The 2025 GDPR Compliance Checklist for Websites and Apps

What Is GDPR and Who Does It Apply To?

The General Data Protection Regulation (GDPR) is the European Union's comprehensive data privacy law, in force since May 25, 2018. It applies to any organisation — regardless of where it is based — that processes personal data of individuals located in the European Economic Area (EEA). This means a startup in Pakistan, a SaaS company in the United States, or an e-commerce brand in Australia must all comply with GDPR if they have EU users or customers.

Non-compliance carries severe penalties: up to €20 million or 4% of global annual turnover, whichever is higher. Beyond fines, GDPR violations can cause serious reputational damage and loss of customer trust.

GDPR Compliance Checklist for 2025

1. Appoint a Data Protection Officer (if required)

You must appoint a DPO if your organisation processes large volumes of sensitive data (health, financial, biometric), conducts systematic monitoring of individuals, or is a public authority. Even if not legally required, appointing a privacy lead is best practice.

2. Conduct a Data Audit

Map all personal data you collect, store, process, and share. Document the legal basis for processing each data type (consent, contract, legitimate interest, legal obligation), where the data is stored, how long it is retained, and who has access.

3. Publish a GDPR-Compliant Privacy Policy

Your privacy policy must clearly state what personal data you collect, why you collect it, how long you retain it, whether you share it with third parties, and how users can exercise their rights. Use plain language — GDPR requires that privacy notices be easy to understand.

4. Implement a Cookie Consent Banner

Under GDPR and the ePrivacy Directive, non-essential cookies (analytics, advertising) require explicit opt-in consent before being set. Pre-ticked boxes do not qualify as consent. Your cookie banner must allow users to accept or reject individual cookie categories.

5. Establish Data Subject Rights Procedures

GDPR grants individuals eight rights: right of access, right to rectification, right to erasure (right to be forgotten), right to restrict processing, right to data portability, right to object, rights related to automated decision-making, and right to withdraw consent. You must be able to fulfil these requests within 30 days.

6. Review Third-Party Data Processors

Any third party that processes personal data on your behalf (email marketing tools, CRMs, analytics platforms, payment processors) must have a signed Data Processing Agreement (DPA). Many major providers offer standard DPAs — check your contracts with Google Analytics, Mailchimp, Stripe, and any cloud hosting provider.

7. Implement a Data Breach Notification Procedure

GDPR requires you to notify your supervisory authority within 72 hours of becoming aware of a personal data breach likely to result in risk to individuals. If the breach is high-risk, you must also notify affected individuals without undue delay.

8. Document Your Compliance

The GDPR requires a Record of Processing Activities (ROPA) for most organisations. This is a written record of all data processing activities, the legal bases, data categories, and retention periods. It is the first thing regulators ask for during an investigation.

Common GDPR Mistakes to Avoid

The most frequent GDPR violations include relying on pre-ticked consent checkboxes, failing to honour data subject access requests within 30 days, using cookie banners that only allow acceptance (no rejection option), not updating privacy policies when adding new data processors, and missing the 72-hour breach notification deadline. All of these are easily avoidable with proper policies and procedures in place.
