Privacy Policy

Last updated: June 9, 2026. Simple Number Tools is designed to be used without an account, login, or student profile.

Information We Do Not Ask Children to Provide

We do not ask children to create accounts, submit homework, upload files, enter full names, share school names, or provide contact details to use calculators, worksheets, or generators.

Children's Privacy

Simple Number Tools may be used by children for educational practice. Children under 13 should use the site with a parent, guardian, teacher, or tutor. If you are a child, do not send us personal information. If a parent or guardian believes a child has sent personal information to us, reach us through our contact page and we will delete it where reasonably possible.

Calculator and Worksheet Inputs

Calculator values and generated worksheet settings run in your browser. We do not require those values to be submitted to a server to use the tools.

Contact Form

Our contact page uses a Google Form to receive messages. When you submit it, the information you choose to include is sent to and stored by Google on our behalf and is handled under Google's privacy terms. The form does not require you to sign in, and the email field is optional (only if you want a reply). Please avoid sending sensitive information. We use submissions to respond to questions, fix errors, handle privacy requests, and improve the site.

Cookies, Analytics, and Advertising

We do not set analytics or advertising cookies until you accept them. On your first visit a small cookie banner asks for your choice; until you accept, Google's tags run in a consent-denied mode that does not store cookies. You can decline to keep them off, and your choice is remembered on your device so you are not asked again.

We also use Ahrefs Web Analytics, a privacy-focused service that measures aggregate traffic without cookies and without collecting personal data. Because it sets no cookies it does not require consent, but we still honor your choice: if you decline in the cookie banner, it is turned off too.

The site reserves space for ads and may later use advertising partners such as Google AdSense. Advertising and analytics services may use cookies or similar technologies to measure visits, prevent abuse, personalize or limit ads where permitted, and improve ad quality.

When ads are enabled, advertising partners may collect information such as device type, browser, approximate location, pages viewed, and interactions with ads. We will not ask children to click ads or provide personal information for ads.

Third-Party Links

Some pages may link to third-party resources. Their privacy practices are controlled by those third parties, not by Simple Number Tools.

Hosting

The site is hosted on Cloudflare Pages. As the hosting and content-delivery provider, Cloudflare processes technical data such as IP addresses and request logs to deliver the site and protect it from abuse. This is handled under Cloudflare's privacy terms.

Data Security

We use reasonable technical and organizational steps to protect information, but no website can guarantee perfect security.

Parent and Guardian Requests

Parents or guardians may contact us to ask privacy questions, request deletion of a child's personal information if we have received it, or report a concern about child-directed content.

Changes to This Policy

We may update this policy as the site changes. The updated date will show when the policy was last revised.
