Offline Call Filter

Filter incoming calls offline using custom rules. No tracking, no cloud.

Offline Call Filter lets you block or allow incoming phone calls using simple, customizable rules.
The app works completely offline:
• No internet connection
• No accounts
• No tracking
• No external services
You define your own rules using phone number patterns (for example prefixes or wildcards), and the app decides whether to allow or block each incoming call.
Key features:
• Offline call filtering
• Custom allow and block rules
• Wildcard support (e.g. +39*)
• Local call history (allowed and blocked)
• No ads
• No analytics
• No cloud
Privacy first:
All data stays on your device.
The app does not collect, store, or transmit personal information.
Note:
To function correctly on some devices, Android may require contact access so the system can properly intercept incoming calls. Offline Call Filter does not read, store, or upload your contacts.
Simple, transparent, and fully offline.
