Privacy

Last updated October 4, 2026

You are writing a book. That is about as personal as data gets, so here is exactly what happens to it, in plain English.

What we store

• Your account: the email address you sign up with (and, if you use Google sign-in, your name as Google provides it).
• Your work: manuscripts, Story bibles, comments, imports, and your voice fingerprint. Stored in our database, scoped to your account, protected by row-level security.
• Your voice fingerprint: how you write, never what happens in your story. It keeps a reading of your style and the rules drawn from it, rewritten to leave out your characters, places and plot before either guides a draft; any rule you write yourself, as you wrote it; passages from the sample you gave it, to write beside, used only in a book whose own pages hold them, so a sample from another story never reaches that book’s drafts; the names and story words of that sample, kept only so they stay out of what it writes for you; how often you use each pattern the margin watches for, kept as numbers, and your often-said phrases as one-way hashes, never as words, so a habit of yours is never marked as a machine’s; and, where we rewrote a fingerprint after it was built, the reading it had before, kept only so that rewrite can be undone, and deleted with the book or your account.
• Pictures: any picture you add to an entry in your Story bible. Stored privately in the same place as your work, shown only to you through links that expire, never used to train anything, and erased with your account.
• What you remove: anything you remove from your Story bible is kept for 30 days, pictures included, so you can bring it back. After that it is erased for good. Remove for good erases it at once.
• Settings: things like your pushback dial. Your theme choice stays on your device.

What we never do

• Your writing never trains shared models. Not your manuscript, not your Story bible, not your voice fingerprint. Your voice profile exists to write for you, and no one else, ever.
• We never sell or rent your data. There are no ads.
• We run no third-party analytics or ad trackers. The only cookies are the ones that keep you signed in.

The AI part, honestly

When you ask Verbaire to draft, critique, or check your work, the relevant text is sent to a large-language-model provider (currently Anthropic and OpenAI) to generate that one response, under API terms that do not permit training on your content. That is the entire trip your words take: to the model, back to you.

Where it lives

Your data is stored with Supabase (database and authentication) and the app is served by Vercel. Both act as processors on our behalf.

When you pay

When you buy a plan, Stripe is the merchant of record for the purchase: it receives your name, email address, and payment details to complete the sale, and its handling of that data is governed by Stripe’s own privacy policy at stripe.com/privacy. Your card number goes directly to Stripe; Verbaire never sees or stores it.

Leaving

Settings has a Delete account button. It erases your account and everything attached to it: manuscripts, Story bibles, pictures, voice data, comments, all of it. No exit interview, no retention window games.
