How we handle your data

Everything you write is encrypted

All creative content — manuscripts, character profiles, locations, lore entries, brainstorming messages, and project descriptions — is encrypted at rest using AES-256-GCM before it touches the database.

This is not optional and not a premium feature. Every piece of creative content is encrypted for every user on every tier.

What we send to AI

When you use an AI feature, we send only the context needed for that specific action. For example:

• Brainstorming: your recent messages and project context
• Prose generation: the current chapter, nearby chapter summaries, and relevant Story Bible entities
• Lore Engine: the entity being discussed and related entities

Content is decrypted in memory for the duration of the AI call, then the plaintext is discarded.

Our AI provider

AI requests are routed through OpenRouter. OpenRouter's default policy is no training on user content. They disassociate inputs and outputs from your user ID and do not store prompt or completion text beyond what's needed to fulfill the request.

AuthorBuilder does not opt into any training data programs with any provider.

Your work is never used to train models

Your creative content is never used to train AI models — not by AuthorBuilder, and not by our AI providers. This is not a marketing claim. It is how our infrastructure is configured.

Pen name first

No real name is required anywhere in the app. Your email address is used solely for authentication (magic link sign-in). Your pen name is your identity inside AuthorBuilder.

Your data is portable

You can export all your prose and Story Bible data in JSON and plain text formats at any time. Your work is yours — you can leave whenever you want.

Account deletion

You can request complete removal of all your data — encrypted content, embeddings, behavioral signals, and account information. Email [email protected] and we'll process it promptly.

Third-party services
