GDPR-Compliant Time Tracking: What Companies Need to Know

Why Data Protection Matters in Time Tracking

Working hours are personal data. They reveal when someone worked, for how long, and potentially what they worked on. This means every time tracking solution is subject to the requirements of the General Data Protection Regulation (GDPR).

For companies, this means: Choosing a time tracking tool is not a purely technical decision. It is also a data protection decision. A wrong choice risks fines, warnings, and above all, the trust of employees.

The Legal Basis: Why Are Employers Allowed to Track Working Hours?

The GDPR does not fundamentally prohibit the processing of personal data — it only regulates the conditions. For working time recording, two legal bases apply:

• Art. 6(1)(c) GDPR — Compliance with a legal obligation. Following the ECJ ruling, employers are legally obligated to record working hours.
• Art. 6(1)(f) GDPR — Legitimate interest. The correct accounting of working hours and overtime is a legitimate interest of the employer.

Employee consent is not required for basic working time recording, as the legal obligation is sufficient.

Principles of GDPR-Compliant Time Tracking

Purpose Limitation

Working time data may only be used for the defined purpose: documentation of working hours, compliance with legal requirements, payroll. Use for performance evaluation or behaviour monitoring is not permitted without a separate legal basis.

Data Minimisation

Only the data necessary for the purpose may be collected. Start, end, and duration of working time as well as breaks — yes. GPS tracking, keyboard monitoring, or screenshots — no.

Storage Limitation

Working time data must be deleted after the statutory retention period expires. In most EU countries, this period is typically two to three years.

Transparency

Employees must know which data is being collected, for what purpose, and how long it will be stored. A privacy notice for the time tracking solution is mandatory.

Technical Requirements for the Time Tracking Tool

Beyond the legal principles, there are technical criteria that a GDPR-compliant solution must meet:

• Data processing in the EU: All data must be stored and processed on servers within the EU. Third-country transfers (e.g., to the USA) are only permissible under strict conditions.
• Data processing agreement (DPA): A DPA must be concluded with the time tracking solution provider in accordance with Art. 28 GDPR.
• Access controls: Only authorised persons may access time data. Role-based permissions are mandatory.
• Encryption: Data must be encrypted both in transit (TLS) and at rest (Encryption at Rest).
• Deletion concept: The system must support automatic deletion of data after the retention period expires.

The Works Council and Time Tracking

In companies with a works council, it has a co-determination right regarding the introduction and configuration of time tracking systems. This means:

• The works council must be informed and involved before introduction
• A works agreement on time tracking is recommended
• The works council can request insight into the configuration and access rights

timeghost Time Tracking has already been reviewed and approved by several works councils. The transparent data processing and clear access rights significantly simplify collaboration with the works council.

Checklist: Is Your Time Tracking GDPR-Compliant?

• Legal basis for data processing documented
• Purpose of data collection clearly defined and communicated
• Only necessary data is collected (no GPS monitoring, etc.)
• Data processing takes place exclusively in the EU
• Data processing agreement concluded with the provider
• Role-based access controls configured
• Deletion periods defined and technically implemented
• Privacy notice for employees created
• Works council involved (if applicable)

Conclusion: GDPR Compliance Is Not an Obstacle

GDPR-compliant time tracking is not a bureaucratic nightmare. With the right solution, most requirements are automatically met. The important thing is that companies pay attention to EU hosting, transparent data processing, and clear access rights when selecting a tool — then nothing stands in the way of legally compliant time tracking.
