Your address is needed for activating the OK app, debit permissions, and as delivery address. You can add multiple addresses here, allowing you to choose where to deliver an order.
You can fill in or change your address in your settings. From the overview screen, click on the gear icon in the upper right corner. Here you will see your addresses under the header 'Addresses' (if you already have an address). Click 'Add Address' to add an address and an existing address to change it. Then click 'Save' in the upper right corner.
In case you want to delete an address, click on the address. At the bottom, you will see a big red button with the text ‘Delete this address’ to remove the address.
