This Privacy Policy explains how Subo - Subscription Manager ("we," "our," or "the App") collects, uses, and protects your information. Your privacy is our top priority, and the App is designed with a "Local Data First" principle.

1. Information Collection and Use

1.1 Local Data Storage All subscription-related data you enter into the App—including service names, pricing, billing cycles, payment dates, and notes—is stored exclusively on your personal mobile device's local database. We do not upload, sync, or store your personal subscription data on any remote servers.

1.2 External Data (Currency Rates) The App fetches real-time currency exchange rates from a public API provider (exchangerate-api.com) to calculate monthly spending estimates. This interaction is read-only; the App does not send any of your personal subscription details or financial data to this third-party service.

1.3 Permissions Disclosure We require specific permissions to ensure the App functions correctly:

• Internet (INTERNET): Used solely to fetch the latest currency exchange rates.
• Storage / File Access: Used to generate backup files (.json) and read files you select for restoration. On newer Android versions, this interacts with the system's scoped storage to ensure user privacy.
• Vibration (VIBRATE): Used to provide tactile feedback (haptic feedback) during user interactions, such as confirming a deletion or saving a record.

2. Data Security

2.1 Local Storage Security Since your data is stored locally, its security primarily depends on the security measures of your mobile device (e.g., screen lock, encryption). We strongly recommend keeping your device secure.

2.2 Data Backup Please be aware that uninstalling the App will permanently delete the local database stored in the App's private directory. To prevent data loss, we provide a built-in Backup & Restore feature. We recommend regularly exporting your data and saving the backup file to a safe location (such as your cloud drive or email).

3. Third-Party Services

3.1 No Tracking or Ads Subo does not integrate any third-party advertising SDKs (e.g., AdMob) or user behavior analytics tools (e.g., Google Analytics). We do not track your usage habits.

3.2 Exchange Rate Provider As mentioned in Section 1.2, we use a standard API for currency conversion. This usage is anonymous and does not involve the transmission of Personal Identifiable Information (PII).

4. App Store & Google Play Compliance

We comply with the Google Play Developer Distribution Agreement and Apple App Store Guidelines. The App does not collect Sensitive Personal Information (SPI) or Personally Identifiable Information (PII) such as your contact lists, SMS messages, precise location, call logs, or photos (outside of the files you explicitly select for restoration).

5. User Rights and Control

You have absolute control over your data:

• Access & Modify: You can view, edit, or delete any subscription record within the App at any time.
