About this app
Cardnook is a loyalty-card wallet that puts all your store cards on your
phone — and respects your privacy while it's there.
Scan a card once, then show its barcode to the cashier in full-screen.
No more rummaging through plastic.
WHAT MAKES CARDNOOK DIFFERENT
• Local-first. Your card data lives on your device. Backup is optional
and stays inside your account — we don't sell your data, and the only
third-party touch on opt-in cloud backup is Supabase, our data
processor (server-side storage), under EU GDPR rules.
• Offline-first. The app reads and writes only on your phone — the
network is never on the hot path. Show a barcode at the till even with
no signal.
• Brand logos when you want them. Tap "Fetch logos" and Cardnook looks
up brand favicons for recognised store names — common retailers are
matched in seconds. The lookup is always user-initiated; never
background, never automatic.
• Around here. Optional location-based suggestions: turn it on and Cardnook
learns where you use each card, then offers the right one when you
return. Locations stay on your device — they're never sent to the cloud.
CORE FEATURES
• Fast scanner — supports EAN-13, UPC-A, Code 128, Code 39, QR codes,
PDF417, Aztec, Data Matrix and more.
• Bright, full-screen barcode display with auto-brightness and screen
wake-lock so the cashier can scan it cleanly.
• Pinch to zoom on the barcode if a reader needs more or less detail.
• Search and sort your wallet by recency, name, or most-used.
• Customisable per-card colour and store-detected name.
• Soft delete with undo — accidental swipes don't lose a card.
• Up to 64 cards per wallet (more than anyone needs in practice).
CLOUD BACKUP — OPTIONAL, PRIVATE
If you turn on cloud backup, your cards are mirrored to a private encrypted
backend so they survive a reinstall or a new phone. Account linking with
Google, Apple, or an email address lets you restore on another device.
What is backed up: only the card information you entered.
What is NEVER backed up: locations, camera images, anything else.
CARDNOOK NEVER
• Sells your data — for any purpose, to anyone.
• Asks for permissions it doesn't need.
• Records anything from your camera. The scanner reads barcodes in-place
and the frames are discarded immediately.

Updated on
Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
What’s new
Cloud backup is more reliable. If a backup stalls on a bad connection it now
times out and tells you what happened instead of waiting forever.
Settings now sits clear of the on-screen navigation bar, so every option at
the bottom of the list is reachable.
Smoother ads behind the scenes: no prompts that cannot work while you are
offline, a more responsive close button, and no doubled-up ads when the
connection is slow.
