If you join a business's Stamp Card, they may receive access to your basic personal information that you signed up with.
They can use this to send you communications, (such as special offers or extra rewards) through the Stamp Me App, via Push Notifications or SMS messages. They may also use your email address to contact you via email.

Tap the settings icon
Tap 'Communication Preferences'.
