What we collect
MatheLinux stores account email, authentication identifiers, course progress, lesson completions, practice attempts, submissions, mentorship bookings, talk registrations, payment ledger events, and support messages you send us.
Payment data
Automated card payments are handled by payment providers such as Lemon Squeezy or Paystack. MatheLinux stores provider event IDs, product IDs, access state, and audit metadata needed to unlock or lock access. We do not store full card numbers.
Learning analytics
We use learning and page-view events to understand course usage, drop-off, signups, and paid conversion. Page-view tracking is first-party and limited to path, referrer, title, coarse device, country when available, and an anonymous browser ID.
How data is used
Data is used to operate the LMS, protect paid content, provide support, improve curriculum quality, verify certificates, and maintain billing records.
Retention
Payment and access logs are retained for audit and support. Learning progress and submissions remain attached to the account unless deletion is requested and legally permitted.
Contact
For privacy or account deletion requests, use the current verified contact channel shown on the Support page. Requests should come from the email attached to the account.
