Nifty Utilities

Your data never reaches us.

Nifty Utilities is a static website. It has no application backend, database, user accounts, upload service, or form submission endpoint. There is no Nifty Utilities system capable of receiving, viewing, capturing, or storing the files and information you enter into these tools.

Calculations and file processing happen inside your web browser on your device. Your inputs are not transmitted to Nifty Utilities.

Local storage

The Net Worth Tracker can save information in your browser's local storage so it remains available on that device. That information still does not leave your browser. You can remove it with the tool's clear button or your browser settings.

Downloaded libraries

A few advanced tools download software libraries from a public content delivery network. The libraries run in your browser; Nifty Utilities does not send your tool inputs or files to those providers.

Security and script policy

Nifty Utilities loads a deliberately small, fixed set of code, and none of it has any channel back to us for your data. This is the complete list of what any page is allowed to load:

• Our own files (scripts, styles, images) served from niftyutilities.com.
• Google Analytics and Google AdSense — from googletagmanager.com and googlesyndication.com — for anonymous traffic measurement and the ads that keep the tools free. They load with consent controls and operate at the page level; they never receive the contents of what you type, upload, or calculate.
• One code library host, cdn.jsdelivr.net, used only by a few advanced tools (for example PDF and audio conversion) to load open-source libraries that then run entirely in your browser.

There are no other third-party scripts, no external trackers beyond the two Google services above, and no web fonts or beacons. Expressed as a Content Security Policy, the intended posture is:

default-src 'self';
script-src 'self' https://www.googletagmanager.com https://pagead2.googlesyndication.com https://cdn.jsdelivr.net;
connect-src 'self' https://www.google-analytics.com;
img-src 'self' data: https:;
style-src 'self' 'unsafe-inline';
frame-src https://googleads.g.doubleclick.net;
object-src 'none'; base-uri 'self'

Because the site is hosted as static files, this policy is published here rather than sent as a server header — but you can verify it holds at any time in your browser's developer tools under the Network tab: no request ever carries your tool input off your device.

Analytics and advertising

Nifty Utilities uses Google Analytics 4 to measure site traffic and Google AdSense to display advertising. These Google services may set cookies and process technical data such as your IP address, device type, and the pages you view in order to produce aggregate statistics and to select and measure advertising.

This code runs only as you browse pages. It never receives the files or information you enter into a tool; that processing stays inside your browser as described above, and we never send tool inputs to an advertising or analytics provider.

Cookies and any personalization are denied by default through Google Consent Mode. Where the law requires it, a Google-certified consent message asks for your choice before cookies are set, and you can change that choice at any time through the same control.
