This page explains what this site collects and what it does not. The short answer: nothing you enter is sent to this site's servers or stored by the site. In the calculators, names and dates simply stay in your browser; the friendship quiz writes your answers into a link that you send yourself, as explained below. There are no accounts, no profiles, and currently no cookies, analytics, or advertising tools. You can contact us by email about anything on this page.
We do not collect the names and dates you enter. In the calculators, those entries stay in your browser and are not sent to our servers. They are not added to the page address, either, so a result cannot be shared as a URL.
The friendship quiz in the Russian, Spanish, Portuguese, French and German versions of the site works differently: the answers and the name of the person who creates a quiz are written into its link after the # sign, and that person sends the link to their friends. Browsers do not send the part after # to this site's server, and the site does not store it. If you share the link through WhatsApp or Telegram, that service receives the full link.
There are no accounts here, and no profile is built about you.
This site currently uses no cookies, no analytics, and no advertising tools. That is the whole picture for tracking on this site as it stands today.
Two names, ten seconds, and the whole formula in the open.
