CardHaus Help
Getting started
How do I scan my first card?
Open CardHaus, tap the floating glass camera button on the Home tab, and point it at any business card. The scanned card is added to the list.
How do I import a card from a photo I already have?
Tap the + button in the toolbar → “Import from Photos” → pick the image. CardHaus reads it in the background.
Does it work offline?
Yes — every core feature (scanning, search, sharing, saving to iOS Contacts) works without an internet connection. The optional Microsoft 365 / Dynamics 365 export needs a connection at the moment you tap export.
Editing & organising
How do I change a category, add a tag, or write a note?
Tap the card in the list, then tap Edit in the top-right.
How do I make my own custom category?
Settings → Categories → “+ New Category”.
How do I delete a card?
Swipe left on the card and tap “Delete”. Or open the card and tap the trash icon in the toolbar.
How do I export everything?
Settings → Export → choose CSV or vCard. The file is shared via the standard iOS share sheet.
Microsoft 365 / Dynamics 365
What does “Connect to Microsoft 365” do?
It lets you push a scanned card into your Outlook contacts with one tap. CardHaus uses the standard Microsoft sign-in flow (OAuth 2.0 with PKCE) — your password is typed into Microsoft's own page, never into CardHaus.
Why does my Dynamics 365 sign-in say “Need admin approval”?
Dynamics requires a tenant administrator to approve the app's
user_impersonation permission once per organisation.
Forward the message to your IT admin; once they approve, every user
in your tenant can connect without further prompts. (This is a
Microsoft policy, not a CardHaus limitation.)
How do I sign out / disconnect?
Settings → Connections → tap the connected service → “Disconnect”. This removes the OAuth token from your device's Keychain immediately.
Privacy
Where are my cards stored?
Only on your iPhone or iPad, in the app's encrypted SwiftData container. CardHaus has no server.
Do you sell my data?
No. We can't — we don't have it. See the full Privacy Policy for the complete data inventory.
How do I delete everything?
Settings → “Erase all data” wipes every card and disconnects every integration. Uninstalling the app does the same.
Languages & accessibility
How do I switch to Arabic?
Settings → App Language → العربية. The whole UI re-lays itself right-to-left.
Does it support VoiceOver / Dynamic Type?
Yes — every screen scales up to the largest accessibility text size and every interactive element has a VoiceOver label.
