Swedish Authority for Privacy Protection

What it handles: supervision of how companies and authorities handle personal data, complaints from individuals, personal data breaches and guidance on GDPR.

How to reach it: phone, email or the complaint forms on imy.se, which has guidance in English on your rights as a data subject.

Where people get stuck: IMY's English pages explain your rights as a data subject, such as asking an organisation what data it holds on you; start with that organisation, and complain to IMY if it does not handle your data correctly.
