What we collect

  1. No accountsYou do not sign in, and we hold no profile of you.
  2. CalculatorsThey run in your browser. What you type is not sent to us.
  3. Traffic countsOur host gives us basic numbers, such as how many visits a page gets, so we know what people read.
  4. The contact formIf you send us a message, we keep what you type (the message, the page you name, and your email only if you give it), the time you sent it and the language of the page you wrote from, so we can check it and answer. We do not keep your IP address, and each message is deleted after a year.

Links to other sites

Our source links go to other sites, and so does our partner’s link. Those sites have their own privacy rules. A partner’s link can tell the partner that the visit came from us.
