Privacy Policy

What we collect: nothing

We do not collect personal data. There is no signup, no login, no account, and no profile. We never see your name, your email, your IP address (beyond what your browser sends to our static-file host for one HTTP request), your location, or anything you paste, drop, or type into any tool on this site.

Cookies: none

We do not use cookies for tracking, analytics, advertising, or any other purpose. The site uses localStorage (a browser-local key/value store) for three small things:

• Your theme preference (light or dark mode).
• Which categories you've collapsed in the sidebar.
• Which tools you've pinned to the top of the sidebar.

That is the entire list. None of it is transmitted off your device.

Tool history: stored locally, never transmitted

Some tools save a short log of your recent inputs to IndexedDB (a larger browser-local database). For example, the JSON Formatter remembers the last 50 documents you formatted, so you can recall them later from the History page. This data is stored exclusively in your browser, on your device. It is never sent to any server. It is not synced between devices. If you clear your browser data, it is gone.

You can review or delete the history at any time from the History page or via your browser's developer tools (Application → IndexedDB → tools-history).

Analytics and third-party tracking: none

We do not use Google Analytics, Plausible, Fathom, Hotjar, or any other analytics platform. We do not embed third-party JavaScript. We do not load fonts or icons from external CDNs. No third party knows that you visited this site.

We rely on Google Search Console (which sees only aggregate, anonymised search-impression data — there is no per-user signal) to understand which tools are useful enough to rank.

Service Worker and caching

This site is a Progressive Web App. A Service Worker caches the JavaScript and HTML so the site works offline. The cache lives on your device. It is invalidated automatically on each release.

Logs at the hosting layer

The site is hosted on cPanel (a static-file host). The host's web server logs receive standard HTTP request data — IP address, user-agent, referrer, and timestamp — for the duration of a request, and these logs may be retained for a short period for security and abuse-prevention purposes per the host's standard policy. We do not access these logs, do not aggregate them, and do not export them to analytics tools. This is the only point at which any data about you exists on a server, and it is at the network layer, not the application layer.

No data sharing or selling

There is no data to share or sell. We have no agreements with advertisers, data brokers, or third parties.

GDPR, CCPA, and other privacy regulations

Because we collect no personal data, GDPR Articles 13–22 (information, access, rectification, erasure, portability, objection, automated decision-making) and CCPA "Do Not Sell" provisions do not apply in any way that would require action on our part. If you have a specific concern, contact us at the email below and we will respond within 30 days.

Open-source transparency

The full source code for this site is open-source under the MIT License at github.com/usmt-cop. Anyone can read the code, audit the privacy claims, or fork the project.

We may update this policy as the site evolves (for example, if we one day add an opt-in privacy-friendly analytics platform). Material changes will be reflected in the Last updated date at the top of this page and listed in the Changelog.
