## Comprehensive GDPR Summary Guide & Cheat Sheet

The General Data Protection Regulation (GDPR) is the European Union’s landmark data privacy law, designed to protect the personal data and privacy of individuals within the EU and the European Economic Area (EEA). It also addresses the export of personal data outside the EU and EEA. Below is a comprehensive guide and cheat sheet covering the core aspects of GDPR compliance.

7. **Right to Object**: To certain types of processing, such as direct marketing .
8. **Rights Related to Automated Decision Making and Profiling**: Not to be subject to decisions based solely on automated processing .
9. **Right to Withdraw Consent**: At any time, as easily as it was given .
10. **Right to Complain**: To a supervisory authority if rights are violated .

***

### 10. International Data Transfers

* **Adequacy Decisions**: Data can be transferred to countries deemed by the EU to provide adequate protection .
