Navigate to the 'Blocked Numbers' section from the main menu or homepage quick actions. Enter the number you wish to block and tap 'Add Number'. You can also select from your contacts.

Whitelisted numbers will always bypass any blocking rules, including Do Not Disturb mode (if overrides are enabled). Add important contacts to your whitelist from the 'Whitelist' section to ensure you never miss their calls.

Block Guard requires permissions like READ_PHONE_STATE (to detect incoming calls), CALL_PHONE (to manage calls), READ_CONTACTS (for whitelisting and caller ID), READ_CALL_LOG (to display call history), and SMS permissions (for text blocking). Each permission is crucial for the app's core functionality. You can find a detailed list in our Privacy Policy.

DND mode blocks all incoming calls unless they are from whitelisted numbers or contacts (if configured in DND settings). You can schedule DND for specific times or toggle it manually.

Yes, your data is secure. Block Guard uses Android's EncryptedSharedPreferences (via androidx.security:security-crypto) to store your settings locally on your device. We do not upload your blocklists, whitelists, or call logs to any server.

Block Guard includes a Backup & Restore feature. You can find this in the main menu. Export your settings (including blocklists, whitelists, and app preferences) to an encrypted file. You can restore from this file if you reinstall the app or move to a new device. Remember to keep your backup password safe!

This dialog can appear if there's an issue accessing your encrypted settings, often after reinstalling the app due to an encryption key mismatch. The dialog provides options: 1. Try 'Import Backup' if you have one. 2. If that fails or you reinstalled, tap 'Go to Settings', navigate to Block Guard's app info, select 'Storage & cache', then 'Clear storage'. Relaunch the app (it will start fresh), then use the 'Backup & Restore' menu to import your backup file.

For the most effective text message blocking, Block Guard may need to be set as your default SMS application. This allows it to intercept and filter all incoming SMS messages directly. If it's not the default, it relies on notification access, which might not catch all messages or provide the same level of control.
