Common questions

Do I need an account?

No. Everything works without one, and your data stays on your phone. Sign in from Settings (the gear at the top right) only if you want a backup you can restore on another phone.

How do I go through the setup guide again?

Open Settings (the gear at the top right) and tap Start the setup guide. Will Shark walks you through it again and adds to what you already have.

Does Card Shark connect to my bank?

No. You add your cards by name and mark credits as used yourself. Card Shark never asks for card numbers or bank logins.

A card's credit, date or earn rate is wrong

Open the card and tap Something wrong? Tell us. We check every report against the card's terms and fix it for everyone, without an app update.

My card isn't listed

You can add it as your own card with its annual fee and goals. Email us which card it is and we'll look at adding it with its credits and perks.

I'm not getting reminders

Card Shark's reminders are notifications your phone schedules. Check that notifications are on for Card Shark in your iPhone's Settings under Notifications, and that the reminder you expect is turned on for that card in the app.

How do I delete my account?

Tap the gear at the top right to open Settings, then Delete account. This deletes your account and its backup. The data on your phone stays until you delete the app. See the privacy policy for details.
