Privacy Policy

This page explains, in plain terms, what NumGen does and does not do with the information you enter into its random number generator, number wheel, or any other tool on this site. The short version: every number is generated entirely in your own browser. Nothing you type is ever sent to a server, and the only data this site collects is anonymous and does not identify you.

What the generator tools do with your input

Every tool on this site (the random number generator, the number generator quick-pick page, the true random number generator, and the random number wheel) uses the same underlying code, running as JavaScript in your own browser. When you type a Min, a Max, a count, or numbers to exclude, that input is used immediately by code running on your device to draw a result using the Web Crypto API. None of it is transmitted to this site's servers, logged, or stored anywhere outside your browser.

Your last-used settings (Min, Max, number type, sorting, and duplicate preference) are saved to your browser's local storage so the tool remembers your preferences if you come back later. Local storage is a standard browser feature, similar to a cookie but never sent over the network with any request; it stays on your device until you clear it through your browser's settings.

Copying results

The "Copy results" button uses your browser's standard clipboard API to copy the generated numbers directly on your device. No copy of the generated numbers is sent to or stored on this site's servers at any point.

The feedback button

Each tool page has a small "was this tool helpful" feedback control. Clicking a thumbs-up or thumbs-down sends a single anonymous signal to this site's server: which page you rated, and whether you clicked up or down. Nothing you typed into the generator's fields is included in that signal, and no cookie, IP address, or device fingerprint is stored alongside it. A flag is saved in your browser's local storage afterward so you are not asked to vote again on a later visit; that flag never leaves your device.

If you use the "Give feedback" link instead, it opens a small text form (or your own email application, as a fallback) so you can describe what was missing. Anything you choose to write and send is sent anonymously, without your email address, IP address, or any account identifier attached.

Analytics and advertising

If this site uses a web analytics service, it is a privacy-focused, cookieless option that reports only aggregate figures such as total visits, popular pages, and country-level location: it does not track individuals across visits or across other websites, and does not use cookies to do so. If this site displays advertising, the advertising network may use its own cookies or similar technology, governed by that network's own privacy policy rather than this one; this site does not share anything you type into any generator with any advertiser under any circumstances, because that content never reaches this site's server in the first place.

What this site does not do

This site does not require an account, a sign-up, or a login for any tool. It does not ask for your name, email address, or any other personal information to use any generator. It does not sell data, because it does not collect the kind of data that would be sellable in the first place: the ranges, counts, and numbers you enter stay in your browser, not on a server.

Children's privacy

This site is a general-audience tool and does not knowingly collect personal information from anyone, including children under 13. Since the tools do not ask for a name, email address, or any other identifying information, and generator input never leaves your browser, there is no personal information collected from any user, regardless of age, beyond the anonymous, non-identifying feedback signal described above.

Changes to this policy

If the way this site handles data changes, for example by adding a new feature that requires sending information to a server, this page will be updated to describe it accurately before that feature goes live. Checking back here periodically is the way to stay current, since no separate notification list exists.

Contact

Questions about this policy, or about how any of the tools on this site work, can be sent to the contact address in the feedback link on any tool page. See the random number generator, the number generator, the true random number generator, or the random number wheel for that link.

Frequently asked questions

Does NumGen store the numbers I generate?
No. Every number is generated locally in your browser using the Web Crypto API and is never uploaded to or stored on this site's servers.
Do you use cookies?
The generator tools themselves use your browser's local storage (not a cookie) to remember your last-used settings on this device. If analytics or advertising is present, see the "Analytics and advertising" section above for what that may involve.
Is it safe to use these tools for something sensitive, like a password?
The numbers are generated with cryptographically secure randomness, but this site is a general-purpose number generator, not a dedicated password manager. Nothing you generate is stored or transmitted, which is the main privacy guarantee this policy covers.
