Timesheet Calculator is published by Gabriel Dietsch. It is a free hours calculator on this website and inside ChatGPT. This page is the privacy policy for both.

What the calculator receives

When you calculate hours, the request can include day labels, start and end times, unpaid break minutes, an overtime threshold, an hourly rate, and a currency label. Those values are used only to compute that response.

The MCP server that ChatGPT calls uses shift times only for that calculation. They are not stored: no shift time, label, or rate is written to a database, a file, or a log. The website calculator works the same way and does not store the shift list. ChatGPT may keep the conversation under OpenAI's own policy. This server does not receive or store that chat history.

Anonymous usage counts

To see which features people use, the app records anonymous usage counts: that a calculation or CSV export ran, whether it succeeded, how long it took, how many shifts it had, and whether a rate or overtime setting was used. Page views, CSV downloads, and clicks to the ChatGPT listing are counted the same way, with a coarse flag for automated traffic. These counts never include shift times, day labels, rates, pay, names, IP addresses, or browser details.

Email updates and reminders

If you submit the form on the home page or on /timesheets, we store your email address, which of those two pages you used, and the time you submitted it in our database (Neon, hosted in the US). We do not attach your shift list to that address. We use the address to send product updates and the weekly reminder to log hours, and you can ask us to delete it at any time by emailing Gabriel Dietsch at gabriel@primecapequity.com.

To stop spam, the form keeps a short-lived, one-way hash of the sending network address for one day so it can limit repeated sign-ups. The address itself is not stored.

What we don't collect

No account, no payment card, no advertising profile, and no tracking cookies. The pages do not load third-party scripts.

How long it is kept

Shift times in a calculation are not kept by this app. Anonymous usage counts are kept to show trends. Email addresses stay until you ask for them to be deleted.

Your choices

You can use the calculator without an email. To remove an address, contact Gabriel Dietsch at gabriel@primecapequity.com from that address and ask.
