Privacy Policy

SubPlus is engineered on a fundamental architectural principle: your recurring financial commitments, subscription names, billing amounts, and schedules belong solely to you.

The application does not maintain central user databases, does not require email registrations, and does not harvest your personal identifiable information. All records are persisted locally on your device.

When you enable optional Google Drive Cloud Backup, SubPlus interacts strictly with your private Google Drive AppData folder using the official drive.appdata scope:

• Isolated Hidden Storage: The backup file is saved into a hidden sandboxed folder inside your personal Google account. SubPlus has zero access to your Google Drive files, documents, or photos.
• AES-256 Military Encryption: Before any file is transmitted to Google Drive, it is encrypted locally on your device using AES-256-CBC with an HMAC-SHA256 tamper-proof cryptographic signature. Even Google cannot read your backup contents.
• Direct Transport: Files transfer directly between your phone and Google Drive via official Google APIs with TLS 1.3 encryption. No intermediate servers are involved.

All SubPlus Pro purchases are processed securely via Google Play In-App Billing or Apple App Store. We do not process, receive, or store your credit card details or bank account credentials.

Biometric authentication (Fingerprint, Face Unlock) is executed strictly via local OS APIs (Android BiometricPrompt / iOS LocalAuthentication). Biometric scans never leave your hardware Secure Enclave.
