Account Information: When you sign in with Google or Apple, we receive your name, email address, and a unique identifier. We use this to create and manage your account.
Bill Data: All bill information you enter (names, amounts, due dates, categories, notes) is stored locally on your device using an encrypted SQLite database.
Usage Data: We do not collect analytics, usage statistics, or behavioral data.
Calendar Data: If you enable Google Calendar sync, we create and manage events in a dedicated "Billnest" calendar. We do not read or modify your other calendars.
Billnest does NOT access your bank accounts, credit cards, debit cards, or any financial credentials.
Bill amounts and payment information you enter are user-provided tracking data only. This data is stored locally on your device and is never used to access, connect to, or interact with any external financial system, bank, or payment processor.
We use your information exclusively to:
• Authenticate your identity and manage your account
• Store and display your bill data
• Sync bill reminders with your Google Calendar (when enabled)
• Enable bill sharing with users you explicitly invite
• Send local payment reminder notifications
• Process Pro subscription purchases through your app store
Local Storage: Your bill data is stored locally on your device in an SQLite database. This data is not transmitted to our servers.
Cloud Storage: If you use the bill sharing feature, shared bill data is stored in Google Firebase Firestore with security rules that restrict access to authorized users only.
Authentication Tokens: Sign-in tokens are stored securely using platform-specific secure storage (Android Keystore / iOS Keychain).
We implement industry-standard security measures to protect your data.
We do not sell, rent, or share your personal data with third parties.
Your data may be shared only in the following circumstances:
• Bill Sharing: When you explicitly share bills with another user via an invite code, the shared bill data is visible to both parties.
• Google Calendar: When you enable calendar sync, bill data (name, amount, due date) is written to your Google Calendar.
• Legal Requirements: We may disclose data if required by law or legal process.
The App uses the following third-party services, each with their own privacy policies:
• Google Sign-In (authentication)
• Apple Sign-In (authentication)
• Google Calendar API (calendar sync)
• Google Firebase (bill sharing, push notifications)
• RevenueCat (subscription management)
We recommend reviewing their respective privacy policies.
You have the right to:
• Access: View all data stored in the App at any time.
• Correction: Edit or update your bill data at any time.
• Deletion: Delete individual bills or your entire account. Uninstalling the App removes all locally stored data.
• Portability: Your data is accessible on your device.
• Revoke Consent: You can disconnect Google Calendar sync, disable notifications, or sign out at any time from Settings.
Local data is retained on your device until you delete it or uninstall the App. Shared bill data in Firebase is retained until you revoke the share or delete your account. Authentication data is retained until you sign out.
The App is not intended for use by children under 13 years of age. We do not knowingly collect personal information from children under 13.
If you use cloud features (sharing, calendar sync), your data may be processed by Google servers located outside your country of residence. By using these features, you consent to such transfers.
We may update this Privacy Policy from time to time. Changes will be posted within the App. Your continued use of the App after changes constitutes acceptance of the updated policy.
