Cookie Policy

Last Updated: July 21, 2026

1. What are Cookies?

Cookies are small text files that are stored on your computer or mobile device when you visit a website. They are widely used to make websites work more efficiently and provide information to the site owners. At Utility Spark, we strive to keep our footprint minimal, honoring our privacy-first philosophy.

2. How We Use Cookies

Because the vast majority of Utility Spark's tools operate entirely locally in your browser using local APIs and WebAssembly, we do not require complex tracking cookies to provide our core services. We primarily use cookies for two reasons: saving your interface preferences and supporting the site through advertising.

3. Essential & Functional Cookies

These are cookies (or local storage values) that are strictly necessary for the website to function correctly. They include:

  • Theme Preferences: Saving your preference for Light or Dark mode.
  • Consent State: Remembering whether you have accepted or customized your cookie preferences via our Cookie Settings.

Because these are essential for the site's operation and basic UI preferences, they cannot be disabled in our systems.

4. Third-Party Advertising Cookies (Google AdSense)

To keep Utility Spark free for all users without requiring accounts or subscriptions, we utilize Google AdSense to display advertisements. Google and its partners use cookies to serve ads based on your prior visits to Utility Spark and other websites.

  • Google's use of advertising cookies enables it and its partners to serve targeted ads.
  • These cookies do not grant us access to your personal information.
  • You can opt out of personalized advertising by visiting Google's Ads Settings.

5. Managing Your Cookies

You can review and modify your specific cookie preferences for Utility Spark at any time by visiting our dedicated Cookie Settings page.

Furthermore, most web browsers allow some control of most cookies through the browser settings. You can set your browser to refuse all or some browser cookies, or to alert you when websites set or access cookies. Please note that if you disable essential cookies, some parts of this website (like the Dark Mode toggle) may not function properly.
