Privacy policy
In short: the site creates no accounts, does not profile visitors and passes no data to third parties for marketing.
The calculators
Every calculation runs in your browser. The values you type are not sent to the server and are not stored. If you use the share button, the values go into the page address — they are then visible to whoever you send the link to, because the link itself carries them.
The contact form
The data you enter in the form — name, e-mail address and the text of the message — is used only to reply. It is not added to any mailing list and is not passed on.
Visit statistics
The site may use a visit counter to understand which articles people look for. What is collected is aggregate: the page opened, the referring source, the approximate device type. This data does not identify a person.
Cookies and local storage
The site uses no advertising cookies. Browser local storage may be used so that pages you have already visited keep working offline — that data stays on your device and can be cleared from the browser settings.
Your rights
You can ask for a message sent through the form to be deleted by writing through the contact form.
