Privacy Policy – KTS AI Tutor (Arm Offline AI Tutor)

KTS ("we", "us", "our") built the KTS AI Tutor / Arm Offline AI Tutor app as a free educational application. This app runs a small AI model entirely on your device and does not require any network connection to work.

This page explains what information is (and is not) collected when you use the app.

Information we collect

We do not collect, store, or share any personally identifiable information (PII) about you.

Specifically:

• No account or login is required.
• We do not collect names, email addresses, phone numbers, or contact data.
• We do not collect your typed questions or chat history.
• We do not collect device identifiers, advertising IDs, or precise location.

All text you type into the app stays on your device and is only used locally to generate a response from the on-device AI model.

Data processed on your device

KTS AI Tutor runs a tiny transformer model locally on your Arm-based Android device using PyTorch Mobile Lite. The model processes your questions in memory and returns an answer. This processing happens entirely on your device; we do not send this data to any server.

The app may store the AI model file in internal storage so it can be loaded quickly, but this file does not contain any of your personal data.

Third-party services

The app does not integrate any analytics SDKs, advertising SDKs, or third-party tracking services.

PyTorch Mobile Lite is used purely as an on-device runtime library; it does not send data to external servers as used in this app.

Children's privacy

KTS AI Tutor is intended for students and adult learners. We do not knowingly collect personal information from children under the age of 13. If you believe that a child has provided us with personal information, please contact us so we can take appropriate action.

Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
