## Subscribing

When you subscribe, the site stores your email address, the name you give (if any), the topics you pick, and the time you signed up. Mac uses them only to send you new research, field manual updates, and news about his video series. Nobody else gets them, and nothing is sold.

To be removed, use the [unsubscribe form](/subscribe#unsubscribe) or email [mac@oxagen.sh](mailto:mac@oxagen.sh). Removal deletes your record.

## The assistant

The assistant sends your question to a language model through Vercel's AI Gateway to write an answer. The site does not store your conversations. It counts requests per network address for a short time to stop abuse, and then forgets them. Do not type personal or secret information into the assistant.

## Saved in your browser

Your theme choice, the checklist items you tick in the field manual, and your self-assessment answers stay in your own browser's storage. They never leave your device.

## Hosting

The site runs on Vercel. Vercel keeps standard server logs, such as request times and network addresses, to run the service.
