Privacy and data protection have become increasingly important in today’s digital landscape. This guide will walk you through the process of developing a GDPR-compliant app in 2024.

What is GDPR?

The General Data Protection Regulation (GDPR) is a comprehensive set of regulations that govern the protection of personal data for individuals in the European Union (EU) and the United Kingdom (UK). It was implemented in May 2018 to replace the outdated Data Protection Directive.

The objective of GDPR is to give individuals control over their personal data and provide guidelines for companies to follow when collecting, processing, and storing it. 

Non-compliance with GDPR can result in severe penalties, making it crucial for software developers to understand and implement GDPR principles in their projects.

GDPR EU 🇪🇺 vs GDPR UK 🇬🇧

After Brexit, the UK implemented its own version of GDPR called GDPR UK. GDPR UK closely mirrors the EU GDPR, with some specific provisions to account for the UK’s separate jurisdiction. Both GDPR EU and GDPR UK aim to safeguard personal data and ensure privacy rights.

GDPR Personal Data

The EU’s General Data Protection Regulation defines Personal Data as any information related to a person that can be used to directly or indirectly identify them.

GDPR Data Processor vs Data Controller

Under the GDPR, there are two main roles: Data Controller and Data Processor. 

The Data Controller decides why and how personal information is used, while the Data Processor uses the personal information on behalf of the Controller.

Both have distinct roles and responsibilities. The Controller determines the purpose and method of using personal information, while the Processor follows the Controller’s instructions as laid out in a contract.

In simple terms, the data controller is like the boss who decides how personal data should be handled, while the data processor is like the employee who does the actual work of processing the data according to the controller’s instructions.

GDPR Data Processor vs Data Controller Responsibilities:

1. Data Collection: Data controllers are responsible for collecting personal data and must have legal authority to do so. They are also responsible for creating a GDPR privacy policy.

2. Contracts: Data controllers select GDPR-compliant data processors and create contracts that outline how data should be processed. Data processors are legally obligated to follow the instructions of the data controller.

3. Liability: Data controllers are liable for the collection, usage, and disposal of personal data. Data subjects can submit queries or complaints to either the controller or the processor.

4. Security: Both data controllers and processors must follow GDPR-compliant security practices to protect data from unauthorized access, loss, disclosure, or destruction.

5. Transparency: Data controllers are responsible for maintaining transparency throughout the data life cycle, from collection to deletion.

6. Recordkeeping: Data controllers must keep records if they process sensitive information or have more than 250 employees.

7. Reporting Data Breaches: Data controllers must notify the supervisory authority and data subjects within 72 hours of discovering a data breach that could impact data subjects’ rights and freedoms. Data processors must notify affected data controllers of any security breaches they discover.

Main Provisions of the GDPR

1. Extraterritorial application: GDPR applies to any organization that processes the personal data of individuals in the European Union, regardless of the organization’s location. This means that companies outside of the EU must also comply with GDPR if they handle EU citizens’ personal data.

2. Enhanced individual rights: GDPR gives individuals greater control over their personal data. It introduces new rights, such as the right to be forgotten and the right to data portability, allowing individuals to request the deletion or transfer of their personal data.

3. Consent requirements: GDPR requires organizations to obtain freely given, specific, informed, and unambiguous consent from individuals before processing their personal data. It sets a higher standard for consent than previous regulations.

4. Data breach notification: GDPR introduces mandatory data breach notifications. Organizations must notify the relevant supervisory authority and affected individuals within 72 hours of becoming aware of a data breach that is likely to result in a risk to individuals’ rights and freedoms.

5. Data Protection Officers (DPOs): Under GDPR, certain organizations are required to appoint a DPO. This person is responsible for overseeing the organization’s data protection strategy and ensuring compliance with GDPR.

6. Fines: GDPR introduces significantly high fines for non-compliance. Organizations can be fined up to 4% of their global annual turnover or €20 million, whichever is higher. This serves as a strong deterrent for organizations to prioritize data protection.

7. Privacy by design and default: GDPR mandates that organizations implement privacy by design and default principles into their systems and processes. This means that privacy considerations should be integrated from the start when designing products or services, and privacy settings should be set as the strictest by default.

8. Data Transfer Mechanisms: GDPR introduces strict rules for transferring personal data outside of the EU. Organizations can only transfer data to countries that have been deemed to have an adequate level of data protection or by using certain approved mechanisms such as Standard Contractual Clauses or Binding Corporate Rules.

