# Input Masking & Custom Masking

Zipy's Input Masking feature ensures that all input field data on the screen is automatically masked during session recordings. This powerful feature prevents sensitive information from being visible in the recordings, safeguarding user privacy and maintaining compliance with data security standards.

Key benefits:

* Masks sensitive information to prevent unauthorized viewing
* Automatically protects input fields like passwords and personal data
* Maintains compliance with data security standards
* Ensures user privacy in session recordings

The SDK provides two types of masking:

1. **Automatic Input Masking**: Built-in protection for standard input fields
2. **Custom UI Masking**: Using `zipy_block` for additional UI elements

### Using ZipyBlock

When screenshots are captured, the masked elements will appear as black rectangles in the screenshot while remaining fully visible to the user during normal app usage.

Add the tag to do custom masking in xml files\
android:tag="zipy\_block"

```xml
<Button
    android:id="@+id/btnGetSessionUrl"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Get Session URL"
    android:tag="zipy_block"
    android:layout_marginBottom="8dp" />
```
