Cookie Policy

I’ve been advised by my lawyer that my cookie policy could basically be “we don’t use cookies.” I don’t track anything and I don’t have social media embeds. But at the same time, I sometimes embed videos into blog posts, and the plugin I’m using can shut off that sort of functionality. I like that, so I’ve included the plugin on my page.

No login or storage of personal data is allowed on this webpage, which is only intended to act as a description of the services provided by Barefoot Data Science.

Cookie Consent: A single cookie will be used to track your acceptance or decline of the cookie policy. This will remain in use for 7 days before expiring, but may be deleted from your computer manually as desired.
