What is stored, why, and how to have it deleted.
Last updated 21 September 2026
Your email address and a hash of your password. The password itself is never stored.
Your purchases, as reported by WarriorPlus: which offer, the order id, and whether it is active or refunded.
The books you make: their settings, the text you paste in, the pictures you upload and the PDF files the studio builds from them.
Ordinary server logs, and a log of emails the studio sends you.
No card numbers or payment details. The payment happens on WarriorPlus, which is where those details stay.
No advertising trackers, no analytics scripts, no third-party pixels. The only cookie is the session cookie that keeps you signed in.
Your ChatGPT account details, which the studio never asks for and never sees.
WarriorPlus, because it takes the payment and tells the studio to open your account.
The server that hosts the studio.
Nobody else. Your books are not read, published, resold or used to train anything.
Your books stay in your account so you can come back to them. Email thuthao07082002@gmail.com to have your account and everything in it deleted, and it is done.
Deleting your account does not take back the files you have already downloaded - those are yours.
