AntiSpam was developed to help you reduce unwanted calls in a simple, automatic, and transparent way.

The app automatically blocks calls from numbers that are not saved in your contacts, allowing only known contacts to ring normally. This helps you avoid interruptions caused by unknown, commercial, or unwanted calls.

🔹 How it works

The app monitors incoming calls using official Android system features.

When a call arrives, the app checks whether the number is saved in your contacts.

If the number is saved, the call is allowed normally.

If the number is not saved, the call can be automatically blocked.

All processing happens locally on the device, with no data sent to the internet.

🔹 Full control for the user

A simple button allows you to enable or disable blocking at any time.

The app only works when the user chooses to activate it.

When disabled, the app does not interfere with any calls.

🔹 Local blocked calls list

To provide more transparency, the app maintains a local list of blocked numbers, allowing the user to:

View which calls were blocked

Have greater control and confidence in how the app works

This list is stored only on the device, is never shared, and is automatically removed if the app is uninstalled.

🔹 Privacy first

User privacy is a priority:

The app accesses contacts only to verify whether a number is saved.

No contacts are copied, stored, or shared.

No data is sent to external servers.

The app does not use ads and does not collect personal information.

🔹 Simple and efficient

Call Anti-Spam was created for people who want:

Fewer interruptions during the day

A lightweight, easy-to-use app that does exactly what it promises

Full control without complicated settings

🔹 Important to know

The functionality depends on permissions granted by the Android system.

Blocking is based exclusively on the user's contact list.

Keeping your contacts updated helps prevent important calls from being blocked.
