DasBook Privacy Policy

Last updated: March 29, 2026

DasBook is a desktop writing application created by Scott Singleton. This privacy policy explains what data the application handles and how.

Summary

DasBook stores all your data locally on your device. We do not operate servers that collect, store, or process your personal information or creative content.

Data Stored Locally

The following data is stored in a SQLite database on your device:

  • Your creative content: universes, binder nodes (books, chapters, scenes, characters, timelines, research, documents), codex entries, corkboards, snapshots, and publication artifacts.
  • Application settings: AI provider configuration, editor preferences, model pricing, and UI state.
  • AI conversation history: chat messages exchanged with AI providers, including token usage counts, for your reference and for enforcing free-tier usage limits.
  • API keys: keys you provide for third-party AI services (Anthropic, OpenAI-compatible providers) are stored in your local settings database.

You can delete all data at any time by uninstalling the application or deleting the database file.

Data Sent to Third Parties

DasBook connects to external services only when you explicitly use features that require them:

AI Providers (when you use AI chat or generation features)

When you send a message to an AI provider, the following may be transmitted to that provider:

  • Your chat message
  • Recent conversation history (up to 12 messages)
  • Contextual excerpts from your universe content (scenes, codex entries, character sheets) to give the AI relevant context

Which provider receives your data depends on your configuration:

  • Anthropic (Claude): Data sent to api.anthropic.com. Subject to Anthropic's Privacy Policy.
  • OpenAI-compatible providers: Data sent to the base URL you configure. Subject to that provider's privacy policy.
  • Ollama (local): Data stays on your device. Nothing is transmitted over the network.

Time Synchronization (free tier only)

For free-tier users, DasBook makes a single HTTP request on startup to determine the current UTC time for usage quota tracking. This request is made to one of:

  • worldtimeapi.org
  • timeapi.io

Only your IP address is visible to these services (standard for any HTTP request). No personal data, content, or identifiers are sent. Paid-tier users skip this check entirely.

Embedding Service (when you use Deep Search)

If you configure Voyage AI embeddings for semantic search, document excerpts are sent to the Voyage AI API for vectorization. Subject to Voyage AI's Privacy Policy.

Data We Do NOT Collect

  • We do not operate analytics, telemetry, or crash reporting services.
  • We do not collect usage statistics, behavioral data, or device fingerprints.
  • We do not have access to your creative content, API keys, or conversation history.
  • We do not serve advertisements.

Microsoft Store

If you install DasBook through the Microsoft Store, Microsoft may collect data related to installation, updates, and licensing as described in Microsoft's Privacy Statement.

Children's Privacy

DasBook does not knowingly collect personal information from children. The application is designed to be used by writers of all ages, and all data remains on the user's local device.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be included in application updates distributed through the Microsoft Store.
