In brief

Anyone can ask a company whether and what data about them is being processed, for what purpose, for how long, where it comes from and to whom it is disclosed. Access is generally free of charge and must be provided within 30 days (Art. 18 DPO).

What does this mean for me?

The right of access is your most important tool: it lets you find out what a company knows about you – and then assert further rights. You make the request in writing, including by e-mail.

Example

You receive advertising from a mail-order company you have never ordered from. With an access request, you find out where it got your address.
