Audit confirmation letter redaction is the removal of third-party personal data from a confirmation kept under PCAOB AS 1215. That standard governs the auditor's engagement file. anonym.plus marks each identifier on your device, so the confirmed balance stays while the named contact goes.
When this applies
A bank or customer confirmation names a contact, an account, and a balance. You strip the contact and account before the letter joins the binder.
How anonym.plus handles it
- Open the letter in anonym.plus on your device.
- Local OCR reads a scanned, signed reply.
- The tool flags the contact name and account line.
- Keep the confirmed balance and date intact.
- Replace or mask the confirmed identifiers.
- Save the clean letter locally.
What you need to provide
- The confirmation (PDF, scan, or DOCX).
- An operator (Replace keeps the reply readable).
- Optional batch for a folder of replies.

Limitations & cautions
AS 1215 wants the file to support the audit conclusion. Keep the confirmed balance and date; remove only personal data. The tool flags identifiers, not the evidence value.
Frequently asked questions
Can it read a scanned, signed reply?
Yes. Local OCR reads the image, then flags the contact, email, or account on the page so you can clear it.
Will the confirmed balance survive?
Yes. Allow-list the balance and date. Only the contact and account data are marked.
Is the reply uploaded?
No. The app is fully offline, so the confirmation stays on your device.
