On March 6, 2020 Jerome Paulos tweeted a screenshot to @themarkup informing us that our website had a cookie on it. This is bad because we've tried hard avoid using any tracking, and as of today themarkup.org does not serve any cookies.
As my colleague Simon Fondrie-Teitler responded:
Oh, thanks for catching this! I'm guessing those are Stripe-related cookies. If you go to the donate page, enter a number, and click "donate" the stripe javascript does load a couple cookies. See https://themarkup.org/donations/ for more info.
