Personal Data

Data which relate to a living individual who can be identified from those data or from other data which may come into the possession of the data controller. These data could include an expression of opinion about the individual or the intentions of the data controller or someone else in respect of that individual. Both facts and opinions are personal data.

Note that to be personal data, they must relate to the person and not to say, a complaint that the person has made but would include your job or the things you buy when you are shopping.
