GDPR for websites and apps: a practical checklist

NMNorthMountain 30 May 2026 7 min read

GDPR is less scary than it sounds: be honest about what data you collect, collect only what you need, keep it safe, and let people see or delete it. This is a practical checklist — not legal advice — of what that means for a website or app.

The basics every site needs

  • A clear privacy policy: what you collect, why, and how long you keep it.
  • A cookie banner that asks before setting non-essential cookies.
  • Consent that is opt-in, not pre-ticked, and easy to withdraw.
  • Forms that collect only what you actually need.

Handling and storing data

Store personal data securely — encrypted at rest, access limited by role. Hosting in the EU keeps data residency simple. If you use third-party processors (analytics, email, payments), you need agreements with them and should name them in your policy.

Collect less, worry less: the data you never collect cannot leak, cannot be requested, and cannot get you fined. Minimisation is the cheapest compliance there is.

People's rights

Users can ask to see their data, correct it, or have it deleted, and you must be able to respond. In practice this means knowing where personal data lives in your systems — which is far easier when the app was designed with that in mind from day one.

Frequently asked questions

Does GDPR apply if my business is small?
Yes. It applies to anyone processing the personal data of people in the EU, regardless of company size. The obligations scale with how much and how sensitive the data is.
Is a cookie banner enough?
No — it is one visible part. You also need a real privacy policy, lawful consent, secure storage and a way to honour data requests. The banner alone is not compliance.
Where should data be hosted?
Hosting within the EU keeps data residency straightforward. Transfers outside the EU are possible but add legal requirements, so EU hosting is the simpler default.

Want GDPR handled properly?

We build sites and apps with EU hosting, clean consent and secure storage baked in. (Not legal advice — pair with your DPO.)
