Privacy Policy

1. Data Controller

This Privacy Policy outlines how your information is handled by Roman Fofanov / Lector Page ("we", "us", or "our"), operating the web portal https://lector.page and the mobile application Lector: AI Audiobook & Karaoke Reader (Package Name: app.lectorreader.audiobook).

If you have any questions or requests concerning your privacy, please contact the Data Controller directly:

• Founder & Controller: Roman Fofanov
• Direct Email: roma@lector.page
• Support Desk: support@lector.page
• Official Website: https://lector.page

2. Strict On-Device Privacy Architecture

Lector is architected from the ground up to protect intellectual privacy and reading confidentiality:

• Local Book Processing: When you open or import books formatted as EPUB, FB2, PDF, TXT, or ZIP archives, parsing, metadata extraction, word tokenization, and rendering happen purely in device memory and storage. Your books are never uploaded, copied, or transmitted to any external server or cloud service.
• Neural TTS On-Device Synthesis: Text-to-speech audio generation runs strictly on your device utilizing embedded local neural engines such as Sherpa-ONNX and Piper. Voice generation requires zero active internet connection and does not stream your text to third-party TTS APIs (such as ElevenLabs, Google Cloud TTS, or OpenAI).
• Reading Analytics & Bookmarks: Your reading progress, playback speeds, sleep timers, pitch settings, highlighting, and customized voice profiles are stored exclusively in your device's local application sandbox.

3. Information Handled by Third-Party Services

While the reader engine is strictly offline, certain device-level technical interactions are processed through industry-standard third-party providers when you access optional commercial features:

A. In-App Purchases (Google Play Billing)

If you purchase a PRO Subscription or a Lifetime Pass, transactions are processed directly by Google LLC via the Google Play Billing API. We never see, receive, or store your credit card numbers, billing addresses, or payment credentials. We only receive cryptographically signed transaction tokens to unlock PRO features locally.

B. Advertising (Google AdMob)

Free-tier users may opt-in to watch user-initiated Rewarded Ads to extend daily reading quotas. Google AdMob may collect and process device-specific data, including:

• Mobile Advertising Identifiers (such as Google Advertising ID / GAID, subject to your reset or opt-out settings).
• Coarse IP addresses (for regional ad delivery and fraud prevention).
• Diagnostic data related to ad impressions and interactions.

AdMob processes this data under its own privacy disclosures and provides compliance mechanisms compliant with GDPR (Consent Management Platform / UMP) and CCPA / CPRA regulations.

4. Data We Do NOT Collect

To remain unequivocal, Lector does NOT:

• Require personal user accounts, passwords, or social media logins to read books.
• Upload or inspect any portion of your documents, e-books, or imported audio.
• Sell, rent, or trade your personal reading histories or behavioral metrics to data brokers.
• Use your reading text or voices to train public or proprietary machine learning models.

5. Legal Bases for Processing (GDPR)

For users located within the European Economic Area (EEA), the UK, and Switzerland, processing is conducted under the following legal bases:

• Contractual Necessity (Art. 6(1)(b) GDPR): To provide in-app PRO features and validate license receipts via Google Play Billing.
• Legitimate Interest (Art. 6(1)(f) GDPR): To troubleshoot critical app crashes and protect the security of our services.
• Consent (Art. 6(1)(a) GDPR): For non-essential personalized advertising delivered through Google AdMob, which you can grant, decline, or revoke at any time via in-app consent dialogs or device settings.

6. Your Rights (GDPR & CCPA / CPRA)

Depending on your jurisdiction, you enjoy clear legal rights over your personal information:

• Right to Erasure / Data Deletion: Because reading data is stored on-device, deleting the application or clearing application storage through Android Settings permanently purges all local data, bookmarks, and files.
• Right to Opt-Out of Targeted Advertising: You can opt out of personalized ads at any time via Android Settings: Settings → Google → Ads → Delete advertising ID or through the consent options in the app.
• Right to Access & Inquiries: You can request clarification regarding any diagnostic or purchase-related data we process by emailing support@lector.page.
• Non-Discrimination: We will never discriminate against you for exercising your privacy rights.

7. Children's Privacy

Lector does not knowingly collect personal identifiable information from children under the age of 13 (or 16 in certain jurisdictions). Because reading files remain locally isolated on the user device, children can safely utilize the reader offline without risk of content extraction.

8. Changes to this Policy

We may update this Privacy Policy from time to time to reflect operational, legal, or regulatory updates. Any revisions will be posted on this page with an updated "Effective Date". Continued use of Lector after any changes constitutes your acknowledgement of the revised policy.
