Privacy, plainly

Effective 31 October 2026

The worksheet maker works on your device and does not ask for student accounts or personal information.

Worksheet settings and files

Your number ranges, worksheet title and other settings are processed in your browser. Numberleaf does not send those inputs or the generated PDF to an application server. Name and date lines are blank. Avoid putting personal or sensitive information into a worksheet title, especially if you intend to share the downloaded file.

Local state

The maker keeps the current settings in page memory. Reloading or leaving the page resets the worksheet. Numberleaf does not use application cookies or browser storage to remember worksheet settings.

Website hosting and access

Your browser requests the website’s pages and assets from its hosting provider. The provider may process ordinary connection information, such as IP address, browser information and access logs, to deliver and secure the website. If you visit through an owner-only preview, access may also require a ChatGPT sign-in managed by the hosting platform. Those platform functions are separate from the worksheet maker.

Analytics and advertising

This site is being prepared for Google AdSense. Advertising is not currently enabled: this release does not load advertising or analytics scripts or use third-party tracking through the worksheet maker. Public publisher verification information is included so Google can check the site. Before advertising is enabled, this notice and any required privacy choices will be updated to explain the advertising services in use.

External links

Guides may link to external help pages. Visiting those pages is subject to their own privacy practices. Numberleaf does not control external websites.

Contact

For questions about Numberleaf, corrections or privacy requests, email huzifan08@gmail.com. Please do not send student names, class lists or other sensitive information.
