Introducing QuanCard

A little joy, every time you open it.

Browse, arrange, and give each card a place. Just as you would with the things you love collecting.

App screenshots · fictional details for demonstration

Card artwork and trademarks belong to their owners. Display implies no partnership or endorsement. Details are fictional and cannot be used for payment.

A collection you can feel.

Browse a stack or switch to a grid. Press and drag to arrange cards, then filter by region or favorites.

Accounts belong here, too.

Keep bank accounts separate from cards, with routing details, currencies, and notes together.

Keep the design you love.

Add your own card photos or choose a simple template. Make the collection feel like yours.

全卡卡Made for the collector in you.

A place for your cards. And your peace of mind.

What you treasure deserves care. Your information starts on your own device.

Read our privacy note

Local first

No QuanCard account needed for your local collection. Browse and organize offline.

Encrypted on your device

Card details, account information, and photos are encrypted before they are stored.

Reveal with intention

Only the last digits appear by default. Authorize to reveal details. The app covers your vault in the background; a brief return keeps details masked, and a longer absence requires unlocking.

A backup you control

Export cards, accounts, artwork, and order in a password-protected backup. Preview conflicts before choosing how to restore.

Keep it local. Or sync your way.

Local, iCloud, or your own server. You choose where your collection lives.

Local

The default

Encrypted on your iPhone. No account or connection needed. Keep your collection with you, offline.

iCloud

With your Apple account

Sync between your own iPhones. Cards, accounts, and artwork are encrypted on your device before reaching your private iCloud space.

  • Encrypted sync

Your server. Your rules.

Run QuanCard’s sync service on your own server, manage your cards in the browser, and pair your iPhone with a single scan. Your data stays encrypted, and you stay in control.

Self-hosted, your call
Your server, your domain. You decide where the data lives, when to back up, and when to upgrade.
Manage cards on the web
Browse, add, and organize cards and accounts in a desktop browser. Scan once with your iPhone and both stay in sync.
Secure, and in your control
Cards are encrypted on your device before they sync. The server keeps only data it cannot read.

Server open source under AGPL-3.0The QuanCard app is commercialzoolapp / quancard-server

Sync is opt-in. Local mode uploads nothing. Choose one sync backend at a time; disconnect before switching, keeping your local collection.

The self-hosted project is a development preview. You manage deployment and maintenance.

A few things to know

Can I download it now?

Join the public TestFlight beta and install it on an iPhone running iOS 26 or later. Verify your email on this website to open TestFlight immediately; no manual approval is needed. The App Store release is not available yet; you can also join the launch waitlist for a reservation number and an email when it launches.

How much will it cost?

Join the app waitlist for early-bird pricing at launch. Prices and the release date will be announced later.

Can I pay or apply for a card?

No. QuanCard organizes cards and accounts you already own. It does not issue cards, connect to banks, handle funds, or help bypass KYC or regional restrictions.

Which devices and languages are supported?

The first release is designed for iPhone running iOS 26 or later. The app has Simplified Chinese, Traditional Chinese, English, and Japanese. The native app starts on iPhone; the self-hosted service also includes a web vault.

Do I need an account or cloud sync?

No. Local mode needs no account or connection. Choose iCloud, or connect your own QuanCard Server. The server and web vault are open source on GitHub and can be modified and extended under their license. Connect in the app to enable sync, using one backend at a time.

Does this website store my card details?

No. This is a product website. It has no card-entry form, file upload, or vault decryption. Never send card numbers, CVCs, account numbers, or backup passwords to this website or the support address.
