BlackList

The most professional, privacy-first call blocker for Android. No cloud. No AI. No trackers. 100% offline.

Features Feature Description Blacklist Add numbers manually, from contacts, or through an explicitly shared plain-text selection. Rules use privacy-preserving local normalization (E.164 + national); BlackList does not read Android’s shared call history or SMS inbox. Whitelist Family / priority numbers that always bypass any blocking rule. Block Unknown Reject numbers not in your contacts (uses READ_CONTACTS), or optionally silence eligible unknown calls instead. Block Private/Hidden Reject withheld / private callers, or optionally silence them instead. Block All Except Whitelist Nuclear mode — only whitelisted numbers ring. Opt-in Callback Grace After you dial a valid number, allow only that exact number to call back for 15 minutes; never overrides an explicit block. Advanced Scheduling Time-based rules with day-of-week bitmask and per-schedule trusted caller exceptions. Example: Block all except whitelist 22:00–06:00 Mon–Fri while allowing an on-call number. Overnight spans supported. Temporary Block Quick Tile User-added Quick Settings toggle for the existing one-hour local block-all override. Add it from Settings → Quick access (Android 13+) or via the Quick Settings edit menu (Android 7–12); a second tap cancels it. Temporary Exact Block Locally block one valid non-emergency number for 1 hour, 1 day, 7 days or 30 days. The active temporary-block list shows its expiry and offers one-tap cancellation; temporary allows and whitelists still win. Home-screen Stats Widget Compact local counts for blocked calls today and in total, with manual refresh and direct opening of the app. No number, contact, or call-reason content is exposed. Offline Reputation Lists Optional user-selected, bounded CSV lists with auditable source metadata and SHA-256 fingerprint. No URL fetching, automatic updates, cloud sync, or retained storage access. Exact E.164 scores from 80–100 can block only after all manual and safety policies. Blocked Log Professional local timeline of blocked calls with number, display name, reason, timestamp, and recovery actions. Retain it forever (default), or automatically remove only entries older than 7, 30, 90 or 365 days; this never changes screening rules or Android’s shared call log. Smart Notifications Optional low-priority notification for each blocked call (off by default if you prefer total silence). Material Design 3 (2026) Jetpack Compose, dynamic colors (Material You), Light/Dark/System theme, smooth animations & transitions. Localization System language by default. Full RTL support — perfect Arabic layout, plus English, French, German, Spanish, Turkish, Russian, Persian, Urdu, Hindi, Chinese, Japanese, Korean, Portuguese, Italian.
