My cards are only on this device
Open Library → Backup & export to save an editable JSON backup. Keep it outside the app. A local backup is useful before reinstalling or changing devices.
Can I use my China account?
The international app has separate accounts, cloud storage, purchases, and Community content. It can be installed alongside the China app. China accounts and purchases do not automatically transfer.
Are purchases enabled in this beta?
No. This internal beta includes the Free allowance of 40 cloud cards and 100 MB. Pro pricing is still planned.
Where do I cancel an existing Apple subscription?
