Short, because there is not much to say.
What we collect
When you sign in with X we receive your X user id and username. When you apply we store the wallet address you type, that id, that username, the time, and the link to the reply you verified. That is the whole list.
Why
The id stops one person applying twice. The wallet is the waitlist. The reply link is the proof you did the task.
What we do not do
We do not post as you, follow anyone, read your timeline or your messages, or keep your X access token after login. We do not sell or share the list with anyone. It exists to build one whitelist for one mint.
How long
Until the mint is over and the list is on chain. Then it is deleted from the database.
