Do you do business in California AND derive 50% or more annual revenue from selling residents’ personal information?
Note that personal information under the CCPA includes most cookies.
The law is broad on what "selling" personal information means and is, but it is broader than a layman's definition. For instance, it could include publishers selling targeted ads. If you're on the fence about whether or not this applies to you, we'd recommend speaking to your attorney about it.
Sale within the context of the CCPA is defined as: selling, renting, releasing, disclosing, disseminating, making available, transferring, or otherwise communicating orally, in writing, or by electronic or other means, a consumer's personal information by the business to another business or a third party for monetary or other valuable consideration. See also Osano’s article on the definition of sale.
