What Is the Google Advertising ID (GAID)?

The Google Advertising ID is a unique, device-specific identifier used by apps and advertising networks on Android devices. It helps advertisers show you more relevant ads without directly revealing your personal identity. Think of it as a digital “number plate” for your device that can be reset or disabled anytime.

What Are Personalized Ads?

Personalized (or targeted) ads are advertisements tailored to your interests, search history, app usage, and online behavior.

• How it works: Data is collected via cookies, GAID, or similar technologies → a profile is created → relevant ads are shown.

• Benefits: You see ads that match your needs and interests.

• Concerns: Your online activity is tracked, which can raise privacy issues.
