Publishify Masthead
The full text of your book and its section summaries stay on your computer and never reach Publishify's servers. The AI on your own Claude account reads the book, under the Anthropic terms that apply to your account.
These reach and are stored on the Masthead server:
- The email address and account id of your Google account (for sign-in and your licence)
- Your book's title, genre, language, section titles, word counts and fingerprints
- Editorial notes, quotes of up to 25 words, counts, and the reports built from them
No AI runs on our servers. We do not use your manuscript to train AI or as test data.
Publishify Studio
Your writing stays on your own device first. If you create an account, your books are kept on our server so they can sync between devices. If you connect Google Drive, your files stay in your own Drive. If you publish a page, that page becomes public.
Service providers
Our servers run on Cloudflare. Google is used for Google sign-in, and Anthropic, through your own account, for Masthead readings. We do not sell your data.
Cookies
The website uses no advertising or tracking cookies. During sign-in, short-lived cookies are used only to keep the sign-in secure.
Deleting your data
Masthead data is kept until you delete the book. You can start a deletion from Masthead and confirm it through a single-use link, or write to us.
