Reader contributions
How WBF
stays free.
A useful place to return to.
For everyone.
Optional reader contributions help pay for the research, tools and upkeep behind WBF. They keep the guides, My Fog notebook and games available to the next person who needs them.
The system behind WBF
The things you can use today.
Read a guide, save a question, or take a break with a game. Each part of WBF gives you something useful to come back to.
Your My Fog notebook
Keep notes, saved checks and questions in one place. Sign in to save your notebook across devices.
Games at your own pace
Try recall, word-finding and working-memory games. Start with an easy level and play without a timer.
A way into your lab results
Look up the results and ranges on your blood-test report.
Something to take to an appointment
Use doctor handouts and prepare the questions you want to ask.
The work behind the information
See how WBF handles sources, reviews and corrections.
You can use WBF whether or not you contribute. A contribution supports the whole site.
Privacy and independence
Your privacy is not for sale.
WBF does not sell or rent personal information for advertising or marketing. Contribution records stay separate from My Fog and other health information.
Public pages do not use display advertising, affiliate links or third-party marketing pixels.
Contributions do not buy medical advice or editorial influence. Personal listings, quotes and stories are optional and reviewed. Organisations can buy a clearly labelled supporter listing in a broad funding band. Their exact totals stay private, and no organisation gets ranked. See the supporter listing rules.
