Who makes this
Tuxedo Time Guy is built and maintained by John Polaschek, independently. It is not a company, a startup, or a venture-funded anything — it is a set of tools built properly because the existing ones mostly are not, and then kept working.
Why it exists
Timer and clock sites are among the most-used utilities on the web and among the worst-treated. The common pattern is a thin tool buried under interstitials and auto-playing video, a countdown that silently drifts when you change tabs, and an alarm that does not fire on a phone. Every tool here does the boring thing correctly first: accurate in a background tab, readable across a room, working on a phone, and loading fast enough that you do not notice it loading.
How it is paid for
The site is free and always will be. It is supported by display advertising, kept out of the way of the controls and off the pages meant for projection in classrooms. There is no premium tier holding features back, no account to create, and nothing about what you time is recorded, transmitted or sold. Your timers, alarms and clock settings live in your own browser and never reach a server.
Corrections and requests
If a tool is wrong, behaves badly on your device, or is missing something obvious, say so — the contact page has the address. Bug reports naming a specific browser and device are especially welcome, because that is exactly the sort of thing that is hard to catch alone.
