What this is. A short letter you can hand to your employer (or HR) explaining that you keep a personal record of messages received outside working hours. It is a transparency measure, not a confrontation โ€” it shows the record exists, what it contains, where it is stored, and why you are keeping it. Fill in the bracketed placeholders ([EMPLOYEE NAME], [EMPLOYER / HR CONTACT], [DATE]) before sending.

The template is provided as a Word document (editable) and a PDF (print-ready). Both are identical; the Word version exists so you can adapt the wording to your jurisdiction, your employment contract, or the specific request you are responding to.

2. When to send it

You do not have to send this notice to use OvertimeLog. But there are three situations where doing so is a good idea:

Conversely, if you are in the middle of a live dispute and intend to produce the record as evidence, talk to a lawyer first. Nothing on this page is legal advice.

3. What's inside

Here is the text you will see after opening the Word or PDF file:

Privacy Notice โ€” Personal Working-Time Record

1. Purpose of this notice

This letter informs you that I, [EMPLOYEE NAME], am keeping a personal record of the times I am contacted for work outside of my agreed working hours. I am providing this notice in the interest of transparency and to describe what the record contains, how it is stored, and why I am keeping it.

2. Why I am keeping this record

Under the European Court of Justice judgment in CCOO v Deutsche Bank (Case C-55/18, 14 May 2019), employers are required to establish an "objective, reliable and accessible" system for recording the daily working time of each worker. Where such a system is not yet in place on the employer side, I am maintaining an employee-side record so that my actual working time can be demonstrated if required.

3. What the record contains

The record is limited to messages I receive or send in workplace chat (for example Slack direct messages) during periods that fall outside my agreed working hours. For each message, the record captures timestamp, channel name, sender/receiver username, the message text, a permalink back to the message, and a SHA-256 hash of the captured content. It does not contain biometric data, location data, or any information outside of work-related chat messages.

4. Where the data is stored

The record is kept only on my personal device, inside a local SQLite database file. It is not synchronized to any cloud service and is not shared with any third party. The software used (OvertimeLog) operates entirely on-device.

5. Legal basis for this processing

I am processing this information under Article 6(1)(f) of the General Data Protection Regulation (legitimate interests): specifically, the interest in being able to demonstrate my own actual working time and, where applicable, to support claims for overtime compensation.

6. Retention

The record will be retained only for as long as necessary to establish or defend claims relating to my working time and overtime compensation, typically in line with the limitation periods that apply to such claims in our jurisdiction.

7. Rights of other participants

Because the record includes messages sent by colleagues who are also parties to the conversation, I recognise those colleagues have data-subject rights under the GDPR and will respond in accordance with the applicable law and in good faith to any reasonable request.

8. Availability of the record

I will make the record available, in whole or in part, in response to any reasonable request from the employer or a regulator in the context of a working-time, overtime, or compliance dispute.

9. Contact

If you have any questions about this notice, please contact me at [EMPLOYEE EMAIL].

Sincerely,

[EMPLOYEE NAME]

[JOB TITLE]
