What we collect
This static educational website does not have sign-up forms, advertising trackers or our own visitor-account database. The optional observation diary uses your browser’s localStorage to hold notes on your own device. Entries are not sent to this website’s owner or a remote server by the diary JavaScript.
How to delete your notes
Open the diary and choose Clear Entries. Clearing your browser storage may also erase saved records. Printed copies are your responsibility. Do not put private medical records or identifying information into a device that is shared with others without considering who can access it.
Hosting and external references
The website is distributed using a hosting provider that may maintain technical logs and apply its own privacy policies. When you follow an external research link, the destination site may collect information under its own policy. We do not control the practices of third-party websites. The page design may also request a web font from Google Fonts, subject to that service’s policy. This information describes the website as delivered; it is not a promise about platform-level logging.
