What is a DSAR, and does it reach data you have licensed?
By SourceX Editorial · Reviewed by Noah Loul ·
Short answer
A DSAR, or data subject access request, is a person's request to see, correct or delete the personal information a company holds about them. Whether a DSAR reaches data you have licensed depends mainly on the delivered copy: records that still identify the person can be in scope, while records properly de-identified before delivery generally fall outside these rights.
Key takeaways
- A DSAR covers personal information, so the first question for licensed records is whether the delivered copy still identifies anyone.
- De-identification before delivery is the main control, because it keeps most request rights from following records into a licensee's systems.
- If identifiable data must be delivered, the license needs a request-forwarding and deletion procedure, not just a privacy warranty.
- Your own systems still answer DSARs as usual; licensing a copy does not take the original records out of scope.
- A delivery record showing what went out, when and in what form is what lets you answer a request about licensed data accurately.
What does a DSAR actually ask a company to do?#
A DSAR asks a company to act on a person's rights over their own personal information, most often to disclose it, correct it or delete it. The term comes from European data protection law, but US privacy teams now use it as shorthand for requests under state privacy laws such as the CCPA as well.
Who can send one depends on the law that applies, and for US companies the pool is wider than many assume. California's privacy law has covered employee, job applicant and business-contact information since the exemptions for those records expired on January 1, 2023, so requests can come from staff, former staff and the contacts in your CRM, not only consumers. Each law sets its own exemptions, verification rules and deadlines, so privacy teams usually keep a written procedure per jurisdiction.
- Access or right to know: a copy of the personal information held and, under some laws, the categories of recipients it was disclosed to.
- Deletion: removal of personal information, subject to exceptions such as legal holds and records the company must keep.
- Correction: fixing inaccurate details in a profile, contact record or account.
- Opt-out: stopping certain disclosures, such as sales or sharing of personal information under some US state laws.
- Portability: a usable export of information the person provided, where the law grants it.
Does a DSAR reach records you have already licensed?#
A DSAR reaches licensed records when the delivered copy still contains personal information about the requester. The original records in your own systems stay in scope either way; the open question is the copy now sitting with the licensee.
The deciding fact is the state of the data at delivery. If support tickets went out with names, email addresses and phone numbers intact, the licensee holds personal information that you disclosed, and your obligations may include passing a deletion request along. If those identifiers were removed and the remaining text cannot reasonably be linked back to the person, many privacy laws treat the result as outside the definition of personal information.
| State of the licensed copy | Does a request likely reach it? | What you need in place |
|---|---|---|
| Identifiable: names, emails or account IDs left in | Likely yes, as personal information you disclosed | A forwarding and deletion procedure in the license, plus a record of every delivery |
| Pseudonymized: identifiers swapped for tokens while you keep the key | Often yes, because you can still link records to the person | Treat as identifiable and use the key to find and flag affected records |
| De-identified: identifiers removed, key destroyed, re-identification barred by contract | Generally no, if the applicable standard is met | A documented method, a no-re-identification clause and onward-transfer limits |
| Aggregated: counts and rates only | Generally no | Minimum group sizes so small groups cannot be singled out |
| Business records with no personal details, such as part numbers and workflow steps | No | A check that free-text fields really are free of names and contact details |
Why de-identification at delivery is the main control#
De-identification at delivery is the main control because it is the last point at which you decide what leaves your systems. After delivery you depend on the licensee's systems, contracts and good faith to find and remove one person's records, and with training data that can be difficult or impossible.
Operational records hide identifiers in places structured fields do not show. Ticket bodies carry email signatures and callback numbers, dispatch notes carry street addresses and gate codes, and Slack threads carry first names and nicknames. A cleanup that only drops the name and email columns leaves most of that in place.
De-identification standards pair technical steps with commitments. Under the CCPA, for example, information counts as deidentified only if the business takes reasonable measures so it cannot be associated with a person or household, publicly commits to keep it in that form and not re-identify it, and contractually obliges every recipient to comply. Other state laws set comparable conditions with differences counsel should check. Write the recipient's commitments into the license, where a privacy team can point to them, rather than leaving them in correspondence.
What should the license say about data subject requests?#
The license should say what kind of data was delivered and what happens if personal information turns up anyway. Counsel usually asks for terms that still work if the de-identification was imperfect, because no review of free text catches everything.
