Timer is a productivity utility that generates output from your inputs without ever asking for a file. There is nothing to upload — the tool is pure math, pure pattern generation, or pure configuration — so the question of whether your data stays private is moot. Nothing you don't type goes anywhere. The result renders instantly inside the browser, and you can copy, download, or screenshot it however you like.
It is free, needs no account or email, doesn't carry a watermark, doesn't throttle how often you can run it, and keeps working offline. The whole catalog follows the same ground rules; a few tools like this one are a particularly clean case because they could not leak your data even if they tried.
