2. Data Collected & Purposes

We believe in minimal, purposeful data collection:

• Reader Account Data: If you choose to sign in, we process your email address, display name, and authentication token via Firebase Authentication to synchronize your reading progress and saved shelf.
• Reading Progress & Shelf State: Chapter bookmarks, reading duration, and saved monograph references, stored in your browser's IndexedDB and securely synchronized via Cloud Firestore.
• Technical & Security Telemetry: Standard server logs (IP address, user agent, requested URLs) processed on our European cloud infrastructure (europe-west1) for routing, security, and rate-limiting.
• Optional Analytics: If and only if you accept analytics cookies via our banner, minimal usage telemetry is processed to measure catalogue popularity.

3. Legal Bases (GDPR Art. 6)

We process personal data under the following GDPR legal bases:

• Contractual Performance (Art. 6(1)(b)): To deliver the digital reading experience, catalogue browsing, and cloud library synchronization requested by you.
• Legitimate Interests (Art. 6(1)(f)): To maintain platform security, prevent abuse, and optimize publication performance.
• Explicit Consent (Art. 6(1)(a)): For optional first-party analytics cookies.

Knowelia runs on enterprise cloud infrastructure provided by Google Cloud Platform / Firebase (europe-west1). Data is encrypted in transit (TLS) and at rest.
