In short. No sign-up, no ads, no selling of data. You take a test anonymously. Everything below is the detail.
What we collect. Your answers are processed in your browser. The only thing sent to our server is which result you got, for anonymous counters: how many certificates have been issued for a test and how the classifications are distributed. They cannot tell who answered what. The certificate number is the running tally of certificates issued for that test; it is not tied to you. If you email us, we see your address and message and use them only to reply.
The name on the certificate. At the end of a test you may enter a name; it is optional. The name stays in your browser: it is printed on the certificate and inserted into the text you share. It is not sent to the server.
The certificate image. It is built in your browser and is not uploaded to the server. Where you send it next is up to you.
Server logs. Like any server, ours records the IP address, the time of the request, the page address and the browser type. We use these logs to keep the site running and to track down technical problems.
Analytics. We use Google Analytics 4, a service run by Google, to understand which tests people open and where visitors come from. It receives the address of the page you open, the site you came from, your device and browser type, your language, your approximate location (country and city, worked out from your IP address; Google Analytics 4 does not store the IP address itself) and what you do on the page: scrolling and clicks on links. Your answers, the name on the certificate and the certificate image are not sent to Google Analytics. If you open a link someone shared with you, its address contains a result code, and analytics sees that code as part of the page address. Google handles this data under its own privacy policy. You can opt out by using Google’s official browser add-on or by blocking cookies.
Cookies. The site itself stores two files in your browser: your chosen language (pll_language, one year) and a note that you have already rated a test (rated_post, five years, set only after you rate). Google Analytics adds its own: _ga and _ga_ followed by the site’s ID, kept for up to two years. They let the service tell one visitor from another without knowing who anyone is. There are no advertising cookies. You can delete or block cookies in your browser settings and the site will keep working.
Links to other sites. After a result there is a link to our partner site CoreTypes, which has its own privacy policy. The link carries only the name of the test you came from, nothing about you.
Children. We don’t ask visitors’ ages and don’t collect anything that would identify a child as a child, so we don’t have separate rules for children’s data. Mental-health tests, though, are written for adults.
