What these pages do
The website consists of static pages, local images, a compiled stylesheet, and a small script for navigation, printing, and reading progress. These site files do not include advertising pixels, analytics trackers, newsletter forms, account registration, or search inputs. The script does not set cookies or store browsing data in local storage.
The hosting service may process ordinary connection information, such as an IP address, request time, and requested page, according to its own configuration and practices. The absence of tracking scripts in these pages does not mean that a web server handles no technical request information.
Email links
Selecting [email protected] opens your chosen email application where supported. The website does not submit a message for you or save a draft. Messages you choose to send are handled through the email services involved in that exchange, not a web form on this site.
Do not send unnecessary sensitive information such as payment-card details, passport copies, or medical records. Include only the context needed for your question or factual correction. Visit Contact for the types of inquiries relevant to this editorial guide.
External resources
The About page includes one external link to Wikipedia’s Brazilian jiu-jitsu article. Following that link takes you to a separate website with its own practices and terms. External resources are not embedded as videos, advertising units, or interactive widgets in these pages.
RSS and printing
The RSS feed is a public file that a feed reader can retrieve. Using it does not register an email address with this site. The packing checklist’s print button invokes your browser’s print interface; it does not send a completed checklist or other information to a server.
Questions about the site
