Frequently asked questions

Do I need to register or sign in?

No. Just open the app and start — no account, no email required.

Is my card data uploaded to the cloud?

By default, no. All card details and front/back images are stored only on your device and are never uploaded to any server; the developer cannot access them. You can optionally turn on "iCloud Sync," which keeps your data in your own iCloud (still not a developer server — the developer cannot read it). See the Privacy Policy.

Does scanning require an internet connection?

No. Text recognition (OCR) and field parsing run entirely on-device — it works in airplane mode.

Which card languages are supported?

Offline recognition currently supports Traditional Chinese, English, and Japanese business cards.

What if a field is recognized incorrectly?

You can review and edit every field before saving, and edit any saved card later.

How do I save a card to my iPhone Contacts?

Open the card's detail page and choose "Add to iPhone Contacts." You can also export all cards as vCard / CSV from Settings.

Will I lose my data when I switch phones?

Card data is stored on-device by default. You can turn on "iCloud Sync" in Settings to keep your cards in sync across your devices; if you leave sync off, export a backup (vCard / CSV) before switching or reinstalling.

The scanner camera won't open or the screen is black?

Please make sure camera access is allowed for the app in system Settings. The document scanner requires a physical device; on the Simulator, use "Import from Photos" instead.
