Privacy Policy

Your privacy is our absolute priority. This Privacy Policy describes how readHD handles your information.

1. Local-First Data Principle

readHD is built on a strict local-first architecture. This means:

• No Personal Data Harvesting: We do not collect, capture, store, or transmit your custom nickname, bookmarks, highlighted text segments, ADHD brain dumps, or reading history.
• Secure On-Device Storage: All your reading progress, imported books, notes, and local AI flashcards are saved strictly within the secure application sandbox container on your physical device.

2. Device Resource Permissions

To provide our cognitive reading features, the App requests access to:

• Device Accelerometer: Used strictly on-device to recognize shake gestures to launch the ADHD Brain Dump interface. No motion sensor data is uploaded or logged.
• System Text-to-Speech (TTS): Dictation features utilize your operating system's native voice synthesizer. All voice conversion occurs locally on-device.

3. Purchases & Transactions

We use Apple App Store and Google Play Billing services to process premium subscriptions. Purchases are bound to your Apple ID and Google Play account respectively, and processed natively by the operating system platform store. No real name, email, or billing address is processed or stored directly by the readHD application.

4. Data Retention & Deletion

Because all data is stored on-device, we cannot access, retrieve, or restore your data. You can delete all your application data at any time by selecting the "DELETE ACCOUNT & DATA" option in the settings panel or by uninstalling the App.
