Privacy Policy
Utility Stack provides free browser-based calculators, converters, generators, and informational tools. This policy explains what information may be collected when you use this website, including analytics and advertising technologies.
Tool inputs
Most Utility Stack tools run in your browser. Inputs such as calculator values, generated passwords, random picks, text conversions, and similar tool data are not sent to our server by the tool code unless a page clearly says otherwise.
Analytics
We use Cloudflare Web Analytics to understand aggregate traffic, page views, device types, referring pages, and general usage patterns. Analytics help improve the site and do not replace professional advice.
Advertising and cookies
This site displays advertising through Google AdSense. Google and its advertising partners may use cookies, web beacons, device identifiers, or similar technologies to serve ads, limit repeated ads, measure ad performance, detect fraud, and improve advertising services.
Depending on your location, settings, and consent choices, ads may be personalized or non-personalized. Personalized ads may use information such as previous visits to this or other websites. Non-personalized ads may still use cookies or similar technologies for basic ad delivery, frequency capping, aggregated reporting, and fraud prevention.
Google advertising partners
Google may work with third-party advertising technology providers to show ads on this site. Those providers may collect or receive information from your browser or device under their own privacy policies. You can review Google's advertising information and controls through Google's ad settings and privacy resources.
Your choices
You can manage cookies through your browser settings. You can also use Google's ad controls to review or change ad personalization settings. Additionally, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Digital Advertising Alliance (DAA) opt-out portal or their local regulatory choices page. Blocking cookies may affect some advertising features, but the core Utility Stack tools are designed to work without requiring you to create an account.
Data we do not intentionally collect
Utility Stack does not intentionally collect account passwords, tax returns, government ID numbers, bank logins, payment card numbers, or health records. Do not enter sensitive personal information into free-form tools unless a page clearly explains why it is needed.
Third-party links
This site may link to IRS pages, exchange-rate providers, code libraries, documentation, or other third-party websites. We are not responsible for the privacy practices or content of those external sites.
Contact
For privacy questions or correction requests, use the contact information on the Contact page.
Children's privacy
This website is intended for general audiences and is not designed to collect personal information from children.
Changes
We may update this privacy policy as the site adds analytics, advertising, or additional tools. The effective date above will be updated when material changes are made.
