When you start creating your Privacy Policy, the first set of questions will be used to determine what privacy laws apply to you, and thus what disclosures your Privacy Policy needs to contain. The question of "do you derive 25% or more of your gross revenue from selling the personal information of residents of Oregon" is one of the questions that will determine whether you need to comply with the Oregon Consumer Privacy Act (OCPA).
In this case, "gross revenue" refers to the income generated from normal business operations such as sales of goods or services. Gross revenue is income prior to expenses such as salaries, rent, or software costs.
The Oregon Consumer Privacy Act has a very broad definition of "sale", meaning that you may be selling personal information without even realizing it. The law defines "sale" as exchanging personal data for monetary or other valuable consideration. This means that "sale" may include the selling of an email list to a data broker in exchange for money. "Sale" may also include exchanging personal information (e.g. IP addresses) with an analytics provider in exchange for better analytics.
If you are selling the personal information of residents of Oregon and such sales account for 25% or more of your gross revenue, then you should answer "yes" to this question.
