What The Pillar is
The Pillar is a browser game and an advertising marketplace: One Floor Each, a tower people build together one floor each, and a 3D open-world city. A window is a licensed ad pane on its 80-floor tower, not real property and not a security.
This page is a plain-language summary for players and advertisers. It is not legal advice, and a window on The Pillar is not real estate and not an investment.
What we use
The Pillar sets a session cookie so you stay signed in after logging in with X. Without it you would have to sign in on every page.
We use Google Analytics 4, which sets its own cookies to measure how the site is used (pages viewed, rough location, device). Cloudflare, which protects and speeds up the site, sets a small analytics cookie or beacon as well.
When you pick the tower on the front page, a small cookie remembers that choice for six hours, so thepillar.io takes you straight to the tower until then. It holds nothing else.
These are for our own understanding of usage and site security. We do not run advertising trackers that follow you across other websites, and we do not sell your data.
