Privacy, in plain words.

Your market figures

Sales, costs, event names and hours entered into the calculator stay in your browser. We do not send them to our server. A CSV export is generated on your device. The downloaded Excel prototype works as a local file.

Anonymous usage counts

We record whether an anonymous browser opens the page, edits a number or clicks the workbook download. A random identifier is stored in your browser and hashed before storage on our server. We also record a broad referral category, such as a community link or direct visit, and a timestamp. Counts are approximate and may include bots. They are not verified people or purchases.

Usage counts are disabled when your browser sends Do Not Track or Global Privacy Control. Review links with review=1 also disable usage counts.

Optional feedback

If you submit the feedback form, we store the four selected answers, the broad referral category, a timestamp and the hashed anonymous identifier. We keep one current response per browser, so submitting again updates your answers. We do not request names, email addresses, contact details or financial figures.

The form is optional. The calculator and download work without submitting it. Stated willingness to pay is recorded as interest only, not as a sale.

Public results

The results page shows aggregate counts. It does not expose browser identifiers or individual response records. We use the feedback to decide whether to develop a paid workbook.

Your browser storage

Clearing this site’s local browser storage removes its random identifier from your device. It does not remove an earlier anonymous response from our server, and a later visit may be counted again. No advertising trackers, mailing lists or paid checkout are included in this prototype.
