Features
The details that matter
Copy when you need it. Gone when you don't.
Sensitive fields stay masked until you authenticate. Copies stay on this device and expire after 30, 60 or 120 seconds, and sensitive details hide automatically during detected screen recording or mirroring.
Addresses in Chinese, pinyin and English.
Keep Chinese, pinyin and English versions of a billing address and copy the field each form asks for. Membership barcodes open full screen for scanning.
Only on this iPhone.
Your data lives in an encrypted vault on this device, outside iCloud backups, and the app never connects to the internet. When you change phones, export a backup encrypted with a password you choose.

Questions
Good questions
Does UUCards cost anything?
UUCards is free to download. Every feature and theme is included, there is no card limit, and there are no in-app purchases, subscriptions or ads.
Is my card information uploaded anywhere?
No. UUCards has no networking features and no account. Your data is encrypted on your iPhone only; the developer cannot see it or recover it for you.
How do I move my data to a new phone?
The vault can only be opened on this device, so iCloud backups and device-to-device transfers can't bring it along. Before you switch, export an encrypted backup from Settings → Backup & Restore and import it on your new iPhone. Keep the backup file and its password safe; a forgotten backup password cannot be recovered.
Is UUCards connected to my bank?
No. UUCards is a private, local notebook for your card details. It doesn't process payments or connect to any bank, and bank or card-network names only identify your cards.
Where can I get help?
Email support@uuthings.com with your app version, iPhone model and iOS version. Please never include card numbers, security codes, backup files or backup passwords.
