Data storage

With the exception of the game Minesweeper, no information that is entered into our tools gets stored on our servers. The tools run entirely inside the web browser which means that the information is never even transferred over the Internet.

Note that many tools automatically append the information that has been entered, to the address bar (after #), to make it easy to link to the tool with pre-filled input fields. If you want to link to a tool without sharing your information you should make sure that the address does not contain anything after the # symbol. The easiest way to accomplish this is by reloading the tool by clicking on the tool link in the navigation bar at the top of the page.

If you submit your name to the high score lists in the game Minesweeper then your IP address ( will also be sent and stored on our servers to allow us to prevent spam and cheating effectively. The information is stored up to one year.
