What we count

We use PostHog, an analytics service, to count visits: which pages get opened, where visitors came from, and how far they get on the crowdfunding page. It keeps a random ID in your browser so a second visit isn’t counted as a new person. It doesn’t record what you type or what’s on your screen. If your browser sends Do Not Track, we don’t count you at all.
