What you type here never leaves your device. Every one of these tools is compiled to WebAssembly and runs inside this browser tab. There is no server to send anything to, and none of them makes a network request while it works. You can open your browser's network panel and use any of them: nothing goes out.
The habit grid, the time entries, the list of names and the tasks in the matrix are all things about people. All of them are read, worked out and forgotten when the tab closes. There is no account, no history, no profile and no server — which is worth saying plainly, because the opposite is the norm in this whole category.
It also means a shared link carries what is in it. A link to a split contains the names; a link to a time sheet contains the day. That is visible in the result before you share it.
Eight of this group's tools are a button, a clock, a camera or a microphone: a click counter, a multi-tally counter, a clicks-a-second test, a reaction timer, a webcam mirror, a screen flashlight, a clipboard history and a room noise meter. None of them is here, and the reason is not only that this page is a function from one text to one result. No tool here asks for a camera or a microphone, and the browser never prompts, because there is no code that could use one. Nothing watches the clipboard, and nothing runs while the tab is in the background.
Five more became the half of themselves that is a function — a running order rather than a countdown, a schedule rather than an alarm, a total rather than a stopwatch — and each says which half it is on its own result.
The decision matrix, the pros-and-cons list and the Eisenhower matrix are arithmetic on a judgement you made. That makes the judgement visible and does not make it right, and none of them says which option to take. Where the arithmetic can add something honest it does: the matrix says when the top two are within a twentieth of each other, which is a matrix that has not decided anything.
A browser reports pixels, not millimetres. The same page is a different width on a phone, a laptop and a television, and no interface reachable from here gives the panel's real size. So the ruler and the protractor print at the size they state, and the on-screen half is a calibration you do yourself against a bank card, which is 85.60 mm by ISO 7810. Nothing is guessed from the window size, and nothing about your screen is sent anywhere.
Each tool remembers your settings, and remembers your input while it is small
enough to be worth keeping, under about eight kilobytes. It is kept in your
browser's own localStorage, on your machine, and is never
transmitted. Clearing your browsing data removes it, and a private window keeps
nothing at all. Your chosen language and theme are stored the same way.
No account, no sign-up, no cookies of our own, no analytics script, no fingerprinting, no error reporting. The pages carry no third-party JavaScript except the advertising described below.
These pages carry advertising, which is what pays for hosting them. An advertising network sets its own cookies and sees your IP address and the page you are on, in the same way it does on any other site. It does not see what you type into a tool: that text is never part of the page's markup and is never sent anywhere. If you would rather it saw nothing at all, an ad blocker breaks none of the tools.
A life counter, a quiz buzzer and an escape-room timer are not here. All three keep a state and run a clock — a counter you press, four keyboards racing to a millisecond, a countdown on a projector — and a tool here is a function from one text to one result. Five more became the half of themselves that is a function: a scramble rather than a timer, an average of the times you type rather than the times it takes. Each of those says which half it is on its own result.
The same tools are also built as a desktop application. It has no network code at all — not for updates, not for anything — and stores its settings in one small file in your user configuration directory.
If this ever changes, this page changes with it, and the change will be visible in the project's history rather than announced quietly.
