1. Practice minimal data collection
Get started the right way - by minimizing the amount of data that you’re storing. This will make life easier for you when it comes to managing the data, and ensuring compliance with data privacy legislation (more on that below).
The best way to break it down is whether data is ‘need-to-have’ or ‘nice-to-have’.
Yes, it’s true that data itself has become a need-to-have in recent years for any business conducted online, but by avoiding an accumulation of data simply because you might like to use it one day, you’ll save your back further down the line.
Instead ask yourself - is it necessary for tracking, or for the company itself to function? If you can find a solid use case for it, for invoicing, customer contact, or documentation for example, then chalk it down as a need to have. Don't be afraid to conduct more analyses if you’re unsure, such as a risk-concern analysis.
What is PII?
PII stands for personally identifiable information, which is any kind of information that can be used to identify a particular individual.
What does personally identifiable information include, exactly? Yes, the usual suspects such as name, email address, phone number, or social security.
However, PII can be pretty much anything in a certain context.
For example, if you have a group of 100 people who all visit the same store and one who does not, that information alone could be used to identify that individual.
As you’ve probably guessed, there can be some grey areas when it comes to PII, so make sure to take it on a case-by-case basis, within the context of your own business.
TIP: Keep the useful data while dropping potentially problematic PII by anonymizing it, which can even be automated by selected tools.
