Cardugo vs Nestkeep

ZERO DATA COLLECTION, BY DESIGN Most card wallet apps include analytics SDKs, phone home on launch, or sync to a cloud you never agreed to. Cardugo contains no networking code of any kind - not disabled, just absent. Your data cannot leave your device. • Zero outbound network connections - ever • No analytics, no crash reporting, no tracking SDKs • No permissions requested - only Face ID, and only if you enable it • No account required - no email, no sign-up, no server • No cloud sync - you own your data, period REAL ENCRYPTION. NO BACKDOORS. Every sensitive field - card number, CVV, PIN, notes - is encrypted with AES-256-GCM before being written to storage. The encryption key is derived from your 6-digit PIN using PBKDF2-SHA256 with 200,000 iterations. Turn on Face ID for instant unlock - a copy of the key is sealed in the iOS Keychain and never leaves your device. Forget your PIN and there is no reset path, no recovery email, and no backdoor. That is the point. STUNNING CARD VISUALS Every card is rendered at the exact ISO 7816 credit-card dimensions. Choose from 115 real bank card themes or build your own with 3 layouts, 4 font styles, 12 background patterns, 10 gradient presets, and multiple chip and stripe styles. Fluid card flips, a stacked deck that fans open, and natural drag-to-reorder keep everything moving at a smooth pace. INTELLIGENT INPUT Cardugo suggests the issuing bank and card name from ~2,900 IIN mappings and auto-detects the payment network as you type. Real-time Luhn checksum validation catches typos before you save. BACKUP AND RESTORE Export an encrypted .cardugo backup file protected by a password of your choice - independent of your app PIN. Import merges into your existing collection without overwriting anything. WHAT YOU CAN STORE • Credit, debit, and prepaid cards • Bank accounts with routing and account numbers • Free-form encrypted notes up to 500 characters per card • Unlimited cards with drag-to-reorder 8 languages: English, Spanish, French, German, Chinese, Japanese, Portuguese, Korean.

Nestkeep is the simple memory for your home. It does two things, and does them well: it reminds you about the things a home needs before they slip your mind, and it keeps your receipts, warranties and manuals in one safe place. No setup, no accounts, no clutter. Add something only when you want to. REMINDERS - Add anything a home needs on a repeat: water filter changes, smoke alarm batteries, gutter cleaning, insurance renewals, servicing. - Choose how often in days, weeks, months or years. It starts today and repeats until you delete it. - See at a glance what is due, due soon, or overdue. - Swipe to mark done or snooze a week. When you complete one, the next is scheduled automatically. - A gentle reminder arrives at 9am on the day something is due. STORAGE - Keep receipts, warranties, product labels and manuals so you never lose them. - Add a name, a note and up to 10 photos per item, straight from your camera or library. - Search by title or notes to find anything in seconds. - Export a photo back to your Photos whenever you need it. PRIVATE BY DESIGN - No sign up, no account, no ads. - Everything stays on your phone and is included in your normal iCloud device backup. - We do not collect your data. There is no server. Nestkeep keeps your household running: don't forget anything, don't lose anything.
