Privacy
Effective October 31, 2026
This publisher website has no account system, forms, advertising scripts or analytics trackers. It does not set application cookies or store visitor preferences.
Hosting requests
Serving a webpage requires your browser to send ordinary network information, including an IP address and requested URL, to the hosting provider. The provider may process security and operational logs under its own policies. Browser-local file processing does not eliminate these ordinary website requests.
Product websites
Each product has its own privacy page describing its actual processing and storage. Local processing means the product does not upload selected file contents as part of its supported workflow. Follow the product's instructions for downloaded files and shared devices.
External links
Opening an external source or merchant link takes you to a separate service with its own privacy practices. No affiliate tracking is currently configured in this build.
Production hosting
These pages are hosted through ChatGPT Sites on Cloudflare. Hosting may set security cookies such as __cf_bm and process ordinary request metadata to protect and deliver the website. These hosting functions are separate from the application and do not receive the files or worksheet inputs processed locally. Hosting notice reviewed November 1, 2026.
