User Guide & Security Support

Thank you for choosing Card Master. We operate strictly on-device with optional encrypted personal iCloud backups. Here is your essential guide to smooth operation and data security:

1. Recognition & Proofreading

Card Master processes text directly using Apple's on-device neural framework. Recognition does not upload card images or text. You may choose to export data or create an encrypted personal iCloud backup. For best results, ensure good lighting and avoid glare. You can tap recognized text blocks in the editor to quickly assign them to name, phone, or company fields.

2. Face ID & Touch ID Private Vault

Ensure your iPhone has a device passcode configured before using private cards. Once locked, sensitive cards can only be viewed after biometric or passcode verification. The app automatically locks upon entering the background or after 60 seconds of idle time.

3. Device Migration & Encrypted Backups

Because we do not maintain a cloud database, when upgrading to a new iPhone, export an Encrypted Backup in Settings and save the unique 256-bit Recovery Code. Enter this code on your new iPhone to restore your cards in seconds. Without the Recovery Code, our support team cannot decrypt your data.

4. Lifetime Ad Removal & Restoring Purchases

Ad removal is a one-time non-consumable purchase (US$5.00 in the US; local prices are shown in the app), not a recurring subscription. On a new device, tap "Restore Purchases" under Settings with your Apple ID to regain lifetime ad-free status and maps, Relationship Map and encrypted personal iCloud backups. Calendar editing remains free.

5. Contact Support

If you encounter issues or have questions, contact us directly at mkjohnny@gmail.com.
For your privacy, do not email client business cards, confidential details, or backup recovery codes.

Your data, your choice

Available in 1.5: In-app Apple calendar editing, event linking and follow-up planning are free. The existing lifetime upgrade includes Relationship Map and encrypted personal iCloud backup/restore at no additional purchase. Local encrypted backups remain free. iCloud backup is initiated by you, requires an Apple account, iCloud Drive and storage, and is not live sync. Only encrypted files are uploaded; recovery codes are not. Keep your recovery code separately; support cannot recover it. Delete backups in Files > iCloud Drive > 人脈大師 > EncryptedBackups, then remove them from Recently Deleted for permanent removal. Deleting a backup does not delete local cards; deleting the app does not delete cloud backups. Shared attributes in Relationship Map do not establish that people know each other. Optional Apple Intelligence industry suggestions process company and job title on-device and require your confirmation. Full calendar access is requested on demand to retrieve/edit user-linked events; events follow your calendar account sync settings. Reminders is not accessed.

New in 1.5: Japanese, extensions and optional card backs

Use English, Traditional Chinese or Japanese, with a country/region hint for each card. Keep departments and name readings. Add phone extensions and dialing delays: one comma pauses for 2 seconds, two for 4 seconds, with pauses preserved in Contacts and vCard. Capturing the back is entirely optional: save the front alone or add the back later. Recognize second-language text and product details on-device, then review and confirm products/services for search. The lifetime Relationship Map can show shared confirmed products; shared attributes do not mean two people know each other.

Requires iOS 17 or later. Apple Vision OCR does not require Apple Intelligence. Optional industry suggestions require a supported iOS 26+ device, supported language and an available Apple Intelligence on-device model. Manual organization remains available. No external or cloud AI is used. Ads, purchases and user-initiated encrypted personal iCloud backups require a connection.
