## What is Business Card Scanner Kardhaus?

Three months later, all you have is "the machinery guy from Nangang". The card is still there; the person isn't.
Kardhaus is for the version of you three months from now.

No account. Photo, crop and text recognition happen on your iPhone and work offline.

■ New: the follow-up, in their language
Tap Write a Follow-up on a card and Apple's Private Cloud Compute drafts the message in their language, with yours beside it so you know what you're sending. Kardhaus first shows exactly what goes: name, title, company, where and when you met, your impression, tags. Never phone numbers, emails, addresses or the card photo. Used for that request only, never stored, not accessible even to Apple. Nothing is sent to Kardhaus. Drafts are saved with the card.
On iOS 27 with Apple Intelligence; otherwise a template writes it. You can turn Private Cloud Compute off in Settings › Apple Intelligence.

■ You forget the name. You remember the room.
The card map puts everyone back where you met them. Or just type "the machine-tool person I met in Taichung last month" and it works out the filters itself, on the device.

■ An impression only you can see
"She handles purchasing, quote due September." Never printed on a card, and three months later the only thing that saves you. Hold the mic and say it — transcribed on the device, the audio never stored.

■ One photo, every field
Cropped, straightened, compressed, then the words go into the right fields: Chinese and Latin names, title, department, company, branch, phone, email, address, even the credentials on a doctor's or lawyer's card. Offline, on a plane or in a basement hall, AI recognition uses the on-device model.

■ The fields a card actually carries
A LINE ID gets its own field with an Add Friend button. So do a tax number, an extension, a licence number and a Japanese card's name reading — not dumped into notes you can search but cannot tap.

■ No need to unlock
On iPhone 16 or later, set Camera Control to Kardhaus and one press shoots a card on a locked iPhone. Also from the Lock Screen, Control Center or the Action Button.

■ Both sides, one contact
Scan the front and back of a bilingual card in one go: one card, fields from both sides. Only shot the front? Tap Add Back; your edits stay put.

■ Your data, your photo library
Export vCard or CSV any time. Import vCard, CSV or card photos, checking the column mapping first. Card photos stay in Kardhaus's own database, never your camera roll, and Kardhaus cannot read your library.

■ iCloud sync, and iPad
Cards live in your own private iCloud database and follow you to a new phone. Native on iPad too, with Split View and Stage Manager.

■ What people ask before installing
Where do my cards go?
Onto this phone, and into your own private iCloud database if iCloud is on. No account, no ads, no tracking, and nothing is sent to Kardhaus: we cannot see your cards. Addresses are looked up in Apple Maps. On iOS 27, AI recognition sends that card's photo to Private Cloud Compute on the same terms as drafts, else Apple Intelligence on the device. Natural-language search stays on the device. With the switch in Settings › Privacy on (the default for new installs), purchase records and a random anonymous ID go to RevenueCat.

## Frequently asked questions about Business Card Scanner Kardhaus

### Where do my business cards go in Kardhaus?

Your scanned cards are stored locally on your iPhone and optionally synced to your private iCloud database if iCloud is enabled. The app emphasizes that no account is required, there are no ads, and no tracking is involved, with your card data never being sent to or accessible by Kardhaus.

### Does Kardhaus have ads?

No, Kardhaus is ad-free. The app's description explicitly states 'no ads' and highlights its commitment to user privacy by not tracking or sending your data.

### How does Kardhaus handle follow-up messages?

Kardhaus can draft follow-up messages in the contact's language using Apple's Private Cloud Compute (on iOS 27 and later). It shows you exactly what will be sent, including name, title, and company, before you send it. This feature is used only for drafting the message and is not stored.

### Can I use Kardhaus offline?

Yes, Kardhaus is designed to work offline. Photo capture, cropping, and text recognition all happen on your iPhone without an internet connection, making it usable even when you're on a plane or in areas with poor connectivity.

### What data can be exported from Kardhaus?

You can export your contact data from Kardhaus in vCard or CSV formats at any time. The app also supports importing these formats, as well as card photos, with a column mapping check.

### How does Kardhaus ensure data privacy?

Kardhaus prioritizes privacy by performing all recognition and processing on your device, requiring no account, and not sending your data to their servers. Follow-up message drafting also uses Private Cloud Compute, with data used only for the draft and not stored.

### What devices is Kardhaus available on?

Kardhaus is available on iPhone and iPad. It offers native support for iPad, including features like Split View and Stage Manager.

