Privacy Policy

Last updated: October 13, 2026

The short version

Every tool on DevToolsCave that says it "runs in your browser" does exactly that: the text, tokens, or numbers you enter are processed locally by JavaScript on your device and are never transmitted to https://devtoolscave.com or any other server. We can't see, log, or store that data, because it never reaches us.

This page is the formal policy. If you want the plain-English version — what actually happens when you use a tool, what the site keeps, and how to verify any of it for yourself in about thirty seconds — read how your data is handled instead.

What your browser stores on your device

A few settings are saved in your browser's own local storage so the site behaves the way you left it. Today that is your light/dark theme choice, the tools you have starred as favourites and the last few tools you opened (which tools only — never anything you typed into them), a few options you last picked in some tools (such as the JSON converters' indent size or delimiter, the URL encoder's mode, or a title-case style guide — again, never your input), the list of cities you have added to the world clock — only if you turn on "Remember my last pattern on this device" in the regex tester — your last flavor, flags and pattern there (never the test data you ran it against), and — only if you click "Save" on a schema in the fake data generator — that schema (your chosen fields and their settings, such as a constant value or list you typed in; never any generated rows) under the name you gave it. This is not a cookie: local storage is never attached to a request, so these values are never sent to us or to anyone else, and they identify nothing about you. Clearing your browser's site data removes them, the world clock has a "Forget them" link that deletes its own entry directly, un-starring a tool removes it from your favourites, the homepage's "Clear recent" link empties the recently-used list, unchecking the regex tester's toggle deletes its entry the same way, and the fake data generator's "My schemas" panel can delete one schema at a time.

What we do collect

Like virtually any website, our hosting provider automatically records standard web server logs for every request (e.g. IP address, browser user agent, requested URL, timestamp) for security and reliability purposes. This site does not currently use analytics, advertising, or tracking cookies.

If that changes

If DevToolsCave adds analytics (to understand aggregate traffic) or advertising in the future, this policy will be updated first to name the specific services used, what they collect, and how to opt out where applicable.

Third-party links

Pages on this site may link to third-party sites (for example, documentation or a donation page). We aren't responsible for the privacy practices of sites we don't operate.

Contact

A contact form for questions about this policy is being added shortly. Until then there is no published address — rather than list one that isn't monitored, this section will be updated the moment the form is live.
