What we collect
If you send us a message through the contact form, we collect the name, email address and message you type. If you use the AI tutor, the questions you type are sent to Anthropic’s API so it can answer them. Course progress, when you have it, is stored in your own browser, not on our servers.
What we do not do
We do not sell your information, rent it, or trade it. We do not run advertising trackers or third-party ad pixels on this site. We do not ask for payment information anywhere on this site, because every course here is free.
Who we share it with
Only the services required to run the site: Vercel (hosting and request logs), Anthropic (the AI tutor), and Resend (delivering contact-form email to us). Each of them sees only what is needed to do that job.
AI use
This site is built and run with AI, reviewed by a person. The tutor is an AI model and can be wrong. Nothing it says is legal, financial, tax, clinical, or investment advice.
Deleting your information
Email jonathan@tdibroker.com and ask. We will delete what we hold and tell you when it is done.
