Privacy Policy

1. Information you give us

2. Information collected as you use the Service

• Learning activity: courses joined, videos watched and your position in them, topics completed, quiz attempts and scores, downloads, assignments, and token use.
• Live tuition: your class timetable, whether you said you would attend, whether you joined a class (and when), and attendance marked by teachers.
• Device and technical data: device model, operating system, app version, browser, language, IP address, and crash and error reports.
• Notification tokens so we can send reminders and alerts to your device (you can turn notifications off).
• Whether you are using the website or the mobile app, so help and instructions match what is on your screen.

3. How we use information

4. Learners and children

Estudy is designed for secondary school learners, many of whom are under 18. Learners under 18 should use Estudy with the knowledge and consent of a parent or guardian. We do not knowingly collect information from children under 13 without the consent of a parent or guardian; if we learn that we have, we will delete it.

Parents and guardians who link to a learner can see that learner's learning progress, assignments, purchases made for them, tuition timetable and attendance. They cannot see the learner's password, and cannot join live classes or answer attendance on the learner's behalf.

We do not use learners' learning data for advertising, and we do not sell it.

5. AI features

AI Solve and the Estudy Support assistant are powered by Google Gemini. What you send to them (for example a photo or text of a question, or a support message), together with limited context such as your curriculum or country, is sent to Google to produce an answer. We keep your AI documents and chat history in your account so you can see them again. Please do not include passwords, PINs or other sensitive personal details in AI requests.

6. Who we share information with

We share personal information only with service providers who help us run Estudy, only for that purpose, and under agreements that require them to protect it:

• Your teachers see what they need to teach you, such as your name, assignment submissions and class attendance.
• Linked parents and guardians see the information described in section 4.
• We may disclose information if required by law or a court, or to protect the safety of learners, our users or the public.
• If Estudy is reorganised, merged or sold, information may pass to the new owner, who must keep protecting it under this policy.

7. International transfers

Some of our providers store or process information outside Zambia. When they do, we rely on their contractual and security commitments to protect it to a standard consistent with Zambian law.

8. Cookies and similar technologies

The website uses a secure, http-only session cookie to keep you signed in; without it you cannot use your account. We also store small preferences in your browser, such as light or dark theme and which linked child a parent last selected. The mobile app stores similar settings on your device. Advertising and analytics partners in the mobile app may use device identifiers, which you can limit in your device's privacy settings.

9. How long we keep information

• Account and learning data: while your account is active, and for a short period after deletion to complete backups and resolve disputes.
• Payment and invoice records: as long as tax and accounting law requires.
• Attendance records, AI documents and chat history: while your account is active, unless you delete them sooner.
• Crash and technical logs: for a limited period, then deleted or anonymised.

10. How we protect information

We use encryption in transit (HTTPS), hashed passwords, access controls, and the principle of least access for staff. Paid files are delivered through private, expiring links tied to your account rather than public addresses, and class links are only released to enrolled learners while a class is running. No system is perfectly secure, so please keep your password private and tell us straight away if you notice anything suspicious.

11. Your rights and choices

Depending on the law that applies to you, you may have the right to:

• access the personal information we hold about you and get a copy of it;
• correct information that is wrong or incomplete (much of it you can edit in your profile);
• delete your account and personal information (from your profile in the app, or by contacting us);
• object to or restrict certain processing, or withdraw consent where we rely on it, for example for notifications or advertising;
• complain to the Data Protection Commission of Zambia or your local data protection authority.

12. Other policies

Our other apps have their own privacy policies: Math Solutions (/privacy/math-solutions) and Papers & Quizzes (/privacy/papers-and-quizzes). Links to other websites, such as payment pages or class platforms, are covered by those websites' own policies.

13. Changes to this policy

We may update this Privacy Policy. The latest version is always on this page with its effective date and version number, and we will tell you in the app, on the website or by email about important changes.
