As the value of data in the digital world continues to grow, what matters is not how much data exists, but how efficient it is. First party data is data that a brand collects directly from channels where it has direct contact with its users.

This data consists of one-to-one interactions independent of third-party areas. Login events and lead collection events are examples of this.

In summary, the brand itself is both the source and the responsible party for the data.

## Why Did First Party Data Emerge?

- Browsers such as Safari, Firefox, and Chrome restricted and removed third-party cookies.
- The blocking of third-party platforms like Google, Meta, and TikTok became an important step.
- Regulations such as GDPR, KVKK, and ATT prohibited third-party platforms and brands from tracking without permission.

👉 First-party data became the only controllable, reliable, and sustainable data source.

## How is First-Party Data Used Today?

### 1. Cookieless Analytics

Cookieless Analytics is a data collection method that gathers information when a user visits any website or application without storing any cookies related to that user. Instead of storing users' personal data, anonymized and aggregated data is used.

### 2. Server Based Integration

With server-to-server conversion transmissions, first party data can be used on third-party platforms.

### 3. Privacy First Analytics

Privacy First Analytics is the ability to measure traffic without collecting personal data (PII - Personally Identifiable Information) from users visiting an application and without tracking them in the digital world. First party data is collected and used without obtaining consent permission.
