Evaluation phase

The tool is in a trial period, free of charge and with no commitment. The aim is to assess its usefulness as training material and to gather corrections before deciding whether it has a future. If you find wrong or missing data, I would be grateful if you let me know at the address at the bottom of this page or on X (@AlfredoRedondoD): it is the most valuable contribution at this stage.

Personal data

The email you enter is stored, together with the date, country and device type (mobile or desktop), in a database owned by the author and hosted on Cloudflare. It is used to understand who uses the tool during the evaluation phase. It is not shared with third parties or sold, and you will not receive any communications unless you request them.

Aggregate usage is measured with Cloudflare Web Analytics, which uses no cookies and identifies no one: country of origin, device type (mobile or desktop), browser and pages viewed, always as totals and never linked to your email.

To know whether the tool is used again, your browser stores only the month of your first use and the date of your last visit, and once a day sends a signal with no email or identifier that only adds to overall counters (visits per day, week and month, and whether it is opened as an installed app).

No patient data are collected: the measurements you enter in the tool are processed in your own browser and never leave it.

You can request deletion of your email address from the record by writing to the address at the bottom of this page.
