The Important Stuff

We will not sell, distribute, or lease your personal information to third parties unless we have your explicit permission or are required by law to do so. We may use your personal information to send you promotional information about third parties which we think you may find interesting if you tell us that you wish this to happen.

We encourage you to review our Privacy Policy whenever you access the Services or otherwise interact with us to stay informed about our information practices and the ways you can help protect your privacy.

For example, if you create or log into your account through a third-party social media site, we will have access to certain information from that site, such as your name, account information, and friends lists, in accordance with the authorization procedures determined by such social media site.

Third-Party Information

We may work with third-party service providers to help improve our Services. When you interact with third-party providers, you may be providing information directly to the third party. Some third-party services we engage include:

• Beehiiv
• Cloudflare

Note that when you use third-party services, their own terms of use and privacy policies will govern your use of their services. If you have any questions about such policies, you should contact the responsible provider directly.

Opting Out of Targeted Advertising, Sharing, and Sales

We process personal information to understand and improve your experience with our Services and to serve you targeted advertisements. Some of these activities may be considered "sales" or "sharing" of your personal information or "targeted advertising" under certain privacy laws. To opt out of preference-based advertising, use this form. Note, this will not stop you from seeing sponsorships or advertisements in our newsletters, but those ads will be selected randomly rather than based on your known preferences.

Security

We, or through third-party service providers, have implemented reasonable measures designed to secure your personal information from accidental loss and unauthorized access, use, alteration, and disclosure. Unfortunately, the transmission of information via the Internet is never completely secure. Although we reasonably try to protect your personal information, we cannot guarantee the security of your personal information transmitted to our Services. Any transmission of personal information is at your own risk.