### How frequently is Kardhaus updated?

The latest version of Kardhaus is 1.3.1, which was last updated on October 20, 2026. This indicates a recent update, suggesting ongoing development and support.

## Version history (last 5 releases)

### 1.3.1 — 2026-10-20

• AI recognition now works from your very first card, so names, titles and departments land in the right fields from the start.
• Voice notes now listen in your own language.
• Fewer interruptions: Kardhaus asks for your attention less often and no longer brings back screens you’ve already closed.
• On iPad, the empty right-hand side now explains what it’s for and can bring the card list back when it’s hidden.
• Stability and reliability fixes.

### 1.2 — 2026-09-23

• New: "Write a Follow-up". Tap it on a card's page, or long-press any card in the list, and Kardhaus drafts a message in their language, with a version in yours that's just for you. On iOS 27 with Apple Intelligence, Private Cloud Compute writes it; otherwise Apple Intelligence on your device or a template does. Before you generate, you see exactly what goes out: never phone numbers, emails, addresses or the card photo, and nothing is sent to Kardhaus. The draft stays on the card page, ready to copy, and every follow-up you send is kept with the card. Each AI-written draft uses one free AI credit; Pro is unlimited, and templates are always free.
• Kardhaus now runs natively on iPad, in windows of any size, including Split View and Stage Manager. In a wide window, the list and the open card sit side by side.
• The card page's "Add on LINE" button now follows the card, opening whichever messenger is printed on it: LINE, WhatsApp, Telegram or Zalo. If the card doesn't show one, Kardhaus picks what people use where the card is from, such as WhatsApp for an international mobile number or LinkedIn otherwise.
• Fixed: a WhatsApp number printed on a card now opens the chat. Numbers with spaces used to be skipped. LINE official accounts (@id) open correctly too.
• New in Settings › Privacy: "Send purchase records to RevenueCat". When it's on, purchases and restores also go through RevenueCat, which receives the purchase and a random anonymous ID. It never receives your cards or this device's identifier. Pro is still unlocked by your App Store purchase, even offline. It's on for new installs and off if you already used Kardhaus before this update.
• Text that still appeared in English in other languages, such as the camera countdown, batch review and payment screens, is now translated.

### 1.1.1 — 2026-09-18

• The camera opens noticeably faster when you tap Scan a card, getting to the first frame in about half the time.
• A new app icon for iOS 26 and iOS 27: the same fan of cards, rebuilt in Liquid Glass as layered glass cards with real depth. It also looks right when you set your Home Screen icons to dark or tinted.
• iOS 27: a new Private Cloud Compute switch in Kardhaus under Settings › Apple Intelligence. It's on by default; turn it off and AI recognition stays on this iPhone, with no card photos sent to Private Cloud Compute.
• Kardhaus links from kardhaus.com or an App Store event now open straight in the app when it's installed.
• The privacy explanation in Settings has been corrected and now says exactly when AI recognition runs.

### 1.1 — 2026-09-17

• Add the back of a card you've already saved. Tap Add Back below the photo on the card page, then shoot it or pick it from your photo library. Newly read details only fill empty fields; nothing you've edited gets overwritten.
• New Branch field. A line like "Hongda Industrial Co., Ltd. Taichung Branch" is split into company and branch automatically.
• iOS 27: with Apple Intelligence on, AI recognition goes to Apple's Private Cloud Compute and looks at the card photo as well, so decorative typefaces and unusual layouts get read too. The photo is used for that one request only, never stored, and not accessible even to Apple.
• Scan without unlocking: choose Kardhaus in Settings › Camera › Camera Control, then press Camera Control while your iPhone is locked to shoot a card. It also works from the Lock Screen, Control Center and the Action Button.
• Settings are reorganized with what you use most at the top, plus a new Scan cards faster guide that walks you through Camera Control, the Action Button and widgets, step by step.
• vCard export no longer glues company and department into one field.

### 1.0.1 — 2026-08-30

• Vertical cards scan now. Portrait or landscape, the four edges are found the same way.
• A QR code printed on the card always reaches the fields. It used to be missed entirely on some cards — especially faintly printed ones, where the code was readable but the text was not.
• Adding another card of your own can start from the camera or your photo library, instead of a blank form.
• The camera's bottom controls are easier to hit, and Done no longer gets pushed off-screen while you are shooting a batch.
• Auto-shutter reads hand shake more reliably, so it is less likely to fire mid-wobble.
