On your device only
- Your theme and language choices.
- Your subjects, level, progress, answers and what you know, used by the learning engine.
- Copies of your course and its next lessons, so they open instantly and offline.
Clearing the site data in your browser removes all of it.
On the server
- The text of a new lesson request, which becomes a public lesson title for everyone. Write subjects, never personal details.
- A daily-rotating one-way tag of your connection, kept for one hour, to apply the hourly limit on new lessons. It cannot be turned back into your address.
- Page-view counts per day, with no detail about who viewed.
- For Pro and Ultra: your email, your plan and a copy of your progress, so every device you sign in to has it.
- For payments: the plan and its status only. PayPal handles the payment itself; Teach Me never sees card or bank details.
- Only when you complete a track: the certificate (subject, track, number of lessons, date), so anyone with its link can check it.
