The GDPR (General Data Protection Regulation) is the European law that decides how organisations are allowed to handle people’s personal data. It applies to anyone who serves customers in the EU, whether you run a webshop, a SaaS product or a simple contact form. It took effect in May 2018 and quickly became the template that many countries outside Europe copied.
At its core the GDPR asks a few fair questions. Do you have a clear reason to collect this data? Did the person agree to it? Can they ask to see it or have it deleted? Is it stored safely? You’re expected to be able to answer all of them.
A concrete example: if your website signs people up for a newsletter, you need explicit consent, a record of when they gave it, and a working unsubscribe link. You also need to know which systems hold that email address, your CRM, your mail tool, any API you push it through, so you can remove it on request.
The same logic gets harder, and more important, the more data you keep. A big data setup that quietly merges records from many sources can identify a person even when no single table names them, which is exactly the kind of profiling the law watches closely. The safest habit is to collect less in the first place, because data you never stored is data you can never leak or have to explain.
At TopDevs we build with this in mind from day one: minimal data collection, encrypted storage, EU-based hosting where it matters, and clear documentation of where every piece of data lives.
