Privacy

What we collect, what we don't.

Voixes is built around a simple rule: your PDFs, highlights, notes, and reading history never leave your Mac. This page explains exactly what does leave, and why.

What stays on your Mac

  • Every PDF you open. Stored in ~/Library/Application Support/app.voixes.desktop/papers/.
  • Highlights, sticky notes, and four-color marks.
  • Concept extraction results and flashcard decks.
  • Reading position, view state, and which papers you've opened.
  • Ask-the-paper conversation history.

None of this is sent to a server. Uninstalling Voixes leaves it intact on disk.

What we send to our servers

Account information

Email + password (or hashed token), Pro subscription state. Standard auth data. Stored in our Neon Postgres database; never shared.

AI requests, when you use them

When you use Ask-the-paper, "Explain this figure," concept extraction, or any other AI feature, the selected text + your question are sent to our AI provider (currently AWS Bedrock running Anthropic's Claude). The full PDF is not sent — only the specific passages you're asking about. We don't store the request or the answer on our servers; they're persisted only on your Mac in the local SQLite database.

Anonymous usage events

The app sends a small stream of aggregate events — things like "a paper was opened," "Quick Glance was used," "Ask was sent" — to our own database (not a third party). These help us understand which features matter so we can keep building the right things.

What we don't include:

  • The PDF file or any of its content.
  • The paper title, author, or DOI.
  • The text of your questions or the AI's answers.
  • Your highlights, notes, or annotations.
  • Your email or name. Identity is hashed before storage.

You can turn this off any time: Settings → Privacy → Help improve Voixes. It's on by default. Once disabled, the queue is dropped immediately and nothing further is sent.

What we never collect

  • The contents of any PDF you read.
  • Your browsing history outside Voixes.
  • Microphone, camera, location, or contacts.
  • Anything stored elsewhere on your Mac.

Who has access

Server-side data (account, AI requests in transit, usage events) is accessible only to Voixes maintainers. We do not sell or share it. The AI provider (AWS Bedrock) processes your prompts to generate answers; their data-handling policy is the standard AWS Bedrock one, which does not retain prompts for training.

Changes to this policy

If we change what's collected, we'll update this page and surface a notice in the app the next time you open it. You can always check the current version at voixes.com/privacy.
