These laws have certain threshold requirements which a company must meet in order to be required to comply with its provisions. Upon information and belief, our company does not meet any of those thresholds. In the event of a change in our status, and if the data that you provide in the course of your use of our site, content, products and/or services is governed by CPRA, we will abide by the relevant portions of the Act.

If you are a California resident, you have the right to:

We also comply with California’s “Shine the Light” law (Cal. Civ. Code § 1798.83), which permits California residents to request information about our disclosure of Personal Data to third parties for direct marketing purposes once per year, and California Business and Professions Code § 22581, which allows California residents under 18 who are registered users to request removal of content they have publicly posted.
