When you link a card through CheckPoints, you can rest assured that we are using anonymized data, and encrypting it end-to-end through our integration with Plaid.
We use the transaction history of your account to provide anonymized market research to our partners, and to provide a better overall ad experience across the CheckPoints app.
To see what accounts you have linked with CheckPoints as well as other apps, create an account here: https://my.plaid.com/.
Once you've setup your account there, you'll need to login to your linked accounts to verify that it's really you. From there, you'll be able to 'Manage Connections', and delete/remove cards as you please.
