Privacy Policy

Effective Date: November 12, 2026 · Operated by Ascua Labs LLC

Ascua Labs LLC (“Ascua,” “we,” “us,” or “our”) builds Ascua™, an AI-native book reading application for Web, iPhone, and iPad. Reading is an intimate intellectual activity. This Privacy Policy explains clearly what information we collect, how we use it to provide Ascua, and the strict boundaries we maintain around your personal library.

1. Information We Collect

• Account & Early Access Contact Information: When you request Early Access, create an account, or contact support, we collect your email address and any message details you voluntarily provide.
• Personal Library Content: When you import DRM-free ebooks (such as EPUB, MOBI, or AZW3 files), bookmarks, highlights, reading positions, or personal notes, we store and process those files solely to render, synchronize, and export your personal library at your direction.
• AI Co-Reading & Book Design Context: When you use Read together or Book Design, Ascua transmits the relevant book passage, structural metadata, and your question to our configured AI inference providers strictly to generate your requested answer, citation links, or typographic stylesheet.
• Billing Metadata (At Commercial Launch): Subscriptions purchased via Apple In-App Purchase or Stripe are processed directly by Apple Inc. or Stripe, Inc. We do not store full payment card numbers on our servers.
• Minimal Technical Logs & Local Preferences: Our website stores your chosen visual theme (Monokai Dark or Paper Light) locally in your browser’s localStorage without third-party advertising trackers. Basic server diagnostic logs (such as error timestamps and request status) are retained briefly to maintain service reliability and security.

2. How We Use Your Information

We use the information above exclusively to:

• Provide, maintain, and improve book rendering, library synchronization, passage-cited AI co-reading, and verbatim-verified Book Design exports;
• Respond to Early Access requests, customer support inquiries, and account notifications;
• Process subscription entitlements and prevent abuse or unauthorized access; and
• Comply with applicable legal, tax, and regulatory obligations.

3. Strict Commitment Regarding Your Reading Data

• No Sale of Personal Data: We never sell, rent, or broker your personal information, reading history, book list, or notes to advertisers or data brokers.
• No Foundation Model Training on Private Libraries: Your uploaded personal books, private reading notes, and co-reading conversations are never used by Ascua Labs LLC to train public foundation AI models.

4. Service Providers & Data Transfers

We rely on reputable infrastructure providers (such as cloud hosting, Cloudflare edge delivery, transactional email, payment processors, and API-level AI inference providers bound by zero-training enterprise/API data terms) solely to operate Ascua on our behalf. Because Ascua Labs LLC is a United States company, data may be processed in the United States and other jurisdictions where our infrastructure operates.

5. Data Retention & Deletion Rights

You retain ownership of the personal notes you write and the legally acquired DRM-free files you import. You may delete individual books, co-reading threads, or your entire workspace at any time, or email [email protected] to request complete deletion or export of your personal data. Subject to applicable law (including GDPR, UK GDPR, and CCPA/CPRA), you have the right to access, correct, export, or erase your personal data.

6. Children’s Privacy

Ascua is not directed to children under the age of 13 (or the minimum digital consent age in your jurisdiction), and we do not knowingly collect personal information from children.

7. Changes to This Policy

If we make material updates to this Privacy Policy as new product capabilities launch, we will update the Effective Date above and provide notice through the application or via email where appropriate.
