Using Municipal Personal Data Beyond Its Purpose: Mistakes with Social Assistance Data

Social assistance is a major municipal activity involving income, health, family structure, disability and
social support needs: extremely sensitive personal data
are processed in these services.
In the Board’s practice, processing social assistance data is therefore regarded as
the highest-risk data processing area.

When examining Board decisions and audit practices published until 2025,
a substantial proportion of the most serious municipal violations stems from
using social assistance data for purposes other than those for which they were collected.
In this article, we respond to the question "where are mistakes made?" in a systematic framework.

Critical fact:
The breach of purpose in social welfare data creates a loss of trust that is often impossible to compensate for. Why is Social Welfare Data So Sensitive?

Data processed in municipal social assistance procedures are,
under KVKK, not merely personal data but,
in many cases, special categories of personal data or
high-risk data categories directly revealing a person’s social circumstances.

• Income and poverty information
• Health status and disability data
• Family circumstances, including dependants
• Social support history

What is use beyond the original purpose?

Use beyond the original purpose means using personal data
outside the explicit, legitimate purpose for which they were collected
for another activity.
In social welfare data, this violation often arises on "good faith" grounds;
But the legal outcome does not change.

The KVKK principle is clear:
Good intentions do not make use beyond the original purpose lawful. Most Common Misuse Mistakes in Municipalities 1) Sharing Social Assistance Data with Other Units

One of the most common violations is sharing data collected by the social assistance unit
with municipal enforcement, legal, press or other administrative departments
in a general and unrestricted manner.

• The legal reason for sharing is not clear
• Uncertain grounds such as "institutional need"
• Failing to record data sharing

2) Use of Social Assistance Data for Audit or Disciplinary Purposes

The Board regards it as clearly problematic when data collected during an assistance application
are subsequently used in procedures concerning staff or citizens:
disciplinary proceedings, investigations or sanctions are examples of these procedures
.

3) Use of Social Assistance Data for Communication and Promotion

Contact information of persons receiving assistance;

• Invitation to municipal events
• Promotional messages
• Communications involving political or perception management

The use for it is one of the most severe categories of violations.

Social assistance data
are not a tool for promotion or visibility. 4) Long-term and Unreasonable Retention of Aid Data

After the end of their welfare application,
retaining data in the system for unlimited or unspecified periods
breaches purpose limitation and data minimisation.

• Failure to delete data of people whose application was denied
• Keeping records despite the end of the benefit period
• No automatic deletion policies

5) Unauthorized Access to Sharing Social Assistance Data

Allowing access to social assistance systems
for staff who do not need it for their duties
is considered, under KVKK, a high-risk security breach.

6) Privacy notices failing to reflect actual data use

In many municipalities, social assistance privacy notices
state only the purpose of assessing assistance applications;
But actual use goes far beyond that.

• The departments receiving data are not identified
• The retention period is not written clearly
• The rights of the person concerned are not described in a practical manner

7) Sharing Social Assistance Data with Affiliates or Third Parties

With social services software, call centers or external support firms
in the work done;
the distinction between data processor and data controller is often not made.

Third-party risk in welfare data,
It is the area with the highest inspection sensitivity. Why Are Violations So Common in Social Welfare Data?

• Well-intentioned but disproportionate practices
• Skipping legal analysis due to service pressure
• Data owners are unable to object
• Weakness of corporate audit mechanisms

What Should Municipalities Do? (Abstract Road Map)

• Separate and detailed data inventory must be created for social assistance data
• Purpose definitions should be narrow, clear and written
• Restrict data-sharing points and permissions by role
• Automate retention and disposal policies
• Special awareness and ethical training for staff should be conducted

Conclusion

Municipal social assistance data constitute
an area with legal dimensions as well as ethical and social-trust dimensions that make it
extremely sensitive.
Use beyond the original purpose
goes beyond a legislative violation:
it creates a risk of permanent harm to institutional reputation.

Protecting social assistance data
is not only a matter of KVKK compliance for municipalities;
it is also a fundamental part of public responsibility.