9. Accountability and documentation: GDPR places a great emphasis on accountability and requires organizations to demonstrate compliance with the regulation. This includes maintaining detailed documentation of data processing activities and conducting data protection impact assessments for high-risk processing activities.

10. Data protection impact assessments: GDPR introduces the requirement to conduct Data Protection Impact Assessments (DPIAs) for processing activities that are likely to result in a high risk to individuals’ rights and freedoms. This helps organizations identify and mitigate potential risks to individuals’ privacy.

NOTE: GDPR rules for healthcare apps do not typically differ from the general rules applied to other types of apps. However, healthcare apps may handle sensitive personal data related to an individual’s health, which requires additional safeguards and measures to ensure compliance with data protection regulations.

What is the impact of GDPR on software owners? 

Project owners who handle the personal data of EU citizens must protect their users’ data and adhere to GDPR regulations. 

This requires the reevaluation of software development strategies to ensure compliance. 

Developers need to understand how to handle user data, including collection, transmission, storage, and management. Reviewing and enhancing data protection measures is crucial to creating software or mobile apps that meet GDPR requirements. 

NOTE: While the regulation provides general guidelines for software development, it does not provide a specific detailed guide. 

However, there are various security frameworks that provide detailed guidance for the effective implementation of security requirements. Some of the popular ones include NIST, CIS, COBIT, HITUST, etc. Due to the complexity of this subject, we will delve into this in our upcoming article.


Looking ahead, at Gera-IT, we recommend referring to the established security frameworks, such as the National Institute of Standards and Technology (NIST) recommendations and The Health Information Trust Alliance (HITRUST) for Healthcare software development. 

A Comprehensive Guide to Develop GDPR Compliant Apps by Gera-IT Developers

Developing a GDPR-compliant app will require careful attention to privacy and data protection regulations. Here are the key steps to follow:

1. Data Minimization: Collect and process only the data necessary for your app’s functionality. Pay special attention if your app collects email addresses, usernames, passwords, installation IDs, analytics stats, user-generated content, or personal information for shipping purposes. Ensure that any third-party data storage services you use are GDPR compliant.

2. Privacy by Design: Implement privacy protections, such as data anonymization, pseudonymization, and employee access controls, from the initial design stages of your app. Privacy should be an integral part of your app’s architecture, not an afterthought.

3. Consent Management: Obtain user consent before collecting and processing personal data. Make sure the consent request is clear, specific, and granular. Offer users the ability to withdraw their consent easily and manage their preferences.

4. Data Protection: Implement strong security measures to protect personal data against unauthorized access, disclosure, or alteration. Encryption should be used for both data at rest and in transit. Regularly update and patch your app to address any security vulnerabilities. 

5. Data Breach Management: Implement mechanisms to detect, respond to, and report data breaches promptly. Have processes in place to assess the severity of breaches, notify supervisory authorities, and inform affected users as required by GDPR.

6. Data Retention and Deletion: Define data retention periods based on the purpose for which the data is collected. Ensure that personal data is kept only for as long as necessary. Implement mechanisms to securely delete personal data when it is no longer needed.

7. Transparent Data Practices: Maintain transparent and easily accessible privacy policies and terms of service. Provide clear information about the purpose of data collection, processing, and sharing. Be transparent about any third parties with whom data is shared.

8. Third-Party Services Verification: Verify that any third-party services you rely on are GDPR compliant and sign a Data Processing Agreement with them as required by GDPR.

9. User Access Controls: Implement multi-factor authentication (MFA) to verify the legitimate owner of an account using multiple factors such as ownership, knowledge, and inherent factors. Use role-based access control (RBAC) and require strong authentication measures to protect sensitive data. 

10. Ongoing Compliance: Continuously monitor and audit your app’s data processing activities. Regularly review and update policies, procedures, and technical measures to ensure ongoing compliance with GDPR requirements.

Summary

Overall, Developing a GDPR-compliant app requires a thorough understanding of the GDPR principles and a commitment to protecting users’ personal data. 

By following these steps, you can develop an app that respects user privacy, meets the requirements of the GDPR, and builds trust among users. Remember that GDPR compliance is an ongoing process, and staying updated with any regulation changes is crucial to ensure personal data protection.

Non-compliance can result in severe penalties and fines for businesses. Moreover the fines are not the only consequence of non-compliance or data breaches under the GDPR. 

Organizations may also face reputational damage, loss of customer trust, legal action by affected individuals, and potential supervisory authority enforcement actions, such as audits or orders to cease processing personal data.
