Privacy Policy

Last updated: September 8, 2026

What we collect

• Purchase details. When you buy, our payment provider (the merchant of record) shares your name, email, and order reference so we can issue and service your license. We never see or store your card details.
• License data. Your license key, a device fingerprint used for the one-computer limit, activation timestamps, and annual access expiry when applicable. Your browser stores the device identifier and signed access confirmation locally.
• Access delivery. We send purchase-access and recovery emails. Access links are single-use and expire after 30 minutes. A temporary checkout proof is kept in this browser tab's session storage to check payment status, not to grant access. Private access tokens are removed from the address bar before verification and are not used for analytics.
• Support and feedback. Whatever you write to us, with the contact details you include.
• Traffic counts. Anonymous page-view counters (page, day, referrer source). No cookies, no cross-site tracking, no advertising pixels, no sale of data.

What we don't do

We don't run third-party analytics or ad trackers on this site, we don't sell or share personal data for marketing, and we don't send marketing email unless you explicitly opted in.

Where data lives

License records are stored on our hosting provider's infrastructure (Fly.io) in the United States. Payment records live with the payment provider under their own privacy policy.

Your choices

You can ask us to show or delete the data we hold about you (deleting license data ends course access). Contact us via the support page.

Course progress

Your learning progress, answers, and simulator sessions are stored locally in your browser, not on our servers. Clearing site data erases them.
