# Tags

## Overview

Tags in Android applications label and categorize users based on their app interactions or preferences. These tags enable targeted messaging and segmentation for personalized user engagement.

## Use Case

1. **Purpose**:
  - Categorize users into meaningful segments (e.g., "Dog Owners," "Frequent Shoppers").
  - Enable dynamic push notifications based on user-defined tags.
2. **Benefits**:
  - Simplify user segmentation for marketing campaigns.
  - Increase user engagement by delivering relevant content.

## Implementation Details

1. **Add a Tag**:
  - Assign a tag to a user device.

```java
// Add a tag
Appoxee.instance().addTag("DogOwner");
```
2. **Remove a Tag**:
  - Remove an assigned tag from a user device.

```java
// Remove a tag
Appoxee.instance().removeTag("DogOwner");
```
3. **Fetch Device Tags**:
  - Retrieve all tags associated with a user device.

```java
// Fetch all tags
Set<String> tags = Appoxee.instance().getTags();
```
4. **Clear Tags Cache**:
  - Clear cached tags on the device.

```java
// Clear tags cache
Appoxee.instance().clearTagsCache();
```

> [!NOTE]
> Keep in mind:
> 
> - Tags are app-specific and allow for multiple tags per user device.
> - Use meaningful tag names to simplify campaign management.
> - Test tag addition, removal, and retrieval processes for accuracy.
