Call Filter

About Call Filter

Call Filter is a simple and effective application for blocking unwanted calls. The app is free, does not contain ads, and does not collect or send anywhere your personal data or contacts.

Call Filter automatically blocks the following types of incoming calls:

- Advertising and telemarketing;
- calls from scammers;
- calls from debt collectors;
- obtrusive offers from banks;
- surveys;
- "silent calls', calls with instant disconnection;
- calls from numbers included in your personal blacklist, masks are supported (optional);
- all incoming calls from numbers that are not in your contacts (optional);
- all other unwanted calls.

You do not need to provide access to your contacts for the Call Filter to work!

Unlike other blocker apps, Call Filter does not require access to contacts, is easy to use and stable in operation.

The database of blocked numbers is updated several times a day. Your phone chooses its own update frequency depending on the battery charge, Internet connection speed, and type of connection (Wi-Fi, LTE, H+, 3G, or EDGE). Call Filter is designed to update the base of blocked numbers as often as possible, but without draining your phone battery, wasting unnecessary traffic or slowing down your Internet connection when you use it.
