## What The Pillar is

The Pillar is a browser game and advertising marketplace. A window is a licensed ad pane on a 3D 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 collect

When you sign in we receive your public profile from X: your handle or name, avatar, and an account identifier. We store this to show who lit a window and to run the lobby chat.

We store the chat messages you post and the windows you light. We keep basic cookies for your sign-in session.

## Analytics

We use Google Analytics 4 to understand how the site is used (pages viewed, rough location, device). Google Analytics sets its own cookies and processes this data on Google's servers. We also use Cloudflare, which sits in front of the site for security and performance and sets a small analytics beacon.

This is basic usage measurement, not advertising tracking. We do not run ad-network trackers that follow you across other websites, and we do not sell your personal data.

## Processors

The app and its database run on Railway. Payments are handled by Stripe. Sign-in is handled by X. Analytics is handled by Google (Analytics) and Cloudflare. These providers process data on our behalf.

We do not sell your personal data.

## Your choices

You can stop using the app at any time. To request deletion of your account data, email contact@extensionsmarket.com and we will delete it within 30 days.

This page is a plain-language summary of what we collect and why. It is not legal advice.
