All your diary entries, vocabulary, and settings are stored locally on your device. Nothing is uploaded to a server for permanent storage. When you use AI features (grammar correction, speech-to-text), your data is sent to our server for processing but is not saved.

Go to Settings and tap "Export Backup." This creates a JSON file you can save or share. To restore, use "Import Backup" on the same or a new device.

The AI-powered features (grammar correction, text-to-speech, speech-to-text, and conversation practice) require a connection to process your requests. Writing entries and reviewing past entries works offline.

Go to Settings and tap "Clear All Data" to delete everything. You can also delete individual diary entries by swiping on them in the History tab.

ShadowDaily uses OpenAI's services for grammar correction (GPT-4o), speech-to-text (Whisper), and text-to-speech. Your data is processed but not stored by these services. See our Privacy Policy for full details.

This usually means the server is temporarily unavailable. Check your internet connection and try again in a moment. If the issue persists, please contact us at the email above.

Go to Settings. You can adjust the shadow exercise speed, vocab speaker speed, voice tone (higher or deeper), number of repetitions, and pause durations.
