Short version: the stopwatch never leaves your browser
Privacy Policy
Stopwatch Online (stopwatchonline.xyz) is a free online stopwatch. This page explains, in plain language, exactly what happens to your data when you use the site: what runs entirely on your own device, what a privacy-friendly analytics service records in aggregate, and what an optional feedback form does and doesn't store. There is no account system, no login, and no tracking of individual visitors across sites.
The stopwatch itself: nothing leaves your browser
Every part of the stopwatch, when you press Start, Pause, Resume, or Reset, every lap you record, and the fullscreen display, runs entirely with standard web technology inside your own browser (JavaScript's built-in clock). None of that is ever sent to a server. If you close the tab or refresh the page, the elapsed time and every lap you recorded are gone, because they were never stored anywhere outside your browser's memory in the first place.
What is stored locally in your browser
The only thing this site saves between visits is your light/dark theme preference, stored using your browser's localStorage, a small, standard mechanism built into every modern browser that keeps a preference on your own device only. It is not a cookie, it is not sent to any server with each page request, and it is not accessible to any other website. You can clear it at any time through your browser's own site-data or privacy settings; the theme simply resets to your system's default the next time you visit.
Cloudflare Web Analytics (aggregate, no cookies)
This site uses Cloudflare Web Analytics to understand overall traffic (roughly how many people visit, which pages, and which country or browser they're using), the same way almost any published website measures its own traffic. It's built specifically to avoid tracking individuals: it does not use cookies, does not fingerprint your device, and does not build a profile tied to you personally. The data Cloudflare aggregates is used only to see overall trends, for example, whether a page is getting any visitors at all, never to identify or follow a specific person across visits or across other websites.
Feedback: thumbs up/down and the "Give feedback" link
Below the tool on this site there is an optional thumbs-up / thumbs-down button. Clicking it sends an anonymous signal (just the tool name and your vote) to this site's backend, purely so responses can be tallied; no email address, IP address, or browser user-agent string is stored alongside it.
The "Give feedback" link below the tool currently opens a pre-addressed email in your own email application, to contact@stopwatchonline.xyz. Whatever you choose to send is a normal email like any other you send someone, not a submission to a form on this site.
No accounts, no third-party ad trackers
There is no sign-up, no login, and no user account of any kind on this site, there is nothing to create and nothing tied to your identity to begin with. Stopwatch Online does not run third-party advertising trackers, retargeting pixels, or social-media "share" widgets that quietly track visitors on other sites' behalf. If that ever changes, this page will be updated to say so plainly, in the same style as the rest of it.
Server logs (standard web hosting)
Like effectively every website on the internet, the infrastructure this site runs on (Cloudflare) keeps short-lived, standard technical logs of requests (such as IP address and timestamp) for security and reliability purposes, for example, detecting and blocking abusive traffic. This is a routine part of how web hosting works everywhere, is not used to build a profile of you, and is not the same thing as the aggregate analytics described above.
Your rights and how to contact us
Because this site doesn't collect personal data tied to an account, there is very little to request access to or deletion of in the first place, your theme preference lives only in your own browser, and feedback messages aren't linked to your identity. If you have any question about this policy, or a concern about how the site handles data, contact contact@stopwatchonline.xyz.
A note for visitors in the EU/UK and California
Regulations like the GDPR (EU/UK) and CCPA (California) exist to give people control over personal data collected about them. Because this site was deliberately built to avoid collecting personal data in the first place, no accounts, no tracking cookies, no cross-site trackers, and an analytics service specifically designed not to identify individuals, there is very little for those regulations to apply to. The technical, security-focused server logs described above are the same routine logging every hosted website generates, kept only briefly and only for abuse prevention, not compiled into a profile about any individual visitor.
Changes to this policy
If this policy changes, for example, if a new feature is added that handles data differently, this page will be updated to reflect it, in the same plain, specific style as the rest of this document rather than vague boilerplate. There is no mailing list or notification system to subscribe to; checking back on this page is the way to see the current version.
