Timesheet redaction is the removal of personal identifiers from an attendance record kept to evidence the Working Time Regulations 1998 and the National Minimum Wage Act 1998. Those rules set the hours and wage records a firm must hold. anonym.plus marks each name and reference on your device, so the totals stay useful while the worker is shielded.
When this applies
Such a sheet ties a worker to clock-in entries and a rate. You strip those identifiers before it goes to an analyst or auditor.
How anonym.plus handles it
- Open the sheet in anonym.plus on your device.
- Local OCR reads a scanned clock card if present.
- The tool flags the name, reference, and rate.
- Confirm the flags and keep hour totals intact.
- Swap or black out the marked items.
- Save the clean file locally.
What you need to provide
- The sheet (CSV, XLSX, PDF, or scan).
- An operator (Replace keeps the grid readable).
- Optional shared map so one worker maps to one alias.

Limitations & cautions
A unique shift pattern can identify a person even after the name goes. The tool flags named items, not every pattern. Review small teams before you share the file.
Frequently asked questions
Must I keep attendance records?
Yes. The Working Time Regulations 1998 and the NMW Act 1998 set the hours and wage records a firm must retain. A de-identified working copy does not change that duty.
Can it read a scanned clock card?
Yes. Local OCR reads the image, then flags the worker data for review.
Is the sheet uploaded?
No. The app is offline, so the attendance log stays on your device.
