Information We Collect
Notes, titles, and formatting you create are stored locally on your device (Room database) by default.
If you enable cloud sync or sign in with Google, related data is processed via Firebase.
When you use AI writing/summary features, the text you select is sent to an AI service to generate content.
Subscription/purchase is handled by Google Play; we never receive your card number.
We may show rewarded ads via AdMob, which may use the advertising ID for personalization.
Biometric Data: App lock uses device biometrics locally; we never share it with any server.
How We Use Information
To provide, maintain, and improve note-taking, AI writing, and membership; ads support the free service.
Sharing
We do not sell personal data, except with necessary processors (Firebase, AI provider, Google Play, AdMob).
Your Rights
Delete all local and cloud data and delete your account anytime via "Clear All Data (Local & Cloud) and Delete Account" in Settings. To permanently delete your Firebase account and all associated data, use the same option in Settings or email us with the subject "Deletion Request". You can reset your advertising ID or disable personalization in your device's system settings.
