StoryMaster Pro is built by Itamar Elliott in Israel. Contact: itamar@storymasterpro.com.
You can use StoryMaster Pro without an account; your work then stays on your device. If you create an account, we store your email address, the date you confirmed your age, and your account approval status.
If you sign in with Google, Google shares your name, email address and profile picture with us. We use them only to create your account and sign you in. We do not receive your Google password or access to anything else in your account.
Books, chats, stories and your writing profile are saved on your device. When you are signed in, they are also synced to your account so they follow you to your other devices. When you delete an item in the app, its synced copy is deleted too.
When you use writing, editing, illustration or voice features, the text needed for the request (and, for live voice, your voice) is sent through our server to AI processing partners to produce a response. Our server does not keep the text of requests; it keeps request counts per account to enforce usage limits.
Account details and synced content are stored with an authentication and database provider. The website and server run with a hosting provider. Settings are kept in your browser or app storage.
We do not sell your data. We do not use advertising or analytics trackers.
You can delete books and chats from the app. To request deletion of your account and associated synced data, email itamar@storymasterpro.com.
