Privacy Policy

1. Overview

Matematyka ("we", "us", "our") is committed to protecting your privacy. This Privacy Policy explains what personal data we collect, how we use it, and your rights in relation to that data.

By using Matematyka you agree to the collection and use of information in accordance with this policy. This policy applies to all users of the Site, including visitors, registered students, and teachers.

2. What We Collect

We collect the following categories of personal data:

Account information

• First name and last name
• Email address
• Password (stored as a secure hash — we never store your plain-text password)
• Account role (Student or Teacher)
• Exam level preference (e.g. National 5, Higher)
• Profile picture (if you choose to upload one)

Usage and activity data

• Quiz attempts, scores, and answers
• Topics and sections viewed
• Study plan entries
• Personal notes created on the platform
• Bookmarks and saved content

Technical data

• Session data necessary to keep you logged in (stored in a secure server-side session)
• Standard server logs, which may include your IP address and browser information, retained briefly for security and troubleshooting purposes

We do not collect payment information — the Site is entirely free to use.

3. How We Use Your Data

We use the data we collect to:

• Create and manage your account
• Authenticate your login sessions
• Track your quiz progress and show your results on the dashboard
• Provide personalised content based on your exam level
• Enable teacher–student connections when you share your user code
• Send transactional emails such as email verification and password reset links
• Improve and maintain the Site
• Detect and prevent abuse or security incidents

We do not use your data for advertising, profiling for commercial purposes, or any use unrelated to providing the educational service.

4. Data Storage & Security

Your data is stored on secure servers. We implement appropriate technical and organisational measures to protect your personal data against unauthorised access, alteration, disclosure, or destruction. These include:

• Passwords are hashed using a strong one-way algorithm (bcrypt) — your plain-text password is never stored
• Database access is restricted and not exposed to the public internet
• Sessions are managed server-side with secure, HTTP-only cookies
• HTTPS is used to encrypt data in transit

No method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your data, we cannot guarantee absolute security.

5. Sharing Your Data

We do not sell, rent, or trade your personal data to third parties.

Your data may be shared in the following limited circumstances:

• With teachers: If you share your user code with a teacher, they may be able to see your name, progress, and quiz scores within the platform's class management features.
• Service providers: We may use third-party services (such as email delivery providers) solely to operate the platform. These providers process data on our behalf and are required to keep it confidential.
• Legal obligations: We may disclose data if required to do so by law or in response to valid legal requests.

6. Data Retention

We retain your personal data for as long as your account is active or as needed to provide the service. If you delete your account, we will permanently delete all associated personal data — including your profile, progress, notes, and quiz history — within a reasonable period.

Anonymised or aggregated data (which cannot identify you) may be retained for analytical purposes.

7. Your Rights

Depending on your location and applicable law, you may have the following rights in relation to your personal data:

• Right of access: Request a copy of the personal data we hold about you.
• Right to rectification: Update inaccurate or incomplete data — you can do this directly in your account settings.
• Right to erasure: Delete your account and all associated data at any time via the Danger Zone in your account settings.
• Right to restriction: Request that we restrict the processing of your data in certain circumstances.
• Right to object: Object to the processing of your data for certain purposes.

To exercise any of these rights, contact us using the details in section 11. We will respond within a reasonable timeframe.

8. Cookies

We use cookies to keep you logged in and to maintain your session. We do not use third-party tracking or advertising cookies. For full details, please read our Cookie Policy.

9. Children's Privacy

Matematyka is designed for students and may be used by those under 18. We do not knowingly collect more personal data from children than is necessary to provide the service. If you are under 16, we recommend using the Site with the awareness of a parent or guardian.

If you believe a child has provided us with personal data in a way that violates this policy, please contact us and we will take steps to address it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date at the top of this page. We encourage you to review this policy periodically.

Continued use of the Site after changes are posted constitutes your acceptance of the revised policy.
