We store certain information that gets collected automatically at our end through cookies and other similar technologies. A cookie is a small string of information that a website that you visit transfers to your browser for identification purposes. Cookies can be used to follow your activity while using a website or across websites, and that information helps companies understand your preferences and tendencies, as well as improve and personalize your website experience. Some cookies are necessary to operate a website, while others can be functional or analytical. Cookies on the RC Website are generally divided into the following categories: You can also prevent the use of certain cookies by modifying your Internet browser settings, typically under the sections “Help,” “Internet Options,” or “Settings.” If you disable or delete certain cookies in your Internet browser settings, you may still access the RC Website, however, you might not be able to access or use important functions or features of the RC Website.

We also work with third-party analytics companies and advertising networks to understand how our Applications are used and to display advertisements that we believe will be relevant to you. We use AdMob from Google for part of this process. You can opt out of personalized advertisements under the “Settings” section of our Applications.

Do-Not-Track Signals At this time, we do not recognize automated browser signals regarding tracking mechanisms, which include “do-not-track” instructions.

Our primary purpose in collecting your information is to provide the RC Website and Applications to you and to provide services requested by, or reasonably anticipated within the context of our relationship with you. We may also use your personal information for the following purposes:

We may also share personal information with third parties in connection with a change to the control or financial status of the company, including a corporate restructuring, sale, acquisition, financing, reorganization, bankruptcy, receivership, transfer, assignment of assets, or business merger or divestiture.
