Call Blacklist

KEY FEATURES ★ Blacklist Add numbers that should always be blocked. Supports multiple flexible matching rules: - Exact match – block only that specific number - Starts with – block entire prefixes (e.g., all numbers starting with a scam area code) - Contains – block any number containing a specific pattern - Regex – advanced pattern matching for power users with custom logic Each entry can be individually enabled or disabled without ever deleting and re-adding it. ★ Whitelist Important contacts always get through. Numbers on the whitelist bypass all blocking rules unconditionally, so you never miss calls from family, doctors, or work. ★ Block History Every blocked call is logged with the number, the rule that triggered it, and a timestamp. Review your history at any time to see what calls were stopped and spot patterns in spam campaigns. ★ Blocking Rules - Block Unknown Numbers – stop calls with no caller ID displayed - Block Private Numbers – block calls marked as private or restricted - Block International Numbers – block international calls from unknown senders - Scheduled Blocking – set a start and end time for automatic blocking (e.g., only during sleeping hours) ★ Backup & Restore Export your entire configuration — blacklist, whitelist, and history — as a JSON file. Restore it anytime on the same device or transfer seamlessly to a new phone. ★ Dark Theme Built-in dark mode for comfortable use in low-light environments. ★ Privacy First Call Blacklist is designed with your privacy as the top priority: - No data collection – we never collect, transmit, or share your data - No analytics or crash reporting SDKs of any kind - No advertising libraries or third-party trackers - No network permissions requested or used - All data stays exclusively on your device HOW IT WORKS 1.
