End-to-end private iCloud sync.
Your collection follows you across every Mac signed into the same Apple ID. Apple's CloudKit private database carries your data end-to-end — Apple cannot read it, we cannot read it. There is no Card Curator backend between your Macs.
How sync works.
Sign into the same Apple ID on each Mac, enable iCloud for Card Curator, and your collection appears. No accounts to create with us. No password to remember besides the one you use for your Apple ID.
Sign into iCloud
On each Mac, sign into the same Apple ID. Make sure iCloud Drive is enabled for Card Curator under System Settings → Apple ID → iCloud.
Open Card Curator
Cards, Spaces, binders, themes, and trades begin syncing automatically. The Sync Health panel in Settings shows last sync time and any warnings.
Edit on any Mac
Scan a card on your MacBook. It appears on your iMac. No manual export, no merge step.
Recover from any Mac
Wiped a Mac? Set up the new one, sign into the same Apple ID, install Card Curator, and your collection rehydrates. Local backups in Settings → Backups give you a second safety net.
Built directly on Apple's CloudKit.
Card Curator does not run a backend that sees your data. Sync happens between your Macs through Apple's CloudKit private database. The Sync Health monitor watches for stalls, paused-sync states, and quota warnings, and surfaces them in Settings.

Frequently asked.
How does iCloud sync work?
Card Curator uses Apple's CloudKit private database. As long as your Macs are signed into the same Apple ID and iCloud Drive is enabled for Card Curator, your collection flows between them automatically. Apple cannot read it; we cannot read it; only you and your other Macs can.
Do I pay extra for sync?
No. iCloud sync is included with your one-time license purchase. There is no per-month sync fee from Card Curator. (Apple's free iCloud tier covers most card collections; very large libraries may need a paid iCloud+ tier from Apple — Apple's pricing, not ours.)
Is my data encrypted in transit?
Yes. CloudKit uses end-to-end private encryption between your Macs. Apple cannot decrypt the contents of the private database. We do not run a backend that touches your data.
What if iCloud is disabled?
Card Curator works fully offline. iCloud sync is optional. With iCloud off, your collection stays on the one Mac and never syncs anywhere.
Will it sync to the iOS companion?
Yes, when the iOS app ships in late 2026. The same Apple ID, the same iCloud private database — your Mac collection appears on iPhone and iPad automatically.
Are local backups still useful with sync on?
Yes. Card Curator runs automatic local backups on launch with a retention policy. Local backups protect against accidental deletes that would otherwise propagate through sync. Cloud + local is the durable combo.
One price. Every feature. Forever.
Card Curator launches publicly in October 2026 at $59.99 USD — one-time purchase, perpetual license. Sync to every Mac you own at no extra cost.
