A mostly static experience
The learning pages and calculators are designed to work without an account. Calculator inputs are processed in the browser and are not sent to a server by the site code. The paper trading simulator stores its sample portfolio in browser local storage; it is not an account database.
GitHub Pages or a future hosting provider may process technical request data such as IP address, user agent and timestamps under its own policies.
Email and support
If you email the address listed on the Contact page, the mail provider may retain the message and address so a reply can be sent. Do not include recovery phrases, private keys, passwords or payment details. Keep correspondence only as long as needed to handle the request and meet legal obligations.
Future services
If analytics, advertising, embedded videos, newsletter tools or live market data are added, this policy must be updated before those services are enabled. The site should explain what is collected, why it is used, the legal basis where relevant, retention and user choices.
