Privacy Policy

Last updated: February 21, 2026

AIBlack ("we", "our", or "us") operates the BTTLingo mobile application (the "App"). BTTLingo is an educational tool that helps learners in Singapore prepare for the Basic Theory Test (BTT) — the written component of the Singapore driving licence examination. The App offers a card-based question review system covering all official BTT topic categories, a timed mock-exam mode, and a multi-language interface (English, Simplified Chinese, Malay, and Tamil) so that learners can study in their preferred language. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.

1. Information We Collect

1.1 Automatically Collected Information

When you use the App, certain information is collected automatically, including:

1.2 Location Data

We do not collect precise location data. We may infer your approximate region from your device settings or IP address solely to provide localised content and to comply with regional advertising regulations.

1.3 Advertising Data (Google AdMob)

The App uses Google AdMob to display advertisements. Google AdMob may collect and process the following data on our behalf:

This data is governed by Google's Privacy Policy. We do not receive or store this advertising data ourselves.

2. How We Use Your Information

We use the collected information to:

3. Third-Party Services

Our App integrates the following third-party services that may collect information independently:

Each third-party service operates under its own privacy policy. We encourage you to review their policies for more information.

4. Advertising & Tracking Transparency

The App displays advertisements provided by Google AdMob. On iOS, the App requests permission to use the Advertising Identifier (IDFA) via Apple's App Tracking Transparency (ATT) framework before any personalised ads are shown. If you decline tracking permission, only non-personalised ads will be displayed. You may change this permission at any time in Settings → Privacy & Security → Tracking.

You may also opt out of personalised advertising globally through your device settings or at Google's Ad Settings.

5. Data Retention & Local Storage

Study progress, exam history, and language preferences are stored locally on your device using browser localStorage. This data is never transmitted to our servers. It is deleted automatically when you uninstall the App. Advertising-related data retained by Google AdMob is subject to Google's own retention policies.

6. Data Security

We implement reasonable technical and organisational measures to protect your information. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

7. Children's Privacy

The App is an educational tool intended for learners of driving age and above. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided personal information, we will promptly delete it. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at the address below.

8. Your Rights
