What is Data Subject Access Request (DSAR meaning)?

In today’s data privacy landscape, protecting personal information is more important than ever. One of the most effective tools individuals have to exercise their privacy rights is the Data Subject Access Request (DSAR).

But what is DSAR, exactly and why is it such a vital part of modern privacy law? Let's find out together.

DSAR meaning explained

A DSAR (Data Subject Access Request) is a formal request submitted by an individual to an organization, asking for access to the personal data that the organization holds about them.

What is DSAR (Data Subject Access Request)?

A Data Subject Access Request (DSAR) allows an individual to ask an organization for access to the personal information it holds about them. DSARs are a key requirement under privacy laws like GDPR and CCPA, designed to promote transparency and give individuals control over their data.

A DSAR empowers individuals to retrieve their personal information and understand how it's being collected, stored, used, or shared.

Purpose of a DSAR

The core purpose of a DSAR is to allow individuals to understand what data is held about them, how it’s being used, and for what reasons. It’s about making data use visible and accountable.

Why DSAR compliance matters

DSARs are essential for transparency and accountability. They give people more control over their personal data and foster greater trust between consumers and organizations.

It also:

• Demonstrates regulatory compliance
• Improves customer satisfaction
• Protects your brand reputation

DSAR vs DSR: What’s the difference?

A DSAR is a specific type of DSR that lets individuals request access to their personal data held by an organization. A DSR is a broader term that includes DSARs plus requests for deletion, correction, or restriction. All DSARs are DSRs, but not all DSRs are DSARs. Both are core to privacy compliance.

Who can make a DSAR?

Anyone, including employees, customers, partners, or legal representatives can submit a DSAR. The right applies regardless of relationship or role, so long as personal data is involved.

How to make a DSAR

DSARs can be submitted through various means, often as specified in a company’s privacy policy. These may include:

• Online forms on the organization’s website
• Email communication
• Paper forms or letters
• Social media or customer service channels

Organizations are required to clearly outline the process for submitting a DSAR in their privacy notices.

What information can be requested in a DSAR?

Scope of information

A DSAR may include:

• Copies of personal data
• Summaries of how data is processed and why it was collected
• Information about data retention, sharing, storage and transfers
• Requests for data correction, deletion, or opt-outs from certain data uses

This wide scope ensures that individuals can fully understand and manage how their personal data is used.

Beyond access

While DSARs are often associated with accessing data, they can also include:

• Correction (rectification) of inaccurate data
• Deletion (erasure) of personal data
• Objection or opt-out from specific data processing activities

Legal basis of Data subject access requests

The right to access personal data stems from privacy laws such as the General Data Protection Regulation (GDPR) in the European Union and the California Consumer Privacy Act (CCPA) in the United States.

DSAR in the context of GDPR

Under GDPR Article 15, DSARs are a key privacy right. Organizations must:

• Identify and compile relevant personal data
• Explain the purposes of processing
• Disclose any third parties with whom the data has been shared
• Respond within one month

GDPR emphasizes timely, transparent, and complete responses, with severe consequences for non-compliance.

DSAR under CCPA

The California Consumer Privacy Act also requires companies to honor DSARs from California residents. Under CCPA:

• Consumers must be informed about what data is collected
• Businesses must disclose whether data is sold or shared
• DSAR responses must be delivered within 45 days

Compared to GDPR, CCPA places greater emphasis on consumer opt-out rights and disclosure of sale practices.

How organizations respond to DSARs

Businesses must implement processes to:

• Receive the request
• Verify the identity of the requester
• Locate all relevant data (discovery and classification)
• Compile and deliver a clear response
• Track and audit DSAR activities for compliance
• Deliver the response (in plain language, often in electronic format)

Failure to do so can lead to fines, reputational damage, and loss of customer trust. Using tools like the Ketch Data Permissioning Platform can significantly streamline these steps with automation, triggers, and workflow builders.

Response obligations

Organizations are legally required to respond to DSARs within specific timeframes—usually 30 days under GDPR and 45 days under CCPA. They must deliver responses in a clear, understandable, and accessible format.

DSAR Example: IMAX

IMAX, a global entertainment company, faced challenges managing Data Subject Access Requests (DSARs) and complying with regulations like the CCPA due to resource-heavy, manual processes. To address this, they partnered with Ketch to implement an automated solution that streamlined DSAR fulfillment and consistently enforced user privacy preferences across web, mobile, and their Customer Data Platform (CDP).

Through Ketch’s consent orchestration and integration with tools like Google Tag Manager, Zendesk, and Segment, IMAX automated 80% of DSAR responses, reducing operational burden and strengthening compliance across their data systems.

“We’re impressed with Ketch’s App Marketplace. Ketch connects people’s privacy choices to our CDP and data systems—a truly comprehensive consent and rights solution.”

How Ketch simplifies DSAR fulfillment

With rising volumes of DSARs and increasing regulatory complexity, manual processes are no longer sustainable. The Ketch Data Permissioning Platform helps companies:

• Automate DSAR intake and fulfillment
• Customize workflows to match business processes
• Stay compliant across jurisdictions (GDPR, CCPA, and others)
• Respond faster, with greater accuracy and less risk

By reducing the burden of manual processing, Ketch helps companies focus on what matters most—building trust and growing responsibly.
