Grey Kaffee

The Grey Coffee loyalty card – no paper card to get lost in your wallet.

HOW IT WORKS

• Register once, that's it.

• When you pay, the team at the counter will scan your phone with the Grey stamp – one coffee, one stamp. Just make sure the app is open.

• When your card is full, a free coffee will be in your wallet. To redeem it: tap "Redeem" on the voucher, stamp it, and you're done.

WHAT ELSE THE APP CAN DO

• Valid at all Grey Coffee locations: collect here, redeem there.

• Works offline – the app syncs as soon as you're back online.

• New phone? Log in with your email and password, and your stamps and vouchers will be available again.

• Coffee for home: access the Grey online shop directly from the app.

YOUR DATA

• Advertising and reminders only if you explicitly consent – ​​you can deactivate them at any time.

• You delete your account yourself, directly in the app.

• No tracking, no advertising networks.

For NFC, your phone needs an NFC reader – almost all current Android phones and iPhones have one.
