Privacy policy

AI Bytes (aibytes.app) runs hands-on AI engineering courses. This page explains what we collect when you use the course at learn.aibytes.app, why, and the choices you have. Questions: aibytesapp@gmail.com.

If you don't sign in

Your progress, notes, quiz answers and the code you write are saved only in your browser on this device. They are not sent to us.

If you sign in

• Account: your email address and name. If you sign in with Google, Google shares your name, email and profile picture with our sign-in provider; we store your email and name.
• Your course work: completed steps, notes, quiz attempts and the code you change in the course workspace, so they follow you to any device where you sign in.
• Activity history: a dated record of what you completed (for example "finished Lesson 1"), used to show your progress and, if your employer gave you a seat, your completion summary.

Live AI model calls

When you switch a lesson to "Live model", your question and the course text it needs are sent through our server to OpenRouter and the model provider it routes to, so a real model can answer. We don't store the content of these calls; our logs keep only the model, the result status, token counts and timing.

If you add your own OpenRouter key under "Model access", it stays in your browser (this tab, or this device if you tick "Remember"). It is sent to our server with each live call, used for that call only, and never stored or logged.

How we use your information

• To run the course, save your progress and keep it in sync across your devices.
• If your employer gives you a seat: to show your team admin a completion summary (lessons completed, best quiz score, time spent, last active). Admins don't see your notes, your code or your individual quiz answers.
• To keep the service secure and stop abuse (for example rate limits on live model calls).
• To improve the course.

We don't sell your information, and we don't use advertising trackers.

Who processes it for us

• Clerk: sign-in and account security.
• Neon: our database (your account, progress, code and activity history).
• Vercel: hosting. Like any website, it processes IP addresses and request logs for security and operations.
• OpenRouter and model providers: only for live model calls you make.
• Google: only if you choose to sign in with Google.

These providers store data in the United States.

Your choices

• Download your data: Account page → Download my data (everything we store about you, as a file).
• Reset your progress or delete your account on the Account page. Deleting your account removes your account, progress, code and activity history. Copies may remain in our providers' backups for a limited time before they expire.
• For anything else, email aibytesapp@gmail.com.

Children

The course is for working professionals and is not directed at children under 16.
