Subject access requests

Answer a subject access request without uploading it anywhere.

The Subject access profile keeps the requester's own details and flags everyone else's (names, contact details, identifiers) for redaction, entirely in your browser. The file is never uploaded. Not to us, not to anyone.

The slowest, riskiest redaction job there is.

A subject access response is redaction inside-out: instead of removing one person's data, you have to keep theirs and remove everyone else's. Doing that by hand is where the time, and the breaches, come from.

It eats your calendar

Practitioners commonly report 30–60 minutes per file going line-by-line deciding whose data each name, email and phone number is. A bundle of twenty documents is a lost day.

Other people's data is your problem

Data protection law generally requires you to protect third parties' personal data when you disclose. Miss one colleague's name in a thread and the response itself becomes a breach.

The clock is statutory

Under the GDPR and UK GDPR you normally have one calendar month to respond. The redaction work is usually what makes that deadline tight.

Keep theirs. Flag everyone else's. In three steps.

The same on-device engine that powers KeptPDF's legal and healthcare redaction, inverted for subject access.

  1. Drop the file in

    It opens in the redaction editor instantly with the Subject access (DSAR) profile selected. Nothing is uploaded. The file is read straight into memory in this tab.

  2. Enter the requester

    Type their name, optionally their email, phone and your request reference. Findings that match are marked kept for subject and left readable. Every other person's details stay flagged for redaction. The matching runs on your device, and the requester's identity is never transmitted.

  3. Review, apply, download

    Walk the findings, then apply. The text under each box is permanently destroyed, and the audit certificate records the request reference and how many findings were preserved for the requester.

Strict by design

When KeptPDF isn't certain a finding belongs to the requester (a shared surname, a bare first name), it stays flagged for redaction.

The failure mode of a DSAR response is disclosing someone else's data. So the matcher only preserves a finding when the requester's name or identifiers match in full. Everything ambiguous is left for your review.

A whole bundle at once.

DSAR responses are rarely one file. Bulk Redact takes a folder or a pile of PDFs, applies the same requester to every file, and gives you one review screen across the whole batch, with a combined batch certificate at the end.

The most sensitive job, on the least exposed tool.

A DSAR bundle is by definition full of personal data, exactly the thing you shouldn't push through a cloud redaction service. KeptPDF does the detection and the redaction in your browser, so the documents (and the requester's identity you type in) are never sent to KeptPDF or anyone else. The only network traffic is a few bytes of anonymous usage counts (which tool was opened, never any content), and you can watch the whole exchange in your browser's Network tab.

Don't trust us. Watch the Network tab

Walk away with a record, not just a response.

Every redaction is independently re-read and verified: KeptPDF re-opens the finished PDF and confirms zero extractable characters remain under the boxes. The audit certificate records SHA-256 hashes of input and output, and in Subject access mode, your request reference and the count of findings preserved for the requester. It never contains the requester's name, email or phone. Pro turns it into a branded PDF you can file with the response.

Questions, answered straight.

Do my DSAR documents get uploaded when I redact them?
No. Redaction runs entirely inside your browser. The document never leaves your device and is never sent to KeptPDF or any third party. Open your browser's developer tools, watch the Network tab, and confirm it for yourself. See how to verify
How does it know which details belong to the requester?
You type the requester's name (and optionally their email, phone and your request reference) into the Subject access profile. Detection runs on your device as usual. Findings that match the requester are marked kept for subject and left untouched, while everyone else's stay flagged. The requester's identity is never transmitted anywhere, and it never appears on the certificate.
Is the automated pass enough on its own?
No. Treat it as a strong first pass that does the mechanical work. Matching is deliberately strict: anything ambiguous stays flagged for redaction so someone else's data is never accidentally preserved. Review the result before you send it, the way you'd review a junior's draft. KeptPDF is a tool, not legal advice. What must be disclosed or withheld in your case is a judgment for you or your counsel.
Can I redact a whole DSAR bundle at once?
Yes. Bulk Redact accepts a folder or a pile of PDFs, applies the same requester to every file, and lets you review across the whole batch before anything is destroyed. The batch certificate sums what was preserved.
Is it free?
Yes. Redaction (including the Subject access profile) is free with no account, no daily limit. Pro ($29/month) supports larger files and unlocks the branded, verifiable audit certificate.

Beat the deadline without betting on a cloud service.
