Privacy Policy & Scripture Notices

A. Data Processed & Purposes

• Local Device Storage (Default): Reading progress (bible_read_chapters), bookmarks (bilingual_bible_bookmarks), verse highlights (bilingual_bible_highlights), custom reading plans (bible_custom_reading_plans), and display/voice preferences are stored locally on your device.
• Optional Email Authentication & Cloud Sync (Supabase): If you choose to sign in via Settings → Sign In with Email, your email address is used for passwordless magic-link authentication and to synchronize your reading history, bookmarks, highlights, custom reading plans, preferences (user_bible_sync), and optional daily reminder Web Push subscriptions (user_push_subscriptions) through Supabase, Inc. (Supabase Privacy Policy).
• Text-to-Speech (TTS) Audio Synthesis: When you stream chapter audio or voice samples (/api/audio/stream), only the selected scripture verse text, language code (ta/en), voice name, and playback rate are sent to Microsoft Edge Neural TTS (edge-tts, Microsoft Privacy Statement) with Google Text-to-Speech (gTTS, Google Privacy Policy) as fallback. No personal identifiers or email addresses are transmitted with TTS requests.

B. Data Retention, Deletion & Self-Service Account Removal

• Local data remains on your device until cleared or uninstalled. You can export a portable JSON copy at any time via Export Backup.
• Cloud-synced records in Supabase (user_bible_sync and user_push_subscriptions) are retained only while you keep cloud sync active.
• Instant Self-Service Cloud Deletion: Signed-in users can permanently delete all cloud-synced records and push subscriptions at any time using the Delete Cloud Data button in Settings (⚙️) → Cloud Sync or below, or by opening a deletion request at GitHub Issues.
