Cookie policy

Every cookie and browser storage key that cf0 uses on cf0.ai and in the app, and how to change your choice.

Your choice

In the EU, Malta and the UK, cf0 asks before it sets any cookie that is not strictly necessary. Reject all and Accept all have the same weight, and no optional category is on before you choose. cf0 keeps your choice with the policy version and the time you chose. When this list changes, the version changes and cf0 asks again.

In the US, you can opt out of the sale or sharing of your personal information: open the settings and turn off Analytics and Marketing. cf0 treats a Global Privacy Control signal as that opt-out.

Cookie settings

The privacy policy tells how cf0 uses the data these cookies carry.

Strictly necessary

The site and the app do not work without these. They are always on.

  • cf0.cookie-consent
