What we collect
When you create an account, we collect account details provided by your authentication provider, including your email address and display name if available. We also store usage data needed to run the product, including lesson reads, checklist progress, completion state, and time spent learning.
We do not collect payment card details. Payment information is handled directly by Stripe. We store only billing metadata required to provide membership access, such as customer identifiers and subscription status.
We use an authentication session cookie so you can stay signed in. We do not use tracking cookies. We do include one Carbon Ads script for free users, and that script may use its own standard ad-delivery mechanisms.
