About Us
NumberDrop was built for anyone who needs random numbers without the friction.
We are a small team of developers and data practitioners who got tired of opening bloated software, signing into accounts, or wrestling with spreadsheets just to generate a batch of normally distributed values. So we built the tool we wished existed: fast, focused, and entirely browser-based.
What we believe
No signup walls
You don't need an account to generate numbers. You don't need one to export CSVs. You don't need one to save presets in your browser.
Reproducibility matters
Science, gaming, simulation, and QA all depend on knowing you can get the exact same sequence again. Seeds are first-class here, not an afterthought.
Batch work should be easy
If you need twelve different configurations, you should be able to queue them, run them, and download one consolidated file. Not twelve.
How it works
Everything runs client-side in your browser. Your data never hits our servers. The distributions (uniform, normal, exponential, Poisson) are implemented using well-documented algorithms, and the seedable PRNG ensures cross-session reproducibility.
Who it's for
Developers writing tests. Tabletop gamers rolling digital d20s. Students running Monte Carlo simulations. Data analysts who need controlled randomness. If you need numbers, drop in and get them.
Privacy Policy
Last updated: August 2026
What we collect
Almost nothing. The tool runs entirely in your browser. When you generate numbers, export a CSV, or queue a batch job, all of that processing happens on your device. It does not pass through our servers.
The only information we might receive is standard server log data that our hosting provider collects automatically: your IP address, browser type, the page you visited, and the time of your visit. We do not use this data to identify you, profile you, or sell it to anyone.
What stays on your device
If you save a preset or set a seed, that information is stored in your browser's localStorage. It never leaves your computer. If you clear your browser data or use incognito mode, those presets disappear with it. We cannot access them, restore them, or delete them for you.
Cookies and third parties
We do not use tracking cookies. We do not run third-party advertising. If we ever add analytics to understand how the site is used, we will use a privacy-respecting provider and update this policy.
Security
Because nothing you generate is transmitted to us, there is no server database of your random numbers to breach. Your outputs are as secure as your own browser.
Changes
If this policy changes, we will update the date above. Continued use of the site means you accept the revised policy.

What you don't get
This site is provided "as is" and "as available." We do not guarantee that the random numbers generated are suitable for cryptographic security, gambling, medical decisions, or any other high-stakes purpose.
