Parent Settings, Print Black-and-White Line Art exports the current original line drawing as an A4 PDF. Export important artwork before uninstalling or changing devices; developer-operated gallery cloud sync is not provided.

Withdraw cloud consent

Disable Cloud Voice or choose Withdraw Cloud AI Consent in Parent Settings. Withdrawal cancels current requests and clears the local consent record, without deleting local artwork. New uploads require a new parental decision. Local drawing does not upload artwork or recordings, but remains subject to subscription entitlement. Withdrawal does not cancel Apple billing or erase records the provider must retain.

When requesting help, include app version, iPad model, iPadOS version, steps to reproduce and network type. Redact screenshots; never send API keys, passwords, full receipts or children's private information. For privacy requests, specify the request type and approximate time of use. Provider-side requests depend on applicable law and the ability to identify the relevant invocation.
