Call Shield: Block Unwanted Calls and Safeguard Your Privacy
Take control of incoming calls with Call Shield — a powerful utility that blocks robocallers, telemarketers, and unwanted numbers using custom blocklists that operate entirely on your device.
Please Note:
Call Shield is a custom rule and list manager. It does NOT include a pre-packaged spam database or built-in caller directory. You create, import, and manage your own custom blocklists and number ranges.
Key Features:
- Block & Identify Unwanted Calls: Add specific numbers or entire number ranges (prefixes) to block or identify callers. Supports up to 200 million numbers across multiple extensions.
- 100% Offline & Private: Fully offline operation. No login required, and no data is transmitted — your privacy stays completely protected.
- Flexible Custom Lists: Easily create, import, and manage your own custom blocklists and identification ranges.
Important Notes:
- No Pre-packaged Database: Call Shield does not provide a pre-installed spam database; you need to add your own numbers, prefixes, or lists.
- Voicemail Handling: Blocked calls may still be forwarded to voicemail, depending on your mobile carrier’s policies.
- Do Not Disturb Mode: If Do Not Disturb mode is active, blocked calls may still appear silently on your Home screen or in Recents.
- Extension Setup: If Call Shield extensions don't appear immediately after updating rules, open Settings > Phone > Call Blocking & Identification to verify they are enabled.
Privacy Policy:
Call Shield does not collect, store, or transmit any personal data or call history. All blocking is handled locally on your device.
