Your data in the companion

Your verified email identifies your reader account. The platform stores your book access, chapter progress, saved experiments, and usage records. Publishers can review access and support records using restricted staff accounts.

Saved work

Your notebook is private to your account. You can export and delete experiments from My notebook. Do not submit passwords, confidential customer information, or other sensitive material. Teaching datasets are synthetic.

Live model requests

When you choose a live run, the instructions and input you provide are sent to the configured AI provider. The platform records model and token usage for allowance and cost controls. Saving the prompt and response in your notebook is a separate action. The provider's applicable data-handling terms still apply.

Sessions and service providers

Essential session cookies maintain your login. Authentication, storage, application hosting, email delivery, optional payments, and live AI are supplied by the configured service providers. This application does not add advertising trackers.

Questions and account requests

Use the official TensorLearners contact information supplied with your book or purchase for account-data or support requests. The publisher must maintain its published retention, access, and support policies.
