## 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 you are buying

Lighting a window is a monthly advertising licence. You pay a fixed monthly price for that pane, charged through Stripe. The price you see on the pane is the price you are charged, to the cent.

The licence renews automatically each month at the same price until you cancel. We only change a price for future renewals, and only after telling you in advance.

## How to cancel

You can cancel any time by releasing the window from the tower while signed in, or by emailing contact@extensionsmarket.com. Cancelling stops future renewals.

When you cancel, your brand stays on the pane until the end of the month you already paid for, then the pane returns to inventory. We do not pro-rate or refund the current month unless the law requires it.

## Errors and disputes

If you are charged in error, email contact@extensionsmarket.com and we will respond within 5 business days.

During preview, some windows may be free; free windows involve no charge and no refund.
