Privacy Policy

What we collect

Account data: your email address and authentication details.

Book content: the outlines, chapters, codex, characters, formatting and settings you create, and the artwork and audio you generate or upload.

Usage data: a record of AI requests and credits consumed, used for metering and billing.

Technical data: your IP address and basic request details, which our hosting providers process to deliver the service, and error reports when something in the app fails.

Payment data: handled by Paddle. We do not see or store your full card details — we receive only the subscription status and limited billing metadata.

How we use it

To provide and sync the service, run the AI features you use, meter credit usage, manage subscriptions, fix errors, and keep accounts secure. We do not sell your data, and we do not use your content to train AI models.

Service providers (subprocessors)

Supabase — authentication, the database that holds your books, and file storage for your artwork and audio.

Hetzner Online GmbH — the server in Helsinki, Finland that runs our application and background jobs, and keeps nightly backups of the database.

Cloudflare — website hosting, DNS and network protection. It processes your IP address and basic request details when you visit.

OpenRouter and the AI model providers it routes to (for example Google, DeepSeek and OpenAI) — when you use an AI feature, the parts of your book that feature needs are sent to produce the result. That covers outlines, drafting and enhancement, the writing assistant, images (cover art, page art and character portraits) and narration.

Paddle — payment processing, invoicing and sales tax, as Merchant of Record.

Resend — sends account emails such as sign-up confirmation and password resets. It receives your email address and the message.

Sentry — error monitoring. When something in the app fails, a report of the error and the page it happened on is sent to Sentry, stored in the EU.

Google Fonts — the typefaces used in the app and on our website are loaded from Google, which receives your IP address when your browser requests them.

AI processing note

Using an AI feature sends the relevant parts of your book to an AI provider: your brief, outline, codex and chapter text, a page’s artwork direction, or the passage being narrated. Generated images and audio are stored in your account. Avoid putting sensitive personal information into a book you process with AI.

Retention and your choices

You can archive or delete any book from your shelf; deleting removes its content from your account. You may request deletion of your account and associated data at any time. We retain limited billing records as required for tax and accounting.

To exercise any of these rights, contact support@manuscriptstudiopro.com.

Cookies and local storage

We use only what the app needs: your authentication session, basic preferences (such as theme and library view), and short-lived links to your own images so they load faster. We do not use advertising trackers.
