Description
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.

Recent changes: 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.
