The Tomorrow Footprint feature is an offer we're making - whether you want to accept it is of course up to you. If you don't want to see the COemissions of your purchases, you can simply decline this option and use your app as usual.

You can switch your COfootprint on and off in the settings at any time. Once switched off, your data used until then will be deleted by us and by Ecolytiq, and no further data will be collected for the COfootprint feature. 

Here's how to switch it on and off:
Profile → Manage Account → Activate Footprint → toggle on/off.
