CardFlow Privacy Policy

CardFlow is a standalone creative workspace. We do not run our own servers, do not embed trackers, and cannot read your content.

Information We Handle

• Your cards, media, and tags live on your devices. Sync happens only through Apple’s CloudKit when you turn it on.
• Apple ID and purchase info are processed by Apple; CardFlow never sees your credentials.
• Debug logs are received only if you manually send them via email.

How Data Is Used

• Render and organize your projects locally.
• Sync changes between your own devices via iCloud private databases.
• Import assets using system pickers; processing stays on device.

Storage & Security

• Device-first storage with full deletion/export control.
• iCloud provides encrypted transport and storage managed by Apple.
• No CardFlow-operated servers, so we cannot monetize, mine, or transfer your data.

Third-Party Services

Only Apple services (CloudKit, App Store billing) are integrated. No analytics SDKs, ads, or social logins.

Your Choices

• Delete everything by removing the app or disabling iCloud for CardFlow.
• Export content via the iOS share sheet today; full export tools are on our roadmap.
• Use CardFlow offline at any time—nothing is uploaded automatically.
