Privacy Policy

Effective date: 26 September 2026. Applies to the Smart Zebra mobile app for iOS and Android.

1. Who we are

Smart Zebra is a learning app for young children, made by Lana Development ("we", "us"). This policy explains what data the app handles, why, and what choices you have. Questions and requests: info@smartzebra.com.ua.

2. Children first

The app is designed for children and is meant to be set up and used together with a parent or guardian. We keep data collection to what the app needs to work:

• no registration and no accounts: the app works without signing in;
• no third-party advertising and no advertising identifiers;
• no chats, social features or public profiles;
• purchases, the parent's report and external links sit behind a parental gate;
• a parent or guardian sets up the child's profile and provides any details about the child.

If you believe a child has provided personal data to us without a parent's involvement, write to us and we will delete it.

3. What data we handle

Child profile. What the parent enters during setup: the child's name or nickname and avatar, gender, month and year of birth, and the parent's answers about learning goals, the child's skills and habits and the planned learning schedule. The profile is stored on the device. It is used to address the child in the app, to adapt content and to write progress reports.

Learning progress. Levels and quizzes completed, answers, stars and rewards, time spent in lessons, chosen language. Progress is stored on the device only. There is no server copy, so it is not transferred to another device.

Progress reports. When a parent opens the report behind the parental gate, the app sends learning statistics together with the child's name, age, gender and the app language to our report service, which uses an AI language model to write a short summary for the parent. The summary is shown in the app; it is not e-mailed and no account is created. The data is used only to generate that summary.

Purchases. Subscription status, purchased plan and transaction identifiers issued by the App Store or Google Play. Payment is handled entirely by Apple or Google; we never see card numbers or bank details.

Technical and usage data. Device model, operating system and app version, interface language, approximate country (derived once from the IP address to suggest a language), a random installation identifier and app events such as "screen opened", "level completed" or "subscription purchased". Answers given during setup, except the child's name, are attached to these events so we can see which parts of the app work for which age groups. None of this is linked to a name, e-mail address or account. When the app downloads lessons or requests a report, the servers see the IP address of your connection, as with any use of the internet.

Attribution. On iOS we use Apple's SKAdNetwork, which reports installs to ad networks in an aggregated form without identifying devices. On Android we read the Google Play install referrer, which tells us which campaign led to the install. Neither uses the advertising ID.

Reminders. Learning reminders are scheduled on the device itself; they do not send data anywhere.

4. Why we use data and on what basis

• to run the app, deliver lessons and keep purchases working — performance of our agreement with you;
• to write a progress report — your request, each time you open the report;
• to understand usage, improve content and keep the app safe and stable — our legitimate interest in running the service well;
• to comply with law, for example tax and accounting rules for purchases.

5. Who processes data for us

We do not sell personal data and do not share it for advertising. We use these providers, each bound by a contract to process data only for us:

• Apple App Store and Google Play — app distribution, purchases and subscriptions;
• RevenueCat — subscription status across Apple and Google, under an anonymous identifier;
• Mixpanel — usage analytics under an anonymous installation identifier;
• Google Cloud Storage — delivery of downloadable lessons; Google Firebase — remote app configuration (no Google Analytics);
• Vercel — hosting of our report service; an AI language model provider — writes progress summaries and does not use this data to train its models;
• ipapi.co — one-time country lookup from the IP address to suggest a language.

We may also disclose data when the law requires it or to protect the rights and safety of users.

6. Where data is stored and for how long

The child's profile, learning progress and generated reports live only on your device and are removed when you delete the app. We do not store report requests on our servers. Usage analytics and purchase records are kept on our providers' servers in the European Union and the United States for as long as we need them to understand how the app is used and to meet legal obligations, and are deleted on request.

7. Your rights

You can ask us to access, correct, export or delete personal data, to restrict or object to its use, and to withdraw consent. Write to info@smartzebra.com.ua; we answer within 30 days. Because the app has no accounts, we cannot see who is behind an installation, so we may ask for details that help us find the data, such as the platform and the approximate dates of use. You can also complain to your data-protection authority. Subscriptions are cancelled in your App Store or Google Play account settings, not by deleting the app.

8. Security

Data travels over encrypted connections and is stored with access limited to what running the service requires. No system is perfectly secure; if a breach affects your data, we will inform you as the law requires.

9. Changes

When this policy changes, we update the date above and, for material changes, tell you in the app before they apply.
