This policy explains how Useful One-Page Tools handles data when you use the site.
Useful One-Page Tools provides small browser-based utilities. The site does not require account creation, user profiles, paid memberships, or login forms. You can open the pages and use the tools without intentionally submitting personal account information to this site.
Some technical data may still be processed by normal website infrastructure, analytics, security, and advertising services.
Most tool inputs are processed locally in your browser. Examples include pasted text, URLs, dates, time zones, JSON, and calculator numbers. These inputs are generally used to produce the result shown on the same page.
Do not paste secrets such as passwords, private tokens, API keys, confidential documents, or sensitive personal information into any public website tool unless you have verified the handling yourself.
The site may use analytics and hosting logs to understand aggregate usage patterns, detect errors, and improve high-value pages. This can include page URL, referrer, country or region, browser type, device information, approximate timestamps, and similar technical information.
Analytics are used to improve the site, for example by identifying which time-zone tools or web checks need better examples and clearer instructions.
The site may use Google AdSense or similar advertising services. Advertising providers may use cookies, device identifiers, IP address, browser information, and page context to provide, limit, measure, or personalize ads depending on your settings and applicable law.
You can manage cookies and ad personalization through your browser settings and Google advertising controls. Third-party providers are responsible for their own privacy practices.
Some pages link to official product, pricing, or documentation pages. If you click an external link, that destination site may receive information such as your browser, IP address, and the referring page. Their privacy policies apply after you leave this site.
For privacy questions, corrections, or removal requests related to this site, use the contact page and include the relevant page URL.
