Overdraft notice redaction takes personal data out of a negative-balance letter. UK GDPR and the DPA 2018 limit how a bank shares customer information. anonym.plus marks each field on your machine, so the fee message stays readable while the named party's data is shielded.
When this applies
Such a letter names the account owner, the account, and the shortfall. You must hide those before the message goes to a trainer or reviewer.
How anonym.plus handles it
- Open the letter in anonym.plus on your device.
- Local OCR reads a scanned, posted page.
- It flags the borrower, account, and amounts.
- Confirm the flags and keep the fee schedule text.
- Swap or black out the confirmed fields.
- Save the clean copy locally.
What you need to provide
- The letter (PDF, DOCX, or scan).
- An operator (Replace keeps the text readable).
- Optional batch for a mailing run.

Limitations & cautions
A fee letter often repeats the account and amount in several places, so one missed line can re-link the customer. Check the whole page after the pass before you share it.
Frequently asked questions
Can I keep the fee schedule text?
Yes. Allow-list the standard fee wording so it stays while the account owner's and account data are removed.
Does the tool read a scanned letter?
Yes. Local OCR reads the posted page, then flags the account and amount fields.
Is the letter uploaded?
No. The app works offline, so it stays on your device.
