Hosting and server logs

The website is hosted by Cloudflare, Inc. Each time you visit the site, the server may record technical connection data (including IP address, date and time, browser type) to keep the service secure and working.

Statistics

I measure traffic with Cloudflare Web Analytics, which does not use cookies and does not build visitor profiles.

TradingView charts

The interactive charts in lessons are TradingView widgets. When you scroll to a chart, your browser loads a script from TradingView servers, which may set their own cookies and process connection data (including your IP address) under the TradingView privacy policy.

Support through buycoffee.to

The "Buy a coffee" button leads to buycoffee.to. That service handles the payment and the related data under its own rules; I have no access to payment data.

Fonts

Fonts are served from the same server as the website and are not downloaded from external services.

Your rights

You have the right to access your data, rectify it, erase it, restrict its processing, port it and object to it, as well as the right to lodge a complaint with the President of the Personal Data Protection Office (UODO).
