Everything you enter stays on your iPhone. There’s no account, no tracking and no advertising, and we never ask for card numbers or bank logins. See the privacy policy.

Go to Settings › Back up now and save the backup file (for example to iCloud Drive). On the new iPhone, install Cardinko, go to Settings › Restore from a backup and pick that file.

Every card’s rates, caps and minimum spend are checked against the bank’s latest official terms and conditions. Each card’s Rules & terms page shows when it was checked and links to the bank’s documents.

Please tap Report a wrong rate on that card’s page. It opens an email with the details we need; a screenshot of your statement or the bank’s page helps. We re-check the bank’s official terms before changing anything.

Email us the card’s full name and we’ll add it after checking the bank’s terms.

Banks decide bonuses by the category code the merchant’s bank uses, which isn’t always what you’d expect (for example, some restaurants are coded as fast food). Caps, minimum spend and exclusions also apply. Cardinko’s figures are estimates; your bank’s statement is the final word.

Go to Settings › Payment reminders in Cardinko. If you don’t get reminders, also check that notifications are allowed for Cardinko in your iPhone’s Settings › Notifications.

Go to Settings › Delete all data, or delete the app. Both remove everything Cardinko stored on your iPhone.
