The short version
The tools work in your browser. Text, numbers, files and passwords you enter are processed on your device and are not sent to our servers.
What is stored on your device
Some tools may remember a setting, such as the units you prefer, in your browser’s local storage. It stays on your device and you can clear it in the browser settings at any time.
Server logs
The site is hosted on a server of Hetzner Online GmbH in Germany. The web server keeps no log of visitors’ requests; only visits by search engine robots are logged.
Analytics and advertising
Visits are counted by the site owner’s own counter. It sets no cookie and receives only the address of the page, the page you came from, your browser and the country derived from your IP address. The IP address is used only to compute a daily hashed identifier and is not stored; the key of that hash is deleted the next day.
We also use Google Analytics 4 to see which tools are used and whether they work. Page addresses are sent without parameters, and nothing you enter into a tool is sent. Google Analytics may set cookies and process your IP address to provide the service. In the European Economic Area, the United Kingdom and Switzerland it stores nothing on your device until you allow it; elsewhere you can turn it off at any time with Privacy choices at the bottom of every page.
The site shows no advertising.