- A description of the de-identification standard the delivered records meet, with a supplier warranty that it was applied.
- A promise from the licensee not to re-identify anyone or link the records with other data to do so.
- A duty to notify the supplier if personal information is found, with an agreed path to remove it.
- A cooperation clause for data subject requests covering any identifiable records, including deletion from the licensee's dataset copies.
- Limits on onward transfer, so the records do not reach parties you never vetted.
- Deletion of dataset copies at the end of the term, confirmed in writing.
How to answer a DSAR when some records were licensed#
A DSAR involving licensed records is answered the same way as any other, with one added step: checking the delivery record. That step is only possible if you kept one.
Access requests raise one more point. Some laws let people ask which categories of recipients received their information, so if identifiable records were licensed, your privacy notice and your response may need to reflect that disclosure.
- Step 1: verify the requester and log the request under your normal procedure.
- Step 2: search your own systems, such as the help desk, CRM, email archive and billing system, and act on the request there.
- Step 3: check the delivery manifest and privacy record for each licensed package to see whether the requester's records were included and in what form.
- Step 4: if the package was de-identified, record why it no longer relates to the requester and have counsel confirm how to describe that in the response.
- Step 5: if any package was identifiable, send the request to the licensee under the license procedure and keep its written confirmation.
- Step 6: close the request with a note linking the response to the delivery record you relied on.
Illustrative: a scheduling software company receives a deletion request#
Illustrative: a fictional appointment scheduling software company licensed several years of support tickets from Zendesk, with related account notes from HubSpot. Before delivery it removed names, email addresses, phone numbers and signatures, replaced customer account names with random tokens, destroyed the token map and had a reviewer sample the free text.
Months later, a former customer administrator asks the company to delete all of her personal information. The privacy lead deletes her contact record in HubSpot and her requester profile in Zendesk, then opens the privacy record for the licensed package. It shows that every identifier she could be found by was removed before delivery and that no mapping back to her account exists.
With counsel, the company concludes that the licensed copy no longer relates to her and answers on that basis. The rule it records for future packages: keep the same de-identification standard, and keep each delivery manifest for as long as the license and its survival terms run.
How SourceX handles request rights in a transaction#
Request rights are mostly settled before delivery, in the Preparation step of the SourceX five-step transaction, which runs Supply, Rights, Preparation, Approval and Delivery. SourceX removes personal and confidential details at that stage, and the supplier approves the prepared package before anything leaves its control.
The privacy record sits in the SourceX Evidence Packet next to provenance, licensing rights, permitted use and release authorization. When a DSAR arrives, it is the page a privacy team needs first, because it shows what was removed, by what method, and in what form the records went out.
Frequently asked questions
Do DSARs cover employees' Slack messages that were licensed?
They can, depending on the laws that apply to your workforce and whether the delivered messages still identify anyone. California's privacy law now reaches employee and applicant records, and California's privacy regulator opened preliminary rulemaking on employee data in April 2026. Removing names, handles, signatures and personal details before delivery, and excluding direct messages, keeps most employee requests from reaching the licensed copy.
Can a person make an AI developer remove their data from a trained model?
Usually the request runs through the company that disclosed the data, and the outcome depends on the law and the license. Removing one person's influence from trained model weights is technically hard, so licenses tend to focus on dataset copies and output restrictions. De-identifying before delivery avoids most of this question.
Does a request from someone in Europe change the analysis?
It can. GDPR treats pseudonymized data as personal data for anyone who can link it back to a person, and it treats data as anonymous only when nobody can identify the person by means reasonably likely to be used. If your records include people in the EU or UK, counsel should assess the delivered copy against that standard, since a US de-identification method may not be enough on its own.
Should our privacy notice mention data licensing?
If you license identifiable personal information, your privacy notice likely needs to describe that disclosure and any related opt-out rights. If you license only de-identified records, it is still worth reviewing the notice so it accurately describes how you use and share data. Counsel should check the wording against the laws that apply to you.
What should we keep about each licensed delivery?
Keep the delivery manifest listing record families and date ranges, the de-identification method and review results, the release approval and the signed license. Keep them for at least as long as the license and its survival terms, in line with your retention schedule. Without them, you cannot show what a licensee received.
