II. Written in clear and plain language
The information should be provided in as simple a manner as possible, avoiding complex sentences and language structures.

This one-month time limit can be curtailed in the following situations: (i) when the first communication with the data subject takes place prior to the one month time frame, or (ii) when the personal data are disclosed to another recipient.
