## What is Card Master?

Card Master turns paper business cards into a searchable, private network on your iPhone. Korean, Japanese, English and Traditional Chinese interfaces are included.

ON-DEVICE CARD RECOGNITION
Take a photo, import from Photos, or use document scanning. Adjust corners, rotate and preview before recognizing with Apple Vision. Review important details against the original image. Organize names, companies, job titles, phones, email and addresses, plus LINE/WhatsApp details, tax IDs and multiple contact fields. Core OCR requires iOS 17 or later, not Apple Intelligence. No external AI service is used.

ORGANIZATION AND PRIVATE CARDS
Create groups, favorites, tags and notes; search and review duplicates. Lock selected cards with Face ID, Touch ID or your device passcode. Private cards and groups stay separate from the regular library. Saving a card never automatically adds it to iPhone Contacts; you choose when to export it.

FREE CALENDAR INTEGRATION
Record when and where you met and plan your next visit. Open Apple's native event editor inside Card Master, create or link calendar events, and return to edit them from the card. Configure recurrence and reminders. Calendar access is requested when needed; events may sync through your chosen calendar account.

RELATIONSHIP MAP — LIFETIME UPGRADE
Explore shared companies, regions, industries and confirmed products/services, or add relationships manually. Shared attributes do not mean that people know each other. On supported iOS 26+ devices with Apple Intelligence and its on-device model available, optional industry suggestions can assist classification. You confirm suggestions before saving. Manual classification and rule-based connections remain available without AI.

ENCRYPTED BACKUPS AND PERSONAL ICLOUD
Local encrypted backup and restore are free. The lifetime upgrade adds optional encrypted backup and restore through your own iCloud. This is manual backup, not live multi-device sync. An Apple account, iCloud Drive and sufficient storage are required. Save the recovery code separately; it is not uploaded and support cannot recover a lost code.
Manage backup files in Files > iCloud Drive > 人脈大師 > EncryptedBackups. Deleting a cloud backup does not delete your cards in the app. VCF/CSV exchange is also available; exported plaintext files are not protected by the private-card lock.

ONE PURCHASE, LIFETIME ACCESS
The free version includes ads, scanning, organization, groups, private cards, local backups and calendar tools. The existing non-consumable lifetime purchase removes ads and unlocks maps, Relationship Map and iCloud backup/restore. Existing purchasers receive the new features without buying again. Restore Purchases is available. No subscription; StoreKit displays your local price.

Core recognition, editing and search work offline without an app account. Card content is not sent to external AI, ad networks or our own servers. Ads, purchases and iCloud backup require internet access. Ad services may process device, network and interaction data. Restoring purchases does not restore card data.

NEW IN 1.5
Japanese card parsing, department and name-reading fields, and per-card region hints. Unknown family/given names are not guessed. Configure phone extensions with adjustable pauses, preserved in Contacts and vCard. Back photos are optional: save the front alone and add the back later. Review product/service suggestions from the original text before using them in search or the paid relationship map.

NEW IN 1.5.1
A Korean interface and Korean business card parsing, with improved suggestions for names, companies, departments, addresses, phones and extensions. Korean CSV headers, contact exports and regional grouping in the Relationship Map are supported. Verify OCR suggestions against the original card.
