1. Data Collection and Usage
PaSS is designed to respect your privacy.
The core functionality of the app (processing your rules, contacts, call info, calendar, and network state) happens entirely on your device.
- No Personal Data is Collected: We do not collect, store, or transmit any of your personal data, contact lists, calendar events, or call logs. Your rules are stored only on your phone and are never sent to any server.
- No Third-Party Sharing: Since we do not collect your data, we do not share it with any third parties.
- No Analytics: The app does not contain any third-party analytics or tracking code.
2. Required Permissions Explained
To work correctly, PaSS requires the following permissions.
- Standard Permissions (Contacts, Phone State, Call History)
Needed to read your SIM status, access your contacts, and read your call history. This data is only read locally on your device. - Call Redirection App
Allows PaSS to intercept outgoing calls *before* they are placed to check your rules and apply changes. - Display Over Other Apps
Required for showing the SIM selection pop-up and displaying notifications. - Calendar & Network State (Wi-Fi/Bluetooth)
Required to apply environment-based rules (e.g., muting calls during a scheduled meeting or switching SIMs when connected to a specific Wi-Fi network or car Bluetooth). Calendar events and network details are only checked locally and never transmitted.
Note on Emergency Calls: Android systems never send emergency numbers (like 112 or 911) to a call redirection app. These calls bypass PaSS entirely.
