Privacy Policy

Data we collect

We collect the minimum needed to run the service:

• Account data: your email and display name.
• Learning data: course progress, training results, spaced-repetition schedule.
• Subscription data: your subscription status (payments are processed by a third party; we never store card details).
• Technical data: a public device key used to protect encrypted course content, and basic session identifiers.

How we use data

• Deliver lessons and sync your progress across devices.
• Personalise review and spaced-repetition sessions.
• Protect paid content and decrypt it on your authorised device.
• Improve the product and support you when needed.

Sharing

We do not sell your data. We share it only with trusted providers (hosting, payment processing) as needed to operate the service, under agreements that protect your data.

Content protection & encryption

Course content is encrypted at rest. A key pair is generated on your device and its public key is registered with us so the decryption key is delivered only to your device. Decrypted content stays in device memory during use.

Your rights

• Access or correct your data.
• Delete your account and associated data.
• Export your progress data.
• Withdraw consent to marketing messages at any time.

Retention

We keep your data while your account is active. On deletion we remove your personal data within a reasonable period, except where retention is legally required.
