Privacy Policy
Last updated: 8 November 2026.
ToolsZio ("we", "us", "our") runs a website of free calculators and tools at toolszio.com. This policy explains what data is — and is not — collected when you use it. The short version: the calculators and tools run entirely in your browser. The numbers you type and the files you open are never sent to our server, never stored, and never shared.
1. Information You Enter Into Tools
When you use a calculator or tool on this site, everything you type or upload is processed locally on your own device by JavaScript running in your browser. Loan amounts, salaries, health measurements, text, code, PDFs and images stay on your device. We do not receive, store, or have access to any of it, and we cannot see it even if we wanted to. Closing the page removes it from memory.
2. Information We Do Not Collect
We do not ask you to create an account, and we do not ask for your name, email address, phone number, bank details, or payment information to use any tool. We do not run user accounts, newsletters, or login systems on this site.
3. Contact Messages
If you email us at contact@toolszio.com, we receive your email address and whatever you choose to write. We use it only to reply to you, and we do not sell it or add it to any list. Please do not send passwords, account numbers, or private documents by email — we will never ask for them.
4. Server Logs
Like almost every website, our hosting provider records basic technical information when your browser requests a page: the page requested, the date and time, the type of browser, and an IP address. These logs are used for security and to keep the site running, and they are kept by the hosting provider under its own retention policy. We do not use server logs to identify individual visitors.
5. Cookies and Advertising
This site uses Google AdSense to show advertisements once approved. Google and its advertising partners may use cookies and similar technologies — including the DoubleClick cookie — to show ads based on your visits to this site and other sites. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. You can opt out of personalised advertising at Google Ads Settings and at aboutads.info/choices. If you are in the European Economic Area or the United Kingdom, you will be asked for consent before personalised ads are shown, through a Google-certified consent tool.
We do not set advertising cookies ourselves, and we do not sell personal information. Our advertising partner's use of data is governed by Google's privacy policy.
6. Analytics
We may use a privacy-friendly analytics tool to count visits and see which tools are popular, so we know what to improve. Any analytics used on this site is configured to avoid collecting personal information, and it does not track you across other websites.
7. Children's Privacy
This site is intended for adults. We do not knowingly collect personal information from children under 13. The calculators are educational tools; a child using them should do so with a parent or teacher.
8. Links to Other Websites
Our pages may link to other websites for reference. We are not responsible for the privacy practices of those sites, and we encourage you to read their policies.
9. Changes to This Policy
We may update this policy when the site changes — for example, if we add an analytics tool or change how advertising works. The "last updated" date at the top will change, and the current version will always be on this page.
